Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a workpiece clamping mechanism. Background Art

[0002] A fixture is a device or mechanism used to clamp, fix or maintain the position of an object. They are commonly used in equipment in mechanical engineering, manufacturing and other fields. The design of the clamping mechanism can achieve a variety of different functions as needed, such as maintaining the position of an object, fixing an object, adjusting the position or direction of an object, etc. Common clamping mechanisms include clamps, fixtures, pliers, clamping claws, etc., which can achieve clamping operations through mechanical, hydraulic, pneumatic or electric means.

[0003] The existing Chinese patent with authorization announcement number CN209754964U discloses a workpiece clamping device, which is characterized in that it includes a fixed clamp, a movable clamp, a driving member and a spring. The above-mentioned movable clamp includes a connecting section and a clamping section in the shape of a straight section. The connecting section and the clamping section are vertically arranged. The connecting section is movably connected to the fixed clamp and a clamping opening for clamping the workpiece is formed between the clamping section and the fixed clamp. The two ends of the above-mentioned spring are respectively connected to the connecting section and the fixed clamp and the clamping section and the fixed clamp have a tendency to close under the elastic force of the spring. The above-mentioned driving member is connected to the fixed clamp and the driving member is connected to the connecting section. The driving member can drive the movable clamp to translate relative to the fixed clamp.

[0004] When using the clamping device, the movable clamp is installed first. After the movable clamp is installed, the workpiece to be clamped is placed between the clamping part and the clamping section. Then the spring moves the clamping part to the side close to the clamping section, so that the clamping part and the clamping section clamp the workpiece.

[0005] With respect to the above-mentioned related technologies, the inventors believe that before clamping the workpiece, the clamp needs to be installed first, and then the workpiece is clamped after the clamp is installed. In addition, the stability of clamping the workpiece by means of a spring is poor, which is not practical. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a workpiece clamping mechanism.

[0033] Reference Figure 1 A workpiece clamping mechanism includes a base 1, a clamping block 3 is provided on the base 1, and a clamping groove 11 is formed between the clamping block 3 and the base 1. An adjusting component 2 is provided on the base 1, and the adjusting component 2 adjusts the distance between the clamping groove 11 between the clamping block 3 and the base 1. In addition, a controllable magnetic seat 4 is provided on the base 1, and the controllable magnetic seat 4 is installed on the base 1, and the base 1 is installed through the controllable magnetic seat 4.

[0034] Reference Figure 2 The base 1 includes a bottom plate 12 and a base 13, which are integrally formed. The bottom plate 12 is in a rectangular plate shape as a whole. A slot 14 is provided on the side of the bottom plate 12 away from the base 13 in the thickness direction. An insert strip 41 is provided on the controllable magnetic seat 4. The insert strip 41 on the controllable magnetic seat 4 is plugged and matched with the slot 14 on the base 1, so that the convenience of installing the controllable magnetic seat 4 on the base 1 is improved. When in use, the controllable magnetic seat 4 is opened so that the base 1 can be quickly installed.

[0035] The adjustment assembly 2 includes a rotating column 21, which is rotatably mounted on the base 1, and a first thread 211 is formed on the rotating column 21, a guide groove 15 is provided on the base 13, and a connecting block 31 is provided on the clamping block 3, one end of the connecting block 31 is connected to the clamping block 3, and the other end passes through the guide groove 15 and extends to one side of the rotating column 21, and a second thread 32 is formed on the side of the connecting block 31 close to the rotating column 21, and the first thread 211 on the rotating column 21 is threadedly matched with the second thread 32 on the connecting block 31. When in use, the rotating column 21 rotates on the base 1, and since the rotating column 21 and the connecting block 31 are threadedly matched, the convenience of moving the clamping block 3 on the base 1 is improved.

[0036] Reference Figure 3 Furthermore, a bearing 16 is provided on the base 1, and the bearing 16 is installed on the base 1. One end of the rotating shaft passes through the bearing 16, and the rotating shaft and the bearing 16 are connected by an interference fit, thereby improving the convenience of rotating the rotating column 21.

[0037] In addition, in order to prevent the clamping block 3 from shaking during the movement on the base 1, a mounting groove 17 is provided on the base 1. Two mounting grooves 17 are provided on the side of the base 1 close to the guide groove 15. Support springs 171 are provided in both mounting grooves 17. The support springs 171 are embedded in the corresponding mounting grooves 17, and a support plate 172 is provided at one end of the support spring 171. The support plate 172 is connected to the support spring 171, and one side of the support plate 172 contacts the connecting column, and is pressed tightly between the connecting block 31 and the base 1 through the support spring 171. When the clamping block 3 moves on the base 1 driven by the rotating column 21, the support spring 171 is in a compressed state. At this time, the reaction force of the support spring 171 pushes the clamping block 3 to the side away from the base 1, thereby preventing the clamping block 3 from shaking during the movement.

[0038] In addition, in order to improve the stability of the clamping block 3 moving on the base 1, a limiting groove 18 is provided on the base 1, and two limiting grooves 18 are provided on the base 1 at intervals, and the two limiting grooves 18 are located on both sides of the guide groove 15. A limiting block 33 is provided on the clamping block 3, one end of the limiting block 33 is connected to the clamping block 3, and the other end is slidably matched with the limiting groove 18, thereby improving the stability of the sliding of the clamping block 3 on the base 1.

[0039] A rubber pad 19 is provided on one side where the base 1 and the clamp block 3 are close to each other. The rubber pad 19 is bonded to the base 1 and the clamp block 3. When the base 1 and the clamp block 3 clamp the workpiece, the rubber pad 19 is deformed. Due to the deformation of the rubber pad 19, on the one hand, the rubber pad 19 can improve the stability of the clamping of the workpiece. On the other hand, the rubber pad 19 can also prevent scratches between the workpiece and the clamp block 3 and the base 1, thereby protecting the workpiece.

[0040] The implementation principle of a workpiece clamping mechanism in an embodiment of the present application is as follows: a controllable magnetic seat 4 is inserted into a slot 14 of a base 1 through an insertion strip 41, and then the base 1 is installed through the controllable magnetic seat 4. After the base 1 is installed, the workpiece is placed in the clamping groove 11, and then the rotating column 21 is adjusted. As the rotating column 21 rotates, the clamping block 3 moves toward the side close to the base 1. At this time, the support spring 171 is in a compressed state. During the movement of the clamping block 3, the limiting groove 18 limits the clamping block 3. As the clamping block 3 and the base 1 clamp the workpiece, the rubber pad 19 is deformed. When the workpiece needs to be released, the rotating column 21 is adjusted in the opposite direction. At this time, the clamping block 3 moves toward the side away from the base 1, and then the workpiece is taken out of the clamping groove 11.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
