Description

Technical Field

[0001] The utility model belongs to the technical field of plate roller production and processing, in particular to a clamping device for a welding and plugging machine. Background Art

[0002] The plate roller is also called a steel roller, which is divided into hollow rollers and solid rollers, shaft rollers and non-shaft rollers. It is generally used for plate making. The surface of the roller is copper-plated, and the pattern is engraved by a gravure electronic engraving machine, and then plated with a layer of chrome. After it is completed, it is delivered to the printing factory and is often used for printing plastic packaging. Before the plate roller plug leaves the factory, it needs to be fixed for subsequent processing.

[0003] The existing open patent (publication number CN 218745768 U) discloses a fixing device for processing a plate roller plug, including a bottom plate, a fixing mechanism is arranged on the top of the bottom plate, and the fixing mechanism includes a back plate. The fixing device for processing a plate roller plug controls the motor to drive the rotating shaft to rotate, so that the disc A and the disc B rotate, so that the lower connecting rod and the upper connecting rod swing, and drive the hollow sliding rod to swing, the sliding shaft slides on the inner wall of the hollow sliding rod, and the square rod moves horizontally under the limit of the column through the U-shaped block, so as to control the distance between the first clamping plate and the first baffle plate, so that the two sides of the plate roller plug are clamped; the threaded rod is rotated, the slide groove limits the slide column, so that the slide column moves along the inner wall of the slide groove, so as to control the distance between the second clamping plate and the second baffle plate, so that the front and back of the plate roller plug are clamped, so that the four sides of the plate roller plug are clamped; the disassembly mechanism replaces the first baffle plate and the second baffle plate with baffle plates of different thicknesses, so as to adapt to plate roller plugs of different diameter specifications.

[0004] However, when the above device is actually used, the structures are relatively scattered and the linkage effect is poor, resulting in poor clamping effect of the clamping and positioning device and low energy consumption utilization, thereby reducing the overall practicality. To this end, we provide a clamping device for a welding plugging machine to solve the above problems. Utility Model Content

[0006] The utility model discloses a clamping device for a welding plugging machine, comprising a clamping assembly for clamping and positioning a plate roller body in welding plugging operation; the clamping assembly comprises a bottom plate, a guide rail fixed to the side surface of the bottom plate, a guide block movably arranged inside the guide rail, a bracket fixed to the upper side surface of the guide block, and a clamping component arranged on one side of the bracket;

[0007] The clamping component comprises a cylinder fixed at the bottom of the bracket, a beam fixed at the telescopic end of the cylinder, a transmission arm movably arranged at the end of the beam, and a clamping block movably arranged at the end of the transmission arm.

[0008] The utility model is further configured that the inner side of the clamping block is curved in an arc shape, and the clamping block is arranged in close contact with the peripheral side of the plate roller body.

[0009] The utility model is further configured that the upper end of the transmission arm is movably connected to the side surface of the bracket via a shaft.

[0010] The utility model is further configured that the bracket is an L-shaped structure, and an arc-shaped notch is provided at the middle position of the upper part of the bracket.

[0011] The utility model is further configured such that the bottom plate is a hollow structure, and the bottom plate is arranged below the working end of the welding and plugging machine.

[0012] The utility model is further configured that positioning holes are equidistantly arranged on one side of the guide rail, the positioning holes are matched with external knobs, and the guide block is fixed to the guide rail via the knob.

[0013] The utility model has the following beneficial effects:

[0014] The utility model clamps and fixes the plate roller body by arranging two clamping assemblies arranged in parallel, so as to assist the plate roller body in subsequent welding and plugging operations. The clamping assembly has a simple structure and is convenient to operate, and is suitable for clamping and fixing plate roller bodies of different diameters. The various structures are closely linked to improve the clamping stability of the plate roller body, and has great practical value.

[0015] Specifically, when clamping the plate roller body, first control the transmission arm to be in the maximum expansion state, then place the plate roller body into the transmission arm, and start the cylinder under the control of the external control end. The telescopic end of the cylinder drives the movement of the crossbeam, and under the traction and pushing action of the crossbeam, the transmission arms are driven to approach each other, so that the clamping block contacts the peripheral side of the plate roller body, thereby completing the clamping of the plate roller body.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-3 The utility model is a clamping device for a welding plugging machine, comprising a clamping assembly 1 for clamping and positioning a plate roller body 2 in welding plugging operation; the clamping assembly 1 comprises a bottom plate 11, a guide rail 12 fixed to the upper side of the bottom plate 11, a guide block 13 movably arranged inside the guide rail 12, a bracket 14 fixed to the upper side of the guide block 13, and a clamping component arranged on one side of the bracket 14; the clamping component comprises a cylinder 17 fixed to the bottom of the bracket 14, a crossbeam 18 fixed to the telescopic end of the cylinder 17, a transmission arm 15 movably arranged at the end of the crossbeam 18, and a clamping block 16 movably arranged at the end of the transmission arm 15;

[0026] It needs to be further explained that in the clamping device for the welding and plugging machine involved in the present application, two parallel clamping assemblies 1 are set to clamp and fix the plate roller body 2, so as to assist the plate roller body 2 in performing subsequent welding and plugging operations. The clamping assembly 1 has a simple structure and is easy to operate. It is suitable for clamping and fixing plate roller bodies 2 of different diameters, and has great practical value. Specifically, when clamping the plate roller body 2, the transmission arm 15 is first controlled to be in the maximum expansion state, and then the plate roller body 2 is placed in the transmission arm 15. Under the control of the external control end, the cylinder 17 is started, and the telescopic end of the cylinder 17 drives the movement of the crossbeam 18. Under the traction and pushing action of the crossbeam 18, the transmission arms 15 are driven to approach each other, so that the clamping block 16 is in contact with the peripheral side of the plate roller body 2 to complete the clamping of the plate roller body 2.

[0027] The inner side of the clamping block 16 is curved and arranged in an arc shape, and the clamping block 16 is arranged close to the peripheral side of the plate roller body 2, and the upper end of the transmission arm 15 is movably connected to the side of the bracket 14 through a shaft;

[0028] It should be further explained that the arc-shaped bend on the inner side of the clamping block 16 is used to increase the contact area between the clamping block 16 and the peripheral side of the plate roller body 2, thereby improving the clamping stability of the clamping assembly 1. In actual use, protective pads and other structures can be selectively installed. After the upper part of the transmission arm 15 is movably connected to the bracket 14 via a shaft, under the action of external force, its end rotates along the shaft, thereby driving the clamping block 16 movably connected at its end to move closer or farther away from each other, thereby clamping and releasing the plate roller body 2, and the transmission arm 15 cannot be separated from the bracket 14 during the movement.

[0029] The bracket 14 as a supporting structure is an L-shaped structure, and an arc-shaped notch is provided in the middle position of the upper part of the bracket 14. The bottom plate 11 is a hollow structure, and the bottom plate 11 is provided below the working end of the welding plugging machine. Positioning holes are equidistantly provided on one side of the guide rail 12, and the positioning holes are matched with the external knobs. The guide block 13 is fixed to the guide rail 12 via the knobs.

[0030] It should be further explained that the vertical surface of the L-shaped bracket 14 is used for the movable installation of the transmission arm 15, and the horizontal surface of the bracket 14 is used for the installation and fixation of the cylinder 17. The arc-shaped notch in the middle position facilitates the subsequent limited placement of the registration roller body 2.

[0031] The clamping device is used to cooperate with the welding and plugging operation of the welding and plugging machine. Therefore, the bottom plate 11 is used as the base structure of the clamping device to determine the position of the clamping device. During actual installation, the bottom plate 11 is installed below the welding and plugging machine. Its hollow structure is set to prevent the residue from falling during the welding and plugging operation.

[0032] The guide rail 12 supports the bracket 14 through the guide block 13. At the same time, under the restriction of the guide rail 12, the guide block 13 moves linearly along the guide rail 12 under manual adjustment to adjust the distance between the two clamping assemblies 1. After the distance adjustment of the two clamping assemblies 1 is completed, the knob is tightened to fix the position of the guide block 13 relative to the guide rail 12, thereby achieving the position fixation of the clamping assembly 1.
