Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, and in particular to a modular combination fixture frame. Background Technology

[0002] With the continuous development of modern automobile manufacturing technology, the level of automation in production lines is increasing, and the requirements for precision and efficiency are becoming more stringent. In the automobile production process, the frame structure, as a key component for supporting and positioning workpieces, plays a crucial role. To ensure the stability and accuracy of workpieces during production, multiple combination fixtures are typically installed on the frame for multi-point positioning and fixation of the workpieces.

[0003] However, most existing automotive production line frames are connected by welding, bolting, or riveting. Welding can provide strong connection strength and is suitable for high load requirements, but after long-term use, the connection points are prone to deformation or cracks. Bolted connections are prone to loosening after long-term use, affecting the overall stability. Utility Model Content

[0004] Therefore, it is necessary to provide a modular combination fixture frame to address the problem that the connection method of traditional combination fixture frames is prone to stability reduction after long-term use.

[0005] A modular combination clamp frame includes: a frame body, the frame body being composed of multiple support rods; Fastening assembly, wherein the fastening assembly is disposed at the connection point of two support rods in the frame body; The fastening assembly includes a support rod disposed on one side of the support rod, and a pressure rod disposed on one side of the support rod.

[0006] In one embodiment, the fastening assembly further includes a sleeve disposed on the surface of one of the support rods and a U-shaped tube disposed on the surface of the other support rod. One end of the pressure rod is movably connected to the U-shaped tube via a pivot, and the side of the support rod near the U-shaped tube is movably connected to the U-shaped tube via a pivot.

[0007] In one embodiment, a through groove is formed on the surface of the support rod, and a threaded sleeve is provided in the through groove of the support rod through a bearing, and a lead screw is threadedly connected to the threaded sleeve.

[0008] In one embodiment, the other end of the lead screw is designed as a hook, and the hook portion of the lead screw is hooked to the sleeve.

[0009] In one embodiment, a pressure block is movably connected between the opposite ends of two pressure rods via a pivot, and a first bolt is threaded into the internal thread of the pressure block, which is threaded into another support rod.

[0010] In one embodiment, both the sleeve and the U-tube have slotted holes on their surfaces, and a second bolt is inserted into each of the two sets of slotted holes. The two sets of bolts are threadedly connected to one of the support rods and the other support rod, respectively.

[0011] In one embodiment, the sleeve and the two U-shaped tubes are arranged in a triangle.

[0012] Beneficial effects 1. When workers need to connect and assemble the support rods of the frame body, the sleeve, U-tube, strut, pressure rod and second bolt can help the workers to pre-position the two support rods, improving the convenience of operation; 2. When the first bolt is screwed in, the pressure rod squeezes the U-shaped tube, and the U-shaped tube supports and pulls the support rod. This allows the sleeve and the two U-shaped tubes to pull each other, improving the stability and tightness between the support rods. At the same time, it can also pull the second bolt, so that the second bolt abuts against the mounting hole of the support rod, thereby increasing the friction between the bolt and the mounting hole and reducing the loosening of the second bolt during use.

[0021] The following is combined Figures 1-4 This invention describes a modular combination clamp frame.

[0022] In one embodiment, a modular combination clamp frame includes: a frame body 1, which is composed of multiple support rods; Fastening component 2 is located at the connection point of two support rods in the frame body 1; like Figure 2 , Figure 3 and Figure 4 As shown, the fastening assembly 2 includes a support rod 202 disposed on one side of the support rod, and a pressure rod 204 disposed on one side of the support rod 202; the fastening assembly 2 also includes a sleeve 201 disposed on the surface of one of the support rods and a U-shaped tube 203 disposed on the surface of the other support rod, one end of the pressure rod 204 is movably connected to the U-shaped tube 203 via a pivot, and the side of the support rod 202 near the U-shaped tube 203 is movably connected to the U-shaped tube 203 via a pivot; a pressure block is movably connected between the opposite ends of the two pressure rods 204 via a pivot, and a first bolt 205 is threadedly connected to the inside of the pressure block, and the first bolt 205 is threadedly connected to the other support rod; First, the worker places the sleeve 201 onto the surface of one of the support rods. Then, two U-shaped tubes 203 are placed on either side of the other support rod. Next, the hook of the threaded rod 207 is hooked onto the side of the sleeve 201. At this point, the worker inserts the second bolt into the slots of the sleeve 201 and U-shaped tubes 203, extending it into the corresponding support rod mounting holes. The second bolt does not need to be tightened at this stage. Then, the worker inserts the first bolt 205 into the pressure block, extending it into the support rod mounting hole of the U-shaped tube 203, and tightens the first bolt 205. Bolt 205 will compress the pressure block, which will then apply pressure to the two pressure rods 204. The two pressure rods 204 will push the two U-shaped tubes 203 to opposite sides. At this time, the U-shaped tubes 203 will pull the support rods 202 to move the sleeves 201 upward, so that the support rods of the sleeves 201 and the support rods of the U-shaped tubes 203 are tightly abutted. This completes the effect of pre-positioning the two support rods. Then, the second bolt is tightened so that the second bolt positions the U-shaped tubes 203 and the sleeves 201, thus completing the modular combination effect of the frame body 1. Both the sleeve 201 and the U-shaped tube 203 have slotted holes on their surfaces. A second bolt is inserted into each of the two sets of slotted holes. The two sets of bolts are threaded to one of the support rods and the other support rod, respectively. The sleeve 201 and the two U-shaped tubes 203 are arranged in a triangular configuration. By tightening the first bolt 205, the pressure rod 204 pushes the two U-shaped tubes 203 to both sides, and with the help of the threaded sleeve 206, the screw rod 207 pulls the sleeve 201 upward, so that the sleeve 201 and the two U-shaped tubes 203 can pull each other, ensuring the stability and support strength between the two support rods. The surface of the support rod 202 is provided with a through groove, and a threaded sleeve 206 is provided in the through groove of the support rod 202 through a bearing. A lead screw 207 is threadedly connected to the threaded sleeve 206. The other end of the lead screw 207 is designed with a hook shape, and the hook part of the lead screw 207 is hooked to the sleeve 201. Finally, the operator can also tighten the threaded sleeve 206, which drives the end of the screw 207 to pull the sleeve 201, thereby further promoting the tightness of the fit between the two support rods. At the same time, the sleeve 201 can also abut against the second bolt to increase the friction between the second bolt and the mounting hole and reduce the phenomenon of bolt loosening. In the automotive production line, the clamping, fixing and transfer of workpieces are key steps to ensure the smooth operation of the production process. Automotive parts have different shapes and sizes, and most parts are quite heavy. Therefore, clamping and fixing are necessary to ensure their stability and accuracy during processing, assembly and handling. As a result, combination fixtures are widely used in the production line. Combination fixtures, through the cooperation of multiple clamping devices with the frame, can effectively position and fix the workpiece at multiple points. They not only ensure the accuracy of the workpiece during the processing, but also enable operators to quickly and conveniently change the workpiece, thereby improving production efficiency. The design of combination fixtures can usually be flexibly adjusted to adapt to different workpiece specifications and shapes, thereby ensuring the efficient operation of the production line. The frame of the combined fixture is usually composed of multiple structural units, which are usually connected by welding, bolting or riveting. Before the frame is assembled, the personnel need to assemble each structure in the corresponding position. The fastening component 2 mentioned above can not only assist in the pre-connection between two adjacent structures, but also fasten the structures together. Therefore, whether the frame is welded, bolted or riveted, the fastening component 2 can ensure the overall strength of the frame body 1. Furthermore, the fastening component 2 is set between multiple structures of the frame body 1 and will not affect the fixture device on the surface of the frame body 1.

[0023] Working principle: In actual use, the operator first places the sleeve 201 on the surface of one of the support rods, then places two U-shaped tubes 203 on both sides of the surface of the other support rod. Next, the hook of the threaded rod 207 is hooked onto the side of the sleeve 201. At this point, the operator inserts the second bolt into the slots of the sleeve 201 and U-shaped tubes 203 respectively, extending it into the corresponding support rod mounting holes. Then, the operator inserts the first bolt 205 into the pressure block, extending it into the support rod mounting hole of the U-shaped tube 203, and tightens the first bolt 205. The pressure block is then pressed, which applies pressure to the two pressure rods 204. The two pressure rods 204 push the two U-shaped tubes 203 to opposite sides. The U-shaped tubes 203 then pull the support rods 202, causing the sleeves 201 to move upwards, so that the support rods of the sleeves 201 and the support rods of the U-shaped tubes 203 are tightly abutted. This completes the pre-positioning effect of the two support rods. Then, the second bolt is tightened, so that the second bolt positions the U-shaped tubes 203 and the sleeves 201, thus completing the modular combination effect between the support rods in the frame body 1.
