Technical Field
[0001] This utility model relates to the field of accessory welding and processing technology, and in particular to a clamping and positioning device for an assembly machine. Background Technology
[0002] An assembly machine is a specialized piece of equipment used for workpiece positioning, clamping, and initial fixation. It can precisely assemble workpieces according to preset dimensions, angles, and positional relationships through a mechanical structure, and temporarily fix them through a clamping and positioning device, laying the foundation for subsequent cutting, grinding, welding, riveting, and other processes.
[0003] A Chinese patent with publication number CN218396731U discloses a clamping and positioning mold for an H-beam assembly machine, including a worktable and a clamping mechanism installed on the top of the worktable. The workpiece to be clamped is installed on the clamping mechanism, and a limit mechanism is also installed on one side of the top of the worktable corresponding to the position of the clamping mechanism. The clamping mechanism includes a rotary table, and a mounting column is fixedly connected to the center of the bottom of the rotary table, which greatly facilitates the operation of the operator.
[0004] Based on the above, the inventor believes that the existing clamping and positioning devices of the current assembly machine generally have the problem of single function during operation. Although they can clamp and position the workpiece, if the function of guiding and conveying the workpiece after the clamping state is released is to be achieved, an additional roller frame is required to work together. This makes it difficult to quickly switch between the two operation modes of clamping and guiding and conveying, thus affecting the overall operation efficiency of the equipment. Utility Model Content

[0010] A further feature of this invention is that the guide includes a bracket fixedly connected to the outside of the mounting block and rotating rods rotatably mounted on the bracket at both ends.
[0011] By adopting the above technical solution, when the rotating rod contacts the workpiece surface, it can provide conveying guidance for the workpiece moving back and forth.

[0013] By adopting the above technical solution, the rotation and static state of the shaft column can be controlled by the control component.
[0014] A further feature of this invention is that the control component includes a drive component mounted on the clamp for connection with the rotating shaft. The drive component on the same side of the clamp is integrally connected via a timing frame, and the timing frame is fixedly connected to the piston rod of the cylinder.
[0015] By adopting the above technical solution, the piston rod of the cylinder moves up and down, driving the synchronous frame to achieve the same vertical linear movement.
[0016] A further feature of this invention is that the drive assembly includes a gear fixed coaxially with the rotating shaft and a drive rod disposed on the outside of the clamping plate in a linear sliding manner, the drive rod having a toothed groove for meshing with the gear.
[0017] By adopting the above technical solution, the gears are controlled to rotate in different directions, so as to quickly adjust the working position of the guide and the pad.
[0018] A further feature of this invention is that a base frame is fixedly installed at the bottom end of the drive rod, and the end of the base frame away from the drive rod is fixedly connected to the synchronization frame.
[0019] By adopting the above technical solution, the drive rod can move up and down synchronously to control the rotation direction of the gear and facilitate switching the working mode of the workpiece.
[0020] A further feature of this invention is that a locking component for improving steering locking force is provided on the outer side of the rotating shaft.
[0021] By adopting the above technical solution, the rotating shaft is symmetrically provided at two locations on the outside of the shaft column.
[0022] A further feature of this invention is that a locking groove is provided on the outer side of the rotating shaft, and the locking assembly includes a connector disposed on the outer side of the clamping plate to be detachably connected to the locking groove.

[0025] By adopting the above technical solution, when the rotating shaft needs to be rotated, the synchronizing rod can be pushed manually.
[0026] The beneficial effects of this utility model are:
[0027] During workpiece processing, the clamping plate moves the pad towards the workpiece to position and clamp it, facilitating operation. After assembly, the clamping plate is reset, and the positions of the pad and guide are switched via the control component, allowing for quick interchange of their working positions. The rotating rod contacts the workpiece surface to guide the processed workpiece. Switching between the two working modes is simple and quick, reducing the need for workers to perform additional positioning steps on the pulley frame and improving work efficiency.

Detailed Implementation
[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0036] This utility model embodiment specifically provides a clamping and positioning device for an assembly machine. Please refer to... Figures 1-5 It includes a frame 1, on which a rotatable conveyor roller 2 is mounted, and the conveyor roller 2 is provided with a clamping plate 3 for holding steel parts.
[0037] Among them, the above-mentioned components are all commonly used components of existing assembly machines. There are three clamping plates 3 on the left and right sides of the frame 1 respectively, and the bottom ends of the clamping plates 3 on the same side are connected into an integral structure by steel structural components. The steel structural components are connected to the existing drive unit 33 that provides sliding force for the clamping plates 3, so that the clamping plates 3 on both sides can move closer or further apart under the drive of the drive unit 33, so as to realize the welding clamping or separation of the workpiece.
[0038] For the assembly machine, this equipment is used for the welding station of the workpiece. Its main function is to straight-line convey and clamp the workpiece for welding. After welding, the workpiece is continued to be conveyed to other processing positions of the assembly machine. The frame 1 is connected to the conveying part of the assembly machine in a straight line, which facilitates the feeding of the workpiece and its subsequent conveying to other processing positions of the assembly machine.
[0039] Furthermore, the clamping plate 3 has an installation port 31, and an adapter component 4 is installed inside the installation port 31. The clamping plate 3 contacts the workpiece through the adapter component 4, realizing two different operations of welding clamping and conveying guidance of the workpiece. A control component 5 is installed on the outside of the clamping plate 3. The operating state of the adapter component 4 is controlled by the control component 5, thereby switching the contact state between the adapter component 4 and the workpiece. This facilitates clamping and applying force to the workpiece when it needs to be welded and fixed, and guides the workpiece for conveying after welding, thus improving the convenience of conveying.
[0040] Specifically, the adapter component 4 includes a shaft 41 rotatably disposed in the mounting port 31 and a mounting block 42 integrally fixed to the outside of the shaft 41. The mounting block 42 has a sticking block 43 and a guide 44 fixed at both ends respectively. When the sticking block 43 contacts the workpiece surface, the workpiece can be clamped by applying force to the workpiece surface through the sticking block 43 when the spaced clamping plates 3 are close together.
[0041] In practice, the guide 44 includes a bracket 441 fixedly connected to the outside of the mounting block 42 and a rotating rod 442 rotatably mounted on the bracket 441 at both ends. The rotating rod 442 is perpendicular to the ground as a whole, so that when the rotating rod 442 contacts the workpiece surface, it can provide conveying guidance for the workpiece moving back and forth.
[0042] In this embodiment, by applying a 180° rotation to the shaft 41, the positions of its two end blocks 43 and rotating rod 442 can be changed, thereby facilitating cooperation with the clamping plate 3. When the workpiece needs to be welded, the blocks 43 contact the workpiece surface to achieve clamping. When the workpiece needs to be transported, the clamping plates 3 are first moved away from each other to provide space for the rotation of the shaft 41. Then, after the shaft 41 is rotated 180°, the rotating rod 442 contacts the workpiece surface and achieves guidance.
[0043] Among them, a rotating shaft 411 is coaxially fixed on the outer side of the shaft column 41. The rotating shaft 411 is rotatably installed in the clamping plate 3, and one end of the rotating shaft 411 passes through the clamping plate 3 and is connected to the control component 5, so that the rotation and stationary state of the shaft column 411 can be controlled by the control component 5, thereby enabling quick adjustment of the working position of the guide 44 and the patch 43.
[0044] Specifically, the control component 5 includes a drive component 51 mounted on the clamping plate 3 for connection with the rotating shaft 411. The drive component 51 on the same side of the clamping plate 3 is integrally connected through a timing frame 52. The timing frame 52 is fixedly connected to the piston rod of the cylinder 53. "Same side" means that they are located on the left or right side of the frame 1. The drive component 51 on the same side is integrally driven through the timing frame 52. The cylinder 53 is fixedly installed on the outside of one of the clamping plates 3 on the same side, so that the piston rod of the cylinder 53 moves up and down, driving the timing frame 52 to achieve the same stroke of vertical linear movement.
[0045] In implementation, the drive assembly 51 includes a gear 511 coaxially fixed with the rotating shaft 411 and a drive rod 512 disposed on the outside of the clamping plate 3 in a linear up-and-down sliding manner. A sliding sleeve 32 with an inner wall slidably connected to the drive rod 512 is fixedly installed on the outside of the clamping plate 3 so that the drive rod 512 can stably maintain linear up-and-down sliding. The drive rod 512 is provided with a tooth groove 513 for meshing with the gear 511, so that the drive rod 512 can provide transmission and reset to the gear 511 through the tooth groove 513, so that the gear 511 can rotate forward and backward. It is convenient to control the gear 511 to achieve rotation in different directions by moving the drive rod 512 up and down, so as to quickly adjust the working position of the guide 44 and the patch 43.
[0046] The bottom end of the drive rod 512 is fixedly mounted with a base frame 514. The end of the base frame 514 away from the drive rod 512 is fixedly connected to the timing frame 52, so that the timing frame 52 can move up and down to drive the drive rod 512 to move up and down synchronously, thereby controlling the rotation direction of the gear 511 and facilitating the switching of the working mode of the workpiece.
[0047] Furthermore, a locking component 6 for improving steering locking force is provided on the outer side of the rotating shaft 411. The rotating shaft 411 has two symmetrical locations on the outer side of the shaft column 41. One location extends through the clamping plate 3 and is connected to the control component 5, while the other location extends through the clamping plate 3 and is connected to the locking component 6.
[0048] Specifically, a locking groove 412 is provided on the outer side of the rotating shaft 411. The locking assembly 6 includes a connector 61 located on the outer side of the clamping plate 3 and detachably connected to the locking groove 412. The connector 61 on the clamping plate 3 on the same side is fixedly connected by a synchronizing rod 62. The connection between the connector 61 and the locking groove 412 enables the rotating shaft 411 to obtain a locking force during daily use, so as to ensure the stability of the guide 44 and the pad 43 during operation and prevent the shaft column 41 from rotating.
[0049] The inner wall of the locking groove 412 is a polygonal structure. The connecting piece 61 includes a locking rod 611 that is inserted into the inner wall of the locking groove 412 and a side plate 612 that is fixedly connected to the outer end of the locking rod 611. Through the design of the polygonal mechanism, the locking rod 611 can provide a circumferential rotation locking force for the rotating shaft 411 after being inserted into the locking groove 412. The bottom end of the side plate 612 is fixedly connected to the synchronizing rod 62 through the connecting bracket 613. The side plates 612 on the same side are all fixed together with a synchronizing rod 62. The synchronizing rod 62 is slidably installed on the outside of the clamping plate 3, and the sliding direction of the synchronizing rod 62 is parallel to the length direction of the frame 1. When it is necessary to rotate the rotating shaft 411, the synchronizing rod 62 can be pushed manually to move the locking rod 611 out of the locking groove 412. After the rotating shaft 411 is rotated, the locking rod 611 is reset to continue to provide locking protection.
[0050] During implementation, a mounting base 63 is fixedly provided on the outer side of the clamping plate 3, and the outer side of the synchronizing rod 62 on the same side is slidably connected to the mounting base 63 to facilitate the synchronizing rod 62 to achieve stable forward and backward linear sliding.
[0051] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.
[0052] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
