Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a workpiece support device for preventing offset. Background Technology
[0002] Fixtures are essential in machining, with common fixtures such as vises and chucks used to clamp and position the workpiece. However, existing clamping methods are limited and can only hold a single workpiece in a fixed orientation. They cannot simultaneously clamp multiple points on the same side of the workpiece, and they cannot handle workpiece displacement during clamping. Utility Model Content
[0003] Those skilled in the art have provided a workpiece support device to prevent displacement, in order to solve the problems mentioned in the background art.
[0004] To solve the above technical problems, this utility model provides a workpiece support device for preventing displacement, including a base plate. The upper surface of the base plate has two slots, which are symmetrically arranged. Several first pressure sensors are fixedly installed at the bottom of the slots. The pressure at different positions on the bottom of the workpiece is detected by the several first pressure sensors in the two slots, thereby adjusting the pressure of different cylinders. A support fixture assembly is fixedly installed in the middle of the upper surface of the base plate, and several workpieces are clamped at the upper end of the support fixture assembly.
[0005] The support fixture assembly includes a support column, a support base plate, cylinders, rubber pads, pressure plates, a long plate, a bayonet, threaded holes, threaded bolts, and a second pressure sensor. The support column is bolted to the upper end of the base plate, and the support base plate is fixedly installed on the upper end of the support column. Cylinders are installed at the four corners of the lower end face of the support base plate, and the cylinders are bolted to the support base plate. The second pressure sensor is fixedly installed at the four corners of the bottom of the pressure plate. By placing the workpiece on the left and right sides of the upper end face of the support base plate, the cylinders are retracted by an external controller. A long plate is placed between two corresponding cylinders and engages with the cylinder's telescopic shaft through a bayonet, so that the two pressure plates apply pressure to the long plate, and the long plate simultaneously applies the pressure to multiple workpieces, ensuring a constant applied pressure, thereby stably clamping the workpieces on the support base plate.
[0006] In a preferred embodiment: the lower left and right sides of the base plate are fixedly installed with bolts to the leveling plate, and several reinforcing plates are provided between the two leveling plates for fixing, thereby strengthening the stability of the leveling plate for the installation of the support clamp assembly.
[0007] In a preferred embodiment: the upper telescopic shaft of the cylinder moves through the support base plate, and a threaded hole is provided at the top of the upper telescopic shaft of the cylinder.
[0008] In a preferred embodiment: a threaded bolt is provided in the threaded hole, and the threaded bolt is fixedly installed in the middle of the lower end face of the pressure plate.
[0009] In a preferred embodiment: two cylinders corresponding to each other are arranged as a group, and a long plate is provided between the two cylinders in each group. Two slots are opened on the side of the long plate, and the slots are corresponding to the telescopic shafts of the cylinders. By using the pressure of the long plate, the pressure applied by the two corresponding cylinders is kept synchronous.
[0010] In a preferred embodiment: a plurality of rubber pads are fixedly installed in the middle of the upper end face of the support plate. The elastic deformation of the rubber pads isolates the workpiece from direct contact with the support plate, reduces friction between the two, and thus prevents damage to the workpiece.
[0011] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0012] 1. When this utility model is used, an external control unit is used to control the cylinder to retract. A long plate is installed between two corresponding cylinders through a bayonet and the cylinder's telescopic shaft. This allows two pressure plates to apply pressure to the long plate, and the long plate to apply the pressure to multiple workpieces simultaneously, ensuring that the applied pressure is constant. This allows multiple workpieces to be stably clamped on the support plate, ensuring the synchronicity of clamping multiple workpieces and providing a good foundation for the subsequent synchronous processing of multiple workpieces.
[0013] 2. When this utility model is used, the slot will limit the two ends of the workpiece to prevent the workpiece from tilting to both sides due to pressure in the middle. At the same time, several first pressure sensors are used to detect the pressure at different positions on the bottom of the workpiece. Combined with the pressure data of the second pressure sensor on the pressure plate, the pressure of different cylinders is adjusted to reduce the workpiece from shifting. Attached Figure Description

[0023] Please see Figures 1-4 This embodiment provides a workpiece support device to prevent displacement, including a base plate 1. The lower left and right sides of the base plate 1 are fixedly installed with equal-level plates 6 by bolts. Several reinforcing plates 2 are set between the two equal-level plates 6 for fixation, thereby strengthening the installation stability of the equal-level plates 6 on the support fixture assembly 3. Two slots 5 are opened on the upper end surface of the base plate 1. The two slots 5 are arranged symmetrically on the left and right. Several first pressure sensors 7 are fixedly installed at the bottom of the slots 5. The pressure on different positions of the bottom of the workpiece 4 is detected by the several first pressure sensors 7 in the two slots 5, thereby adjusting the pressure of different cylinders 33. The support fixture assembly 3 is fixedly installed in the middle of the upper end surface of the base plate 1. Several workpieces 4 are clamped at the upper end of the support fixture assembly 3.
[0024] The support fixture assembly 3 includes a support column 31, a support base plate 32, cylinders 33, rubber pads 34, pressure plates 35, long plates 36, bayonet 37, threaded holes 38, threaded bolts 39, and a second pressure sensor 310. The support column 31 is bolted to the upper end of the base plate 1. The support base plate 32 is fixedly mounted on the upper end of the support column 31. Cylinders 33 are installed at the four corners of the lower end face of the support base plate 32, and are bolted to the support base plate 32. The upper telescopic shaft of the cylinder 33 moves through the support base plate 32. A threaded hole 38 is opened at the top of the upper telescopic shaft of the cylinder 33, and a threaded bolt 39 is installed inside the threaded hole 38. The threaded bolt 39 is fixedly mounted in the middle of the lower end face of the pressure plate 35. A second pressure sensor 310 is fixedly mounted at the four corners of the bottom of the pressure plate 35. Two cylinders 33 corresponding to each other are arranged as a group, and a bayonet is provided between each group of two cylinders 33. The long plate 36 has two latches 37 on its side, which correspond to the telescopic shafts of the cylinders 33. The pressure of the long plate 36 keeps the pressure of the two corresponding cylinders 33 synchronized. Several rubber pads 34 are fixedly installed in the middle of the upper surface of the support plate 32. The elastic deformation of the rubber pads 34 isolates the workpiece 4 from direct contact with the support plate 32, reducing friction between them and preventing damage to the workpiece 4. By placing the workpiece 4 on the left and right sides of the upper surface of the support plate 32, the cylinders 33 are retracted by an external controller. The long plate 36 is placed between the two corresponding cylinders 33 through the latches 37 and the telescopic shafts of the cylinders 33. This allows the two pressure plates 35 to apply pressure to the long plate 36, and the long plate 36 applies the pressure to multiple workpieces 4 synchronously, ensuring a constant pressure and thus stably clamping the workpiece 4 on the support plate 32.
[0025] The working principle of this utility model is as follows:
[0026] In use, the workpiece 4 is placed on the left and right sides of the upper surface of the support plate 32, and the two ends of the workpiece 4 are engaged into the slots 5. The external controller controls the cylinder 33 to retract. A long plate 36 is placed between the two corresponding cylinders 33 through the slot 37 and the telescopic shaft of the cylinder 33, so that the two pressure plates 35 apply pressure to the long plate 36, and the long plate 36 applies the pressure to multiple workpieces 4 simultaneously, ensuring that the applied pressure is constant. This allows multiple workpieces 4 to be clamped synchronously and stably on the support plate 32. At this time, the slots 5 limit the two ends of the workpiece 4 to prevent the workpiece 4 from tilting to the sides due to pressure in the middle. At the same time, several first pressure sensors 7 detect the pressure at different positions on the bottom of the workpiece 4. Combined with the pressure data of the second pressure sensor 310 on the pressure plate 35, the pressure of different cylinders 33 is adjusted to reduce the displacement of the workpiece 4.
[0027] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
