Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a heavy truck control arm machining device. Background Technology

[0002] Heavy truck control arms are generally left and right parts. Current machining methods mostly use horizontal four-axis machining centers, which require fixtures to position and clamp the blanks to ensure uniform machining allowances and consistent precision on all surfaces.

[0003] Traditional machining equipment is time-consuming and labor-intensive in the alignment process, and the movement and resonance of parts are prone to occur during processing, resulting in defective products. Utility Model Content

[0004] The present invention aims to provide a heavy truck control arm processing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heavy-duty truck control arm processing device includes a device body, a lifting ring head screw threadedly connected to the device body, a V-block, a positioning support assembly, an adjustable support, and a clamping mechanism connected to the device body, an adjusting bolt threadedly connected to the V-block, a limit block threadedly connected to the adjusting bolt, a double-ended bolt threadedly connected to the device body, a thin nut threadedly connected to the double-ended bolt, the thin nut cooperating with the device body, a pressure plate slidably connected to the double-ended bolt, a spring and a washer sleeved on the double-ended bolt, the spring being connected at both ends to the thin nut and the washer respectively, a fixing nut threadedly connected to the double-ended bolt, the fixing nut cooperating with the pressure plate, a stud connected to the pressure plate, a stud slidably connected to the device body, a limit nut threadedly connected to the stud, and a limit nut cooperating with the device body.

[0007] Preferably, the positioning support assembly includes a screw and a support block, the device body is connected to a vertical plate, the screw is threadedly connected to the vertical plate, and the support block is connected to the screw.

[0008] Preferably, the adjustable support includes a second screw and a support block, the second screw being threadedly connected to the device body, and the support block being connected to the second screw.

[0009] Preferably, screw one and screw two are threadedly connected with positioning nuts, and the two positioning nuts respectively cooperate with the upright plate and the device body.

[0010] Preferably, the device body is fixed to the worktable of the processing equipment by screws.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] (1) This solution, by setting up V-blocks, adjustable supports, adjusting bolts, and limit blocks, can quickly calibrate the left and right positions according to the blank size. The V-blocks and adjustable supports synchronously achieve front-to-back and up-and-down positioning, transforming the original manual alignment into a standardized adjustment operation, completely changing the clamping mode that "relies on experience and is time-consuming and labor-intensive," and significantly reducing labor intensity. By setting up a clamping mechanism, when the fixing nut is tightened, the spring generates elastic deformation, causing the pressure plate to clamp the part with uniform pressure. This achieves adaptive compensation for the unevenness of the blank surface, avoids part deformation caused by rigid clamping, and absorbs cutting vibration through the buffering effect of the spring, effectively reducing resonance during processing, and firmly fixing the part to the device body, avoiding scrap due to inaccurate positioning. By setting up studs and limit nuts, the limit nuts can limit the lowest position of the pressure plate, preventing excessive clamping from damaging the part, and fixing the pressure plate when not clamped, ensuring operational safety. Secondly, the device body can simultaneously clamp two control arms, left and right. Through the coordinated action of V-blocks, limit blocks and adjustable supports, the two parts are positioned and clamped synchronously. Compared with traditional single-piece clamping, this greatly saves clamping time and significantly improves processing efficiency.

[0013] (2) By setting up a positioning support component, the support block can be adjusted along the screw to form multi-point support after contacting the non-machined surface of the control arm, preventing the parts from tilting or shifting during processing, and is especially suitable for the stable support of asymmetrical blanks.

[0014] (3) By setting an adjustable support, when the support block is against the control arm, the support block can be precisely adjusted by rotating the screw two to make the allowance of each machining surface evenly distributed, avoiding cutting vibration or machining scrap caused by uneven allowance, and ensuring the consistency of machining accuracy from the source.

[0015] (4) By setting a positioning nut, after adjusting to the appropriate position, tightening the positioning nut can lock the screw, prevent position displacement caused by vibration during processing, ensure the stability of the support block and the support block, and improve the reliability of the overall structure of the fixture.

[0016] (5) The device body is fixed to the worktable of the processing equipment by screws, and the installation interface is standardized, which can be quickly adapted to mainstream equipment such as horizontal four-axis machining centers without the need to modify the machine tool. The lifting ring head screw is threaded to the device body, which facilitates the lifting and transportation of the fixture and reduces the labor cost of equipment debugging and maintenance.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] like Figure 1-2 The heavy-duty truck control arm processing device shown includes a device body 7. Both ends of the top of the device body 7 are symmetrically threaded with lifting ring screws 8, facilitating the overall lifting of the fixture onto the processing equipment's worktable using a lifting device. Each end of the device body 7 is symmetrically connected to two V-blocks 16, two positioning support components, five adjustable supports, and five clamping mechanisms. Each V-block 16 is threaded with an adjusting bolt 15, and each adjusting bolt 15 is threaded with a limit block 14. The arc surface of the V-block 16 contacts the bottom arc surface of the control arm blank, forming a positioning reference in the front-to-back direction. The limit block 14, through the extension and retraction adjustment of the adjusting bolts 15, conforms to the end face of the part, achieving precise positioning in the left-to-right direction. The combined effect of these two mechanisms ensures the part's position is fixed on the horizontal plane. The clamping mechanism includes a double-ended bolt 12, which is threadedly connected to the device body 7. A thin nut 13 is threadedly connected to the double-ended bolt 12, and the thin nut 13 cooperates with the device body 7. A pressure plate 10 is slidably connected to the double-ended bolt 12. A spring 11 and a washer 2 are fitted onto the double-ended bolt 12. Both ends of the spring 11 are connected to the thin nut 13 and the washer 2, respectively. A fixing nut 3 is threadedly connected to the outermost end of the double-ended bolt 12, and the fixing nut 3 cooperates with the pressure plate 10. A stud 1 is connected to the pressure plate 10, and the stud 1 is slidably connected to the device body 7. A limit nut 17 is threadedly connected to the stud 1, and the limit nut 17 cooperates with the device body 7. The clamping mechanism ensures that the part is in the correct machining position and that the part is clamped under pressure during processing, thus completing the part clamping. When the outermost fixing nut 3 is tightened, the spring 11 is compressed and undergoes elastic deformation, transmitting pressure to the pressure plate 10 through the washer 2, causing the pressure plate 10 to press the surface of the part with uniform force. The elasticity of spring 11 can adaptively compensate for unevenness on the blank surface, avoiding deformation of the parts caused by rigid clamping, while absorbing vibration during the cutting process and reducing resonance. The limiting nut 17 on the stud 1 can limit the lowest position of the pressure plate 10 to prevent excessive clamping and damage to the parts; when no parts are clamped, the limiting nut 17 can fix the pressure plate 10 to prevent it from shaking and ensure operational safety.

[0022] like Figure 2As shown, the positioning support assembly includes a screw 19 and a support block 18. The device body 7 is connected to a vertical plate 9 corresponding to the support block 18. The screw 19 is threadedly connected to the corresponding vertical plate 9, and the support block 18 is connected to the corresponding screw 19. When the support block 18 contacts the non-machined surface of the control arm, the positioning nut 6 on the screw 19 is tightened to lock the position of the support block 18. After contacting the non-machined surface of the control arm, it forms an auxiliary support point. The auxiliary V-block 16 and the limiting block 14 realize the three-dimensional positioning of the part and prevent the part from moving during processing.

[0023] like Figure 1 As shown, the adjustable support includes a second screw 5 and a support block 4. The second screw 5 is threadedly connected to the device body 7, and the support block 4 is connected to the second screw 5 to ensure the overall machining allowance of the part. By rotating the second screw 5, the position of the support block 4 is adjusted to make the allowance of each machined surface uniform, avoiding sudden changes in cutting force or machining failure due to uneven allowance. After adjustment, the positioning nut 6 on the second screw 5 is tightened to fix the position of the support block 4, ensuring the stability of allowance distribution during machining.

[0024] like Figure 1 , 2 As shown, screw 19 and screw 5 are threadedly connected to positioning nuts 6, which respectively cooperate with the vertical plate 9 and the device body 7. The bottom of the device body 7 is fixed to the worktable of the processing equipment by screws, forming a rigid connection to ensure the positional stability of the device body 7 during processing and avoid positioning offset caused by vibration. The symmetrical structure at both ends of the device body 7 allows for the simultaneous clamping of two control arms. Through the synergistic action of the V-blocks 16, limit blocks 14, positioning support components, adjustable supports, and clamping mechanisms on both sides, the synchronous positioning and clamping of the two parts are achieved, saving half the clamping time compared to traditional single-piece clamping, significantly improving processing efficiency and adapting to batch production needs. The symmetrically distributed components ensure that the device body 7 is subjected to uniform force, reducing the risk of deformation caused by unilateral force; the standardized setting of each adjustment component allows for quick adaptation to blanks of different sizes by rotation, without the need to change the fixture, enhancing the versatility of the fixture and its adaptability to blank tolerances.

[0025] The specific implementation process is as follows:

[0026] First, the device body 7 is hoisted onto the worktable of the horizontal four-axis machining center using the hoisting ring screw 8. The bottom screws rigidly fix the device body 7 to the worktable, ensuring accurate positioning in the machining coordinate system. The left and right control arm blanks are placed at both ends of the device body 7, with the bottom arc surface of the blanks aligning with the arc surface of the V-block 16, forming a positioning reference in the front-back direction. Simultaneously, the adjusting bolt 15 on the V-block 16 is rotated to push the limit block 14 against the end face of the part. The left and right positions of the part are finely adjusted by adjusting the extension and retraction of the adjusting bolt 15, ensuring that the projection of the part on the horizontal plane is aligned with the machining coordinate system. Then, the screw 2 5 is rotated to bring the support block 4 into contact with the blank. After adjustment, the positioning nut 6 on the screw 2 5 is tightened to fix the position of the support block 4. Rotate screw 19 to make support block 18 slightly contact the non-machined surface of the blank. At this time, support block 18, V-block 16, limit block 14, and adjustable support form a four-point support structure. Tighten positioning nut 6 to lock the position of support block 18 and support block 4 to prevent the part from tilting or vibrating in the vertical direction. Finally, pass the stud 1 of pressure plate 10 through the through hole of device body 7 so that pressure plate 10 corresponds to the part of the blank that needs to be pressed. Insert thin nut 13, spring 11, and washer 2 onto double-ended bolt 12 in sequence. Screw double-ended bolt 12 into the threaded hole of device body 7, with thin nut 13 abutting against the top surface of device body 7. Tighten fixing nut 3 to compress spring 11 and generate elastic force, pressing pressure plate 10 downward to press against the surface of blank, ensuring that pressure plate 10 fits the blank evenly.
