Description

Technical Field

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

[0002] In the machining process of mechanical parts, fixtures are usually used to clamp the parts. The clamping fixture can firmly fix the workpiece in the accurate position, so that the workpiece will not be displaced or vibrated due to cutting force, gravity or other factors during the machining process. This ensures that each machining process is carried out on an accurate reference and reduces machining errors.

[0003] Currently, when machining rod-shaped parts, it is generally necessary to clamp the parts horizontally or vertically to facilitate the machining of the outer wall of the parts. However, the existing clamping fixtures have relatively fixed clamping directions. When it is necessary to machine oblique holes in the rod wall of the part, it is impossible to rotate and support the part at a certain angle, which results in a limited clamping range of the clamping fixture and reduces the effectiveness of the fixture. Utility Model Content

[0004] In view of the problems existing in the existing clamping fixtures for machining mechanical parts, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a clamping fixture for machining mechanical parts, which solves the problem that existing clamping fixtures cannot clamp parts at different angles.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping fixture for machining mechanical parts includes a base plate and a support base fixedly disposed on the top of the base plate. Rotating rods are rotatably passed through both sides of the upper end of the support base. A first storage cylinder is fixedly disposed between the two rotating rods. An inclined support mechanism is provided on the top of the base plate, and a support frame is provided through the inclined support mechanism. Support rods are rotatably passed through both sides of the support frame. A second storage cylinder is fixedly disposed at one end of the two support rods close to each other. An adjusting clamping mechanism is provided inside both the first and second storage cylinders.

[0008] Preferably, the tilting support mechanism includes an adjusting screw, which is rotatably inserted into the lower end of the support base. A movable frame is threaded onto the wall of the adjusting screw, and the movable frame is in contact with the top of the base plate. Two symmetrically arranged push plates are rotatably mounted on the upper end of the frame via a pivot pin. The upper end of the push plates is rotatably mounted on the outside of the support rod.

[0009] Preferably, the adjusting clamping mechanism includes a push screw, which is threaded inside the first storage cylinder. One end of the push screw is rotatably fitted with a sleeve, which is located inside the first storage cylinder. The other end of the push screw is fixedly fitted with a drive rocker.

[0010] Preferably, an auxiliary reinforcing plate is fixedly provided on the top of the base plate, and the end of the adjusting screw away from the support seat is rotatably inserted into the auxiliary reinforcing plate.

[0011] Furthermore, a positioning ring is fixedly provided on the upper end of the outer wall of the support base. The positioning ring is sleeved on the outside of the rotating rod. The outer wall of the positioning ring is engraved with a plurality of angle scale lines arranged symmetrically around the base. An indicator protrusion is fixedly provided at the end of the rotating rod. The indicator protrusion is configured to cooperate with the angle scale lines.

[0012] Preferably, the interior of both the support base and the support frame is U-shaped.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a clamping fixture for machining mechanical parts.

[0024] This utility model provides, for example Figure 1-3 A clamping fixture for machining mechanical parts is shown, comprising a base plate 1 and a support base 2 fixedly mounted on the top of the base plate 1. Rotating rods 3 are rotatably inserted through both sides of the upper end of the support base 2. A first storage cylinder 4 is fixedly mounted between the two rotating rods 3. An inclined support mechanism is provided on the top of the base plate 1, and a support frame 5 is provided through the inclined support mechanism. The interiors of the support base 2 and the support frame 5 are both U-shaped. Support rods 6 are rotatably inserted through both sides of the support frame 5. A second storage cylinder 7 is fixedly mounted at one end of the two support rods 6 that are close to each other. The inclined support mechanism includes an adjusting screw 8, which is rotatably inserted through the lower end of the support base 2. An auxiliary reinforcing plate 14 is fixedly mounted on the top of the base plate 1. The end of the adjusting screw 8 away from the support base 2 is rotatably inserted through the auxiliary reinforcing plate 14. A movable frame 9 is threaded onto the wall of the adjusting screw 8. The movable frame 9 is in contact with the top of the base plate 1, and two symmetrically arranged push plates 10 are rotatably mounted on the upper end of the base plate 1 via a pivot pin. The upper end of the push plate 10 is rotatably mounted on the outside of the support rod 6.

[0025] To ensure the accuracy of tilting and clamping the parts, such as Figure 1-2 As shown, a positioning ring 15 is fixedly provided on the upper end of the outer wall of the support base 2. The positioning ring 15 is sleeved on the outside of the rotating rod 3. The outer wall of the positioning ring 15 is engraved with a plurality of angle scale lines arranged symmetrically around it. An indicator protrusion 16 is fixedly provided at the end of the rotating rod 3. The indicator protrusion 16 is configured to cooperate with the angle scale lines.

[0026] In order to stably clamp and fix the parts in the first storage cylinder 4 and the second storage cylinder 7, such as Figure 1 and Figure 3As shown, both the first storage cylinder 4 and the second storage cylinder 7 are equipped with an adjustment clamping mechanism. The adjustment clamping mechanism includes a push screw 11, which is threaded inside the first storage cylinder 4. One end of the push screw 11 is rotatably fitted with a sleeve 12, which is located inside the first storage cylinder 4. The other end of the push screw 11 is fixedly fitted with a drive rocker arm 13.

[0027] Operation method:

[0028] Before processing the parts, the first storage cylinder 4 and the second storage cylinder 7 are first located on the same horizontal line. The parts can be placed between the first storage cylinder 4 and the second storage cylinder 7, and the two drive rockers 13 are rotated at the same time, so that the drive rockers 13 drive the push screw 11 to rotate. At this time, under the rotation of the push screw 11, the two sleeves 12 are fitted on both ends of the parts and begin to stably clamp and position the two ends of the parts. At this time, the parts can be processed in the lateral position.

[0029] When it is necessary to machine oblique holes on the side wall of the part, the adjusting screw 8 can be rotated. At this time, the moving frame 9 moves laterally under the push of the adjusting screw 8. During this process, through the rotational cooperation of the moving frame 9 and the push plate 10, as well as the push plate 10 and the support rod 6, the support frame 5 can drive one end of the part to move slowly upward. During the rotation of the part, the first storage cylinder 4 inside the support seat 2 drives the rotating rod 3 to rotate. Thus, with the precise cooperation of the indicator protrusion 16 on the rod wall of the rotating rod 3 and the angle scale line on the outer wall of the positioning ring 15, the rotation angle of the part can be determined, ensuring the fixed rotation position of the part and the subsequent machining accuracy, and improving the overall multi-functionality of the clamping fixture.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
