Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and more specifically, particularly relates to a clamping device for a milling machine. Background Art

[0002] In the machinery manufacturing industry, the milling machine is a common machining equipment. In the process of processing pliers, a horizontal milling machine is needed to cut the outer end surface of the pliers handle. However, the existing milling machine still has some shortcomings when clamping the pliers handle.

[0003] For example, the utility model patent with application number 202223292525.6 discloses a clamping device for a boring and milling machine, including a support frame, the upper end of the support frame is fixedly connected to a bed, the top of the bed is fixedly connected to a cover plate, the upper surface of the cover plate is provided with a loading platform, both sides of the loading platform are fixedly connected to fixed plates, an inner groove is provided on the left side of the fixed plate, and a second fixed track is welded to the inner wall of the inner groove. In this type of clamping device for a boring and milling machine, when the material to be constructed is placed on the loading platform, the clamping devices on the fixed plates on both sides of the loading platform can be adjusted according to the size and contour of the material, and the rotating motor on the fixed frame drives the rotating wheel to move forward and backward, thereby driving the movable caliper device on the rotating wheel to adjust the spatial position, and the movable caliper can apply inward pressure to the material to be processed from eight directions, so that the material will not shake when it is fully clamped for processing, so that the processing operation can be completed smoothly.

[0004] Based on the search of the above patents and combined with the current usage of milling machine clamping fixtures, the current milling machine clamping fixtures lack protective devices for workers. When the worker places the clamp handle between the clamps, the worker's fingers are also located between the two clamps. At this time, the worker will pinch his fingers after starting the hydraulic cylinder, resulting in work-related accidents. In addition, when the tool is cutting the clamp handle, some iron chips will fly outward, posing a safety threat to the workers next to the machine. Utility Model Content

[0005] In order to solve the above technical problems at least to a certain extent, the utility model provides a clamping device for a milling machine.

[0006] The purpose and effect of a clamping device for a milling machine of the utility model are achieved by the following specific technical means: A clamping device for a milling machine comprises a workbench;

[0007] Four supporting legs are fixedly installed on the lower end surface of the workbench, and a pad with a circular plate structure is fixedly installed on the lower end of the supporting legs;

[0011] The fixed frame has a U-shaped main body, is located at the front end of the sliding block, and has a left-right protective frame fixedly installed inside the fixed frame.

[0012] Furthermore, the upper end surface of the workbench is provided with two transverse track grooves, and the front end surface of the workbench is fixedly mounted with two hooks.

[0013] Furthermore, two limit blocks are fixedly mounted on the lower end surface of the sliding block, and the two limit blocks are slidably mounted in the two transverse track grooves respectively, and four second connecting holes are opened on the left end surface of the sliding block.

[0014] Furthermore, the front end surface of the sliding block is provided with two fixing holes, the fixing holes are provided with threads, and the surface of the vertical plate of the fixing frame is evenly provided with four through holes.

[0015] Furthermore, the inner diameter of the fixing hole is the same as the inner diameter of the through hole, the distance between two adjacent through holes is the same as the distance between two fixing holes, and the fixing frame and the sliding block are connected by bolts.

[0016] Furthermore, a groove is provided on one side of the left end of the protection frame, and a protection net is installed inside the protection frame.
