Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a detachable coating hanger positioning pin structure. Background Technology

[0002] Coating hangers are specialized tooling equipment used in coating production lines to suspend and fix workpieces to be coated. They can ensure that the workpieces maintain the correct position and posture during the coating process, prevent the workpieces from shaking, shifting or falling, and ensure the uniformity and accuracy of the coating.

[0003] In existing painting fixture positioning pin structures, paint layers inevitably adhere to the surface of the positioning pins during actual painting operations. As the usage time increases, the paint layer accumulates and thickens, causing changes in the shape and size of the positioning pins. This prevents the product from being properly hung on the positioning pins, affecting the suspension and positioning of the workpiece. Furthermore, it is difficult to clean the paint layer from the fixed positioning pins. Therefore, a detachable painting fixture positioning pin structure is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable painting hanger positioning pin structure, which solves the problem that paint layers inevitably adhere to the surface of the positioning pin. As the usage time increases, the paint layer continues to accumulate and thicken, causing changes in the shape and size of the positioning pin. This prevents the product from being properly hung on the positioning pin, affecting the suspension and positioning of the workpiece. Furthermore, it makes it difficult to clean the surface paint layer of the fixed positioning pin.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a mounting frame, and a positioning pin mechanism and a reinforcing mechanism are provided below the mounting frame;

[0008] The positioning pin mechanism includes a positioning pin;

[0009] A fixing frame is fixedly installed on the bottom surface of the mounting bracket. The outer wall of the fixing frame is slidably connected to the inner side of the positioning pin. A slot is opened on the inner side of the positioning pin. An insert block is slidably installed through the inner side of the fixing frame and extends to the inner wall of the slot.

[0010] Preferably, the reinforcement mechanism includes an elastic reinforcement frame, the top surface of which is fixedly connected to the bottom surface of the fixed frame. A fixed rod is fixedly installed on the inner side of the elastic reinforcement frame, and a lifting sleeve is slidably sleeved on the outer wall of the fixed rod. Two reinforcement plates are hinged to the outer wall of the lifting sleeve, and the outer walls of both reinforcement plates are hinged to the inner side of the elastic reinforcement frame. The reinforcement mechanism can reinforce the frame after the positioning pin is installed, and the reinforcement plates can be unfolded and hinged to the elastic reinforcement frame to form multi-angle, all-round support and reinforcement, further improving stability.

[0011] Preferably, two compression springs and two compression dampers are fixedly installed on the inner side of the fixed frame. Compression plates are fixedly installed on the outer walls of the two compression springs and the two compression dampers. Under the action of the compression springs and the compression dampers, the compression plates will move towards one side of the fixed frame.

[0012] Preferably, the side of the extrusion plate near the insert block is fixedly connected to the outer wall of the insert block, and both extrusion springs are initially in an extended state. Since the two extrusion springs are initially in an extended state, they will exert an outward pushing force on the extrusion plate, thereby pushing the insert block to be firmly inserted into the slot, forming a reliable mechanical connection.

[0013] Preferably, the outer wall of the lifting sleeve is threaded with a pressing screw extending to the inner side of the lifting sleeve.

[0014] Preferably, the outer wall of the fixing rod is provided with an extrusion groove, and one end of the extrusion screw located inside the lifting sleeve extends to the inner wall of the extrusion groove. By rotating the extrusion screw, under the action of the thread on the outer wall of the lifting sleeve, the end of the extrusion screw located inside the lifting sleeve will extrude the extrusion groove, thereby fixing the lifting sleeve.

[0015] (III) Beneficial Effects

[0016] This utility model provides a detachable painting hanger positioning pin structure. It has the following beneficial effects:

[0017] (i) The detachable coating hanger positioning pin structure achieves precise guidance and initial positioning through the sliding cooperation between the fixed frame and the inner side of the positioning pin. With the help of the compression spring and compression damper, the insert block is driven to slide into the slot quickly and accurately to form a reliable mechanical connection. This not only realizes the quick installation and removal of the positioning pin, overcoming the problem of the complex installation and removal of traditional positioning pins, and ensuring the efficient operation of the coating production line, but also uses the thrust generated by the initial extension state of the compression spring to push the insert block firmly into the slot, ensuring that the positioning pin is stably fixed under the mounting frame, and meeting the stability requirements of the coating hanger for the positioning pin.

[0018] (ii) This detachable coating fixture positioning pin structure has a reinforcement mechanism that is fixedly connected to the fixed frame through an elastic reinforcement frame. The rotating extrusion screw drives the lifting sleeve to slide on the fixed rod, causing the hinged reinforcement plate to unfold and make close contact with the surrounding components, forming multi-angle and all-round support reinforcement. This not only effectively resists vibration and external impact during the coating process and prevents the positioning pin from shaking or shifting, ensuring accurate workpiece positioning and coating quality, but also allows for flexible changes in the unfolding angle and support strength of the reinforcement plate by adjusting the extrusion screw. This adapts to the diverse needs of different coating processes and workpieces for positioning pin installation and fixation, improving the versatility and flexibility of the coating fixture positioning pin.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-5 The present invention provides a technical solution: including a mounting frame 1, and a positioning pin mechanism 2 and a reinforcing mechanism 3 are provided below the mounting frame 1;

[0027] Positioning pin mechanism 2 includes positioning pin 21;

[0028] A fixed frame 22 is fixedly installed on the bottom surface of the mounting bracket 1. The outer wall of the fixed frame 22 is slidably connected to the inner side of the positioning pin 21. A slot 24 is opened on the inner side of the positioning pin 21. An insert 23 is slidably inserted through the inner side of the fixed frame 22 and extends to the inner wall of the slot. Two compression springs 25 and two compression dampers 26 are fixedly installed on the inner side of the fixed frame 22. A compression plate 27 is fixedly installed on the outer wall of the two compression springs 25 and the two compression dampers 26. The side of the compression plate 27 near the insert 23 is fixedly connected to the outer wall of the insert 23. The two compression springs 25 are initially in the extended state.

[0029] The reinforcement mechanism 3 includes an elastic reinforcement frame 31. The top surface of the elastic reinforcement frame 31 is fixedly connected to the bottom surface of the fixed frame 22. A fixed rod 32 is fixedly installed on the inner side of the elastic reinforcement frame 31. A lifting sleeve 34 is slidably sleeved on the outer wall of the fixed rod 32. Two reinforcement plates 33 are hinged on the outer wall of the lifting sleeve 34. The outer walls of the two reinforcement plates 33 are both hinged to the inner side of the elastic reinforcement frame 31. A pressing screw 35 is threaded through the outer wall of the lifting sleeve 34 and extends to the inner side of the lifting sleeve 34. A pressing groove 36 is opened on the outer wall of the fixed rod 32. One end of the pressing screw 35 located on the inner side of the lifting sleeve 34 extends to the inner wall of the pressing groove 36.

[0030] In use, the fixed frame 22 is fixed to the bottom surface of the mounting bracket 1, and its outer wall slides in cooperation with the inner side of the positioning pin 21, providing guidance and initial positioning for the installation of the positioning pin 21. When the positioning pin 21 moves upward along the fixed frame 22, the insert 23 can slide precisely into the slot 24 on the inner side of the positioning pin 21 under the action of the compression spring 25 and the compression damper 26. Since the two compression springs 25 are initially in the extended state, they will generate an outward pushing force on the compression plate 27, thereby pushing the insert 23 to be firmly inserted into the slot 24, forming a reliable mechanical connection, and fixing the positioning pin 21 stably under the mounting bracket 1, so as to realize the installation and fixing of the positioning pin 21 to meet the positioning requirements of the painting hanger.

[0031] The elastic reinforcing frame 31 is fixedly connected to the fixed frame 22. As the lifting sleeve 34 slides, the two reinforcing plates 33 hinged to it will rotate around the hinge point, gradually unfold and come into close contact with the surrounding parts, forming multi-angle support and reinforcement for the positioning pin 21, effectively preventing the positioning pin 21 from shaking or displacing due to external force during the painting process. When it is necessary to enhance the stability of the positioning pin 21, the extrusion screw 35 is rotated. Under the action of the thread on the outer wall of the lifting sleeve 34, the end of the extrusion screw 35 located on the inner side of the lifting sleeve 34 will extrude the extrusion groove 36, thereby fixing the lifting sleeve 34.

[0032] When disassembling the positioning pin 21, the squeezing screw 35 is operated in the opposite direction, allowing the lifting sleeve 34 to slide above the fixed rod 32, thus releasing the reinforcing effect of the reinforcing mechanism 3. At the same time, the elastic force of the squeezing spring 25 is overcome, and the insert 23 is pulled out of the slot 24. At this time, the positioning pin 21 loses the limiting effect of the insert 23 and can slide downward along the fixed frame 22, realizing the separation of the positioning pin 21 from the mounting bracket 1. Furthermore, since the elastic reinforcing bracket 31 can retract inward during the downward movement of the positioning pin 21, the disassembly of the positioning pin 21 can be completed.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
