Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping fixture for assemblies. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for machining or inspection. When machining a workpiece on a machine tool, a fixture is used to ensure that the workpiece surface meets the technical requirements specified in the drawings, including dimensions, geometry, and positional accuracy relative to other surfaces.

[0003] A search revealed a utility model patent with Chinese patent publication number CN221455569U, which discloses a clamping fixture for assemblies, comprising a Y-shaped plate, a rotating shaft mounted on the upper wall of the Y-shaped plate, a cylindrical fixing block mounted on the upper wall of the rotating shaft, two pairs of L-shaped rods mounted on the side wall of the cylindrical fixing block, an annular plate mounted on the lower wall of the two pairs of L-shaped rods, a first rod mounted on the upper wall of the cylindrical fixing block, and a first box mounted on the upper wall of the first rod.

[0004] The device described above uses two clamping plates to hold parts. This method is only suitable for holding rectangular parts and cannot be used for holding cylindrical, elliptical, or other shaped parts. After the parts are clamped, the stability is insufficient, and there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping fixture for assembly processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for assemblies, comprising a platform, with two clamping assemblies installed inside the platform. Each clamping assembly includes a mounting frame placed on the inner wall of the top of the platform, a vertically arranged mounting seat rotatably connected inside the mounting frame, a toothed ring coaxially fixed to the outer circumference of the mounting seat, a horizontally arranged rectangular rod fixedly connected inside the mounting frame, a rack slidably sleeved on the outside of the rectangular rod, the rack meshing with the toothed ring, and two symmetrically arranged clearance grooves opened on the outer wall of the top of the platform, with the two mounting seats respectively located inside the two clearance grooves.

[0007] As a further preferred embodiment of this technical solution, a hydraulic cylinder is fixedly installed on the inner wall of the top of the platform. The hydraulic cylinder is parallel to the rack, and a movable frame is fixedly connected to the output end of the hydraulic cylinder. Both racks are slidably sleeved on the outside of the movable frame.

[0008] This allows the device to handle clamping work on parts of different shapes without the need for other types of clamps. The clamping plates are also easy to assemble and disassemble, which improves the adaptability of the device. For example, if the part to be processed is not rectangular, the hydraulic cylinder at the bottom of the platform is activated. The output end of the hydraulic cylinder drives the moving frame to move horizontally. The moving frame drives two racks to slide along the rod. The racks drive the gear ring to rotate through meshing. The gear ring drives the mounting base to rotate synchronously. Subsequently, the required clamping plates will move closer to each other. Because the racks are slidably sleeved outside the moving frame, the mounting frame can drive the racks to move normally, but the racks will not drive the gear ring to rotate.

[0009] As a further preferred embodiment of this technical solution, the top outer walls of both mounting bases are provided with several equally spaced limiting grooves, and each of the limiting grooves is slidably inserted with a clamping plate, and the four clamping plates are all different in shape.

[0010] As a further preferred embodiment of this technical solution, the two mounting frames are equipped with the same driving component. The driving component includes two support plates fixedly connected to the inner wall of the top of the platform, and two limiting rods fixedly connected between the two support plates. Both mounting frames are slidably sleeved on the outside of the two limiting rods.

[0011] As a further preferred embodiment of this technical solution, the two support plates are rotatably connected by the same bidirectional lead screw, and the two mounting frames are respectively threaded onto the threads at both ends of the bidirectional lead screw. A motor is fixedly installed on one side of the outer wall of one of the support plates, and the output end of the motor is coaxially fixed with one end of the bidirectional lead screw.

[0012] As a further preferred embodiment of this technical solution, each of the four support legs of the shelf is provided with a connecting plate on its exterior, and each of the four connecting plates has a through groove inside.

[0013] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread of the bidirectional lead screw is less than the equivalent frictional force.

[0014] This utility model provides a clamping fixture for assembly processing, which has the following advantages:

[0015] This invention, by setting up a clamping assembly, enables the device to adapt to the clamping of parts of different shapes, eliminating the need for other types of clamps. Furthermore, the clamping plates are easy to assemble and disassemble, which improves the adaptability of the device. For example, if the part to be processed is non-rectangular, the hydraulic cylinder at the bottom of the platform is activated. The output end of the hydraulic cylinder drives the moving frame to move horizontally. The moving frame drives two racks to slide along the rod. The racks mesh to drive the gear ring to rotate, and the gear ring drives the mounting base to rotate synchronously. Subsequently, the required clamping plates will move closer to each other. Because the racks are slidably sleeved outside the moving frame, the mounting frame can drive the racks to move normally, but the racks will not drive the gear ring to rotate.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown, in this embodiment, a clamping fixture for assembly processing includes a platform 1. Two clamping components 4 are installed inside the platform 1. The clamping components 4 include a mounting frame 401 placed on the inner wall of the top of the platform 1. A vertically arranged mounting seat 402 is rotatably connected inside the mounting frame 401. A toothed ring 403 is coaxially fixed on the outer circumference of the mounting seat 402. A horizontally arranged rectangular rod 404 is fixedly connected inside the mounting frame 401. A rack 405 is slidably sleeved on the outside of the rectangular rod 404. The rack 405 meshes with the toothed ring 403. Two symmetrically arranged clearance grooves 3 are opened on the outer wall of the top of the platform 1. The two mounting seats 402 are respectively located inside the two clearance grooves 3.

[0023] A hydraulic cylinder 7, preferably HFG5006, is fixedly installed on the inner wall of the top of the shelf 1. This type of hydraulic cylinder has a self-locking property. The hydraulic cylinder 7 is parallel to the rack 405. The output end of the hydraulic cylinder 7 is fixedly connected to the movable frame 6. Both racks 405 are slidably sleeved on the outside of the movable frame 6.

[0024] If the part to be processed is not rectangular, start the hydraulic cylinder 7 at the bottom of the platform 1. The output end of the hydraulic cylinder 7 drives the moving frame 6 to move horizontally. The moving frame 6 drives the two racks 405 to slide along the rod 404. The racks 405 drive the gear ring 403 to rotate through meshing. The gear ring 403 drives the mounting base 402 to rotate synchronously. Subsequently, the required clamping plates 407 will move closer to each other. Because the racks 405 are slidably sleeved on the outside of the moving frame 6, it ensures that the mounting frame 401 can drive the racks 405 to move normally, but the racks 405 will not drive the gear ring 403 to rotate.

[0025] like Figure 1 and Figure 2 As shown, the top outer wall of both mounting bases 402 is provided with several equally spaced limiting grooves 406. Each limiting groove 406 is slidably inserted with a clamping plate 407, and the four clamping plates 407 are all different in shape. If a clamping plate 407 with a special shape needs to be replaced, it can be quickly removed by simply pulling it upwards, and then it can be quickly replaced.

[0026] like Figure 2 and Figure 4 As shown, the two mounting frames 401 are equipped with the same driving component 5. The driving component 5 includes two support plates 501 fixedly connected to the inner wall of the top of the platform 1. Two limiting rods 503 are fixedly connected between the two support plates 501. Both mounting frames 401 are slidably sleeved on the outside of the two limiting rods 503.

[0027] The two support plates 501 are rotatably connected by the same bidirectional lead screw 502. The two mounting frames 401 are respectively threaded onto the threads at both ends of the bidirectional lead screw 502. A motor 504 is fixedly installed on one side of the outer wall of one of the support plates 501. The output end of the motor 504 is coaxially fixed with one end of the bidirectional lead screw 502.

[0028] Start a motor 504 outside a support plate 501. The output of the motor 504 drives the bidirectional lead screw 502 to rotate. The two mounting frames 401, which are restricted by two limit rods 503, can only move horizontally. The bidirectional lead screw 502 can drive the two mounting frames 401 to move closer to each other. The mounting frames 401 drive the clamping plates 407 to move synchronously through the mounting base 402 until the two clamping plates 407 clamp the parts.

[0029] like Figure 1 and Figure 2 As shown, each of the four support legs of the shelf 1 is provided with a connecting plate 2, and each of the four connecting plates 2 has a through groove, so that the shelf 1 can be installed on an external workbench through the connecting plates 2.

[0030] like Figure 2As shown, the thread helix angle of the external thread of the bidirectional lead screw 502 is less than the equivalent frictional force, giving it a self-locking property, thereby ensuring that the positions of the two mounting frames 401 connected to it will not change arbitrarily.

[0031] This utility model provides a clamping fixture for assembly processing, and its working principle is as follows:

[0032] When the device is working, if the part to be processed is non-rectangular, the hydraulic cylinder 7 at the bottom of the platform 1 is activated. The output end of the hydraulic cylinder 7 drives the moving frame 6 to move horizontally. The moving frame 6 drives the two racks 405 to slide along the rod 404. The racks 405 drive the gear ring 403 to rotate through meshing. The gear ring 403 drives the mounting base 402 to rotate synchronously. Subsequently, the required clamping plates 407 will move closer to each other. Because the racks 405 are slidably sleeved on the outside of the moving frame 6, it ensures that the mounting frame 401 can drive the racks 405 to move normally. The rack 405 does not drive the gear ring 403 to rotate. The part to be processed is placed between the two clamping plates 407. The motor 504 outside the support plate 501 is started. The output end of the motor 504 drives the bidirectional lead screw 502 to rotate. The two mounting frames 401, which are restricted by the two limit rods 503, can only move horizontally. The bidirectional lead screw 502 can drive the two mounting frames 401 to move closer to each other. The mounting frames 401 drive the clamping plates 407 to move synchronously through the mounting base 402 until the two clamping plates 407 clamp the part.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
