[0002] With the rapid progress of society and the booming economy, people have increasing requirements for the comfort and convenience of travel. Locomotive interior parts refer to various parts and decorations installed inside the locomotive to improve people's driving comfort as well as the aesthetics and functionality of the vehicle interior. The production and processing of locomotive interior parts requires a series of processes such as cutting, punching, and grinding, and these operations require a device that can firmly clamp the locomotive interior material.

[0003] In the prior art, general locomotive interior material clamping decoration uses two sets of clamping plates to extrude and clamp the interior material to avoid displacement of the interior material during processing, so as to improve the quality of the processed product. However, there are many types of locomotive interior materials, including not only square materials but also cylindrical materials with curved surfaces. The clamping of cylindrical materials is unstable, and the materials are prone to slide and displace during subsequent processing, thereby reducing the processing quality. At the same time, the existing clamping device usually squeezes and displaces the clamping plates by manually twisting bolts, thereby completing the clamping operation of the two sets of clamping plates close to each other, which increases the workload of the staff and reduces work efficiency. Therefore, a locomotive interior material clamping device is proposed to solve the above problems. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a material clamping device for locomotive interior parts, comprising a base 1, a mounting hole 2 is provided on the top of the base 1 for conveniently mounting the base 1 on an external platform by bolts, thereby increasing the stability of the base 1 during work and improving the stability of material clamping, a workbench 3 is fixedly connected to the top of the base 1, a material clamping mechanism is arranged inside the workbench 3, the material clamping mechanism comprises a clamping plate 4 for clamping materials, the number of the clamping plates 4 is set to two groups, a rotating mechanism is arranged on the side where the two groups of clamping plates 4 are close to each other, the bottoms of the two groups of clamping plates 4 are fixedly connected to a moving block 5 arranged in a cubic shape, and a groove 6 is arranged on the top surface of the workbench 3.

[0031] Reference Figure 2 - Figure 3 The clamping mechanism also includes a guide rod 7 arranged in a horizontal state, and the guide rod 7 is fixedly mounted on the inner wall of the groove 6. The guide rod 7 guides the displacement direction of the moving block 5, so that the moving block 5 makes a more precise linear motion in the axial direction of the guide rod 7. The moving block 5 is slidably mounted on the circumferential surface of the guide rod 7. The sliding direction of the moving block 5 is left and right sliding. The moving block 5 is slidably mounted on the inner wall of the groove 6. The clamping mechanism also includes a connecting rod 8, which is inclined, one end of the connecting rod 8 is hinged to the bottom of the moving block 5, and the other end of the connecting rod 8 is hinged to a slider 9. The clamping mechanism also includes a connecting rod 2 10, which is inclined, the length of the connecting rod 1 8 is equal to the length of the connecting rod 2 10, one end of the connecting rod 2 10 is hinged to the surface of the slider 9, and the other end of the connecting rod 2 10 is hinged to the inner wall of the workbench 3.

[0032] Reference Figure 2 The clamping mechanism also includes a linear stepper motor 11, which is fixedly mounted on the inner wall of the workbench 3. The model of the linear stepper motor 11 is 20DAM-L. The linear stepper motor 11 can accurately control the moving distance of its output shaft, and can control the displacement distance of its output shaft according to the size of the interior material of different models. The control is more refined, and it is separated from improving the stability of clamping. The clamping mechanism also includes a transmission rod 12 set as a cylinder. The transmission rod 12 is fixedly mounted on the top of the output shaft of the linear stepper motor 11. The top of the transmission rod 12 is fixedly connected with a push rod 13 set in the shape of a long rod. The push rod 13 is slidably mounted on the inner wall of the workbench 3. The sliding direction of the push rod 13 is up and down sliding. The number of sliders 9 is set to two groups. The two groups of sliders 9 are slidably mounted on the outer surface of the push rod 13, and the sliding direction of the slider 9 is left and right sliding.

[0033] Reference Figure 4 The rotating mechanism includes a semicircular block 14, which is rotatably mounted on the inner wall of the two groups of clamps 4 on the side close to each other. The semicircular block 14 can rotate slightly on the inner wall of the clamp 4, which can better fit the surface of the interior material with different outer diameters, so that the interior material with different outer diameters can be clamped, and at the same time, the contact area between the surface of the interior material and the clamp 4 is increased, thereby reducing the pressure per unit area of ​​the surface of the interior material and reducing the possibility of deformation and rupture of the interior material. The number of semicircular blocks 14 is set to multiple groups, and multiple rubber balls 15 are fixedly connected to the side close to each other of the multiple groups of semicircular blocks 14. The material of the rubber ball 15 is set to be an elastic rubber material, which can protect the surface of the interior material and prevent the surface of the interior material from being scratched.

[0034] Working principle: When in use, place the locomotive interior material between the two groups of plywood 4, and then start the power supply of the linear stepper motor 11. The linear stepper motor 11 works to drive the transmission rod 12 to move upward, and the displacement of the transmission rod 12 drives the push rod 13 to move upward. The displacement of the push rod 13 pushes the slider 9 to move. Due to the limiting effect of the connecting rod 1 8 and the connecting rod 2 10, the slider 9 can only move in the axial direction of the push rod 13. When the push rod 13 moves upward, the two groups of sliders 9 approach each other, and when the push rod 13 moves downward, the two groups of sliders 9 move away from each other. Therefore, the push rod 13 moves upward and pushes the two groups of sliders 9 to approach each other, thereby squeezing the connecting rod 1 8, so that the connecting rod 1 8 pushes the two groups of plywood 4 above the moving block 5 to approach each other, and the two groups of plywood 4 approach each other until they contact the surface of the interior material and apply a pre-tightening force to the surface of the interior material, thereby improving the clamping stability of the interior material.

[0035] When the locomotive interior material is a material with an arc-shaped surface such as a cylinder, the two sets of splints 4 will approach each other and contact the surface of the interior material through the semicircular blocks 14, and the semicircular blocks 14 can rotate slightly on the inner wall of the splint 4, so that it can better fit the shape of the interior material and have better adaptability. At the same time, the friction with the interior material is increased through the rubber ball 15, reducing the possibility of the interior material slipping during subsequent processing.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
