[0002] A device used to fix the object to be processed 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] In the prior art, China's publication number is: CN216939497U, a fixture for machining mechanical parts that can be quickly positioned, including a workpiece clamping table, the top of the workpiece clamping table is slidably connected to two symmetrical sliding seats, the top of the sliding seat is rotatably connected to a rotating shaft through a bearing, and the outer side of the rotating shaft is fixedly connected to a clamping plate. This fixture for machining mechanical parts that can be quickly positioned is different from the prior art. During the use of the fixture for machining mechanical parts that can be quickly positioned, the sliding seat, the rotating shaft, the clamping plate, the L-shaped moving column, the arc channel, the spring, the sliding seat, the moving block, and the electric push rod can be used. By starting the electric push rod and cooperating with multiple corresponding parts, the parts can be conveniently and quickly positioned, and the clamping effect is good. Secondly, the synchronous adjustment mechanism can be used to synchronously adjust the distance between the two sliding seats 1 and the sliding seat 2, so as to achieve the purpose of clamping and fixing parts of different sizes.

During general machining, common components that need to be clamped include cylindrical components. The device cannot meet the clamping requirements of cylindrical components and has certain limitations. Utility Model Content

During general mechanical processing, common components that need to be clamped also include cylindrical components. The device cannot meet the clamping requirements of cylindrical components and has certain limitations.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a clamp that can be quickly positioned, comprising: an operating table, a bidirectional screw rod 1 is installed on the top bearing of the outer surface of the operating table, a rocker rod 1 is fixedly connected to the end of the bidirectional screw rod 1 away from the operating table, two bearing plates are threadedly installed on the outer surface of the bidirectional screw rod 1, a guide rod 1 is fixedly installed on the top of the outer surface of the operating table, a limit block is fixedly connected to the end of the guide rod 1 away from the operating table, the guide rod 1 penetrates and is movably embedded in the interior of the two bearing plates, and strip grooves are provided on the opposite outer surfaces of the two bearing plates.

[0007] As a preferred embodiment, the inner walls opposite to each other of the two strip grooves are both bearing-mounted with a two-way screw rod 2, the outer surfaces of the two two-way screw rods 2 are both threadedly mounted with two threaded blocks, and the tops of the outer surfaces of the four threaded blocks are fixedly mounted with a triangular plate.

[0008] The technical effect of adopting the above-mentioned further scheme is: when in use, the rocker one is rotated, and under the limiting action of the guide rod one, the two bearing plates are close to each other, and the cylindrical workpiece can be fixedly clamped through the relative inclined surfaces of each group of triangular plates, and the distance between the upper and lower groups of threaded blocks and each group of triangular plates is adjusted synchronously to facilitate better clamping of cylindrical workpieces of different thicknesses. By changing the distance between the two threaded blocks in each group, the opposite surfaces of the two threaded blocks are made to contact the two sides of the square workpiece without clamping, and then the rocker one is rotated to make the two bearing plates close to each other, so that the square workpiece can be clamped. This device can clamp cylindrical workpieces and square workpieces of different sizes.

[0009] As a preferred embodiment, guide rods 2 are fixedly installed on the opposite inner walls of the two strip grooves, and the two guide rods 2 and the four threaded blocks are evenly divided into two groups, and each group of guide rods 2 is movably embedded in the interior of the two threaded blocks.

[0010] The technical effect of adopting the above further solution is that the second guide rod has a guiding and limiting effect on the threaded block, so that the threaded block can only move horizontally.

[0011] As a preferred embodiment, one end of the two bidirectional screw rods 2 penetrates and is movably embedded in the outer surface of the two bearing plates, and one end of the two bidirectional screw rods 2 is fixedly mounted with a bevel gear 1.

[0012] The technical effect of adopting the above further solution is: by rotating the two bevel gears 1, the two bidirectional screw rods 2 can be driven to rotate.

[0014] The technical effect of adopting the above-mentioned further scheme is: the two rotating rods drive the two bevel gears to rotate synchronously, so that the two bevel gears drive the two bidirectional screws to rotate, and the distance between the upper and lower sets of threaded blocks and each set of triangular plates is synchronously adjusted, so that the center lines of different workpieces are always in the same position, and then the workpieces are effectively positioned according to the size of the workpieces, which is convenient for later processing.

[0015] As a preferred embodiment, the opposite ends of the two rotating rods are fixedly connected with telescopic blocks, one end of one of the rotating rods penetrates and is movably embedded in the outer surface of one of the mounting plates, and one end of one of the rotating rods is fixedly connected with rocker arm 2.

[0016] The technical effect of adopting the above further solution is: when in use, when the two bearing plates are moved by the telescopic block, the relative positions of the two sets of bevel gears 1 and 2 will not change, and the rocker 2 is rotated to make the two rotating rods rotate simultaneously.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] 1. When the utility model is in use, the first rocker is rotated, and the two bearing plates are brought closer to each other. The cylindrical workpiece can be fixedly clamped by the inclined surfaces relative to each set of triangular plates. The second rocker is rotated, so that the two rotating rods drive the two bevel gears to rotate synchronously, so that the two bevel gears drive the two bidirectional screws to rotate, and the distance between the upper and lower sets of threaded blocks and each set of triangular plates is adjusted synchronously, so as to better clamp cylindrical workpieces of different thicknesses. By changing the distance between the two threaded blocks in each set, the opposite surfaces of the two threaded blocks are in contact with the two sides of the square workpiece without clamping. Then the first rocker is rotated to bring the two bearing plates closer to each other, so as to clamp the square workpiece. The device can meet the needs of clamping cylindrical workpieces and square workpieces of different sizes.

[0019] 2. When the utility model is in use, the telescopic block can be extended or shortened by force, so that when the two bearing plates move, the relative positions of the two groups of bevel gears 1 and bevel gear 2 will not change, the bidirectional screw rod 1 drives the two bearing plates to move synchronously, so that the center plane between the two bearing plates remains unchanged, and the bidirectional screw rod 2 drives each group of threaded blocks to move synchronously, so that the center plane between each group of threaded blocks remains unchanged, so that the center lines of different workpieces after clamping are always in the same position, and then according to the size of the workpiece, the workpiece can be effectively and quickly positioned, which is convenient for later processing.
