Description

Technical Field

[0001] This utility model relates to the field of nut equipment technology, specifically a clamping device for nut processing. Background Technology

[0002] In the process of nut processing, a clamping device is required. Patent publication number CN207642442U discloses a clamping device for nut processing, including a base. The top of the base is fixedly connected to the bottom of a support platform. A processing device is fixedly installed on the top of the support platform. A clamping device is fixedly installed on the top of the base at a position adapted to the processing device. By setting a turbine, the left and right movement of the concave clamping block is more convenient and labor-saving, improving the efficiency of the clamping work. By setting a screw, the concave clamping block can more accurately clamp and fix the edges of the nut to be processed, making it less likely for the nut to move and providing a better clamping effect. By setting a push block, operation is convenient and clamping is stable. By setting a limiting threaded rod, the clamping is more stable and the nut is less likely to slip. By clamping the nut to be processed in three different directions, the clamping effect is better, improving the operator's work.

[0003] The existing technical solution described above has the following drawbacks: the push block and the concave clamping block fix the nut together. The concave clamping block has a groove for matching the nut, while the push block is a flat surface. The contact method between the push block and the nut is a point contact method. Therefore, the clamping and fixing effect between the push block and the nut is limited. When the nut is pushed by a strong external force, the side of the nut that is fixed to the push block is easy to loosen, which reduces the effectiveness of the clamping device. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a clamping device for nut processing, which has the advantage of efficient clamping. It solves the problem that when a push block and a concave clamping block fix the nut, the concave clamping block has a groove to fit the nut, while the push block is a flat surface. The contact between the push block and the nut is a point contact, so the clamping and fixing effect between the push block and the nut is limited. When the nut is pushed by a strong external force, the side of the nut fixed to the push block is prone to loosening, which reduces the effectiveness of the clamping device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for nut processing, comprising a housing, a nut body being provided on the top of the housing, clamping plates being provided on both sides of the nut body, a movable plate being fixedly installed on the outer side of the clamping plates, the bottom of the movable plate extending into the interior of the housing, a transverse sliding plate being fixedly connected to the bottom of the movable plate, and a control mechanism being fixedly connected inside the housing.

[0006] In a preferred embodiment of this utility model, the control mechanism includes a motor, which is fixedly connected to the top of the inner wall of the housing. A screw is fixedly connected to the output end of the motor, and a lifting plate is threadedly connected to the bottom of the screw surface. Both sides of the top of the lifting plate are movably connected to transmission plates, and the top of the transmission plates is movably connected to the bottom of the transverse plate.

[0007] As a preferred embodiment of this invention, a positioning groove is provided at the bottom of the inner wall of the box, and the inner wall of the positioning groove is in contact with the surface of the screw.

[0008] As a preferred embodiment of this invention, the screw has a threaded sleeve connected to its surface, and the bottom of the threaded sleeve is fixedly connected to the top of the lifting plate.

[0009] As a preferred embodiment of this utility model, each of the four corners of the lifting plate is slidably connected with a vertical rod, and the surface of the vertical rod is fixedly connected to the inner wall of the box.

[0010] As a preferred embodiment of this invention, the transverse sliding plate is provided with a sliding rod inside, and the surface of the sliding rod is fixedly connected to the inner wall of the box.

[0011] As a preferred embodiment of this utility model, ventilation grooves are provided on the top of both the front and rear sides of the housing, and the ventilation grooves are located on the front and rear sides of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a screw to rotate, which in turn drives a lifting plate to move upward. The lifting plate then drives a transmission plate to move upward, while the transmission plate rotates simultaneously. During this rotation, the transmission plate pushes a transverse plate and a moving plate to move away from the nut body. The moving plate then drives a clamping plate to move away from the nut body. After the clamping plate separates from the nut body, the nut body is released. Because the clamping plates on both sides have the same wrapping effect, the nut body can be stably clamped, achieving the advantage of efficient clamping. The clamping components on both sides of the nut have a good wrapping effect, resulting in a good clamping and fixing effect on the nut, thus improving the effectiveness of the clamping device.

[0014] 2. By setting up a control mechanism, this utility model can control the clamping plate, avoiding the inability of the clamping plate to move during use, which would prevent the clamping plate from being unable to fix the nut body, thus improving the clamping and fixing efficiency of the nut body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a clamping device for nut processing, including a housing 1, a nut body 2 on the top of the housing 1, clamping plates 3 on both sides of the nut body 2, a movable plate 4 fixedly installed on the outer side of the clamping plates 3, the bottom of the movable plate 4 extending into the interior of the housing 1, a transverse sliding plate 5 fixedly connected to the bottom of the movable plate 4, and a control mechanism 6 fixedly connected inside the housing 1.

[0022] refer to Figure 2 The control mechanism 6 includes a motor 61, which is fixedly connected to the top of the inner wall of the housing 1. A screw 62 is fixedly connected to the output end of the motor 61. A lifting plate 63 is threadedly connected to the bottom of the surface of the screw 62. A transmission plate 64 is movably connected to both sides of the top of the lifting plate 63. The top of the transmission plate 64 is movably connected to the bottom of the transverse plate 5.

[0023] As a technical optimization of this utility model, by setting the control mechanism 6, the clamping plate 3 can be controlled, avoiding the clamping plate 3 being unable to move during use, which would prevent the clamping plate 3 from being unable to fix the nut body 2, thus improving the clamping and fixing efficiency of the nut body 2.

[0024] refer to Figure 3 A positioning groove 7 is provided at the bottom of the inner wall of the housing 1, and the inner wall of the positioning groove 7 is in contact with the surface of the screw 62.

[0025] As a technical optimization of this utility model, by setting the positioning groove 7, the screw 62 can be stabilized, avoiding the phenomenon of skewness during the rotation of the screw 62, and improving the stability of the screw 62 in use.

[0026] refer to Figure 3 The screw 62 has a threaded connection to a screw sleeve 8, and the bottom of the screw sleeve 8 is fixedly connected to the top of the lifting plate 63.

[0027] As a technical optimization of this utility model, by setting the screw sleeve 8, the threaded connection area between the screw 62 and the lifting plate 63 can be increased, avoiding the small threaded connection area between the screw 62 and the lifting plate 63, which would lead to unstable cooperation between the screw 62 and the lifting plate 63, and improving the stability of the use of the screw 62 and the lifting plate 63.

[0028] refer to Figure 2 Vertical rods 9 are slidably connected to the four corners of the lifting plate 63, and the surfaces of the vertical rods 9 are fixedly connected to the inner wall of the box 1.

[0029] As a technical optimization of this utility model, by setting the vertical rod 9, the lifting plate 63 can be stabilized during sliding, avoiding shaking of the lifting plate 63 during sliding and moving, which would cause the lifting plate 63 to loosen, thus improving the sliding stability of the lifting plate 63.

[0030] refer to Figure 2 The transverse plate 5 is equipped with a slide rod 10 inside, and the surface of the slide rod 10 is fixedly connected to the inner wall of the box 1.

[0031] As a technical optimization of this utility model, by setting the slide bar 10, the sliding plate 5 can be stabilized during sliding, avoiding the swaying of the sliding plate 5 during sliding and moving, which would cause the sliding plate 5 to loosen, thus improving the sliding stability of the sliding plate 5.

[0032] refer to Figure 1 Ventilation slots 11 are provided on the top of the front and rear sides of the housing 1, and the ventilation slots 11 are located on the front and rear sides of the motor 61.

[0033] As a technical optimization of this utility model, by setting the ventilation groove 11, the heat inside the box 1 can be dissipated, avoiding the airflow inside the box 1 from not being able to dissipate, which would cause the motor 61 to overheat and improve the working safety of the motor 61.

[0034] The working principle and usage process of this utility model are as follows: In use, the nut body 2 is fixed in the figure. When it is necessary to loosen the nut body 2, the motor 61 is started. The motor 61 drives the screw 62 to rotate. The screw 62 drives the lifting plate 63 to move upward. The lifting plate 63 drives the transmission plate 64 to move upward. At the same time, the transmission plate 64 rotates. During the rotation of the transmission plate 64, it pushes the transverse plate 5 and the moving plate 4 to move away from the nut body 2. The moving plate 4 drives the clamping plate 3 to move away from the nut body 2. After the clamping plate 3 separates from the nut body 2, the nut body 2 is loosened. Since the clamping plates 3 on both sides have the same wrapping properties, the nut body 2 can be stably clamped.

[0035] In summary, this clamping device for nut processing, through the coordinated use of housing 1, nut body 2, clamping plate 3, moving plate 4, transverse plate 5, and operating mechanism 6, solves the problem of fixing the nut by a push block and a concave clamping block. The concave clamping block has a groove for fitting the nut, while the push block is a flat surface. The contact between the push block and the nut is a point contact, so the clamping and fixing effect between the push block and the nut is limited. When the nut is pushed by a strong external force, the side of the nut fixed to the push block is prone to loosening, reducing the effectiveness of the clamping device.
