Description

Technical Field

[0001] This utility model relates to the field of forging technology, specifically to a clamping device for forging trailer hook machining. Background Technology

[0002] The trailer hitch is an important component of a car. When a car is unable to move normally due to a malfunction and needs to be towed, the trailer hitch plays a role in traction and fixation.

[0003] like Figure 1 The trailer hook formed by forging includes a connecting rod 1, a shank 2, a ball head 3, and a hook tail 4. One end of the connecting rod 1 is fixed to one end of the shank 2, and the other end of the shank 2 is fixed to the ball head 3. A first angle is formed between the connecting rod 1 and the shank 2. The other end of the connecting rod 1 is fixed to the hook tail 4. A second angle is formed between the connecting rod 1 and the hook tail 4. Pins 5 are provided on both sides of the hook tail 4, and an assembly hole 6 is provided on the side wall of the other end of the connecting rod 1.

[0004] After the aforementioned trailer hook is forged, the surface roughness of the shank 2 and ball head 3 needs to reach a set value. Therefore, the shank 2 and ball head 3 are machined. During machining, the trailer hook needs to be fixed. However, the aforementioned trailer hook is an irregularly shaped structural part. Therefore, conventional clamping fixtures cannot clamp and fix the trailer hook. Therefore, the current task is to design a new clamping device to clamp the trailer hook. Utility Model Content

[0005] This utility model provides a clamping device for machining forged trailer hooks, which features convenient and stable clamping of trailer hooks.

[0006] The technical solutions to the above technical problems are as follows:

[0007] A clamping device for forging trailer hook machining includes a base and a first fixed seat, wherein the base and the first fixed seat are fixed together, characterized in that it further includes:

[0008] The first mounting base is fixed to the first fixing base;

[0009] The first clamping unit clamps one end of the connecting rod and slides with the first mounting base;

[0010] The second fixing seat is fixed to the base, and the second fixing seat is provided with the first bolt;

[0011] The third fixed seat is fixed to the base, and a receiving space is formed between the third fixed seat and the second fixed seat to accommodate the other end of the connecting rod. The third fixed seat is provided with a positioning hole for inserting a pin shaft. The side wall of the third fixed seat facing the second fixed seat is provided with a support component that mates with the assembly hole on the side wall of the other end of the connecting rod.

[0012] The first clamping unit includes a first slider, a second slider, a screw, a first clamping block, and a second clamping block. The first slider and the second slider are slidably engaged with the first mounting base. The screw has a first threaded section and a second threaded section with opposite directions of rotation. The first threaded section is threadedly connected to the first slider, and the second threaded section is threadedly connected to the second slider. The first clamping block is fixed to the first slider, and the second clamping block is fixed to the second slider.

[0013] Furthermore, the screw has a smooth rod section, a first positioning step, and a second positioning step. The two sides of the smooth rod section are the first positioning step and the second positioning step, respectively. A second support component is provided on the first mounting base. The second support component is provided with an assembly groove. After the smooth rod section and the assembly groove are fitted with a clearance, the second support component is clamped between the first positioning step and the second positioning step.

[0014] Furthermore, the first clamping unit also includes a first adjusting screw and a second adjusting screw, the first adjusting screw being threadedly connected to the first clamping block and the second adjusting screw being threadedly connected to the second clamping block.

[0015] The process of clamping the forged trailer hook using this invention is as follows: One end of the connecting rod is placed between the first and second clamping blocks, and the other end of the connecting rod is placed into the receiving space. After the mounting hole mates with the supporting component and the pin mates with the positioning hole, the first bolt is rotated, causing it to abut against the connecting rod and clamp the other end of the connecting rod. The screw is then rotated, driving the first and second sliders to move. Consequently, the first clamping block follows the first slider, and the second slider follows the second clamping block, thus clamping one end of the connecting rod between the first and second clamping blocks. Because the forged trailer hook is relatively long, it may warp. To improve the clamping accuracy of the clamping device, the first and second adjusting screws are rotated, causing the first adjusting screw to mate with the first sidewall of the connecting rod, and the second adjusting screw to mate with the second sidewall of the connecting rod. Through the action of the first and second adjusting screws, the position of the connecting rod is finely adjusted, thereby ensuring that the center of the forged trailer hook matches the machine tool. Therefore, it can be seen that the clamping operation of the forged trailer hook of this utility model is not only simple and convenient, but also has high positioning accuracy, which is conducive to improving the subsequent processing accuracy.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, the clamping device for forging trailer hook machining of this utility model includes a base 11, a first fixed seat 12, a first mounting seat 13, a first clamping unit, a second fixed seat 14, and a third fixed seat 16. The base 11 is fixed to the first fixed seat 12, and the first mounting seat 13 is fixed to the first fixed seat 12. The first fixed seat 12 is provided with a notch. After the first mounting seat 13 and the notch on the first fixed seat 12 are engaged, the first fixed seat 13 is fixed to the first fixed seat 12.

[0026] The first clamping unit clamps one end of the connecting rod 1. The first clamping unit is slidably engaged with the first mounting base 13. The first mounting base 13 is provided with a groove 13c and a sliding groove 13d. The first clamping unit includes a first slider 20, a second slider 21, a screw 22, a first clamping block 23, and a second clamping block 24. The first slider 20 and the second slider 21 are slidably engaged with the first mounting base 13. A portion of the first slider 20 and the second slider 21 are located in the groove 13c. The first slider 20 and the second slider 21 are slidably engaged with the sliding groove 13d. The other portion of the first slider 20 and the second slider 21 are located outside the groove 13c. The first slider 20 and the second slider 21 are also slidably engaged with the end face of the first mounting base 13.

[0027] The screw 22 has a first threaded section 22a and a second threaded section 22b, with opposite directions of rotation. The first threaded section 22a is threadedly connected to the first slider 20, and the second threaded section 22b is threadedly connected to the second slider 21. The screw 22 also has a smooth section 22c, a first positioning step 22d, and a second positioning step 22e. The first positioning step 22d and the second positioning step 22e are located on either side of the smooth section 22c. A second support member 13a is provided on the first mounting base 13, located within a groove 13c. The second support member 13a has an assembly groove 13b. After the smooth section 22c and the assembly groove 13b are fitted with a clearance fit, the second support member 13a is clamped between the first positioning step 22d and the second positioning step 22e. Engaging the screw 22 with the second support member 13a prevents axial movement of the screw 22.

[0028] The first clamping block 23 is fixed to the first slider 20 by connecting screws. The second clamping block 24 is fixed to the second slider 21 by connecting screws. Since the first clamping block 23 and the second clamping block 24, together with the screw 22 and the first mounting base 13, respectively form a screw mechanism, when the screw 22 is rotated, it drives the first slider 20 and the second slider 21 to move. Consequently, the first clamping block 23 moves with the first slider 20, and the second slider 21 moves with the second clamping block 24.

[0029] The first clamping unit also includes a first adjusting screw 25 and a second adjusting screw 26. The first adjusting screw 25 is threadedly connected to the first clamping block 23, and the second adjusting screw 26 is threadedly connected to the second clamping block 24. A first threaded hole is provided on the first clamping block 23, and a second threaded hole is provided on the second clamping block 24. The first adjusting screw 25 is threadedly connected to the first threaded hole on the first clamping block 23, and the second adjusting screw 26 is threadedly connected to the second threaded hole on the second clamping block 24. The position of the forged trailer hook can be finely adjusted using the first adjusting screw 25 and the second adjusting screw 26, thereby improving the clamping accuracy of the forged trailer hook.

[0030] The second fixing seat 14 is fixed to the base 11. The second fixing seat 14 is provided with the first bolt 15. The third fixing seat 16 is fixed to the base 11. A receiving space 17 is formed between the third fixing seat 16 and the second fixing seat 14 to receive the other end of the connecting rod 1. The third fixing seat 16 is provided with a positioning hole 18 for inserting the pin shaft 5. The side wall of the third fixing seat 16 facing the second fixing seat 14 is provided with a support component 19 that mates with the assembly hole 6 on the side wall of the other end of the connecting rod 1.

[0031] The process of clamping the forged trailer hook using this utility model is as follows: one end of the connecting rod 1 is placed between the first clamping block 23 and the second clamping block 24, and the other end of the connecting rod 1 is placed into the receiving space 17, so that the assembly hole 6 is engaged with the support component 19 and the pin 5 is engaged with the positioning hole 18. Then, the first bolt 15 is rotated so that the first bolt 15 and the connecting rod form abutment, clamping the other end of the connecting rod 1. The screw 22 is rotated, which drives the first slider 20 and the second slider 21 to move. Then, the first clamping block 23 moves with the first slider 20, and the second slider 21 moves with the second clamping block 24. One end of the connecting rod 1 is clamped between the first clamping block 23 and the second clamping block 24. Because the forged trailer hook is relatively long, it will warp. In order to improve the clamping accuracy of the clamping device, the first adjusting screw 25 and the second adjusting screw 26 are rotated so that the first adjusting screw 25 engages with the first side wall of the connecting rod 1 and the second adjusting screw 26 engages with the second side wall of the connecting rod 1. Through the action of the first adjusting screw 25 and the second adjusting screw 26, the position of the connecting rod 1 is finely adjusted, thereby ensuring that the center of the forged trailer hook matches the machine tool.
