Description

Technical Field

[0001] This utility model relates to the field of clamping fixtures, specifically a clamping fixture for coating equipment. Background Technology

[0002] A fixture is a process device used during machining to quickly secure a workpiece and maintain the correct relative position of the machine tool, cutting tool, and workpiece. In other words, tooling fixtures are an indispensable component of machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent, and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, versatility, and economy.

[0003] Chinese Patent No. CN202121208218.8 discloses a general-purpose optical coating fixture, including a clamping base. Motor housings are fixedly installed on the left and right sides of the clamping base, and servo motors are fixedly installed inside the motor housings. A bearing is sleeved at the end of the servo motor, and a rotating column is sleeved inside the other end of the bearing. A work box is welded to the other end of the rotating column, and an electric push rod is fixedly installed inside the work box. A connecting block is provided on the opposite surface of the electric push rod, and a groove is provided inside the connecting block. A protrusion is movably connected inside the groove, and a connecting groove is opened inside the protrusion. A limiting rod is movably sleeved inside the connecting groove, and a push block is welded to the front of the limiting rod. A spring is provided on the outside of the limiting rod. A connecting plate is welded to the opposite surface of the protrusion, and a soft rubber clamping block is provided at the other end of the connecting plate.

[0004] As can be seen from the above, controlling the servo motor makes it easy to rotate the soft rubber clamping block, which facilitates coating the other side of the coating element without stopping the machine to complete the coating work on the other side of the coating element, shortening the coating time and improving the coating efficiency. However, this solution also has the following shortcomings: when clamping the processing materials, due to the different sizes of the materials, the single fixing method is not versatile enough. It can often only fix materials of the same size. When different sizes of materials need to be fixed, the clamping components need to be replaced or other sizes of clamping equipment need to be purchased, which makes the operation more cumbersome and cannot be adapted to the actual situation.

[0005] Therefore, a clamping fixture for coating equipment is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, which often only allow for fixing materials of the same size and specifications, this utility model proposes a clamping fixture for coating equipment.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The clamping fixture for coating equipment of this utility model includes a base and a clamping adjustment assembly; the clamping adjustment assembly is equipped with a fixed plate, a first servo motor is fixedly installed on one side of the fixed plate, a ball screw is fixedly installed at the output end of the first servo motor, the ball screw is movably installed with the fixed plate, a ball nut is threaded through and connected to the ball screw, a fixed frame is fixedly installed on the top of the ball nut, several sliders are fixedly installed on the bottom of the fixed frame, two limiting rods are movably installed on the bottom of each of the sliders, and the bottoms of the two limiting rods are fixedly installed with the fixed plate.

[0008] Preferably, the base is equipped with a support leg, a work platform is fixedly installed on the top of the support leg, a fixing plate is fixedly installed on the top of the work platform, and another fixing frame is fixedly installed on the top of the fixing plate.

[0009] Preferably, a mounting bracket is fixedly installed on the top of each of the two mounting brackets, a second servo motor is fixedly installed on one side of each of the two mounting brackets, a first transmission wheel is fixedly installed at the output end of the second servo motor, a transmission belt is driven around the first transmission wheel, and a second transmission wheel is driven on the other side of the transmission belt.

[0010] Preferably, a trapezoidal lead screw is installed through and fixedly mounted on the second transmission wheel, a mounting bracket is installed through and movably mounted on one side of the trapezoidal lead screw, a fixed seat is fixedly mounted on one side of the mounting bracket, and the trapezoidal lead screw is installed through and movably mounted on one side of the fixed seat.

[0011] Preferably, the fixed base is hinged with several clamping arms around its perimeter, and each of the clamping arms is hinged with a linkage arm on one side. The other end of each linkage arm is hinged with a trapezoidal nut, and the trapezoidal nut is threaded through and connected to a trapezoidal lead screw.

[0012] Preferably, the trapezoidal nut is fixedly mounted with a spring, and a fixing seat is fixedly mounted on the other side of the spring.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, through the structural design of the clamping and adjusting component, drives the first servo motor to rotate the ball screw at the output end, so that the ball screw cooperates with the ball nut. Thus, the rotation of the first servo motor drives the trapezoidal screw to perform corresponding horizontal linear movement. The top of the ball nut is fixed with a fixing frame. As the first servo motor rotates, it is easier to control the distance of movement of the fixing frame, realizing the function of movable adjustment. This solves the problem that it can only fix materials of the same size and specifications, and improves the adaptability in use.

[0015] 2. Through the structural design of the clamping adjustment component, the movement of the trapezoidal nut is linked to the clamping arm by the linkage arm, so that the clamping arm moves in a circle around the hinge of the fixed seat. At this time, several clamping arms tighten inward to clamp the processing material, thus realizing the function of movable clamping. Attached Figure Description

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1-5As shown, a clamping fixture for a coating equipment includes a base 1 and a clamping adjustment assembly 2. The clamping adjustment assembly 2 is equipped with a fixed plate 21. A first servo motor 22 is fixedly installed on one side of the fixed plate 21. A ball screw 23 is fixedly installed at the output end of the first servo motor 22. The ball screw 23 is movably installed with the fixed plate 21. A ball nut 24 is threaded through and connected to the fixed plate 21. A fixed frame 26 is fixedly installed on the top of the ball nut 24. Several sliders 25 are fixedly installed on the bottom of the fixed frame 26. Two limiting rods 27 are movably installed on the bottom of each slider 25. The bottoms of the two limiting rods 27 are fixedly installed with the fixed plate 21.

[0025] During operation, the first servo motor 22 provides power to drive the ball screw 23 to rotate. With the threaded engagement between the ball screw 23 and the ball nut 24, the rotational motion is converted into linear motion, which drives the fixed frame 26 to move relative to each other. To prevent the fixed frame 26 from shaking during the displacement, the slider 25 and the limit rod 27 are used to limit its movement, so that the fixed frame 26 always moves horizontally.

[0026] Furthermore, the base 1 is equipped with a support leg 11, a work platform 12 is fixedly installed on the top of the support leg 11, a fixing plate 21 is fixedly installed on the top of the work platform 12, and another fixing bracket 26 is fixedly installed on the top of the fixing plate 21.

[0027] During operation, the installation of support legs 11 helps to provide appropriate support for the whole, ensuring the stability of the top components of the work platform 12 during operation.

[0028] Furthermore, mounting brackets 28 are fixedly installed on the top of the two fixed brackets 26 respectively, and second servo motors 29 are fixedly installed on one side of the two mounting brackets 28 respectively. A first transmission wheel 31 is fixedly installed at the output end of the second servo motor 29. A transmission belt 32 is connected around the first transmission wheel 31, and a second transmission wheel 33 is connected to the other side of the transmission belt 32.

[0029] During operation, the mounting bracket 28 facilitates the support of the top components and provides corresponding limits to ensure the stability of the transmission process.

[0030] Furthermore, a trapezoidal lead screw 34 is fixedly installed through the second transmission wheel 33, a mounting bracket 28 is movably installed through one side of the trapezoidal lead screw 34, a fixed seat 35 is fixedly installed on one side of the mounting bracket 28, and the trapezoidal lead screw 34 is movably installed through one side of the fixed seat 35.

[0031] During operation, the movable installation of the trapezoidal lead screw 34 via the mounting bracket 28 and the fixed base 35 facilitates the limiting of the trapezoidal lead screw 34, ensuring that it always maintains the same position for rotational movement.

[0032] Furthermore, several clamping arms 36 are hinged around the fixed base 35, and a linkage arm 37 is hinged to one side of each clamping arm 36. A trapezoidal nut 38 is hinged to the other end of the linkage arm 37, and a trapezoidal screw 34 is threaded through and connected to the trapezoidal nut 38.

[0033] During operation, the trapezoidal lead screw 34 works in conjunction with the trapezoidal nut 38 to drive the trapezoidal nut 38 to make relative displacement. During movement, the linkage arm 37 generates linkage with the clamping arm 36, causing the clamping arm 36 to rotate around the hinge of the fixed seat 35.

[0034] Furthermore, a spring 39 is fixedly installed on the trapezoidal nut 38, and a fixing seat 35 is fixedly installed on the other side of the spring 39;

[0035] During operation, the spring 39 deforms under external force due to its unique elasticity and returns to its original shape after the external force is removed. The spring 39 generates stress on one side of the trapezoidal nut 38, which helps to ensure the stability of the trapezoidal nut 38 when it is threaded with the trapezoidal lead screw 34.

[0036] Working principle: In embodiment one, the first transmission wheel 31 at the output end is rotated by driving the second servo motor 29. The first transmission wheel 31 drives the second transmission wheel 33 through the transmission belt 32, thereby causing the second transmission wheel 33 to drive the trapezoidal lead screw 34 to rotate relative to it. When the trapezoidal lead screw 34 rotates, it cooperates with the trapezoidal nut 38 to convert the rotational motion into the linear motion of the trapezoidal nut 38. As the trapezoidal nut 38 moves, the linkage arm 37 links the clamping arm 36, causing the clamping arm 36 to move in a circle around the hinge of the fixed seat 35. At this time, several clamping arms 36 tighten inward to clamp the processed material.

[0037] In the second embodiment, when the specifications of the material to be processed need to be adapted, the first servo motor 22 is driven to rotate the ball screw 23 at the output end, so that the ball screw 23 cooperates with the ball nut 24. Thus, the rotation of the first servo motor 22 drives the trapezoidal screw 34 to perform corresponding horizontal linear movements. The top of the ball nut 24 is fixed with a fixing bracket 26. As the first servo motor 22 rotates, it is beneficial to control the distance of movement of the fixing bracket 26, so that the whole system can adapt to the length of the material to be processed.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
