Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a clamping and fixing device for punching machines. Background Art

[0002] The product has a flat appearance and a large width-to-thickness ratio. It can be arbitrarily cut, bent, stamped, welded, and made into various finished components. It is flexible and convenient to use. The earliest board was a solid wood board used by carpenters to make furniture or other living facilities. With the development of science and technology, the definition of board is very broad. There are boards of different materials in furniture manufacturing, construction, and processing industries. Boards need to be punched according to production and processing needs. The board needs to be fixed during the punching process to prevent the board from moving during the punching process. The existing clamping mechanism is difficult to maintain and is not convenient for promotion and implementation.

[0003] For example, Chinese patent announcement No. CN211027815U discloses a clamping mechanism for a sheet punching machine. When in use, the sheet is placed on a placement seat. The hydraulic rod is started, and the hydraulic rod contracts to make the connecting frame move inward, and the blocking rod contacts the side of the placement seat. The support frame rotates downward, and the clamping rod is clamped at both ends of the sheet, so that the sheet is fixed. After the processing is completed, the hydraulic rod extends, the connecting frame moves to both sides, and the blocking rod is disengaged from the side of the placement seat. Under the action of , the support frame rotates upward. The sheet can be taken out, and the setting of the ball makes the sliding block slide more smoothly. It has the characteristics of simple structure, large operating space, reliable clamping, smooth sliding, and easy promotion and implementation.

[0004] However, the clamping mechanism of the sheet punching machine in the above application clamps and fixes the sheet as a whole. When it is necessary to perform interval punching on the surface of the sheet, the sheet needs to be moved repeatedly, which is a cumbersome operation. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a clamping and fixing device for a punching machine. Utility Model Content

[0006] The purpose of the utility model is to provide a clamping and fixing device for a punching machine to solve the problem that the clamping mechanism of the plate punching machine proposed in the above background technology clamps and fixes the plate as a whole, and when it is necessary to punch holes at intervals on the surface of the plate, the plate needs to be moved repeatedly, which is a cumbersome operation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping and fixing device for a punching machine, comprising a processing table and supporting legs, wherein the four supporting legs are respectively fixedly connected to the four corners of the lower surface of the processing table, and the upper surface of the processing table is provided with a clamping and fixing device, a pushing device and a punching device.

[0008] The clamping and fixing device includes a bidirectional motor, a fixed bearing, a transmission member, a connecting rod, a U-shaped frame, and a roller. The bidirectional motor is installed at the center of the lower surface of the processing table. The two fixed bearings are fixedly connected to the front and rear sides of the lower surface of the processing table respectively. The two groups of transmission members are respectively connected to the output ends of the bidirectional motor, and the outer ends thereof are rotatably connected to the inside of the fixed bearings. The two connecting rods are respectively fixedly connected to the top of the transmission member, and the two U-shaped frames are respectively fixedly connected to the top of the connecting rods. The two groups of rollers are respectively equidistantly rotatably connected to the inside of the U-shaped frame.

[0009] A further improvement is that limiting grooves are respectively provided on the front and rear sides of the upper surface of the processing table, and the connecting rod is slidably connected to the inside of the limiting groove. When facing plates of different widths, the bidirectional motor is started to drive the screw in the transmission part to rotate inside the fixed bearing, thereby driving the threaded sleeve on the screw and the connecting rod on its top to slide relative to each other along the inside of the limiting groove, thereby driving the U-shaped frame to slide relative to each other until the rollers inside the U-shaped frame clamp and fix the plate from both sides to prevent the plate from being skewed when moving during loading.

[0010] A further improvement is that rubber pads are installed on the outside of the rollers. The rubber pads prevent the rolling of the rollers from scratching the side walls of the plates when the plates are clamped, and play a certain protective role.

[0011] A further improvement is that the pushing device includes an electric guide rail, a guide rail seat, a connecting beam, and a pushing plate. The two electric guide rails are respectively installed at the front and rear ends of the upper surface of the processing table. The two guide rail seats are respectively slidably connected to the electric guide rails. The connecting beam is fixedly connected between the two guide rail seats. The pushing plate is fixedly connected to the bottom of the connecting beam. The guide rail seat is driven to slide to the right on the electric guide rail, thereby driving the connecting beam and the pushing plate at its bottom to push the plate to the right for punching processing. No manpower is required to load the material, and it is more convenient and quick to use.

[0012] A further improvement is that the punching device comprises a punching unit and a fixing unit.

[0013] The punching unit includes a support frame, an electric lifting rod, a punching plate, and a punching drill bit. The support frame is fixedly connected to the right side of the upper surface of the processing table, the electric lifting rod is installed at the bottom of the support frame, the punching plate is fixedly connected to the bottom of the electric lifting rod, and several punching drill bits are equidistantly installed at the bottom of the punching plate. The electric lifting rod is driven to move downward, thereby pushing the punching plate downward, and then the punching drill bit at its bottom is used to punch the plate.

[0014] A further improvement is that the fixing unit includes a sliding sleeve, a sliding rod, a fixing plate, and an extrusion spring. The two sliding sleeves are respectively fixedly connected to the front and rear ends of the punching plate, the two sliding rods are respectively slidably connected to the inside of the sliding sleeve, the fixing plate is fixedly connected to the bottom of the sliding rod, and the two extrusion springs are respectively fixedly connected between the punching plate and the fixing plate, and are installed around the outside of the sliding sleeve.

[0015] A further improvement is that a through hole corresponding vertically to the punching drill bit is penetrated through the upper surface of the fixed plate. Before the punching drill bit punches the hole, the fixed plate first contacts the surface of the plate. When the punching drill bit continues to move downward to punch the hole, the fixed plate pushes the sliding rod to slide upward inside the sliding sleeve and compresses the extrusion spring, thereby pressing and fixing the plate to prevent the plate from shaking.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The clamping and fixing device of the punching machine, when facing plates of different widths, starts the bidirectional motor to drive the screw in the transmission part to rotate inside the fixed bearing, thereby driving the threaded sleeve on the screw and the connecting rod on its top to slide relatively along the inside of the limiting slide groove, thereby driving the U-shaped frame to slide relatively, until the rollers inside the U-shaped frame clamp and fix the plate from both sides to prevent the plate from being skewed when the material is loaded and moved.

[0018] 2. The punching machine uses a clamping and fixing device to drive the guide rail seat to slide to the right on the electric guide rail, thereby driving the push plate connecting the crossbeam and its bottom to push the plate to the right for punching processing. No manpower is required to load the material, which is more convenient and quick to use. BRIEF DESCRIPTION OF THE DRAWINGS
