Description
Technical Field
[0001] The present invention belongs to the technical field of cup manufacturing, and in particular relates to a rapidly deployed material transfer and conveying system between workstations and a deployment method thereof. Background Art
[0002] During the production process of thermos cups, the thermos cups need to go through a series of processes such as laser cutting, shrinking, laser head cutting, stretching the cup body, shaping, thread pressing, and flat mouth and flat bottom. After the cup body and cup lid of the thermos cup are produced, they need to be assembled, including polishing and cleaning the cup mouth, surface decorative sheets, placing instructions and combining the cup lid and cup body. At present, the entire processing process generally uses separate processing equipment or integrated automatic production lines, but the current production lines all use packaged customized production design, and the positional relationship and distance between each process are precisely designed. After the processing equipment is completed, the factory deployment and installation need to be completed by a professional team, and due to the setting of the precise positional relationship between the processing equipment during deployment, more refined deployment is also required, which takes a long time. Summary of the invention
[0003] The purpose of the present invention is to provide a quickly deployed material transfer and conveying system between workstations and a deployment method thereof in response to the above-mentioned technical problems, so as to place the adjustment accuracy requirements on components that are relatively easy to control, save the deployment time of the system, and ensure the smooth processing and production of workpieces.
[0004] In view of this, the present invention provides a method for deploying a material flow conveying system between various workstations for rapid deployment, comprising the following steps:
[0005] S1: Deploy the processing equipment at each station, and place the processing equipment corresponding to each station of the thermos cup production in a linear manner. Install a gripping component capable of rotating and grabbing the workpiece on both sides of each processing equipment at each station. The rotation radius of the gripping component is R. When deployed, the spacing distance between the gripping components on the adjacent sides of the adjacent processing equipment at two adjacent stations is H, and the spacing distance H can be any value within the standard range;
[0006] S2: Find the midpoint and deploy the transfer assembly, use the measuring and marking tool to measure the spacing H between the grab assemblies on the adjacent sides of the two adjacent processing equipment and mark the midpoint line between the two grab assemblies, and deploy the transfer assembly for the rotary flow workpiece at the midpoint;
[0007] S3: Symmetrically adjust the position of the positioning fixture, calculate the compensation distance D=H-2*R, adjust the distance D by the fine-tuning tool, and use the adjusted fine-tuning tool as a standard tool to adjust the distance d of the two positioning fixtures of the transfer assembly, so that the two positioning fixtures move symmetrically with the midpoint line between the two adjacent process processing equipment, that is, the midline of the transfer assembly as the symmetry axis until the value of d reaches D;
[0008] S4: Repeat steps S2-S3 until the transfer components are deployed and adjusted between all workstations.
[0009] In the present technical scheme, since the mass and volume of each processing equipment are large, it is difficult to deploy them, especially the position adjustment. If you want to adjust to a very precise position, it will take a long time, and the position of the grabbing component of each processing setting is also different. When the processing equipment of each station is deployed using this method, the distance between the two adjacent stations does not need to be too precise. The processing equipment of each station can be aligned within the error range within the standard range, and then the transfer component with smaller mass and volume and easier to control is accurately placed in the middle position between the two adjacent stations. Finally, the position of the two positioning tooling on the transfer component is fine-tuned by the fine-tuning tool so that the grabbing component just rotates to the positioning tooling when it rotates, which is convenient for grabbing parts. This method can roughly deploy large-volume equipment and accurately deploy small-volume transfer components, and the adjustment accuracy requirements are placed on components that are easier to control, which can save system deployment time.
[0010] Furthermore, the standard range of the spacing distance H in S1 is dmin+2*R≤H≤d max +2*R.
[0011] Furthermore, after the S3 positioning tool is adjusted into place, the flexible mode of the positioning tool is turned on, and the positioning tool is switched from a radially fixed state to a state with radial movable space to compensate for the size and shape and position errors of the workpiece and the errors when deploying the transfer component position.
[0012] In this technical solution, the positioning tooling is radially limited during deployment. After the positioning tooling is deployed, it is switched to flexible mode so that the positioning tooling has a slight radial movement space. This can compensate for the size and shape and position errors of the workpiece and the errors in the position of the transfer component during deployment, thereby ensuring smooth processing and production of the workpiece.
[0013] Furthermore, the rapidly deployed material transfer and conveying system between workstations includes:
[0014] A transfer assembly is provided at the midpoint between two adjacent workstations, and the transfer assembly includes a base, a swivel seat capable of circumferential rotation is provided on the base, and two positioning fixtures are symmetrically provided on the swivel seat about the rotation center, and the positioning fixtures are used to receive the workpiece;
[0015] A grabbing assembly, one grabbing assembly is symmetrically arranged on both sides of the processing point of the processing equipment at each station, and the grabbing assembly is used to rotate between the processing point of the processing equipment and the positioning tooling of the transfer assembly to pick up and place the workpiece;
[0016] A fine-tuning tool is used to adjust the distance between two positioning fixtures on the transfer component so that the two positioning fixtures are respectively located on the rotation paths of the grabbing components on both sides.
[0017] In the present technical scheme, the workpiece processed at the processing point of the processing equipment of the previous process is rotated and grasped by the grasping component close to the next transfer component and placed on the proximal positioning tooling of the next transfer component. At the same time, the workpiece of another positioning tooling on the transfer component is rotated and grasped by the grasping component on the next processing equipment to the processing point for processing. During the workpiece processing, the transfer component itself rotates, so that the workpiece just grasped to the proximal positioning tooling is rotated to the side close to the next station processing equipment, so as to be grasped and processed next time.
[0018] Furthermore, a rotary cylinder is arranged on the top of the base of the transfer assembly, and the rotary seat is connected to the output end of the rotary cylinder and can rotate circumferentially. Two sliding seats are symmetrically slidably arranged on the rotary seat about the rotation center. The sliding seat and the rotary seat can be fixedly connected by a fixed structure. The two positioning tools mentioned above are respectively arranged on the two sliding seats and can move synchronously with the sliding seats.
[0019] Further, the fine-tuning tool includes:
[0020] Fine-tuning rods, wherein four fine-tuning rods are provided, and the four fine-tuning rods are hingedly connected to each other end to end to form a diamond structure;
[0021] Cover, the cover has two covers respectively arranged on a set of diagonal portions of the diamond structure and connected to corresponding fine-tuning rods, and the inner cavity shape of the cover matches the outer shape of the positioning tooling;
[0022] A centering rod, both ends of which are fixedly connected to the midpoints of a group of opposite sides of the diamond structure, a centering shaft is vertically connected to the midpoint of the centering rod, a center hole is opened on the rotation center of the swivel seat, and the centering shaft matches the shape and size of the center hole and can be inserted into the center hole.
[0023] The two fine-tuning rods hinged to each other can be fixed by a screw connection structure.
[0024] Furthermore, the fixing structure includes:
[0025] A threaded hole, wherein the threaded hole is provided on the swivel seat;
[0026] A slide groove, which is arranged on the sliding seat and is connected with the threaded hole;
[0027] The fastening bolt can pass through the slide groove and connect with the threaded hole to fix the sliding seat on the swivel seat.
[0028] In the present technical solution, when the D value is calculated according to the formula D=H-2*R, the screw structure on the fine-tuning rod is loosened so that the diamond structure can change its shape freely, the diamond structure is adjusted so that the center distance between the two covers is equal to the D value, and then the screw structure is tightened to lock the diamond structure. At this time, the fine-tuning tool has been adjusted into place, the centering shaft is inserted into the center hole on the swivel seat, and then the sliding seat is moved so that the positioning tool on the sliding seat can be covered by the cover. At this time, it indicates that the position of the positioning tool has been adjusted into place, and then the sliding seat is fixed by the fixed structure.
[0029] Furthermore, the grabbing component comprises:
[0030] A grab seat, the grab seat is connected to the lifting assembly and can be lifted and lowered in the vertical direction, and a rotary motor is fixedly connected to the grab seat;
[0031] A grabbing arm, one end of which is connected to the output end of the rotary motor, and the other end of which is fixedly connected to a clamping claw assembly.
[0032] Furthermore, a convex ring is extended outward from the bottom of the positioning tool, a switching rod is coaxially arranged at the center of the convex ring, two arc-shaped blocks are arranged on the outer periphery of the lower end of the switching rod, a convex column is extended upward from the surface of the sliding seat, a flexible adjustment member is fixedly sleeved on the outer periphery of the convex column, and the flexible adjustment member includes a retaining frame and a steel ball, a plurality of spherical holes matching the shape of the steel ball are opened on the peripheral wall of the retaining frame, a positioning pin is arranged in the spherical hole parallel to the axis of the retaining frame, an adjustment hole is provided through the steel ball, the steel ball is sleeved on the outer periphery of the positioning pin through the adjustment hole, a displacement gap is provided between the adjustment hole and the positioning pin for the steel ball to move, a switching hole coaxial with the convex column is opened in the sliding seat, and the switch hole The switching rod sleeve is arranged in the switching hole, the switching hole diameter is larger than the switching rod outer diameter, and two oppositely arranged first arc blocks and two oppositely arranged second arc blocks are protruding on the inner wall of the switching hole in the axial direction. The inner diameters of the first arc block and the second arc block are smaller than the inner diameter of the switching hole. The first arc block and the second arc block are arranged up and down along the axial direction and are close to each other. The inner diameter of the first arc block is larger than the inner diameter of the second arc block, and the difference between the inner diameters of the first arc block and the second arc block is larger than the displacement gap of the steel ball movement. The inner diameter of the first arc block matches the outer diameter of the arc block on the switching rod, and switching channels that allow the arc blocks to slide up and down are formed between the two first arc blocks and the two second arc blocks.
[0033] In the present technical solution, during the deployment process, since the transfer assembly is deployed separately, the overall position of the transfer assembly will more or less and inevitably have slight deviations in the front, back, left and right directions, and there are also size and roundness deviations between the cups, as well as coaxiality deviations between the inner and outer walls. The current common means is to increase the positioning gap between the inner wall of the cup and the positioning tooling. As long as the positioning gap is large enough, the cup can still be easily positioned on the tooling of the transfer assembly, and the reserved gap is usually 3-4mm. However, a large positioning gap will cause the inner wall of the cup to collide violently with the outer wall of the positioning tooling when the transfer assembly rotates circumferentially, and such collisions occur multiple times, and collisions will occur repeatedly during the transfer flow between each process. Multiple collisions will cause the cup to bump or even deform, affecting the processing quality and processing progress. Therefore, it is necessary to adopt the method of reducing the positioning gap and reducing the movement and shaking of the cup when the transfer component rotates circumferentially, so as to reduce the collision intensity. However, this will be affected by the slight deviations of the front, back, left and right sides of the transfer component when it is installed. Problems such as the size and roundness deviation between the cups and the coaxiality deviation of the inner and outer walls will be exposed, making it more difficult to place the cup on the positioning tooling.
[0034] When the fine-tuning tool adjusts the position of the positioning tool, the positioning tool is radially fixedly set on the sliding seat, and the two arc blocks are matched with the inner diameter of the first arc block so that the positioning tool and the sliding seat can be adjusted synchronously. This is to ensure that the fine-tuning tool adjusts the position of the positioning tool accurately. When the position adjustment of the positioning tool is completed, the workpiece can be produced. The radially fixed state of the positioning tool is switched to a state with a small radial moving space, and the machine is switched to a flexible mode to compensate for the size and shape errors of the workpiece and the errors when deploying the transfer component. It is only necessary to rotate the positioning tool half a circle on the axis to align the arc block with the switching channel, and then push the positioning tool downward until the lower end of the arc block contacts the surface of the sliding seat, and then reverse the positioning tool half a circle to reset the positioning tool circumferentially. At this time, the upper end of the arc block is attached to the lower end of the second arc block. At this time, the axial direction of the positioning tool is limited and fixed, and it can only move in the radial direction within the displacement gap range of the steel ball. The positioning fixture always maintains this flexible mode state during the production process of the production line, that is, it allows a slight displacement in the circumferential direction. When the cup is gradually put on the outside of the positioning fixture, the positioning fixture is allowed to move slightly for self-adjustment, that is, the positioning gap is divided into two parts, namely the fixed gap between the inner wall of the cup and the outer wall of the positioning fixture, and the adjustment gap between the positioning fixture and the sliding seat. The fixed gap is mainly aimed at the size and roundness deviation between each cup and the coaxiality deviation of the inner and outer walls. The adjustment gap is mainly aimed at the slight deviation of the front, back, left and right when the transfer component is installed, so that the collision potential energy is decomposed into two parts, namely the collision between the positioning fixture and the cup during transfer and the collision between the steel ball and the inner wall of the arc block of the positioning fixture, thereby reducing the intensity of the cup being hit and ensuring the efficiency of the cup being placed on the positioning fixture. The use of the retainer and steel ball is a flexible mode that only requires the movement of the steel ball to self-adjust and is smoother.
[0035] Furthermore, the gap between the inner wall of the cup and the outer wall of the positioning fixture is 1.5 mm, and the displacement gap of the steel ball movement is 1 mm.
[0036] In this technical solution, a flexible mode structure is adopted, and an overall gap of 2.5 mm can meet the efficiency requirements of placing the cup on the positioning tooling, which is smaller than the original conventional 3-4 mm, and the overall gap of 2.5 mm is also dispersed in two places.
[0037] The beneficial effects of the present invention are:
[0038] 1. When this method is used to deploy the processing equipment at each station, the distance between the two adjacent stations does not need to be too precise. The processing equipment at each station can be aligned within the error range within the standard range, and then the transfer component with smaller mass and volume that is easier to control is accurately placed in the middle position between the two adjacent stations. Finally, the position of the two positioning tooling on the transfer component is fine-tuned by the fine-tuning tool so that the grasping component rotates just to the positioning tooling when it rotates, which is convenient for grasping parts. This method can be used to roughly deploy large-volume equipment and accurately deploy small-volume transfer components, and the adjustment accuracy requirements are placed on components that are easier to control, which can save system deployment time.
[0039] 2. The positioning tool is radially limited during deployment. After the positioning tool is deployed, it is switched to flexible mode so that the positioning tool has a slight radial movement space. This can compensate for the size and shape errors of the workpiece and the errors in the position of the transfer component during deployment, ensuring the smooth processing and production of the workpiece.
[0040] 3. The positioning gap is divided into two parts, namely the fixed gap between the inner wall of the cup and the outer wall of the positioning fixture, and the adjustable gap between the positioning fixture and the sliding seat. The fixed gap is mainly aimed at the size and roundness deviation between the cups and the coaxiality deviation of the inner and outer walls, etc. The adjustable gap is mainly aimed at the slight deviations of the front, back, left and right when the transfer component is installed, so that the collision potential energy is decomposed into two parts, namely the collision between the positioning fixture and the cup during transfer and the collision between the steel ball and the inner wall of the arc block of the positioning fixture, thereby reducing the intensity of the cup being hit and ensuring the efficiency of the cup being placed on the positioning fixture. The use of the retainer and steel ball is a flexible mode that only requires the movement of the steel ball to self-adjust and is smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Embodiment 1
[0064] like Figure 1-2 As shown, a method for deploying a material flow conveying system between various workstations for rapid deployment includes the following steps:
[0065] S1: deploy processing equipment 1 at each station, and place the processing equipment 1 corresponding to each station of the thermos cup production in a linear manner at intervals. A gripping component 2 capable of rotating and grabbing the workpiece is installed on both sides of each processing equipment 1 at the station. The rotation radius of the gripping component 2 is R. When deployed, the spacing distance between the gripping components 2 on the adjacent sides of the adjacent processing equipment 1 at two adjacent stations is H, and the spacing distance H can be any value within the standard range;
[0066] S2: Find the midpoint and deploy the transfer component 3, use the measuring and marking tool to measure the spacing H between the grabbing components 2 on the adjacent sides of the two adjacent processing equipment 1, mark the midpoint line between the two grabbing components 2, and deploy the transfer component 3 for the rotary flow workpiece at the midpoint;
[0067] S3: Symmetrically adjust the position of the positioning fixture 4, calculate the compensation distance D = H-2*R, adjust the distance of length D through the fine-tuning tool 5, and use the adjusted fine-tuning tool 5 as a standard tool to adjust the distance d of the two positioning fixtures 4 of the transfer component 3, so that the two positioning fixtures 4 move symmetrically with the midpoint line between the two adjacent process processing equipment 1, that is, the midline of the transfer component 3 as the symmetry axis until the value of d reaches D; the standard range of the interval distance H in S1 is dmin+2*R≤H≤d max +2*R.
[0068] S4: Repeat steps S2-S3 until the transfer components 3 are deployed and adjusted between all workstations.
[0069] Because the mass and volume of each processing equipment 1 are large, it is difficult to deploy them, especially the position adjustment. It takes a long time to adjust to a very precise position, and the position of the grabbing component 2 of each processing setting is also different. When the processing equipment 1 of each station is deployed using this method, the distance between the two adjacent stations does not need to be too precise. The processing equipment 1 of each station can be aligned within the error range within the standard range, and then the transfer component 3 with a smaller mass and volume and easier to control is accurately placed in the middle position between the two adjacent stations. Finally, the position of the two positioning fixtures 4 on the transfer component 3 is fine-tuned by the fine-tuning tool 5 so that the grabbing component 2 rotates just to the positioning fixture 4 when it rotates, which is convenient for grabbing parts. This method can roughly deploy large-volume equipment and accurately deploy small-volume transfer components 3, placing the adjustment accuracy requirements on components that are easier to control, which can save system deployment time. In addition, the positioning fixture 4 is radially fixed during deployment.
[0070] After the positioning fixture 4 is adjusted in place at S3, the flexible mode of the positioning fixture 4 is turned on, and the positioning fixture 4 is switched from a radially fixed state to a radially movable state to compensate for the size and shape errors of the workpiece and the errors when the transfer component 3 is deployed. After the positioning fixture 4 is deployed, it is switched to the flexible mode, so that the positioning fixture 4 has a slight radial movable space, which can compensate for the size and shape errors of the workpiece and the errors when the transfer component 3 is deployed, and ensure the smooth processing and production of the workpiece.
[0071] Embodiment 2
[0072] like Figure 2-8 As shown, the rapidly deployed material transfer and conveying system between workstations includes a transfer component 3, a gripping component 2 and a fine-tuning tool 5.
[0073] A transfer assembly 3 is provided at the midpoint between two adjacent workstations. The transfer assembly 3 includes a base 6, on which a swivel seat 7 capable of circumferential rotation is provided. Two positioning fixtures 4 are symmetrically provided on the swivel seat 7 about the center of rotation, and the positioning fixtures 4 are used to receive the workpiece; a rotary cylinder 8 is provided on the top of the base 6 of the transfer assembly 3, and the swivel seat 7 is connected to the output end of the rotary cylinder 8 and can rotate circumferentially, and two sliding seats 9 are symmetrically provided about the center of rotation on the swivel seat 7, and the sliding seat 9 can be fixedly connected to the swivel seat 7 through a fixed structure, and the two positioning fixtures 4 are respectively provided on the two sliding seats 9 and can move synchronously with the sliding seat 9. The fixed structure includes a threaded hole 10, a slide groove 11 and a fastening bolt. The threaded hole 10 is provided on the swivel seat 7; the slide groove 11 is provided on the sliding seat 9, and the slide groove 11 is connected to the threaded hole 10; the fastening bolt can pass through the slide groove 11 and connect with the threaded hole 10 to fix the sliding seat 9 on the swivel seat 7.
[0074] A grab assembly 2 is symmetrically arranged on both sides of the processing point of the processing equipment 1 on each workstation, and the grab assembly 2 is used to rotate between the processing point of the processing equipment 1 and the positioning fixture 4 of the transfer assembly 3 to pick up and place the workpiece; the grab assembly 2 includes a grab seat 12 and a grab arm 13. The grab seat 12 is connected to the lifting assembly 14 and can be lifted and lowered in the vertical direction. A rotary motor 15 is fixedly connected to the grab seat 12; one end of the grab arm 13 is connected to the output end of the rotary motor 15, and the other end is fixedly connected to the clamping claw assembly 16.
[0075] The workpiece processed at the processing point of the processing equipment 1 of the previous process is rotated and grasped by the grasping component 2 close to the side of the next transfer component 3 and placed on the proximal positioning tooling 4 of the next transfer component 3. At the same time, the workpiece of another positioning tooling 4 on the transfer component 3 is rotated and grasped by the grasping component 2 on the next processing equipment 1 to the processing point for processing. During the workpiece processing, the transfer component 3 itself rotates, so that the workpiece just grasped to the proximal positioning tooling 4 is rotated to the side close to the next station processing equipment 1, so as to be grasped and processed next time.
[0076] The fine-tuning tool 5 is used to adjust the distance between the two positioning fixtures 4 on the transfer assembly 3 so that the two positioning fixtures 4 are respectively located on the rotation path of the grabbing assemblies 2 on both sides. The fine-tuning tool 5 includes a fine-tuning rod 17, a cover 18 and a centering rod 19. There are four fine-tuning rods 17, and the four fine-tuning rods 17 are hingedly connected to each other at the head and tail to form a diamond structure; there are two covers 18, which are respectively arranged on a set of diagonal angles of the diamond structure and connected to the corresponding fine-tuning rods 17, and the inner cavity shape of the cover 18 matches the external shape of the positioning fixture 4; the two ends of the centering rod 19 are respectively fixedly connected to the midpoints of a set of opposite sides of the diamond structure, and the midpoint of the centering rod 19 is vertically connected with a centering shaft 20, and a center hole 21 is opened on the rotation center of the swivel seat 7. The centering shaft 20 matches the shape and size of the center hole 21 and can be inserted into the center hole 21, and the two hinged fine-tuning rods 17 can be fixed by a screw structure.
[0077] When the D value is calculated according to the formula D=H-2*R, loosen the screw structure on the fine-tuning rod 17 so that the diamond structure can change its shape freely, adjust the diamond structure so that the center distance between the two covers 18 is equal to the D value, and then tighten the screw structure to lock the diamond structure. At this time, the fine-tuning tool 5 has been adjusted into place, insert the centering shaft 20 into the center hole 21 on the swivel seat 7, and then move the sliding seat 9 so that the positioning tool 4 on the sliding seat 9 can be covered by the cover 18. At this time, it means that the position of the positioning tool 4 has been adjusted into place, and then fix the sliding seat 9 through the fixed structure.
[0078] Embodiment 3
[0079] During the deployment process, because the transfer component 3 is deployed separately, the overall position of the transfer component 3 will more or less and inevitably have slight deviations in the front, back, left and right directions, and there are also size and roundness deviations between the cups, as well as coaxiality deviations between the inner and outer walls. The current common means is to increase the positioning gap between the inner wall of the cup and the positioning tooling 4. As long as the positioning gap is large enough, the cup can still be easily positioned on the tooling of the transfer component 3, and the reserved gap is usually 3-4mm. However, a large positioning gap will cause the inner wall of the cup to collide violently with the outer wall of the positioning tooling 4 when the transfer component 3 rotates circumferentially, and such collisions are multiple, and collisions will occur repeatedly during the transfer flow between each process. Multiple collisions will cause the cup to bump or even deform, affecting the processing quality and processing progress. Therefore, it is necessary to adopt a method of reducing the positioning gap to reduce the movement and shaking of the cup when the transfer component 3 rotates circumferentially, so as to reduce the collision intensity. However, this will be affected by slight deviations in the front, back, left and right directions of the transfer component 3 when it is installed, and problems such as size and roundness deviations between the cups and coaxiality deviations between the inner and outer walls will be exposed, making it more difficult to place the cup on the positioning tooling 4.
[0080] Now set up as Figure 9-15 In the structure shown, a convex ring 22 extends outward from the bottom of the positioning tool 4, a switching rod 23 is coaxially arranged at the center of the convex ring 22, two arc-shaped blocks 24 are arranged on the outer periphery of the lower end of the switching rod 23, a convex column 25 is extended upward from the surface of the sliding seat 9, a flexible adjustment member 26 is fixedly sleeved on the outer periphery of the convex column 25, the flexible adjustment member 26 includes a retaining frame 27 and a steel ball 28, a plurality of spherical holes 29 matching the shape of the steel ball 28 are opened on the peripheral wall of the retaining frame 27, a positioning pin 30 is arranged in the spherical hole 29 parallel to the axis of the retaining frame 27, an adjustment hole 31 is set through the steel ball 28, the steel ball 28 is sleeved on the outer periphery of the positioning pin 30 through the adjustment hole 31, and a displacement gap 32 for the steel ball 28 to move is provided between the adjustment hole 31 and the positioning pin 30, and a switching hole 32 coaxial with the convex column 25 is opened in the sliding seat 9 The switch rod 23 is sleeved in the switch hole 33. The diameter of the switch hole 33 is larger than the outer diameter of the switch rod 23. Two first arc blocks 34 and two second arc blocks 35 are arranged opposite to each other on the inner wall of the switch hole 33 protruding toward the axial direction. The inner diameters of the first arc block 34 and the second arc block 35 are both smaller than the inner diameter of the switch hole 33. The first arc block 34 and the second arc block 35 are arranged up and down along the axial direction and are close to each other. The inner diameter of the first arc block 34 is larger than the inner diameter of the second arc block 35, and the difference between the inner diameter of the first arc block 34 and the inner diameter of the second arc block 35 is larger than the displacement gap 32 for the movement of the steel ball 28. The inner diameter of the first arc block 34 matches the outer diameter of the arc block 24 on the switch rod 23. A switching channel 36 is formed between the two first arc blocks 34 and the two second arc blocks 35 to allow the arc block 24 to slide up and down. The gap between the inner wall of the cup and the outer wall of the positioning tool 4 is 1.5mm, and the displacement gap 32 for the movement of the steel ball 28 is 1mm.
[0081] When the fine adjustment tool 5 adjusts the position of the positioning fixture 4, the positioning fixture 4 is radially fixedly arranged on the sliding seat 9. Fig.11 As shown, the two arc blocks 24 are arranged to match the inner diameter of the first arc block 34 so that the positioning fixture 4 and the sliding seat 9 can be adjusted synchronously. This is to fine-tune the tool 5 to adjust the position of the positioning fixture 4 accurately. When the position adjustment of the positioning fixture 4 is completed, the production of the workpiece can be started. The radially fixed state of the positioning fixture 4 is switched to a state with a small radial moving space, and the machine is switched to a flexible mode to compensate for the size and shape and position errors of the workpiece and the errors when the transfer component 3 is deployed. It is only necessary to rotate the positioning fixture 4 half a circle on the axis to align the arc block 24 with the switching channel 36, and then push the positioning fixture 4 downward until the lower end of the arc block 24 contacts the surface of the sliding seat 9, and then reverse the positioning fixture 4 half a circle to reset the positioning fixture 4 circumferentially. At this time, the upper end of the arc block 24 is in contact with the lower end of the second arc block 35. At this time, the axial direction of the positioning fixture 4 is limited and fixed, and it can only move in the radial direction within the displacement gap 32 of the steel ball 28. At this time, Fig.12 As shown. The positioning fixture 4 always maintains this flexible mode state during the production process of the production line, that is, a slight displacement is allowed in the circumferential direction. When the cup is gradually put on the outside of the positioning fixture 4, the positioning fixture 4 is allowed to move slightly for self-adjustment, that is, the positioning gap is divided into two parts, namely, the fixed gap between the inner wall of the cup and the outer wall of the positioning fixture 4 and the adjustment gap between the positioning fixture 4 and the sliding seat 9. The fixed gap is mainly aimed at the size and roundness deviation between each cup and the coaxiality deviation of the inner and outer walls, etc. The adjustment gap is mainly aimed at the slight deviation of the front, back, left and right when the transfer component 3 is installed, so that the collision potential energy is decomposed into two parts, namely, the collision between the positioning fixture 4 and the cup during transfer and the collision between the steel ball 28 and the inner wall of the arc block 24 of the positioning fixture 4, thereby reducing the intensity of the cup being hit and ensuring the efficiency of the cup being placed on the positioning fixture 4. The form of the retainer 27 and the steel ball 28 is a flexible mode that only requires the movement of the steel ball 28 to self-adjust and is smoother. With the flexible mode structure, the overall gap of 2.5 mm can meet the efficiency requirement of placing the cup on the positioning fixture 4, which is smaller than the original conventional 3-4 mm, and the overall gap of 2.5 mm is also dispersed in two places.
