Description

Technical Field

[0001] This utility model relates to the field of hook tongue heat treatment technology, specifically to an adjustable clamp for hook tongue heat treatment. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which materials, in their solid state, are heated, held at temperature, and cooled to obtain the desired microstructure and properties. Metal heat treatment is one of the important processes in machinery manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape or overall chemical composition of the workpiece, but rather imparts or improves its performance by altering the internal microstructure or the surface chemical composition. To ensure that metal workpieces possess the required mechanical, physical, and chemical properties, in addition to the rational selection of materials and various forming processes, heat treatment is often indispensable. Steel is the most widely used material in the machinery industry. The complex microstructure of steel can be controlled through heat treatment; therefore, the heat treatment of steel is a major aspect of metal heat treatment.

[0003] During the manufacturing process of hook tongues, heat treatment is required to improve their performance. Existing hook tongue fixtures (such as the hook tongue heat treatment hanger with application number 201922150280.5) use a suspension plate mounted on a lifting rod to hold the hook tongues, allowing multiple hook tongues to be suspended simultaneously for heat treatment. However, this method of suspending the hook tongues can lead to workpieces falling during movement or heat treatment, and collisions during movement, resulting in a hook tongue heat treatment failure rate as high as 20%, affecting the quality and efficiency of heat treatment. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an adjustable fixture for hook tongue heat treatment to solve the technical problem that existing hook tongue heat treatment fixtures, which fix the hook tongue by suspension, may cause the workpiece to fall off during movement or heat treatment, and the workpiece may also collide during movement, affecting the heat treatment quality and efficiency of the hook tongue.

[0005] According to the technical solution provided in the embodiments of this application, the adjustable clamp for hook tongue heat treatment includes a basket, on which two sets of clamping mechanisms are arranged side by side and spaced apart;

[0006] The clamping mechanism includes several fixed clamps and several movable clamps. The movable clamps are arranged side by side and screwed to an adjusting rod at intervals, so that the adjusting rod can be rotated to adjust the spacing between the fixed clamps corresponding to the movable clamps, thereby clamping different types of hooks.

[0007] A locking device is simultaneously engaged with the locking groove at the tail end of the adjusting rod and the positioning hole on the fixing plate, thereby locking the adjusting rod.

[0008] Furthermore, a corresponding fixing plate is installed at the bottom of the fixing clamp.

[0009] Furthermore, a corresponding movable plate is installed at the bottom of the movable clamp.

[0010] Furthermore, the base plate is provided with a plurality of adjustment slots, and each adjustment slot is provided with a corresponding sliding groove, so that each movable plate is slidably installed in the adjustment slot by a corresponding slider.

[0011] Furthermore, the two positioning holes are correspondingly disposed on both sides of the fixing plate.

[0012] Furthermore, the locking device includes a locking rod and two positioning rods, the two positioning rods are installed on both sides of the locking rod, and the front ends of the locking rod and the positioning rods are installed on a connecting plate, while a handle is installed at the center of the connecting plate.

[0013] Furthermore, an adjusting wheel is installed on the left side of the adjusting rod.

[0014] Furthermore, corresponding side panels are installed around the base plate via hinges, so that several side panels and the base plate form an upward-opening groove.

[0015] Furthermore, the base plate and the several side panels are provided with several filter holes for the heat treatment liquid to enter the basket.

[0016] In summary, the beneficial effects of this application are as follows:

[0017] 1. By installing two clamping mechanisms with adjustable clamping spacing on the bottom plate of the suspended platform, several movable clamps on the clamping mechanism move along the adjusting groove under the rotation of the adjusting rod, thereby clamping and fixing the hook tongue undergoing heat treatment, replacing the original suspension, preventing the hook tongue from colliding or falling during the heat treatment process, reducing the number of collisions, and thus increasing the hook tongue heat treatment qualification rate to 80%.

[0018] Second, a corresponding locking device is installed at the end of each adjusting rod so that the locking device locks the adjusting rod after the adjustment distance is rotated, preventing the rotating moving plate from moving during the heat treatment of the adjusting rod and causing the clamp to loosen, thereby improving the fixing quality of the clamp on the hook tongue.

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Adjustable clamps for hook-type heat treatment, the structure of which is as follows: Figures 1-5 As shown, the system includes a suspended platform 100, which consists of a base plate 110 and four side panels 120. Each side panel 120 is hinged to the base plate 110, forming an upward-opening groove. This groove is used to house the hooks requiring heat treatment. The base plate 110 and the four side panels 120 have several filter holes to allow the heat treatment liquid to enter the suspended platform 100. The four side panels 120 are connected and secured with pins, facilitating easy disassembly and installation while also providing safety protection.

[0029] like Figure 1 and Figure 4As shown, two sets of clamping mechanisms 130 are arranged side by side and spaced apart on the base plate 110. The two sets of clamping mechanisms 130 increase the number of hooks that can be placed in the basket 100, thereby improving the heat treatment efficiency of the clamps on the hooks.

[0030] like Figure 2 and Figure 4 As shown, the clamping mechanism 130 includes several fixed clamps 131 and several movable clamps 132. The fixed clamps 131 are fixedly mounted on the base plate 110 in parallel and at intervals. The bottom of the fixed clamps 131 is equipped with a corresponding fixed plate 134, and the bottom of the movable clamps 132 is equipped with a corresponding movable plate 135. The movable clamps 132 are screwed onto the adjusting rod 133 in parallel and at intervals. The bottom of each movable clamp 132 is slidably engaged with the sliding groove 112 on the adjusting groove 111 by a slider 136. When the adjusting rod 133 rotates, it drives the movable clamps 132 to move linearly along the corresponding adjusting groove 111, thereby adjusting the distance between each movable clamp 132 and the corresponding fixed clamp 131. This allows the clamp to clamp and fix different types of hooks, thereby improving the practicality of the clamp.

[0031] The locking device 140 includes a locking rod 141 and two positioning rods 142. The two positioning rods 142 are installed on both sides of the locking rod 141, and the front ends of the locking rod 141 and the positioning rods 142 are installed on the connecting plate 143. A handle 144 is installed at the center of the connecting plate 143, and a plum blossom-shaped locking groove 1331 is provided at the center of the tail end of the adjusting rod 133. Corresponding positioning holes 1341 are provided on both sides of the fixing plate 134 on the left side, so that the locking rod 141 and the two positioning rods 142 are simultaneously engaged in the locking groove 1331 at the tail end of the adjusting rod 133 and the positioning holes 1341 on the fixing plate 134, thereby locking the adjusting rod 133 and preventing the adjusting rod 133 from rotating during the heat treatment process, which would cause the moving plate 135 to move and the clamp to loosen, thereby improving the fixing quality of the clamp on the hook tongue.

[0032] The working principle of this utility model is as follows:

[0033] When clamping and fixing the hook tongue that needs to be heat-treated, the traditional method involves placing the hook tongue on a hanging plate for heat treatment. However, the suspended hook tongue may fall or collide with other parts during movement or heat treatment, affecting the heat treatment quality and efficiency. By setting two clamping mechanisms 130 with adjustable clamping distance on the base plate 110 of the hanging basket 100, the rotating adjusting wheel drives the adjusting rod 133 connected to the adjusting wheel to rotate. This causes several movable clamps 132 screwed onto the adjusting rod 133 to move linearly along corresponding adjusting grooves 111, thereby adjusting the distance between each movable clamp 132 and the corresponding fixed clamp 131. This clamps and fixes the hook tongue for heat treatment, replacing the original suspension method. This prevents the hook tongue from colliding or falling during heat treatment, reduces the number of collisions, and increases the hook tongue heat treatment qualification rate to 80%. After adjustment and clamping, the operator will set corresponding locking devices 140 at the tail end of each adjusting rod 133. The locking rod 141 and the two positioning rods 142 are simultaneously engaged in the locking groove 1331 at the tail end of the adjusting rod 133 and the positioning hole 1341 on the fixing plate 134, so that the locking device 140 locks the adjusting rod 133 after the adjustment distance is rotated, preventing the rotating moving plate 135 from moving during the heat treatment of the adjusting rod 133, causing the clamp to loosen, thereby improving the fixing quality of the clamp on the hook tongue.

[0034] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
