Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a clamp which is convenient for adjusting angles. Background Art

[0002] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture.

[0003] An existing patent (publication number: CN 220427576 U) discloses a clamp that is easy to adjust the angle. The clamping angle of the clamp is accurately adjusted to solve the problem in the prior art that the clamp needs to be repeatedly clamped and loosened with a flat jaw vise, which is cumbersome to operate and leads to low processing efficiency.

[0004] However, the above technical solution still has certain defects. The device adjusts the angle of the clamp by rotating the oblique rod. However, when the front and back sides of the object need to be processed, the staff needs to turn the object over again for clamping, which leads to low work efficiency. At the same time, when processing irregular objects, their surface shapes are mostly uneven, and the clamping plate can only be fixed at two points. The fixing effect is poor, which may cause the object to move during the processing and cause problems with the quality of the processed product. For this reason, a clamp that is easy to adjust the angle is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a clamp that is easy to adjust the angle to solve the technical problems raised in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for adjusting an angle, comprising a fixture assembly, the fixture assembly comprising a workbench, two groups of moving blocks are slidably connected inside the workbench, one side of the two groups of moving blocks are rotatably connected to an adjustment assembly, and one end of the adjustment assembly away from the moving block is fixedly connected to a clamping assembly;

[0007] The adjusting assembly includes a fixed shaft fixedly connected to one side of the moving block, a rotating circular plate is rotatably connected inside the fixed shaft, the rotating circular plate is fixedly welded with the rotating shaft at one end away from the moving block, and a connecting rod is welded to the end of the rotating circular plate away from the rotating shaft, the surface of the connecting rod is slidably connected to the limiting shaft, two groups of telescopic rods are fixedly connected to the side of the limiting shaft away from the rotating circular plate, and the ends of the two groups of telescopic rods away from the limiting shaft are provided with fixed circular plates fixedly connected to the surface of the connecting rod.

[0008] As an optimal technical solution for a clamp that is easy to adjust the angle of the utility model, a servo motor is installed on one side of the workbench, a bidirectional threaded screw is fixedly connected to the output end of the servo motor, and the two groups of moving blocks are rotatably connected to the bidirectional threaded screw.

[0009] As a preferred technical solution of the clamp for facilitating angle adjustment of the utility model, the connecting rod passes through the moving block and is connected to the rotating circular plate, and the connecting rod is slidably connected to the moving block.

[0010] As an optimal technical solution for the clamp that is easy to adjust the angle of the utility model, a pulling ring is fixedly connected to the surface of the telescopic rod movable rod, a limiting groove that matches the limiting axis is opened inside the moving block, and a turntable is welded to the end of the connecting rod away from the rotating circular plate.

[0011] As an optimal technical solution for a clamp that is easy to adjust the angle of the utility model, the clamping assembly includes a clamping plate fixedly connected to the end of the rotating shaft, a plurality of groups of spring grooves are opened inside the clamping plate, a spring is arranged inside the spring groove, a sliding plate is fixedly connected to the top of the spring, and a ball head rod is fixedly connected to the top of the sliding plate.

[0012] As a preferred technical solution of the clamp that is convenient for adjusting the angle of the utility model, the ball head rod is slidably connected to the clamp plate, and a protective sleeve is provided at the end of the ball head rod.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] The utility model pushes the pulling ring to move the limit shaft, and when the limit shaft moves, it squeezes the telescopic rod until it disengages from the limit groove. At this time, the rotating turntable drives the rotating circular plate to rotate through the connecting rod, so that the rotating circular plate drives the clamping plate to rotate through the rotating shaft, and then the pulling ring is loosened to make the limit shaft re-embedded in the limit groove, completing the fixation of the connecting rod, effectively preventing the object from moving during processing, which would cause quality problems of the processed object, and at the same time rotating according to the required processing position, avoiding secondary clamping of the object, and further improving the processing efficiency.

[0015] The utility model uses multiple groups of ball head rods to fit the surface of the object and receive force, so that the ball head rods squeeze the springs until the ball head rods on both sides fix the object. The ball head rods can also effectively fix objects with irregular surfaces, effectively enhancing the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A fixture that facilitates angle adjustment, such as Figure 1-5 As shown, the fixture assembly 100 includes a workbench 110, two groups of moving blocks 140 are slidably connected inside the workbench 110, one side of the two groups of moving blocks 140 are rotatably connected to the adjustment assembly 200, and the end of the adjustment assembly 200 away from the moving block 140 is fixedly connected to the clamping assembly 300;

[0027] The adjustment assembly 200 includes a fixed shaft 210 fixedly connected to one side of the moving block 140, a rotating circular plate 220 is rotatably connected inside the fixed shaft 210, a rotating shaft 230 is fixedly welded to the end of the rotating circular plate 220 away from the moving block 140, and a connecting rod 240 is welded to the end of the rotating circular plate 220 away from the rotating shaft 230, a limiting shaft 250 is slidably connected to the surface of the connecting rod 240, two groups of telescopic rods 260 are fixedly connected to the side of the limiting shaft 250 away from the rotating circular plate 220, and a fixed circular plate 270 fixedly connected to the surface of the connecting rod 240 is provided at one end of the two groups of telescopic rods 260 away from the limiting shaft 250.

[0028] The servo motor 120 is started to drive the bidirectional threaded screw 130 to rotate so that the two sets of moving blocks 140 can move relative to each other, and then the object is clamped and fixed by the clamping assembly 300 for processing. When the object needs to be processed at different angles, the staff pushes the pulling ring 280 to move the limiting shaft 250. When the limiting shaft 250 moves, it squeezes the telescopic rod 260 until it is out of the limiting groove. At this time, the rotating turntable 290 drives the rotating circular plate 220 to rotate through the connecting rod 240, so that the rotating circular plate 220 drives the clamping plate to rotate through the rotating shaft 230, and then the pulling ring 280 is released to allow the limiting shaft 250 to be re-embedded in the limiting groove 141, completing the fixation of the connecting rod 240, effectively preventing the object from moving during processing, resulting in problems with the quality of the processed object, and at the same time rotating according to the required processing position, avoiding secondary clamping of the object, and further improving the processing efficiency.

[0029] Please refer to Figure 1 A servo motor 120 is installed on one side of the workbench 110 , a bidirectional threaded screw 130 is fixedly connected to the output end of the servo motor 120 , and two sets of moving blocks 140 are rotatably connected to the bidirectional threaded screw 130 .

[0030] The two sets of moving blocks 140 are relatively moved by rotating the bidirectional threaded screw 130, so as to facilitate clamping of objects.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4 The connecting rod 240 passes through the moving block 140 and is connected to the rotating circular plate 220, and the connecting rod 240 is slidably connected to the moving block 140. A pulling ring 280 is fixedly connected to the surface of the movable rod of the telescopic rod 260. A limiting groove 141 that matches the limiting shaft 250 is opened inside the moving block 140. A turntable 290 is welded to the end of the connecting rod 240 away from the rotating circular plate 220.

[0032] Through the cooperation between the limiting shaft 250 and the limiting groove 141, the object can be effectively prevented from shaking during the processing.

[0033] Please refer to Figure 1 and Figure 5 The clamping assembly 300 includes a clamping plate 310 fixedly connected to the end of the rotating shaft 230, a plurality of spring grooves 311 are opened inside the clamping plate 310, a spring 320 is arranged inside the spring groove 311, a sliding plate 330 is fixedly connected to the top of the spring 320, a ball head rod 340 is fixedly connected to the top of the sliding plate 330, the ball head rod 340 is slidably connected to the clamping plate 310, and a protective sleeve is provided at the end of the ball head rod 340.

[0034] When clamping an object, when the ball head rods 340 on both sides are in contact with the surface of the object, multiple groups of ball head rods 340 are in contact with the surface of the object and are subjected to force, so that the ball head rods 340 squeeze the springs until the ball head rods 340 on both sides fix the object. The ball head rods 340 can also effectively fix objects with irregular surfaces, effectively enhancing the applicability of the device.

[0035] When in use, the servo motor 120 is started to drive the bidirectional threaded screw 130 to rotate so that the two groups of moving blocks 140 move relative to each other. When the ball head rods 340 on both sides are in contact with the surface of the object, the multiple groups of ball head rods 340 are in contact with the surface of the object and are subjected to force, so that the ball head rods 340 squeeze the springs until the ball head rods 340 on both sides fix the object. The ball head rods 340 can also effectively fix objects with irregular surfaces, which effectively enhances the applicability of the device. When it is necessary to process the object at different angles, the staff pushes the pull ring 280 to move the limit shaft 250. When the limit shaft 250 moves, it squeezes the telescopic rod 2 60 until it is out of the limiting groove, at this time, the rotating turntable 290 drives the rotating circular plate 220 to rotate through the connecting rod 240, so that the rotating circular plate 220 drives the clamping plate to rotate through the rotating shaft 230, and then the pulling ring 280 is loosened to make the limiting shaft 250 re-embedded in the limiting groove 141, completing the fixation of the connecting rod 240, effectively preventing the object from moving during processing, causing quality problems of the processed object, and at the same time rotating according to the required processing position, avoiding secondary clamping of the object, and further improving the processing efficiency. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
