Technical Field

[0001] This invention relates to the field of workpiece clamping technology, and in particular to a part clamping device. Background Technology

[0002] In the existing technology, some products usually need to be clamped during use. However, currently, the workpieces are usually clamped manually. When clamping manually, it is impossible to guarantee that the clamping force of each workpiece is consistent. Therefore, not all workpieces can achieve good results during use. Furthermore, since the clamping force of each manual operation cannot be completely consistent, there may be multiple different clamping forces for a batch of products, which may also lead to the problem of defective workpieces being clamped.

[0003] In view of the above, it is necessary to improve the existing workpiece clamping method so that it can meet the current need to eliminate the need for manual clamping of products. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the current method of manually clamping workpieces is not very universal and is prone to many problems during use. The most direct problem is that the clamping force is insufficient, which leads to the workpiece being unusable later. Therefore, based on the existing technology, we have designed a device to clamp workpieces, which is easy to operate, can maintain a consistent clamping force for each workpiece, and is convenient for people to use.

[0026] This technical solution mainly includes an X-axis clamping device 2, a Y-axis moving device 3, and a Z-axis clamping device. The workpiece 35 is clamped by combining the three directions, which provides comprehensive clamping, is convenient to use, and is simple to operate. The above three clamping devices are also the main innovations of this invention. The structure and working principle of this invention will be described in detail below.

[0027] like Figure 1-5 As shown, a support platform 1 is provided below the X-axis clamping device 2 and the Y-axis moving device 3 to provide support. The X-axis clamping device 2 and the Y-axis moving device 3 are perpendicular to each other. The X-axis clamping device 2 includes a first pushing device 21 and a first locking device 22 disposed on the first pushing device 21. The first pushing device 21 includes a base plate 211, a first support plate 212 disposed on the base plate 211, a first electric cylinder 213 disposed on the first support plate 212, a first push rod connected to the first electric cylinder 213, and a moving plate 214 connected to the first push rod. The base plate 211 is fixedly installed on the support platform 1, and the first support plate 212 is fixedly installed on the base plate 211, mainly providing support. The first electric cylinder 213 is fixedly installed on the first support plate 212. The first push rod is connected to the first electric cylinder 213, and the first electric cylinder 213 can drive the first push rod to move. The moving plate 214 is connected to the first push rod and can move with the first push rod. The first push rod moves along with the moving plate 214. To make the movement of the moving plate 214 more stable, first connecting plates 215 are provided on the lower left and right sides of the moving plate 214. A first slide rail 216 is slidably connected to the lower part of the first connecting plate 215. That is, under the action of the first push rod, the moving plate 214 can slide on the first slide rail 216 through the first connecting plate 215. In order to facilitate the subsequent clamping of the workpiece 35 by the equipment, a first locking device 22 is installed on the first pushing device 21. The first locking device 22 includes a first motor 221, a first rotating shaft 222 connected to the first motor 221, and a top block 223 connected to the first rotating shaft 222. The first motor 221 is fixedly installed on the moving plate 214. The first motor 221 can drive the first rotating shaft 222 to move. The top block 223 can move with the movement of the first rotating shaft 222, thereby locking the workpiece 35 on the fixture.

[0028] Below is the Y-axis moving device 3, which includes a second electric cylinder 31, a second push rod connected to the second electric cylinder 31, a receiving plate 32 fixedly connected to the second push rod, a second support plate 33 disposed above the receiving plate 32, and a fixing clamp 34 disposed above the second support plate 33. The second electric cylinder 31 can drive the second push rod to move in the Y direction, and the receiving plate 32 also moves with the movement of the second push rod. The second support plate 33 is fixedly connected to the receiving plate 32 and can move with the movement of the receiving plate 32. The fixing clamp 34 is fixedly installed on the second support plate 33. The fixture 34 is hollow and is used to place the workpiece 35. During normal use, the fixture 34 can be replaced according to the size of the commonly used workpiece 35. The X-axis clamping device 2 can lock the side of the fixture 34, so that the workpiece 35 can be stably fixed in the fixture 34. The second support plate 33 has snap-fit ​​plates on the left and right sides below it. The snap-fit ​​plates are provided with a second slide rail below them. Since the second electric cylinder 31 can indirectly drive the support plate 32 to move, the snap-fit ​​plates can also slide on the second slide rail with the support plate 32, so that people can place the workpiece 35 in the fixture 34 in a safe position.

[0029] In order to effectively clamp the workpiece 35 in the Y-axis direction, top plates 36 are provided on both sides of the fixed fixture 34 in the Y-axis direction. A first fixing plate 37 is fixedly installed on one of the top plates 36 and is fixedly installed on the second support plate 33. The other top plate 36 is installed on the fixed fixture 34 by screws 38. The locking in the Y-axis direction is achieved by tightening the screws 38.

[0030] Finally, there is the Z-axis clamping device, which includes a telescopic rod 41 mounted on the support platform 1, a second connecting plate 42 mounted on the telescopic rod 41, a second fixing plate 43 located above the second connecting plate 42, a third electric cylinder 44 mounted on the second fixing plate 43, a third push rod connected to the third electric cylinder 44, a second motor 45 mounted on the second connecting plate 42, a second rotating shaft 46 connected to the second motor 45, and a locking block 47 connected to the second rotating shaft 46. There are four telescopic rods 41, and their connecting lines can form a cuboid. The X-axis clamping device 2 is located between two adjacent telescopic rods 41 in the Y-axis direction. The lower end of each telescopic rod 41 is fixedly mounted on the support platform 1. The second connecting plate 42 is slidably mounted on the telescopic rod 41. The second fixing plate 43 is fixedly mounted on the top end of the telescopic rod 41. The third electric cylinder 44 is fixedly mounted on the second fixing plate 43. The third electric cylinder 44 can drive the third push rod to move up and down. The third push rod is fixedly connected to the second connecting plate 42. That is, when the third push rod moves up and down, it can drive the second connecting plate 42 to move up and down on the telescopic rod 41. The second motor 45 is fixedly installed on the second connecting plate 42. The second motor 45 can drive the second rotating shaft 46 to rotate. The locking block 47 is connected to the second rotating shaft 46. When the second rotating shaft 46 rotates, it can drive the locking block 47 to rotate, thereby fastening the workpiece 35 to the fixed clamp 34. That is, during operation, the third electric cylinder 44 first drives the third push rod to move, and then indirectly causes the second connecting plate 42 to move until the second rotating shaft 46 moves above the workpiece 35. Then, the second motor 45 is activated, which causes the second rotating shaft 46 to rotate. The locking block 47 rotates with the second rotating shaft 46, thereby squeezing the workpiece 35, so that the workpiece 35 can be fastened to the fixed clamp 34.

[0031] In order to make this technical solution more intelligent and reduce the intensity of manual operation, sensors 48 are respectively provided on one side of the two diagonally placed telescopic rods 41 to detect whether the workpiece 35 has moved into place, so that the X-axis clamping device 2 can clamp it, instead of judging whether the position is in place by eye.

[0032] The device is also equipped with a protective frame 5 on the outside, which provides a certain degree of safety for human operation.

[0033] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
