Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology, and in particular to a surface treatment tool with an adjustable counterweight structure. Background Technology

[0002] Surface treatment fixtures are special tools used in industrial production for fixed support or auxiliary processing. Their structural design needs to be customized according to the shape of the workpiece and process requirements. The main body material is often aluminum alloy, stainless steel or engineering plastic to ensure durability. During the surface treatment process, the fixtures can be used in conjunction with processes such as sandblasting, electroplating and spraying to achieve uniform coverage. The modular design facilitates quick replacement of parts to adapt to diverse production tasks. The precision positioning function helps to improve the consistency of coating thickness. Some fixtures integrate cooling systems to prevent deformation caused by high temperature. The reasonable use of such tools can effectively improve the yield rate and reduce the rework rate, while reducing material waste and labor costs.

[0003] A search revealed Chinese patent publication number CN221854725U, which discloses a hot-dip galvanizing hanger, comprising an L-shaped plate with a groove inside. Several sliders are slidably connected within the groove, each slider having a threaded groove with varying thread density. The sliders are threadedly connected to the same first lead screw, the outer wall of which is provided with a worm gear meshing with a worm. One end of the worm is connected to the corresponding end of a fixed rod. This hot-dip galvanizing fixture, by incorporating a sliding groove, slider, threaded groove, first lead screw, worm gear, and worm, allows for the adjustment of the spacing between the hook plates during the hot-dip galvanizing process. This enables the fixture to be used for hot-dip galvanizing of parts of different sizes, thus preventing interference caused by insufficient spacing between parts during the process and ensuring the fixture's applicability. However, in practical use, the aforementioned device lacks an installation and fixing mechanism, making it impossible to effectively fix and adjust the counterweight. Therefore, a surface treatment tooling with an adjustable counterweight structure is proposed to solve the above problems. Utility Model Content

[0019] The above technical solution involves deploying a limiting mechanism on the side of the skateboard. This mechanism includes a sliding column that slides in conjunction with the inner wall of the skateboard. A groove is opened on the surface of the skateboard, and the sliding column moves along the groove trajectory to directly control the lifting stroke of the lower pressure seat. A limiting block is set on the surface of the sliding column to prevent the displacement of the sliding column from exceeding the design range. The lower pressure seat is fixed at the end of the sliding column, forming a complete pressure transmission link.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the support platform has two counterweight grooves, and multiple alloy columns are fixedly connected to the bottom of the outer wall of the support platform.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, when it is necessary to add a counterweight to the counterweight groove, it is only necessary to rotate the screw to make the sliding column slide longitudinally, thereby making the lower pressure seat move upward.

[0041] The locking mechanism 2 includes a rod 202, the outer wall of which is slidably connected to the inner wall of the support platform 1. The outer wall of the support platform 1 is provided with a first groove 201. A first spring 203 is fixedly connected to the outer wall of the rod 202. The first spring 203 on the rod 202 is used to fasten the counterweight component through the sliding track. An annular groove 205 is provided on the outer wall of the rod 202. The annular groove 205 is used to place the limiting ring 204. When the counterweight component needs to be added, the locking mechanism 2 is temporarily in the unlocked state by twisting the limiting ring 204. The limiting ring 204 is rotatably connected to the outer wall of the annular groove 205. A pull button 206 is fixedly connected to the front end of the outer wall of the rod 202, which is used to pull the rod 202.

[0042] Specifically, the support platform 1 and the slide plate 8 work together. The slide plate 8 acts as an intermediate medium to ensure the stability of the control process. The support platform 1, as the core load-bearing frame, is responsible for integrating the installation and positioning of the tooling components and maintaining the overall structural strength and rigidity of the system. A locking mechanism 2 is configured on the outside of the support platform 1, and an adaptive mechanism 3 extends from its bottom. A reinforcement mechanism 4 is integrated on the surface of the slide plate 8. This mechanism is composed of a screw 402, which forms an adjustable connection with the inner wall of the slide plate 8 through threads. A knob 401 is fixed on the top of the screw 402. The two work together to drive the lower pressure seat 604 to apply vertical pressure to the counterweight component along the threaded trajectory. A sliding crossbar 7 is provided on the side of the support platform 1. A clamping mechanism 5 is mounted on the surface of the horizontal bar 7. This mechanism includes a side plate 501, which is rigidly connected to the horizontal bar 7. A friction strip 502 is attached to the surface of the side plate 501. The three components work together to form a lateral constraint force, improving the horizontal stability of the counterweight component. A limiting mechanism 6 is deployed on the side of the slide plate 8. This mechanism includes a sliding column 603, which slides in contact with the inner wall of the slide plate 8. A groove 601 is opened on the surface of the slide plate 8. The sliding column 603 moves along the trajectory of the groove 601, directly controlling the lifting stroke of the lower pressure seat 604. A limiting block 602 is set on the surface of the sliding column 603 to prevent the displacement of the sliding column 603 from exceeding the design range. The end of the sliding column 603 is fixed to the lower pressure seat. The seat 604 forms a complete pressure transmission link. The locking mechanism 2 is composed of a rod 202, which forms a sliding pair with the inner wall of the support platform 1. A first groove 201 is opened on the surface of the support platform 1 as a guide path. A first spring 203 is fixed on the surface of the rod 202. The counterweight component is quickly locked by the spring tension and the cooperation of the sliding track. An annular groove 205 is opened in the middle of the rod 202. A limit ring 204 is embedded in the groove. When a counterweight component needs to be added, rotating the limit ring 204 can temporarily release the locking state. The outer side of the annular groove 205 is rotatably connected to the limit ring 204. A pull button 206 is fixed at the front end of the rod 202. The locking mechanism is activated by pulling. The axial movement of the rod 202 is achieved by the adaptive mechanism 3 located at the bottom of the support platform 1, which dynamically fits the contact surface through elastic elements to compensate for minor deviations during assembly. The knob 401 of the reinforcement mechanism 4 adopts an anti-slip texture design to enhance the efficiency of torque transmission. The friction strip 502 of the clamping mechanism 5 is made of a high friction coefficient material, which offsets the inertial offset of the counterweight component through lateral clamping force. The slide groove 601 of the limiting mechanism 6 adopts a gradient width design, with the first half being a free sliding area and the second half being a deceleration buffer zone. It works in conjunction with the limiting block 602 to achieve precise stroke control. The bottom surface of the lower pressure seat 604 is equipped with a pressure distribution structure to ensure that the counterweight component is evenly stressed.

[0043] Reference Figure 1 and Figure 4The adaptive mechanism 3 includes a pull bar 301 for supporting the object to be measured at the bottom. The top of the outer wall of the pull bar 301 is fixedly connected to the bottom of the outer wall of the support platform 1. A curved column 302 is fixedly connected to the bottom of the outer wall of the pull bar 301 for autonomous angle adjustment. A support plate 303 is fixedly connected to the outer wall of the curved column 302. A second slot 304 is provided on the outer wall of the support plate 303 to facilitate the sliding of the pin strip 305. The pin strip 305 is slidably connected to the inner wall of the second slot 304. A limit plate 306 is fixedly connected to the top of the outer wall of the pin strip 305 to fix the object to be measured and prevent it from falling off.

[0044] Specifically, the adaptive mechanism 3 consists of a pull bar 301, which supports the object to be tested at the bottom. Its top end is rigidly connected to the bottom of the outer wall of the support platform 1. A curved column 302 is fixed at the bottom, used to dynamically adjust the contact angle. A support plate 303 is connected to the end of the curved column 302. A second groove 304 is formed on the surface of the support plate 303, providing a sliding path for the pin-type strip 305. The inner wall of the second groove 304 forms a sliding pair with the pin-type strip 305. A limiting plate 306 is fixed to the top of the pin-type strip 305, constraining the contact surface between the limiting plate 306 and the object to be tested, preventing it from slipping during the test. If displacement or detachment occurs, the adaptive mechanism 3 compensates for the change in the posture of the object under test in real time through the elastic deformation of the tie bar 301 and the angle adaptive characteristics of the curved column 302. The second slot 304 of the support plate 303 adopts a linear guide design to ensure that the pin bar 305 moves along the preset trajectory. The limiting plate 306 and the pin bar 305 adopt an integrated molding process to enhance the structural strength. Wear-resistant bushings are set at the hinge of the curved column 302 and the support plate 303 to reduce the frictional resistance during angle adjustment. The tie bar 301 adopts a gradient cross section design to give it flexible support capability in the vertical direction and maintain rigid constraint in the horizontal direction.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the support platform 1 has two counterweight grooves 9, which provide a dedicated space for installing counterweight blocks 11, facilitating quick positioning and adjustment of counterweights during balance adjustment. Multiple alloy columns 10 are fixedly connected to the bottom of the outer wall of the support platform 1. The alloy columns 10 are used to support the support platform 1. The outer wall of the counterweight grooves 9 is fixedly connected to the counterweight blocks 11, which offset the unbalanced torque of the workpiece or tooling by increasing or decreasing the weight, ensuring the stability and safety of the operation process. The counterweight grooves 9 are symmetrically distributed along the central axis of the support platform 1. The bottom of the outer wall of the support platform 1 is fixedly connected to the part to be plated 12, which is a component waiting for heat treatment. The bottom of the outer wall of the limiting plate 306 is fixedly connected to the top of the outer wall of the part to be plated 12.

[0046] Specifically, two counterweight grooves 9 are provided on the outer wall of the support platform 1 to provide installation space for the counterweight blocks 11, facilitating quick positioning and weight adjustment during balance adjustment. Several alloy columns 10 are fixedly connected to the bottom of the outer wall of the support platform 1, serving as basic load-bearing units to ensure the overall stability of the support platform 1. The counterweight blocks 11 are rigidly connected to the outer wall of the counterweight grooves 9. The counterweight blocks 11 offset the unbalanced torque between the workpiece and the tooling by increasing or decreasing their weight, ensuring smooth and safe operation. The counterweight grooves 9 are symmetrically arranged along the central axis of the support platform 1 to optimize weight distribution efficiency. The workpiece to be plated 12 is fixedly installed on the bottom of the outer wall of the support platform 1. The workpiece to be plated 12 is the workpiece that needs to be heat treated. The bottom of the outer wall of the limiting plate 306 is rigidly connected to the top of the outer wall of the workpiece to be plated 12, forming a vertical support for the workpiece. The direct limit prevents displacement during processing. The alloy column 10 adopts a uniform distribution design to improve the load balance of the support platform 1. The inner wall of the counterweight groove 9 is provided with anti-slip texture to enhance the positioning accuracy of the counterweight block 11. A buffer layer is provided on the contact surface between the workpiece to be plated 12 and the limiting plate 306 to reduce assembly impact. A guide slope is provided at the opening end of the counterweight groove 9 to facilitate the quick insertion of the counterweight block 11. The limiting plate 306 adopts a lightweight hollow structure to reduce the overall weight while ensuring strength. The bottom of the alloy column 10 integrates an anti-slip pad to increase the friction with the contact surface. The support platform 1 achieves dynamic balance adjustment through the modular combination of the counterweight groove 9 and the counterweight block 11. With the coordinated constraint of the workpiece to be plated 12 and the limiting plate 306, a multi-dimensional stable control system is formed.

[0047] Working principle: First, when adding a counterweight 11 to the counterweight slot 9, the rotating screw 402 drives the sliding column 603 to move along the longitudinal sliding trajectory, thereby causing the lower pressure seat 604 to move upward to the unlocking height. Then, manually pull the rod 202 until the limit ring 204 is completely released from the constraint. By rotating the limit ring 204, it forms a locking engagement with the preset slot on the surface of the rod 202. At this time, the counterweight slot 9 is in an open state, and the newly added counterweight 11 can be easily inserted. The fixing operation is executed in reverse. Loosen the limit ring 204104 to release it from the slot, release the rod 202, and it automatically resets under the action of the elastic element, synchronously reversing the process. The rotating screw 402 drives the slide column 603 to slide in the opposite direction, pushing the lower pressure seat 604 downward to the preset pressure point. The counterweight 11 is pressed by the synergistic action of the thread self-locking characteristic and the downward pressure. This structure is controlled by the axial movement of the slide column 603 and the rotational locking of the limit ring 204, realizing the rapid switching between dynamic unlocking and static locking during the loading and unloading of the counterweight 11. The pressure surface of the lower pressure seat 604 adopts a corrugated design to enhance friction. The groove edge of the limit ring 204 is provided with a guide chamfer to reduce assembly resistance. The thread profile of the screw 402 adopts a trapezoidal structure to improve efficiency. The whole set takes into account both the ease of operation and the reliability of fixation.

[0048] Furthermore, by pulling the pin strip 305 within the second slot 304, it forms a locking constraint with the workpiece 12 to be plated. This, combined with the top limiting plate 306 and the bottom support plate 303, performs dual limiting to ensure that the workpiece 12 is free from displacement during processing. This structure, through the continuous sliding adjustment of the pin strip 305 within the second slot 304, is compatible with the assembly requirements of workpieces of different thicknesses. The contact surface of the support plate 303 adopts a stepped planar design, which, combined with the variable clamping area of ​​the limiting plate 306, achieves an adaptive fixing mode. The bottom surface of the limiting plate 306 integrates anti-slip texture to enhance the friction locking effect with the workpiece 12 to be plated. The guide groove of the second slot 304 is equipped with bidirectional limiting marks to precisely control the displacement stroke of the pin strip 305.
