Description

Technical Field

[0001] The present application relates to the technical field of positioning fixtures, and in particular to a positioning fixture for production and processing. Background Art

[0002] Positioning fixtures refer to structures that fix the processed parts on the processing table to limit the movement of the processed parts, thereby facilitating the processing of the processed parts. For example, on a body parts processing production line, when body parts need to be welded, the body parts need to be relatively fixed on the welding table to facilitate the welding gun to perform precise welding processing on the welding position.

[0003] There are many ways for traditional positioning tooling to fix the processed parts, such as bolt clamping, clamping with a pressure plate against the processed parts, etc. However, the aforementioned clamping and positioning methods generally require adjustment of the relative positions of the bolts and the processing table, and the pressure plate and the processing table to achieve replacement of the processed parts and positioning of batches of processed parts. The aforementioned adjustment methods generally rely on manual adjustment, which increases the replacement time of the processed parts, and then easily reduces the efficiency of batch processing, so there is room for improvement. Summary of the invention

[0004] In order to improve the positioning efficiency of the processed parts, the present application provides a positioning tool for production and processing.

[0005] The present application provides a positioning tool for production and processing, which adopts the following technical solution: A positioning tool for production and processing includes a support seat, on which a pull pin and a control component are arranged. The control component is used to drive the pull pin to slide toward or away from the support seat, and the end of the pull pin away from the support seat is used to act on the processed part.

[0006] By adopting the above technical scheme, the support seat is installed on the processing table, and the control component is used to drive the rivet to reciprocate in the direction close to or away from the support seat. When the rivet moves in the direction away from the support seat and abuts against the processed part, the rapid positioning of the processed part is achieved by the pressing method. The rivet can also be pre-connected with a connector or a clamp, and the movement of the rivet can be used to drive the connector or the clamp to move in the direction close to the processed part, and the connector is used to connect the processed part, or the clamp is used to clamp the processed part, so as to achieve rapid positioning of the processed part. When the processed part needs to be replaced, it is only necessary to drive the rivet to move in the direction close to the support seat through the control component to make the rivet separate from the processed part, finally achieving rapid disassembly and assembly of the positioning tooling and the processed part, thereby improving the overall processing efficiency.

[0007] Preferably, the control assembly comprises a first movable seat, a first ball and a sliding member; a regulating cavity is provided inside the support seat, the first movable seat and the rivet are both slidably connected in the regulating cavity, and the sliding directions are parallel to each other; the sliding member is used to drive the first movable seat to slide; one end of the first movable seat is sleeved on the periphery of the rivet, and the first ball is a plurality of balls, which are inserted through the side wall of the first movable seat; The first ball is clamped between the peripheral wall of the rivet and the inner wall of the regulating cavity, and the peripheral wall of the rivet and the inner wall of the regulating cavity are both provided with a first pressing surface and a first yielding surface, the first pressing surface is used to push the first ball when in contact with the first ball, and the first yielding surface is used to allow the first ball to move toward the direction close to the first yielding surface when in contact with the first ball.

[0008] By adopting the above technical solution, the first movable seat is driven by the sliding member to move in the direction away from the rivet. At this time, the first ball moves in the direction away from the rivet under the joint action of the first yielding surface on the regulating cavity and the first pressing surface on the rivet surface, so that the rivet moves downward, thereby realizing the positioning connection between the rivet and the processed part. On the contrary, the first movable seat is driven by the sliding member to move in the direction close to the rivet. At this time, the first ball will move in the direction close to the rivet under the joint action of the first pressing surface on the inner wall of the regulating cavity and the first yielding surface on the rivet surface, and squeeze the rivet, so that the rivet moves in the direction close to the support seat, thereby realizing the separation of the rivet from the processed part.

[0009] Preferably, the sliding member comprises a fixed ring plate, a second movable seat, a second ball bearing, and an air supply component; the fixed ring plate and the second movable seat are both inserted into the control cavity, and the fixed ring plate is sleeved on the periphery of the first movable seat, and the second movable seat is sleeved on the periphery of the fixed ring plate; the fixed ring plate is fixed relative to the control cavity, and the second movable seat is slidably connected to the control cavity; The second movable seat and the fixed ring plate divide the regulating chamber into a first chamber, a second chamber and a third chamber, and the gas supply component is used to supply gas to the first chamber, the second chamber and the third chamber; The second ball is inserted into the fixed ring plate along the circumferential direction of the fixed ring plate, and the second ball is clamped between the first movable seat and the second movable seat; the second movable seat is provided with a docking inclined surface on the peripheral wall facing the second ball; the second movable seat is movably inserted between the second ball and the inner wall of the regulating cavity through the docking inclined surface; the first movable seat is provided with a second yielding surface and a second pressing surface on the peripheral wall facing the second ball, the second pressing surface is used to squeeze and push the second ball when it contacts the second ball, and the second yielding surface is used to allow the second ball to move toward the direction close to the second yielding surface when it contacts the second ball.

[0010] By adopting the above technical solution, by supplying air into the first chamber, the second driving seat moves toward the direction close to the first movable seat under the impetus of the airflow. At this time, the second ball will squeeze the first movable seat under the action of the yield slope and the second pressure surface, so that the first movable seat moves in the direction away from the rivet, and then the first ball moves in the direction away from the rivet under the joint action of the first yield surface on the regulating chamber and the first pressure surface on the rivet surface, so that the rivet moves downward, thereby realizing the positioning connection between the rivet and the processed part; on the contrary, by supplying air into the third chamber and the second chamber, the second ball moves in the direction away from the first movable seat under the action of the docking slope and the second yield surface, and at the same time, the first movable seat and the second movable seat move in the direction away from each other under the impetus of the airflow, that is, at this time, the first movable seat moves in the direction close to the rivet, and then the first ball moves in the direction close to the rivet under the joint action of the first pressure surface on the inner wall of the regulating chamber and the first yield surface on the rivet surface, and squeezes the rivet, so that the rivet moves in the direction close to the support seat, thereby realizing the separation of the rivet from the processed part.

[0011] Preferably, a base is disposed on the periphery of the support seat, the support seat is slidably connected inside the base, and the sliding direction of the support seat is parallel to the sliding direction of the rivet.

[0012] By adopting the above technical solution, since the rivet is located on the support seat, and the support seat can slide relative to the base, the sliding of the rivet can be further increased by means of the sliding of the support seat, so that the rivet can be suitable for positioning processed parts of different sizes and specifications, thereby improving applicability.

[0013] Preferably, a cleaning channel is provided inside the support seat, and the gas supply component is also used to transport gas into the cleaning channel. The cleaning channel runs through one end of the support seat near the rivet.

[0014] By adopting the above technical solution, some processing steps (such as cutting) are prone to produce debris during the processing. Therefore, the present application specially sets up a cleaning channel to blow towards the rivet position through air supply to reduce the accumulation of debris around the positioning tooling of the present application.

[0015] Preferably, the first movable seat and the side wall of the fixed ring plate are both provided with through holes, and the first ball and the second ball correspond to a through hole respectively; the first ball and the second ball are hinged to the corresponding inner walls of the through holes; and also include a swinging member, which is used to drive the first ball and the second ball to swing back and forth with their hinge points on the inner walls of the corresponding through holes as the center, and the rivet and the inner wall of the regulating cavity are on the swinging path of the first ball, and the first movable seat and the second movable seat are on the swinging path of the second ball.

[0016] By adopting the above technical solution, the first ball can be driven by the swinging member to move toward the first yielding surface in the regulating cavity, and the second ball can be driven to move toward the yielding inclined surface, thereby reducing the extrusion force of the first ball being squeezed by the pull pin to move the first ball toward the first yielding surface, and also reducing the extrusion force of the second ball being squeezed by the first movable seat to move the second ball toward the yielding inclined surface, thereby reducing the wear between the first ball and the pull pin, the first ball and the inner wall of the regulating cavity, the second ball and the first movable seat, and the second ball and the second movable seat, thereby reducing the travel accuracy and clamping stability of the pull pin, the first movable seat and the second movable seat affected by the aforementioned wear.

[0017] Preferably, the swing member includes an inner ring rod, an outer ring rod and a driving component; the inner ring rod, the outer ring rod and the through hole are arranged in a one-to-one correspondence, the first ball and the second ball are respectively located between the corresponding inner ring rod and the outer ring rod, and the driving component is used to drive any one of the inner ring rod and the outer ring rod to be inserted into the corresponding through hole and abut against the through hole at the same time; the first ball and the second ball are located close to the corresponding hinge point and on the insertion path when the inner ring rod and the outer ring rod are inserted into the through hole.

[0018] By adopting the above technical solution, the inner ring rod is inserted into the gap between the first ball or the second ball and the inner wall of the through hole, so that the first ball is squeezed by the inner ring rod and moves in the direction away from the rivet, and the second ball is squeezed by the inner ring rod and moves in the direction away from the first movable seat. By inserting the outer ring rod into the gap between the first ball or the second ball and the inner wall of the through hole, the first ball is squeezed by the outer ring rod and moves in the direction close to the rivet and squeezes the rivet, and the second ball is squeezed by the inner and outer ring rods and moves in the direction close to the first movable seat and squeezes the rivet, thereby cooperating with the airflow driving force to realize the rolling of the first ball and the second ball, and the smooth sliding of the first movable seat and the second movable seat.

[0019] Preferably, the driving component includes a docking ring plate and a motor, the inner ring rod and the outer ring rod are both connected to the docking ring plate, the first movable seat and the fixed ring plate are both rotatably connected to a docking ring plate, the motor is transmission connected to the docking ring plate to drive the docking ring plate to rotate, and the rotation center of the docking ring plate is located on the central axis of the first movable seat and the fixed ring plate.

[0020] By adopting the above technical solution, the rotation of the docking ring plate is used to drive the rotation of the inner ring rod and the outer ring rod, and because the rotation center of the docking ring plate is located on the central axis of the first movable seat and the fixed ring plate, and because the first balls are distributed circumferentially with the first movable seat and the second balls are distributed circumferentially with the fixed ring plate, the docking ring plate can drive the inner ring rod and the outer ring rod to be inserted into the corresponding through holes during the rotation process.

[0021] Preferably, the outer diameters of the inner ring rod and the outer ring rod increase with increasing insertion depth into the through hole.

[0022] By adopting the above technical solution, when wear occurs between the first ball and the rivet, and between the second ball and the first movable seat, the swing amplitude of the first ball and the second ball can be increased to ensure that the balls can clamp the first movable seat and the rivet, so as to reduce the situation where the first movable seat and the rivet are slipped due to wear. The method for increasing the swing amplitude of the first ball and the second ball proposed in the present application is to limit the outer diameters of the inner ring rod and the outer ring rod. Based on this, the insertion depth of the inner ring rod and the outer ring rod into the through hole (that is, the outer diameter of the contact part with the first ball or the second ball) can be adjusted to adjust the swing amplitude of the first ball and the second ball.

[0023] Preferably, a controller is further included, and the air supply component is controlled by the controller. The controller is used to control the opening and closing of the air supply component, and is also used to obtain the sliding stroke of the pull stud, and based on the sliding stroke of the pull stud, analyze and output the wear condition, and the wear condition at least includes the wear condition between the pull stud and the first ball.

[0024] By adopting the above-mentioned technical scheme, the controller can analyze whether the positioning tooling of the present application is worn based on the opening and closing control of the air supply components and the monitoring of the sliding stroke of the pull nail, so that the operator can know the wear condition in real time and deal with the positioning tooling that has reached the end of its service life in time, thereby reducing the impact on the positioning accuracy of the processed parts.

[0025] In summary, this application includes the following beneficial technical effects: The support seat is installed on the processing table, and the control component is used to drive the rivet to reciprocate toward or away from the support seat. When the rivet moves toward the direction away from the support seat and abuts against the workpiece, the workpiece is quickly positioned by pressing. The rivet can also be pre-connected with a connector or a clamp, and the movement of the rivet can be used to drive the connector or the clamp to move toward the workpiece, and the workpiece is connected with the connector, or the workpiece is clamped with the clamp, thereby realizing rapid positioning of the workpiece. When the workpiece needs to be replaced, it is only necessary to drive the rivet to move toward the support seat through the control component to separate the rivet from the workpiece, thereby finally realizing rapid disassembly and assembly of the positioning tooling and the workpiece, thereby improving the overall processing efficiency.

[0037] Reference Figure 3 and Figure 4 The control assembly 3 includes a first movable seat 31, a first ball 32 and a sliding member 33. The sliding member 33 includes a fixed ring plate 331, a second movable seat 332, a second ball 333 and an air supply component 334. The fixed ring plate 331 is fixedly inserted in the control cavity 21, the first movable seat 31 is inserted in the fixed ring plate 331, and the end of the first movable seat 31 is sleeved on the end of the rivet 4. The second movable seat 332 is inserted at the periphery of the fixed ring plate 331 and is located between the fixed ring plate 331 and the control cavity 21. The control cavity 21 is divided by the fixed ring plate 331 and the second movable seat 332 to form a first chamber 211, a second chamber 212 and a third chamber 213.

[0038] Reference Figure 3 and Figure 4 , there are multiple first balls 32 and multiple second balls 333, and the first balls 32 are distributed on the first movable seat 31 along the circumference of the first movable seat 31; the second balls 333 are evenly distributed along the circumference of the fixed ring plate 331. Correspondingly, through holes 335 are opened on the side walls of the fixed ring plate 331 and the first movable seat 31, and the first balls 32 and the second balls 333 correspond to one through hole 335 respectively, and are inserted through the corresponding through holes 335. The diameters of the first balls 32 and the second balls 333 are larger than the diameters of the corresponding through holes 335.

[0039] Reference Figure 3 and Figure 4 The first ball 32 extends out of the corresponding through hole 335 and abuts between the rivet 4 and the inner wall of the fixed ring plate 331. The peripheral wall of the rivet 4 and the inner wall of the fixed ring plate 331 are provided with a first pressing surface 41 and a first giving way surface 42. The first pressing surface 41 is used to push the first ball 32 when in contact with the first ball 32, and the first giving way surface 42 is used to allow the first ball 32 to move toward the first giving way surface 42 when in contact with the first ball 32.

[0040] Reference Figure 3 and Figure 4The second rolling ball 333 extends out of the corresponding through hole 335 and abuts between the first movable seat 31 and the second movable seat 332 . The second movable seat 332 is provided with a docking inclined surface 3321 on the peripheral wall facing the second ball 333, and the docking inclined surface 3321 makes the thickness of the second ball 333 gradually increase in the direction approaching the first chamber 211; the first movable seat 31 is provided with a second yielding surface 311 and a second pressing surface 312 on the peripheral wall facing the second ball 333, and the second pressing surface 312 is used to drive the first movable seat 31 to move in the direction approaching the first chamber 211 when it is resisted by the second ball 333, and is also used to move the second ball 333 in the direction away from the first movable seat 31 when the first movable seat 31 moves in the direction away from the first chamber 211 and resists the second ball 333 through the second pressing surface 312; the second yielding surface 311 is used to allow the second ball 333 to move in the direction close to the second yielding surface 311 when it contacts the second ball 333.

[0041] Reference Figure 2 , Figure 3 and Figure 4 The air supply component 334 is connected to the air source. The air supply component 334 specifically includes a clamping air path 3341 and an unlocking air path 3342. The clamping air path 3341 is connected to the first chamber 211. The gas is delivered to the first chamber 211 through the clamping air path 3341, so that the second movable seat 332 moves toward the direction close to the fixed ring plate 331 and the first movable seat 31 under the push of the air flow, so that the second ball 333 moves toward the direction close to the first movable seat 31 under the pressure of the docking inclined surface 3321, and squeezes The first movable seat 31, and then the first movable seat 31 drives the first ball 32 to move in the direction away from the pull pin 4 and close to the first chamber 211, and the first ball 32 will move in the direction close to the fixed ring plate 331 and away from the pull pin 4 under the action of the first yielding surface 42 on the fixed ring plate 331 during the movement of the first movable seat 31, thereby reducing the pressure on the pull pin 4, so that the pull pin 4 moves in the direction away from the support seat 2, that is, extends out of the regulating cavity 21, to achieve the positioning of the pull pin 4 and the processed part.

[0042] Reference Figure 3 and Figure 4Correspondingly, the unlocking gas path 3342 is connected to the third chamber 213, and gas is transported into the third chamber 213 through the unlocking gas path 3342, so that the second movable seat 332 moves toward the direction close to the first chamber 211 under the push of the airflow. At this time, part of the gas in the third chamber 213 will enter the second chamber 212 through the gap between the second movable seat 332 and the fixed ring plate 331, so that the first movable seat 31 moves away from the second chamber 212 under the push of the airflow in the second chamber 212. In this process, the second movable seat 332 moves in the direction close to the first chamber 211 under the push of the airflow. The ball 333 will move in the direction away from the first movable seat 31 under the action of the docking inclined surface 3321 and the second pressing surface 312, so as to reduce the movement resistance of the first movable seat 31 when it moves in the direction away from the second chamber 212, and the first ball 32 moves with the movement of the first movable seat 31, and presses the rivet 4 in the direction close to the rivet 4 under the action of the first pressing surface 41 on the fixed ring plate 331, so that the rivet 4 moves in the direction close to the support seat 2, that is, the rivet 4 extends into the regulating cavity 21, thereby realizing the separation of the rivet 4 from the processed part.

[0043] Reference Figure 2 and Figure 5 A cleaning channel 23 is provided inside the support seat 2, and the gas supply component 334 also includes a cleaning gas path 3343 which is connected to the cleaning channel 23 for conveying gas into the cleaning channel 23. The cleaning channel 23 is connected to the external environment through the gap of the support seat 2 near the pull nail 4 to achieve purging and cleaning of the environment around the pull nail 4.

[0044] Reference Figure 2 and Figure 6 The base 1 can be fixedly mounted on a workbench, and the outer wall of the support base 2 and the inner wall of the base 1 together enclose an adjustment chamber 22. When the support base 2 slides relative to the base 1, the size of the adjustment chamber 22 will change with the sliding of the support base 2. The air supply component 334 also includes an extended air path 3344 and a retracted air path 3345. The extended air path 3344 is connected to the end of the support base 2, and the retracted air path 3345 is connected to the adjustment chamber 22. The extended air path 3344 is used to deliver gas to the channel connected to the support base 2, so that the support base 2 moves relative to the support base 2 under the action of air pressure, so that the adjustment chamber 22 becomes larger; the air in the adjustment chamber 22 is extracted by the retracted air path 3345, so that the adjustment chamber 22 becomes smaller, and the corresponding support base 2 slides relative to the base 1.

[0045] Reference Figure 2 and Figure 3The air supply component 334 is electrically connected to a controller, and the controller includes a control module and a detection module electrically connected to the control module. The control module may be a PLC controller for controlling the on and off of the air supply component 334, and determining the air supply volume according to the working time of the air supply component 334 and a preset corresponding relationship table; wherein the corresponding relationship table is used to store the corresponding relationship between the air supply time and the air supply volume of each air path included in the air supply component 334. The detection module is used to detect the sliding stroke of the rivet 4. Accordingly, the detection module may be a distance measuring sensor, and the sliding stroke of the rivet 4 is determined by detecting the length of the rivet 4 extending outside the support seat 2. In other embodiments, the detection module may also be a camera device, and the length of the rivet 4 extending outside the support seat 2 is determined by taking real-time images of the rivet 4 extending outside the support seat 2, thereby obtaining the sliding stroke of the rivet 4.

[0046] Example 2 The difference between Example 2 and Example 1 is that: Reference Figure 7 and Figure 8 The first ball 32 and the second ball 333 are hinged to the inner wall of the corresponding through hole 335, and also include a swinging member 6, which is used to drive the first ball 32 and the second ball 333 to rotate around the corresponding hinge point, and the first ball 32 and the second ball 333 always fit the inner wall of the through hole 335 during the rotation process, that is, the inner wall of the through hole 335 is an arc surface for fitting with the surface of the first ball 32 or the second ball 333. The inner wall of the through hole 335 is on the swing path of the first ball 32, and the first movable seat 31 and the second movable seat 332 are on the swing path of the second ball 333. So that the first ball 32 presses the first pressing surface 41 of the pull nail 4 or the first yielding surface 42 of the inserted fixed ring plate 331 during the rotation process, and presses the second pressing surface 312 of the first movable seat 31 or contacts the docking inclined surface 3321 during the rotation process of the second ball 333.

[0047] Reference Figure 7 and Figure 8 The swing member 6 includes an inner ring rod 61, an outer ring rod 62 and a driving component 63, and the driving component 63 includes a docking ring plate 631, a motor 632 and a gear 633; ​​the inner ring rod 61, the outer ring rod 62 and the through hole 335 are arranged one by one, and the fixed ring plate 331 and the first movable seat 31 each correspond to a driving component 63, and the docking ring plate 631 is rotatably connected to the fixed ring plate 331 or the first movable seat 31 (such as according to Figure 8 The docking ring plate 631 is provided with a tooth groove meshing with the gear 633 on the peripheral wall, and the gear 633 is rotatably connected to the fixed ring plate 331 or the first movable seat 31, and the driving end of the motor 632 is fixedly passed through the corresponding rotation center of the gear 633.

[0048] Reference Figure 7 and Figure 8 The inner ring rod 61 and the outer ring rod 62 are connected to the docking ring plate 631 and are distributed along the circumference of the corresponding docking ring plate 631. When the inner ring rod 61 and the outer ring rod 62 rotate with the docking ring plate 631, they will pass through the through hole 335 and be inserted into the gap between the first ball 32 or the second ball 333 and the bottom wall of the through hole 335 (such as Figure 7 As shown by the arrow F in the middle, the first ball 32 or the second ball 333 is squeezed, so that the first ball 32 and the second ball 333 swing. When the inner ring rod 61 and the outer ring rod 62 rotate and insert into the gap, the outer diameters of the inner ring rod 61 and the outer ring rod 62 gradually increase along the rotation direction, that is, as the rotation angle increases, the squeezing force of the inner ring rod 61 and the outer ring rod 62 on the first ball 32 or the second ball 333 will increase. It should be noted that at the same time, the inner ring rod 61 and the outer ring rod 62 will not contact the corresponding first ball 32 and the corresponding second ball 333 at the same time, so as to ensure that the first ball 32 and the second ball 333 are only squeezed by one of the inner ring rod 61 and the outer ring rod 62 at the same time, or the inner ring rod 61 and the outer ring rod 62 are not rotated to the position of squeezing the first ball 32 and the second ball 333; Figure 8 The middle dotted line portion indicates the position of the vertical projection of the first rolling ball 32 or the second rolling ball 333 on the docking ring plate 631 .

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
