Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of product processing, and in particular to a positioning jig and a processing device. BACKGROUND

[0002] In the processing of products, the positioning jig is needed to position the to-be-processed rod first, and then the to-be-processed rod is processed to form a product. In the related art, the to-be-processed rod is generally placed horizontally on the positioning jig, and when the to-be-processed rod is clamped and fixed in position, a plurality of clamping assemblies are needed to clamp one to-be-processed rod, and the plurality of clamping assemblies are arranged along the length direction of the to-be-processed rod. After the to-be-processed rod is processed to form a product, the clamping position of the to-be-processed rod generally occupies the material which is discarded, and the plurality of clamping assemblies occupy more clamping positions of the to-be-processed rod, thereby causing more waste of the material of the to-be-processed rod. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a positioning jig and a processing device, which can improve the material utilization rate of the to-be-processed rod.

[0004] According to one aspect of the present application, the embodiments of the present application provide a positioning jig for positioning a to-be-processed rod, the length of the to-be-processed rod extending along a first direction, the positioning jig comprising a feeding assembly and a clamping assembly, the feeding assembly comprising a containing part and a feeding driving part, the containing part having a containing cavity and a containing opening, the containing cavity being in communication with the containing opening, the length of the containing cavity extending along the first direction, the containing cavity being used for containing the to-be-processed rod, the feeding driving part being arranged at the side of the containing cavity away from the containing opening, the feeding driving part being used for driving the to-be-processed rod to extend out of the containing opening along the first direction; the clamping assembly comprising two clamping pieces, the two clamping pieces being arranged at the containing opening, the two clamping pieces being distributed along a second direction, at least one of the two clamping pieces being adjustably arranged along the second direction, so that when the to-be-processed rod extends out of the containing opening, the two clamping pieces clamp the to-be-processed rod outside the containing opening, and the second direction is perpendicular to the first direction.

[0005] The positioning jig can be used in a processing device. A processing mechanism of the processing device processes a to-be-processed rod on a side of the clamping assembly away from the accommodating component to form a product. After one product is processed, the two clamping pieces loosen the to-be-processed rod, and the to-be-processed rod is moved to the outside of the accommodating cavity along the first direction and clamped by the clamping pieces to process the next product until the remaining material of the to-be-processed rod is insufficient to process the product, and the to-be-processed rod is replaced. During the processing of the to-be-processed rod, only one clamping assembly can be provided. The to-be-processed rod moves along the length direction thereof and gradually extends out of the outside of the accommodating cavity to sequentially process and form a plurality of products along the length direction of the to-be-processed rod. Finally, the remaining material of the to-be-processed rod is a clamping position of one end of the to-be-processed rod in the length direction clamped by the clamping assembly, thereby reducing the waste of the material of the to-be-processed rod and improving the material utilization rate of the to-be-processed rod. In addition, the accommodating cavity of the accommodating component plays a guiding and supporting role in the movement of the to-be-processed rod. The to-be-processed rod is placed in the accommodating cavity, and the circumferential side wall of the accommodating cavity surrounds the to-be-processed rod, so that the to-be-processed rod is not easy to fall off during movement.

[0006] In at least one embodiment, the positioning jig further comprises a limiting assembly, the limiting assembly comprising a limiting piece, the limiting piece being located on a side of the two clamping pieces away from the accommodating component, the limiting piece being adjustably arranged to have a limiting position and a separation position. The accommodating opening has an extension path on a side away from the accommodating cavity for the to-be-processed rod to extend out. When the limiting piece is in the limiting position, the limiting piece is located on the extension path and forms a to-be-processed section with a preset length between the two clamping pieces and the limiting piece. When the limiting piece is in the separation position, the limiting piece is separated from the to-be-processed rod.

[0007] By providing the limiting assembly, when the limiting piece is in the limiting position, the to-be-processed rod forms a to-be-processed section with a preset length between the two clamping pieces and the limiting piece. When the to-be-processed rod is placed in the accommodating cavity, the operator manually presses an end of the to-be-processed rod outside the accommodating cavity to a position that can be limited by the limiting piece, without the need for manual observation of whether the to-be-processed rod outside the accommodating cavity extends by the preset length, thereby reducing the difficulty of manual operation, reducing the clamping time of the to-be-processed rod by the positioning jig, and thereby improving the clamping efficiency of the to-be-processed rod.

[0008] In at least one embodiment, the limiting piece is movably arranged along a second direction, the limiting piece having a limiting slot and a limiting opening, the limiting slot and the limiting opening being in communication, and the to-be-processed rod enters the limiting slot after passing through the limiting opening during movement of the limiting piece from the separation position to the limiting position.

[0009] By setting the limiting piece to move along the second direction, the occupying volume of the positioning jig in the first direction is reduced, so that the overall structure of the positioning jig is reasonably arranged, and by setting the limiting slot and the limiting opening on the limiting piece, the to-be-processed rod can smoothly enter the limiting slot during movement of the limiting piece along the second direction.

[0010] In at least one embodiment, the positioning jig further comprises a positioning assembly, the positioning assembly and the limiting assembly are distributed along the second direction; the positioning assembly comprises a positioning piece, the positioning piece is movably arranged so that the positioning piece has a positioning position for pressing on one end of the to-be-processed rod and a release position separated from the to-be-processed rod; the positioning piece has a positioning contact surface for contacting the to-be-processed rod, and the limiting piece has a limiting wall for limiting cooperation with the end of the to-be-processed rod; wherein when the positioning piece is in the positioning position, the distance between the positioning contact surface and the plane where the receiving opening is located is less than the distance between the limiting wall and the plane where the receiving opening is located.

[0011] By setting the positioning piece, when the to-be-processed rod is placed in the receiving cavity, the to-be-processed rod is first placed in the positioning position by the positioning piece, and the limiting assembly is in the separated position at the same time. After the positioning piece is in the positioning position, the limiting piece is controlled to move from the separated position to the limiting position. During the movement of the limiting piece, the limiting piece abuts against the positioning piece and drives the positioning piece to move from the positioning position to the release position. After the limiting piece is in the limiting position and the to-be-processed rod is located in the limiting slot, the feeding driving piece drives the to-be-processed rod to move to a position abutting against the limiting wall, so as to form a to-be-processed section with a preset length between the two clamping pieces and the limiting piece. Then, the two clamping pieces clamp the to-be-processed rod to fix the to-be-processed rod. Then, the limiting piece exits, and the processing mechanism processes the to-be-processed section of the to-be-processed rod.

[0012] In at least one embodiment, the positioning assembly comprises a first mounting piece and a second elastic piece, the first mounting piece has a first mounting cavity, the positioning piece passes through the first mounting cavity and is movably arranged along the second direction, the first mounting cavity has a first inner wall, and the first inner wall is located on the side of the first mounting cavity away from the limiting piece; the second elastic piece is sleeved on the positioning piece, one end of the second elastic piece is connected with the positioning piece, and the other end of the second elastic piece is connected with the first inner wall.

[0013] When the positioning piece is in the positioning position, the second elastic piece is in a free state. During movement of the positioning piece from the positioning position to the release position, the second elastic piece is in a compressed state. When it is necessary to position the to-be-processed rod again, the positioning piece is driven to recover from the release position to the positioning position by the elastic force of the second elastic piece. Compared with setting a driving power source (such as a pneumatic cylinder, a hydraulic cylinder, and an electric push rod), the cost of setting a second elastic piece is lower.

[0014] In at least one embodiment, the two clamping members are divided into a first clamping member and a second clamping member, the second clamping member is movably arranged along the second direction; the first mounting member is movably arranged along the first direction, so that when the positioning member is in the released position, the first mounting member drives the positioning member to move to the first clamping member, and the positioning member is arranged opposite to the second clamping member.

[0017] When the positioning member is in the positioning position, the third elastic member is in a compressed state, and when the positioning member is in the released position, the third elastic member recovers from the compressed state to a free state, and drives the first mounting member and the second mounting member to move downward, so that the positioning member moves to the position abutting against the workpiece to be machined, so that the positioning member and one clamping member clamp the workpiece to be machined. Compared with arranging one driving power source (such as a pneumatic cylinder, a hydraulic cylinder and an electric push rod), the cost of arranging the third elastic member is lower.

[0018] In at least one embodiment, the limiting assembly further comprises a limiting driving structure, the limiting driving structure is connected with the limiting member to drive the limiting member to move.

[0019] By arranging the limiting driving structure, the automatic movement of the limiting member is realized, and the automation degree of the positioning jig is improved.

[0020] In at least one embodiment, the clamping assembly comprises a clamping driving structure, the clamping driving structure is connected with one clamping member to drive the clamping member to move along the second direction.

Specific implementation

[0035] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0036] In the related art, the to-be-processed rod is horizontally placed at the accommodating groove of the positioning jig, and it can be understood that the length of the to-be-processed rod extends along the length of the accommodating groove, and the to-be-processed rod has a clamped position and a to-be-processed position, which are respectively located on both sides of the height / width direction of the to-be-processed rod. The clamped position of the to-be-processed rod is arranged in the accommodating groove, and the to-be-processed position of the to-be-processed rod is located outside the accommodating groove. When the to-be-processed rod is clamped and fixed, a plurality of clamping assemblies need to be arranged to clamp one to-be-processed rod. The plurality of clamping assemblies are arranged along the length direction of the to-be-processed rod and are connected to the clamped position of the to-be-processed rod. After the to-be-processed position is processed to form a product, the height / width of the remaining clamped position of the to-be-processed rod does not meet the processing requirements of the required height / width of the product. Therefore, the material of the remaining clamped position of the to-be-processed rod is generally discarded. The plurality of clamping assemblies occupy more clamped positions of the to-be-processed rod, thereby causing more waste of the material of the to-be-processed rod.

[0037] An embodiment of the present application provides a positioning jig for processing a to-be-processed rod. The length of the to-be-processed rod extends along a first direction. The positioning jig comprises a feeding assembly and a clamping assembly. The feeding assembly comprises an accommodating component and a feeding driving piece. The feeding driving piece is used to drive the to-be-processed rod to move along the first direction. The accommodating component has an accommodating cavity. The length of the accommodating cavity extends along the first direction. The accommodating cavity is used to pass through the to-be-processed rod. The to-be-processed rod is movably arranged along the first direction relative to the accommodating component, so that part of the to-be-processed rod is located outside the accommodating cavity. The clamping assembly comprises two clamping pieces. At least one clamping piece of the two clamping pieces is movably arranged along a second direction. When the to-be-processed rod extends outside the accommodating cavity, the clamping assembly clamps the to-be-processed rod located outside the accommodating cavity. The first direction is perpendicular to the second direction.

[0038] The positioning jig can be used in a processing device. A processing mechanism of the processing device processes a to-be-processed rod on a side of the clamping assembly away from the accommodating component to form a product. After one product is processed, the two clamping pieces loosen the to-be-processed rod, and control the to-be-processed rod to move to the outside of the accommodating cavity along the first direction and clamp the to-be-processed rod by the clamping pieces to process the next product until the remaining material of the to-be-processed rod is insufficient to process the product, and the to-be-processed rod is replaced. During the processing of the to-be-processed rod, only one clamping assembly can be provided. The to-be-processed rod moves along the length direction thereof and gradually extends out of the outside of the accommodating cavity to sequentially process and form a plurality of products along the length direction of the to-be-processed rod. After the last processing, the remaining material of the to-be-processed rod is a clamping position of one end of the to-be-processed rod in the length direction clamped by the last clamping assembly, so that the waste of the material of the to-be-processed rod is reduced, and the material utilization rate of the to-be-processed rod is improved. In addition, the accommodating cavity of the accommodating component plays a guiding and supporting role in the movement of the to-be-processed rod. The to-be-processed rod is placed in the accommodating cavity, and the circumferential side wall of the accommodating cavity surrounds the to-be-processed rod, so that the to-be-processed rod is not easy to fall off during movement.

[0039] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following embodiments and examples can be combined with each other without conflict.

[0040] Please refer to Figure 1 and Figure 2 The embodiments of the present application provide a processing device, which comprises a positioning jig 1 and a processing mechanism. The positioning jig 1 is used for positioning a to-be-processed rod 100. The processing mechanism is arranged on one side of the positioning jig 1 to process the to-be-processed rod 100 on the positioning jig 1.

[0041] In some embodiments, the product is a button, and the processing mechanism comprises a mold. The mold is movably arranged along the first direction. The to-be-processed rod 100 is formed into a button by stamping through the mold.

[0042] Please refer to Figure 1 and Figure 2 In some embodiments, the length of the to-be-processed rod 100 extends along the first direction. The positioning jig comprises a feeding assembly 10 and a clamping assembly 20. The feeding assembly 10 comprises an accommodating component 11 and a feeding driving piece 12. The accommodating component 11 has an accommodating cavity 110 and an accommodating opening 111. The accommodating cavity 110 is in communication with the accommodating opening 111. The length of the accommodating cavity 110 extends along the first direction. The accommodating cavity 110 is used for accommodating the to-be-processed rod 100. The feeding driving piece 12 is arranged on a side of the accommodating cavity 110 away from the accommodating opening. The feeding driving piece 12 is used for driving the to-be-processed rod 100 to extend out of the accommodating opening 111.

[0043] The movement of the to-be-processed rod 100 is realized by the feeding driving member 12, and the feeding driving member 12 plays a role of supporting the to-be-processed rod 100. The receiving cavity 110 of the receiving component 11 plays a role of guiding and supporting the movement of the to-be-processed rod 100. The to-be-processed rod 100 is placed in the receiving cavity 110, so that the circumferential side wall of the receiving cavity 110 surrounds the to-be-processed rod 100, so that the to-be-processed rod 100 is not easy to fall off when the to-be-processed rod 100 moves.

[0044] Please refer to Figure 1 and Figure 2 The clamping assembly 20 includes two clamping members 210, and the two clamping members 210 are arranged at the receiving opening 111. The two clamping members 210 are distributed along the second direction, and at least one of the two clamping members 210 is adjustably arranged along the second direction, so that when the to-be-processed rod 100 extends out of the receiving opening 111, the two clamping members 210 clamp the to-be-processed rod 100 located outside the receiving opening 111. The length of the to-be-processed rod 100 extends along the first direction, and the second direction is perpendicular to the first direction.

[0045] In the specific implementation process, the processing mechanism of the processing equipment processes the to-be-processed rod 100 away from the side of the receiving component 11 of the clamping assembly 20; after one product is processed, the two clamping members 210 loosen the to-be-processed rod 100, and the part of the to-be-processed rod 100 is moved to the outside of the receiving cavity 110 along the first direction and extends out of the receiving cavity 110, and then the clamping member 210 clamps the to-be-processed rod to process the next product, until the remaining material of the to-be-processed rod 100 is insufficient to process the product, and the to-be-processed rod 100 is replaced; in the above processing process of the to-be-processed rod 100, only one clamping assembly 20 can be arranged, and the to-be-processed rod 100 moves along the length direction thereof and gradually extends out of the outside of the receiving cavity 110, so as to sequentially process a plurality of products along the length direction of the to-be-processed rod 100. When processing is completed, the remaining material of the to-be-processed rod 100 is a clamping position of one end of the to-be-processed rod 100 clamped by the clamping assembly 20 in the length direction, thereby reducing the waste of the material of the to-be-processed rod 100 and improving the material utilization rate of the to-be-processed rod 100.

[0046] In some embodiments, the feeding driving member 12 is a first piston cylinder, and a first piston rod of the first piston cylinder is used to contact and connect with the to-be-processed rod 100. Optionally, the first piston cylinder can be a gas cylinder or a hydraulic cylinder or an electric push rod.

[0047] In some embodiments, the feeding assembly 10 further comprises a distance sensor, the first piston cylinder comprises a first piston rod, and the distance sensor is configured to detect the distance of movement of the first piston rod. The distance sensor can be configured to accurately control the distance of movement of the first piston rod, so that the to-be-processed rod 100 can be automatically extended out of the accommodating cavity 110, thereby improving the automation level of the positioning jig.

[0048] In some embodiments, the feeding driving member 12 is a first elastic member, the accommodating cavity 110 has an inner bottom wall 112 located at an end of the accommodating cavity 110 away from the two clamping members 210, one end of the first elastic member is connected to the inner bottom wall 112, and the other end of the first elastic member is configured to be pressed by the to-be-processed rod 100 to drive the to-be-processed rod 100 to extend out of the accommodating cavity 110 by the elastic force of the first elastic member. Compared with the configuration of the feeding driving member 12 as the first piston cylinder, the configuration of the feeding driving member 12 as the first elastic member can reduce the manufacturing cost of the positioning jig.

[0049] Specifically, the first elastic member is a spring.

[0050] In some embodiments, the to-be-processed rod 100 is manually pressed, and whether the to-be-processed rod 100 located outside the accommodating cavity 110 is at a preset length is manually observed.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the positioning jig further comprises a limiting assembly 30, the limiting assembly 30 comprises a limiting member 31 located at a side of the two clamping members 210 away from the accommodating member 11, the limiting member 31 is adjustably arranged, so that the limiting member 31 has a limiting position and a separation position; the accommodating opening 111 has an extension path for the to-be-processed rod 100 to extend out of the accommodating cavity, when the limiting member 31 is at the limiting position, the limiting member is located on the extension path, and the limiting member 31 is in limiting cooperation with one end of the to-be-processed rod 100 located outside the accommodating cavity 110, and the to-be-processed rod 100 forms a to-be-processed section with a preset length between the two clamping members 210 and the limiting member 31; when the limiting member 31 is at the separation position, the limiting member 31 is separated from the to-be-processed rod 100.

[0052] By setting the limiting component 30, when the limiting component 31 is in the limiting position, the rod to be processed 100 forms a processing section of a preset length between the two clamping components 210 and the limiting component 31. When the operator places the rod to be processed 100 into the receiving cavity 110, he / she can manually press the end of the rod to be processed 100 located outside the receiving cavity 110 to a position that can be limited by the limiting component 31. There is no need to manually observe whether the rod to be processed 100 located outside the receiving cavity 110 extends beyond the preset length, thereby reducing the difficulty of manual operation, reducing the clamping time of the positioning fixture on the rod to be processed 100, thereby improving the clamping efficiency of the rod to be processed 100, and thus shortening the entire process time of the processing equipment to process the rod to be processed 100, thereby improving the processing efficiency of the processing equipment.

[0053] Please see Figure 1 and Figure 3 In some embodiments, the limiting member 31 is movably disposed along the second direction. The limiting member 31 has a limiting groove 310 and a limiting opening 311, which are connected. During the process of the limiting member 31 moving from the separated position to the limiting position, the rod to be processed 100 passes through the limiting opening 311 and enters the limiting groove 310. By setting the limiting member 31 to move along the second direction, the volume occupied by the positioning fixture in the first direction is reduced, making the overall structure of the positioning fixture more reasonable. Furthermore, by providing the limiting groove 310 and the limiting opening 311 on the limiting member 31, the rod to be processed 100 can smoothly enter the limiting groove 310 during the movement of the limiting member 31 along the second direction.

[0054] Please see Figure 3 Furthermore, the limiting opening 311 includes a first opening segment 3111 and a second opening segment 3112, the first opening segment 3111 and the second opening segment 3112 are connected, the second opening segment 3112 is disposed opposite to the limiting wall 312, the first opening segment 3111 is disposed opposite to the rod to be processed 100, and the first opening segment 3111 and the second opening segment 3112 form an L-shaped structure; wherein, the height of the first opening segment 3111 along the first direction is a preset length.

[0055] Specifically, the height of the first opening segment 3111 can be set according to the specific requirements of the product (button).

[0056] Please see Figure 1 and Figure 2In some embodiments, the positioning fixture further includes a positioning component 40, which and a limiting component 30 are distributed along a second direction. The positioning component 40 includes a positioning member 41, which is movably disposed such that the positioning member 41 has a positioning position for pressing against one end of the rod 100 to be processed and a release position for separating from the rod 100 to be processed. The positioning member 41 has a positioning contact surface for contacting the rod 100 to be processed, and the limiting component 31 has a limiting wall 312 for limiting and engaging with the end of the rod 100 to be processed. The distance between the positioning contact surface and the plane where the receiving opening 111 is located is less than the distance between the limiting wall 312 and the plane where the receiving opening 111 is located.

[0057] In some embodiments, the positioning element 41 is movably disposed along a second direction.

[0058] In some embodiments, the positioning member 41 is rotatably disposed about a rotation axis extending along a third direction. This third direction is perpendicular to the second direction and perpendicular to the first direction.

[0059] Specifically, the limiting wall 312 can be the inner top surface of the limiting groove 310. The inner top surface of the limiting groove 310 is arranged opposite to the receiving opening 111. The distance between the positioning contact surface and the plane where the receiving opening 111 is located is less than the distance between the limiting wall 312 and the plane where the receiving opening 111 is located, so that the rod to be processed 100 is lower than the inner top surface of the limiting groove 310, thereby allowing the rod to be processed 100 to smoothly enter the limiting groove 310.

[0060] Please see Figure 2 By setting the positioning element 41, when the rod to be processed 100 is placed in the receiving cavity 110, the positioning element 41 first positions the rod to be processed 100 in the positioning position, and at the same time, the limiting component 30 is in the separation position, combined with Figure 4 It can be seen that after the positioning member 41 is in the positioning position, the control limiting member 31 moves from the separation position to the limiting position. During the movement of the limiting member 31, the limiting member 31 abuts against the positioning member 41 and drives the positioning member 41 to move from the positioning position to the release position. After the limiting member 31 is in the limiting position and the rod to be processed 100 is located in the limiting groove 310, the feeding drive member 12 drives the rod to be processed 100 to move to the position abutting against the limiting wall 312, so as to form a processing section with a preset length between the two clamping members 210 and the limiting member 31. Then, combined with Figure 5 It can be seen that the two clamping parts 210 clamp the rod to be processed 100 to fix the rod to be processed 100, and then, combined with Figure 6 It can be seen that when the limiting component 31 is disengaged, the machining mechanism processes the section of the rod 100 to be processed.

[0061] Because the positioning member 41 presses the rod to be processed 100 to a positioning position lower than the limiting wall 312 of the limiting groove 310, the limiting member 31 can smoothly enter the limiting groove 310. Since the positioning member 41 positions the rod to be processed 100 first, the limiting member 31 does not require the operator to manually press the rod to be processed 100 into a position that can enter the limiting groove 310 during the movement, which shortens the operator's operation time. In addition, the limiting member 31 is less likely to injure the operator during the movement, thereby improving the safety of the positioning fixture.

[0062] Please see Figure 1 and Figure 2 In some embodiments, the positioning component 40 includes a first mounting member 42 and a second elastic member 43. The first mounting member 42 has a first mounting cavity 420. The positioning member 41 passes through the first mounting cavity 420 and is movably disposed along a second direction. The first mounting cavity 420 has a first inner wall 421, which is located on the side of the first mounting cavity 420 away from the limiting member 31. The second elastic member 43 is sleeved on the positioning member 41. One end of the second elastic member 43 is connected to the positioning member 41, and the other end of the second elastic member 43 is connected to the first inner wall 421.

[0063] When the positioning member 41 is in the positioning position, the second elastic member 43 is in a free state. During the process of the positioning member 41 moving from the positioning position to the release position, the second elastic member 43 is in a compressed state. When it is necessary to reposition the rod to be processed 100, the elastic force of the second elastic member 43 drives the positioning member 41 to return from the release position to the positioning position. Compared with setting a driving power source (e.g., cylinder, hydraulic cylinder and electric push rod), the cost of setting a second elastic member 43 is lower.

[0064] In some embodiments, the positioning member 41 is a positioning rod, and the positioning rod is provided with a positioning protrusion 410. The second elastic member 43 is sleeved on the positioning rod and located between the positioning protrusion 410 and the first inner wall 421.

[0065] In some embodiments, the second elastic element 43 is a spring.

[0066] Please see Figure 2 and Figure 4In some embodiments, the two clamping members 210 include a first clamping member 211 and a second clamping member 212. The second clamping member 212 is disposed on the first clamping member 211 and movably disposed along a second direction. The first mounting member 42 is movably disposed along a first direction so that when the positioning member 41 is in the released position, the first mounting member 42 drives the positioning member 41 to move to the first clamping member 211, and the positioning member 41 and the second clamping member 212 are disposed opposite each other. The first mounting member 42 combined with the second elastic member 43 means that when the positioning member 41 is in the released position, the second elastic member 43 is in a compressed state, so that the elastic force of the second elastic member 43 causes the positioning member 41 to move toward the rod to be processed 100, and the rod to be processed 100 abuts against each other, so that the positioning member 41 can cooperate with a clamping member 210 to clamp the rod to be processed 100.

[0067] Specifically, the clamping member 210 closer to the first mounting member 42 is the first clamping member 211, and the other clamping member 210 is the second clamping member 212. The first clamping member 211 has a mounting groove, and a portion of the second clamping member 212 is disposed in the mounting groove and forms a clamping space 2101 with the mounting groove. The first clamping member 211 is provided with a clearance groove 2110 so that when the positioning member 41 and the first mounting member 42 move along the first direction to the first clamping member 211, they can pass the positioning member 41 through the clearance groove 2110.

[0068] In some embodiments, the first clamping member 211 has a first clamping contact surface for contacting the rod to be processed 100. The first clamping contact surface is provided with a plurality of anti-slip protrusions to increase the friction between the first clamping member 211 and the rod to be processed 100, thereby improving the situation where the rod to be processed 100 is easy to detach from the clamping space 2101.

[0069] In some embodiments, the second clamping member 212 has a second clamping contact surface for contacting the rod to be processed 100. The second clamping contact surface is provided with a plurality of anti-slip protrusions to increase the friction between the second clamping member 212 and the rod to be processed 100, thereby improving the situation where the rod to be processed 100 is easy to detach from the clamping space 2101.

[0070] In some embodiments, the plurality of anti-slip protrusions have a serrated structure.

[0071] In some embodiments, the first clamping contact surface is provided with an anti-slip pad made of a flexible material to protect the outer surface of the rod to be processed 100 and to improve the situation where the rod to be processed 100 is easy to detach from the clamping space 2101.

[0072] In some embodiments, the second clamping contact surface is provided with an anti-slip pad.

[0073] In some embodiments, the positioning member 41 has a columnar structure, and the shape of the clearance groove 2110 is adapted to the shape of the outer peripheral surface of the positioning member 41.

[0074] Specifically, the second clamping member 212 is movably arranged along the second direction. Combined with the movement of the first mounting member 42 and the arrangement of the second elastic member 43, when the positioning member 41 is in the release position, the rod to be processed 100 has a clamping force on both sides of the second direction toward the clamping space 2101, thereby improving the clamping stability of the rod to be processed 100.

[0075] Please see Figure 2 and Figure 4 In some embodiments, the positioning fixture further includes a support platform 50, and the first mounting member 42 is movably disposed on the support platform 50; the positioning assembly 40 includes a second mounting member 44 and a third elastic member 45, the second mounting member 44 is fixedly connected to the first mounting member 42 and is located on one side of the first mounting member 42 along a first direction; the third elastic member 45 is sleeved on the first mounting member 42, and the first mounting member 42 has a guiding effect on the third elastic member 45, one end of the third elastic member 45 is connected to the support platform 50, and the other end of the third elastic member 45 is connected to the second mounting member 44.

[0076] Combination Figure 5 It can be seen that by setting the third elastic element 45, when the positioning element 41 is in the positioning position, the third elastic element 45 is in the compressed state. When the positioning element 41 is in the released position, the third elastic element 45 returns from the compressed state to the free state, and drives the first mounting element 42 and the second mounting element 44 to move downward, so that the positioning element 41 moves to the position of abutting against the rod to be processed 100, so that the positioning element 41 and a clamping element 210 cooperate to clamp the rod to be processed 100. Compared with setting a driving power source (e.g., cylinder, hydraulic cylinder and electric push rod), the cost of setting the third elastic element 45 is lower.

[0077] Please see Figure 2 and Figure 4 In some embodiments, the second mounting member 44 has a second mounting cavity 440, and the support platform 50 has a groove 512. When the positioning member 41 is in the positioning position, the second mounting member 44 abuts against the support platform 50, and the third elastic member 45 is located in the second mounting cavity 440 and the groove 512 to hide the third elastic member 45.

[0078] Specifically, one end of the third elastic member 45 is fixedly connected to the inner wall of the end of the groove portion 512 away from the second mounting member 44, and the other end of the third elastic member 45 is fixedly connected to the inner wall of the second mounting cavity 440 away from the support platform 50.

[0079] Specifically, the first mounting member 42 includes a mounting rod, the second mounting member 44 includes a sleeve having a second mounting cavity 440, and the mounting rod and the sleeve are fixedly connected by screws / bolts.

[0080] In some embodiments, the third elastic element 45 is a spring.

[0081] Please see Figure 1 and Figure 2 In some embodiments, two clamping members 210 are mounted on the support platform 50; the receiving member 11 and the two clamping members 210 are respectively located on both sides of the support platform 50 in the thickness direction. The support platform 50 has a through hole 510 for the rod to be processed 100 to pass through. The through hole 510 communicates with the clamping space 2101 formed by the two clamping members 210. The receiving member 11 is fixedly connected to the support platform 50, and the receiving opening 111 of the receiving member 11 communicates with the through hole 510.

[0082] Specifically, the receiving component 11 is fixedly connected to the support platform 50 by screws / bolts.

[0083] Please see Figure 1 and Figure 2 In some embodiments, multiple rods 100 to be processed are provided, and multiple feeding components 10 and clamping components 20 are also provided. The multiple feeding components 10 are spaced apart along a third direction, and a clamping component 20 is correspondingly provided at the receiving opening 111 of the receiving part 11 of each feeding component 10; wherein, the third direction is perpendicular to the first direction and the second direction; the limiting member 31 is a limiting rod, and multiple limiting grooves 310 and limiting openings 311 are provided. The multiple limiting grooves 310 and limiting openings 311 are provided in a one-to-one correspondence. The multiple limiting grooves 310 are spaced apart along the length of the limiting rod, and each limiting groove 310 is used to limit the rod 100 to be processed on a clamping component 20.

[0084] Existing machining rods are generally placed horizontally on the positioning fixture, and their length typically extends along a third direction, which occupies a significant area of ​​the positioning fixture. In this application, because the length of the machining rod 100 extends along a first direction, it is placed vertically, thereby reducing the area occupied by the machining rod 100 on the positioning fixture. This allows for the placement of a larger number of machining rods 100, enabling the machining mechanism to process more rods 100 simultaneously and improving processing efficiency. Specifically, the support table 50 has a support surface; if the machining rod is placed horizontally on the positioning fixture, it will occupy a significant area of ​​the support surface.

[0085] In this application, please refer to Figure 1 and Figure 7In this application, the rod to be processed 100 is placed vertically, allowing it to pass through the through hole 510 of the support table 50. This reduces the area occupied by the rod to be processed 100 on the support table 50. Furthermore, when the rod to be processed 100 is finally processed, the clamping assembly 20 clamps it at one end along its length, thus reducing material waste. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 In some embodiments, the multiple clamping components 20 are divided into multiple first clamping components 21 and multiple second clamping components 22. The first clamping components 21 and the second clamping components 22 are distributed along a second direction. The multiple first clamping components 21 are spaced apart along a third direction, and the multiple second clamping components 22 are spaced apart along a third direction. Two limiting rods (limiting members 31) are provided. Multiple limiting grooves 310 of one limiting rod are used to limit and cooperate with the rods 100 to be processed on the multiple first clamping components 21, and multiple limiting grooves 310 of the other limiting rod are used to limit and cooperate with the rods 100 to be processed on the multiple second clamping components 22. By arranging the multiple clamping components 20 in two rows, since each clamping component 20 is provided with a corresponding receiving member 11, the number of rods 100 to be processed that can be accommodated is further increased, the processing efficiency of the processing equipment is improved, and the structural distribution of the multiple clamping components 20 is made more reasonable.

[0086] Please see Figure 1 and Figure 2 In some embodiments, the plurality of first clamping components 21 and the plurality of second clamping components 22 each include a first clamping member 211 and a second clamping member 212. The first clamping member 211 of the plurality of first clamping components 21 is an integral structure, and the first clamping member 211 of the plurality of second clamping components 22 is an integral structure. It can be understood that a first clamping member 211 is provided with a plurality of mounting slots, and each mounting slot is provided with a second clamping member 212 of a clamping component. The plurality of mounting slots of a first clamping member 211 are formed by stamping or cutting.

[0087] In some embodiments, the first clamping member 211 is fixedly connected to the support platform 50; specifically, the first clamping member 211 is fixedly connected to the support platform 50 by screws / bolts.

[0088] Please see Figure 1 and Figure 8 In some embodiments, the limiting component 30 further includes a limiting drive structure 32, which is connected to the limiting member 31 to drive the limiting member 31 to move. By setting the limiting drive structure 32, the automatic movement of the limiting member 31 is realized, improving the automation level of the positioning fixture 1.

[0089] Please see Figure 1 and Figure 8In some embodiments, the limiting drive structure 32 includes a limiting drive member 320 and two connecting rods 321. The limiting drive member 320 is disposed on the side of the limiting member 31 near the receiving component 11. Each of the two connecting rods 321 has a first end 3211 and a second end 3212. The first ends 3211 of the two connecting rods 321 are hinged, and the second ends 3212 of the two connecting rods 321 are respectively connected to two limiting rods. The limiting drive member 320 is connected to the first ends 3211 of the two connecting rods 321 to drive the first ends 3211 of the two connecting rods 321 to move along a first direction, thereby causing the second ends 3212 of the two connecting rods 321 to move relatively closer or further away along a second direction. By setting two connecting rods 321, only one limiting drive member 320 is needed to realize the movement of the two limiting members 31. Compared with setting two limiting drive members to drive the movement of the two limiting members 31 separately, this simplifies the structure of the limiting assembly 30 and saves costs.

[0090] In some embodiments, the limiting drive 320 is a piston cylinder; optionally, the piston cylinder is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0091] Please see Figure 1 and Figure 8 In some embodiments, the limiting component 30 further includes a limiting slider 33 and a limiting guide rail 34. The limiting guide rail 34 is disposed on the support platform 50. The limiting slider 33 is slidably connected to the limiting guide rail 34. The limiting slider 33 is fixedly connected to the limiting rod (limiting member 31) so that the limiting rod can move smoothly through the cooperation of the limiting slider 33 and the limiting guide rail 34, and play a guiding role in the movement of the limiting rod.

[0092] In some embodiments, two limit sliders 33 and two limit guide rails 34 are provided, with the two limit sliders 33 and the two limit guide rails 34 being provided in a one-to-one correspondence, and the two limit sliders 33 being connected to the two ends of the limit rod in the length direction respectively.

[0093] Specifically, multiple clamping components 20 are located between two limiting guide rails 34.

[0094] Please see Figure 2 and Figure 4 In some embodiments, the clamping assembly 20 includes a clamping drive structure 23 connected to a clamping member 210 to drive the clamping member 210 to move along a second direction. By setting the clamping drive structure 23, automatic movement of the clamping member 210 is achieved, improving the automation level of the positioning fixture 1.

[0095] In some embodiments, the plurality of clamping components 20 are divided into a plurality of first clamping components 21 and a plurality of second clamping components 22. A plurality of clamping drive structures 23 are provided, each clamping drive structure 23 being disposed between a first clamping component 21 and a second clamping component 22. Each clamping drive structure 23 includes a clamping drive member 230, a first slider 231, and two second sliders 232. The clamping drive member 230 is disposed on the side of the clamping member 210 near the receiving member 11. The clamping drive member 230 is connected to the first slider 231, which has a first contact surface 2311 and a second contact surface 2312. Along the direction near the clamping member 210... The distance between the first contact surface 2311 and the second contact surface 2312 gradually decreases; one second slider 232 is connected to a clamping member 210 of the first clamping assembly 21, and the other second slider 232 is connected to a clamping member 210 of the second clamping assembly 22. Both second sliders 232 have a third contact surface 2320. Along the direction close to the clamping member 210, the distance between the third contact surfaces 2320 of the two second sliders 232 gradually decreases; the third contact surface 2320 of one second slider 232 contacts the first contact surface 2311, and the third contact surface 2320 of the other second slider 232 contacts the second contact surface 2312.

[0096] By using the above-described cooperation between the first slider 231 and the two second sliders 232, only one clamping drive member 230 is needed to enable the movement of the clamping member 210 of the first clamping assembly 21 and the clamping member of the second clamping assembly 22 along the second direction. Compared to setting two clamping drive members to drive the movement of the clamping member 210 of the first clamping assembly 21 and the clamping member 210 of the second clamping assembly 22 respectively, the structure of the clamping assembly 20 is simplified and the cost is saved.

[0097] In some embodiments, the clamping drive 230 is a piston cylinder; alternatively, the piston cylinder is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0098] Specifically, of the two second sliders 232, one second slider 232 is connected to the second clamping member 212 of the first clamping assembly 21, and the other second slider 232 is connected to the second clamping member 212 of the second clamping assembly 22.

[0099] Specifically, the support platform 50 is provided with a plurality of clearance holes 511, and the plurality of clearance holes 511 are provided in a one-to-one correspondence with a plurality of clamping drive structures 23. Each clearance hole 511 is used to avoid the first slider 231 and two second sliders 232 of a clamping drive structure 23.

[0100] In some embodiments, the positioning fixture further includes a baffle plate 60, which covers the second clamping member 212 of the clamping assembly 20 (on the side of the support platform 50 away from the receiving member 11).

[0101] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
