Description

Technical Field

[0001] The utility model relates to the technical field of coating tooling manufacturing of vehicle lamp parts, in particular to a novel pressing mechanism. Background Art

[0002] In the production process of coating tooling for automotive lamp parts, the complexity of the clamping mechanism affects the difficulty of manufacturing the entire shaft tooling and the coating quality. For example, the patent number CN208628912U is an easy-to-adjust horizontal and vertical clamping mechanism, which drives the movable rod to move upward by moving the pull rod upward, so that the rotation of the driving rod drives the clamping rod to move to the left, thereby cooperating with the clamping plate to achieve the clamping effect; another example is the clamping mechanism and clamping device with patent number CN217345185U, in which the area of ​​the part of the protrusion facing the workpiece is smaller than the area of ​​the part of the main body facing the workpiece, and the protrusion contacts the workpiece to clamp the workpiece, thereby ensuring the processing quality of the workpiece.

[0003] However, the existing clamping mechanisms and clamping mechanisms are generally bulky and heavy, which can easily damage parts. The clamping strength cannot be adjusted, and reducing the strength can easily cause parts to shake. Some connecting rod clamping mechanisms are difficult to operate, and when clamping or clamping parts of different sizes, the pressure head needs to be replaced, which is time-consuming and labor-intensive and not very convenient. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel clamping mechanism, which is quick and labor-saving to operate, and the pressure head can be quickly replaced at any time. The soft silicone pressure head is used for clamping, thereby ensuring that the surface of the part is not easily damaged or deformed.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A novel clamping mechanism comprises a rotating base, a pressure rod with one end connected to the rotating base, a U-shaped plate, a silicone pressure head arranged at the bottom end of the U-shaped plate, a right-angle bracket and a pressure plate rotatably mounted on the right-angle bracket;

[0007] A locking handle is provided at one end of the pressure rod away from the rotating base, and the U-shaped plate is detachably mounted on the middle part of the pressure rod. The pressure rod can be rotated to make the locking handle fall onto the right-angle bracket. Rotating the pressure plate can tighten the locking handle and press the parts through the silicone pressure head at the bottom end of the U-shaped plate in the middle of the pressure rod.

[0008] Furthermore, a positioning slot is provided at the top end of one side of the right-angle bracket, and the pressure rod can be rotated to allow the locking handle to fall into the positioning slot.

[0009] Furthermore, an ear plate is formed at the top end of the other side of the right-angle bracket, and the pressure plate is perpendicular to the right-angle bracket and rotatably mounted on the ear plate.

[0010] Furthermore, a locking screw is passed through the ear plate, a locking nut is assembled at the lower part of the locking screw, a spring is arranged between the locking nut and the ear plate and is sleeved on the locking screw, the pressure plate is tightly attached to the top of the ear plate and is softly pressed by the locking screw, and the pressure plate can rotate around the locking screw.

[0011] Furthermore, a pick is formed on the top of the pressing plate.

[0012] Furthermore, the rotating base includes a hinge seat and a shaft sleeve rotatably mounted on the hinge seat, and one end of the pressure rod is welded to the shaft sleeve.

[0013] Furthermore, the pressure rod is L-shaped.

[0014] Furthermore, the pressure rod and the U-shaped plate are made of stainless steel.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] 1. The utility model is designed with components such as a pressure rod, a right-angle bracket, a pressure plate, and a U-shaped plate. When operating, the pressure rod can be turned up and down to open and close. When tightening, it is only necessary to turn the pressure rod to make the lock handle fall into the right-angle bracket, and then the lock handle can be tightened by turning the pressure plate. At the same time, the parts can be tightened by the silicone pressure head at the bottom of the U-shaped plate. The overall structure is simple and light, the size is small, and the operation is relatively convenient and labor-saving.

[0017] 2. The utility model adopts the design of the silicone pressure head at the bottom end of the U-shaped plate. The soft silicone pressure head is not easy to damage the surface of the parts when pressing the parts, which effectively protects the parts and can appropriately increase the pressing force.

[0018] 3. The U-shaped plate with silicone pressure head of the utility model can be directly put on the pressure rod for use, so it is quick to replace silicone pressure heads of different models. You only need to lift the pressure rod to quickly replace another set of U-shaped plates and silicone pressure heads, which is quick and convenient.

[0019] 4. A positioning slot is provided on the right-angle bracket of the utility model to limit the locking handle, thereby ensuring the accuracy and stability of the pressing and preventing it from shaking.

[0020] 5. The rotational connection between the pressure plate and the ear plate of the utility model is composed of a locking screw, a locking nut and a spring. The spring and the locking screw can form a soft compression on the pressure plate without affecting the rotation of the pressure plate. At the same time, adjusting the height of the locking nut can change the tightness of the spring, and then the clamping force of the locking screw on the pressure plate can be adjusted, thereby changing the clamping force of the pressure plate on the locking handle, and further adjusting the clamping strength of the pressure rod, which is conducive to coordination and adaptation according to the requirements of various parts.

[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, in this embodiment, a new type of clamping mechanism is provided, which is mainly composed of a rotating base, a pressure rod 1, a U-shaped plate 2, a silicone pressure head 3, a right-angle bracket 4, a pressure plate 5 and other components. The pressure rod 1 and the U-shaped plate 2 are made of stainless steel. The rotating base is composed of a hinge seat 90 and a shaft sleeve 91 rotatably mounted on the hinge seat 90. The pressure rod 1 is L-shaped, and one end of the short rod of the pressure rod 1 is welded to the shaft sleeve 91. The end of the pressure rod 1 away from the shaft sleeve 91 is welded with a lock handle 10. The lock handle 10 can be turned to make the pressure rod 1 rotate up and down around the hinge seat 90, thereby realizing the opening and closing action when clamping the parts.

[0027] In order to clamp the parts, a silicone pressure head 3 is provided at the bottom of the U-shaped plate 2, and the U-shaped plate 2 can be detachably sleeved in the middle of the pressure rod 1; at the same time, the pressure plate 5 is rotatably installed on the right-angle bracket 4. During the clamping operation, the locking handle 10 is turned to press the pressure rod 1 downward, and the locking handle 10 can fall into the right-angle bracket 4, and then the pressure plate 5 is horizontally rotated to clamp the locking handle 10, and the silicone pressure head 3 at the bottom of the U-shaped plate 2 in the middle of the pressure rod 1 can clamp the parts. Such operation is relatively quick and labor-saving. And through the design of the silicone pressure head 3 at the bottom of the U-shaped plate 2, it is not easy to damage the surface of the parts when clamping the parts, effectively protect the parts, and appropriately increase the clamping force. In addition, the design of the U-shaped plate 2 with the silicone pressure head 3 can be directly sleeved on the pressure rod 1 for use, so it is relatively quick to replace different types of silicone pressure heads 3. You only need to lift the pressure rod 1 to quickly replace another set of U-shaped plates 2 and silicone pressure heads 3, which is quick and convenient.

[0028] In order to limit the shaking of the lock handle 10, a positioning slot 40 is opened at the top of one side of the right-angle bracket 4 in this embodiment. The rotation of the pressure rod 1 can make the lock handle 10 fall into the positioning slot 40, thereby forming a limit, ensuring the accuracy and stability of the clamping and preventing it from shaking.

[0029] Specifically, an ear plate 41 is formed at the top of the other side of the right angle bracket 4 in this embodiment, and the pressing plate 5 is perpendicular to the right angle bracket 4 and rotatably mounted on the ear plate 41. In order to facilitate the adjustment of the pressing strength, a locking screw 6 is inserted through the ear plate 41, and a locking nut 7 is assembled at the lower part of the locking screw 6. A spring 8 sleeved on the locking screw 6 is arranged between the locking nut 7 and the ear plate 41. The pressing plate 5 is tightly attached to the top of the ear plate 41 and is softly pressed by the locking screw 6, that is, the pressing plate 5 can rotate around the locking screw 6. Therefore, the rotational connection between the pressure plate 5 and the ear plate 41 is composed of a locking screw 6, a locking nut 7 and a spring 8. The spring 8 and the locking screw 6 can form a soft pressure on the pressure plate 5 without affecting the rotation of the pressure plate 5. At the same time, adjusting the height of the locking nut 7 can change the tightness of the spring 8, and then the pressing force of the locking screw 6 on the pressure plate 5 can be adjusted, thereby changing the pressing force of the pressure plate 5 on the locking handle 10, and further adjusting the pressing strength of the pressure rod 5, which is conducive to coordination and adaptation according to various parts requirements.

[0030] In order to facilitate the movement of the pressing plate 5 , a paddle 50 is formed on the top of the pressing plate 5 in the present embodiment, and the movement is more labor-saving and convenient through the paddle 50 .

[0031] Through the above-mentioned design, the present embodiment can realize opening and closing by rotating the pressure rod 1 up and down during operation. When tightening, it is only necessary to rotate the pressure rod 1 to make the locking handle 10 fall into the right-angle bracket 4, and then the locking handle 10 can be tightened by rotating the pressure plate 5. At the same time, the parts can be tightened by relying on the silicone pressure head 3 at the bottom end of the U-shaped plate 2. The overall structure of the present embodiment is simple and lightweight, the size is small, and the operation is relatively convenient and labor-saving.
