Abstract
Description
Technical Field
[0001] This utility model relates to the field of support arm processing technology, specifically a support arm multi-hole synchronous processing equipment. Background Technology
[0002] A trailing arm, generally speaking, refers to a component in a vehicle's suspension system used to connect the wheels to the vehicle body. Its function is to transmit the forces and torques from the wheels to the vehicle body and to bear the vehicle's weight and various loads during driving. There are many types of trailing arms, and their design must consider strength, stiffness, and kinematic characteristics to ensure vehicle handling and ride comfort. Different vehicle models and suspension types use different trailing arm structures and materials. Trailing arms are generally made of cast aluminum alloy and are connected to other suspension components via bolts and openings in their surface.
[0003] The existing Chinese utility model patent with publication number CN204975443U discloses an automatic drilling device for a motorcycle rocker arm, including a base. The device is characterized by: a positioning mold for placing a rocker arm to be processed on the base; a side opening on the inner side of the positioning mold; a stop block on the inner side of the positioning mold for covering the side opening; a first drive motor driving the stop block towards the side opening; a through hole on the upper side of the positioning mold leading to the interior of the side opening; and a drilling mechanism located directly above the through hole. The drilling mechanism includes a second drive motor with its output shaft vertically downwards towards the through hole; a drill bit coaxially mounted on the output shaft of the second drive motor; and a gear fixedly mounted on one side of the second drive motor.
[0004] To prevent the support arm from shifting during drilling, a clamp is needed to limit its position. However, the limiting effect is poor due to the shape of the support arm. Furthermore, opening and closing the clamp requires manual operation, which is very cumbersome. In addition, the support arm surface needs multiple openings to connect to other components. Existing processing equipment generally uses slide rails to adjust the position of individual drill bits and drill holes one by one, which is inefficient. Utility Model Content

[0014] Beneficial effects
[0015] This utility model provides a device for simultaneous processing of multiple circular holes in a support arm. Compared with the prior art, it has the following advantages:
[0016] (1) The multi-hole synchronous processing equipment for the support arm is equipped with a limit motor. The limit motor is fixedly installed on the front side of the movable block. The rear end of the shaft of the limit motor is fixedly installed with a lead screw. The lead screw is connected to the movable block through a threaded structure. The parting vise is installed symmetrically on the front and rear sides above the limit block and the movable block. When the limit motor drives the lead screw to rotate, the lead screw will adjust the spacing of the parting vise according to the rotation direction, so that the parting vise clamps the support arm. The final parting of the parting vise can contact the outer edge of the support arm, increasing the contact surface between the support arm and the parting vise.

By rotating, the straight line connecting the two openings of the support arm is adjusted to be parallel to the slide rail, so that the line connecting the opening positions of the support arm and the line connecting the drill chuck are kept horizontal. Then, the position of the base is adjusted by the cross slide groove, so that the opening position on the rear side of the support arm is directly below the drill chuck at the rear end of the slide rail. The movement direction of the front fixed frame is restricted by the slide rail, so that the position between the drill chucks is always in the same straight line. The piston is connected to the fixed frame, and the distance between the fixed frames is adjusted by adjusting the extension and retraction of the piston, so that the movable drill chuck can be directly above the opening position on the front side of the support arm. Then, the support arm is moved upward by the lifting platform to drill. This method can improve the drilling efficiency when processing multiple holes. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This utility model provides a technical solution: a multi-round hole synchronous processing equipment for a support arm, including a lifting platform 1, a limiting mechanism 2 for limiting the position of the support arm fixedly installed above the lifting platform 1, and a drilling mechanism 3 for drilling fixedly installed above the lifting platform 1.
[0026] The limiting mechanism 2 includes a cross slide 21 fixed above the lifting platform 1. A base 22 is fixedly installed on the top of the cross slide 21. A pressure bearing 23 is fixedly installed above the base 22. A turntable 24 is fixedly installed above the pressure bearing 23. A limiting block 25 is fixedly installed above the turntable 24. A movable block 26 is inserted through one end of the limiting block 25. A limiting motor 27 is fixedly installed on the front side of the limiting block 25. A lead screw 28 is fixedly installed at the rear end of the shaft of the limiting motor 27. A parting vise 29 is fixedly installed above the limiting block 25 and the movable block 26. The turntable 24 is rotatably connected to the base 22 through the pressure bearing 23. The bottom of the movable block 26 contacts the turntable 24. The movable block 26 is rotatably connected to the limiting block 25. The lead screw 28 is rotatably connected to the movable block 26 through a threaded structure. The parting vise 29 is symmetrically installed above the limiting block 25 and the movable block 26.
[0027] Specifically, the lifting platform 1 can adjust the height of the parting vise 29 to facilitate contact between the support arm and the drill bit. The position of the base 22 can be adjusted via the cross groove 21 to facilitate the adjustment of the support arm position. The pressure bearing 23 facilitates the rotation of the turntable 24. By rotating, the straight line connecting the two openings of the support arm is adjusted to be parallel to the slide rail 32, so that the support arm can be drilled simultaneously. The moving direction and rotation angle of the movable block 26 are restricted by the limit block 25. Since the lead screw 28 is connected to the movable block 26 through the threaded structure, when the limit motor 27 drives the lead screw 28 to rotate, the lead screw 28 will adjust the spacing of the parting vise 29 according to the rotation direction, so that the parting vise 29 clamps the support arm. The final parting of the parting vise 29 can contact the outer edge of the support arm, increasing the contact surface between the support arm and the parting vise 29. In addition, the lead screw 28 has a certain self-locking effect, thereby improving the fixing effect and preventing the support arm from moving during the drilling process.
[0028] The drilling mechanism 3 includes support frames 31 mirror-mounted on the left and right sides of the lifting platform 1. A slide rail 32 is fixedly mounted on the top of the support frame 31. Fixing frames 33 are mounted on the front and rear sides of the slide rail 32. An adjusting piston 34 is fixedly mounted between the fixing frames 33. The fixing frames 33 are mirror-symmetrically mounted on the front and rear sides of the slide rail 32. The rear fixing frame 33 of the slide rail 32 is fixedly connected to the slide rail 32 by bolts, and the front fixing frame 33 of the slide rail 32 is slidably connected to the slide rail 32 by a slider. The two ends of the adjusting piston 34 are fixedly connected to the fixing frames 33 on the front and rear sides of the slide rail 32, respectively. A sleeve 35 is fixedly mounted on the front side of the rear fixing frame 33 of the slide rail 32. A linear bearing 36 is fitted into the front end of the sleeve 35. The inner end of the linear bearing 36... A limiting shaft 37 is inserted and installed in the middle. A drilling motor 38 is fixedly installed above the fixing frame 33. A drive wheel 39 is fixedly installed on the outside of the rotating shaft of the drilling motor 38. A drill chuck 310 is inserted and installed on one side of the fixing frame 33. A transmission wheel 311 is fixedly installed on the top of the drill chuck 310. A transmission belt 312 is fitted on the outside of the transmission wheel 311. The limiting shaft 37 is slidably connected to the sleeve 35 through a linear bearing 36. The front end of the limiting shaft 37 is fixedly connected to the front fixing frame 33 of the slide rail 32. An opening for the transmission belt 312 to pass through is provided on the central vertical structure surface of the fixing frame 33. An opening for the rotating shaft of the drilling motor 38 to pass through is provided on the top of the fixing frame 33. One end of the transmission belt 312 is fitted on the outside of the drive wheel 39.
[0029] Specifically, the support frame 31 supports the slide rail 32, and the slide rail 32 restricts the movement direction of the front fixed frame 33, ensuring that the positions of the drill chucks 310 are always in a straight line. The adjusting piston 34 is connected to the fixed frame 33, and the distance between the fixed frames 33 is adjusted by adjusting the extension and retraction of the piston 34, so that the two drill chucks 310 can be located directly above the two opening positions for simultaneous drilling. The sleeve 35 and the limiting shaft 37 further restrict the movement direction of the fixed frame 33 to prevent the fixed frame 33 from deviating. The linear bearing 36 reduces the friction between the sleeve 35 and the limiting shaft 37. The cylindrical structure at the top of the drill chuck 310 vertically penetrates the fixed frame 33 and forms a rotatable connection with the fixed frame 33 through the bearing. The drilling motor 38 drives the drive wheel 39 to rotate, and the drive belt 312 drives the drive wheel 311 at the top of the drill chuck 310 to rotate the drill chuck 310. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.
[0030] During operation, the limit motor 27 is fixedly installed on the front side of the movable block 26. A lead screw 28 is fixedly installed at the rear end of the limit motor 27's shaft. The lead screw 28 is rotatably connected to the movable block 26 via a threaded structure. The parting vise 29 is symmetrically installed above the limit block 25 and the movable block 26. When the limit motor 27 drives the lead screw 28 to rotate, the lead screw 28 adjusts the spacing of the parting vise 29 according to the rotation direction, thereby clamping the support arm. The final parting of the parting vise 29 can contact the outer edge of the support arm, increasing the contact surface between the support arm and the parting vise 29. Furthermore, the lead screw 28 has a certain self-locking effect, thus improving the fixing effect and preventing the support arm from moving during drilling. The pressure bearing 23 facilitates the rotation of the turntable 24, allowing adjustment via rotation. The straight line connecting the two openings of the support arm is parallel to the slide rail 32, so that the line connecting the positions where the support arm needs to be opened is horizontal with the line connecting the drill chucks 310. Then, the position of the base 22 is adjusted by the cross slide groove 21 so that the position where the opening needs to be opened on the rear side of the support arm is directly below the drill chuck 310 at the rear end of the slide rail 32. The movement direction of the front fixing frame 33 is restricted by the slide rail 32 so that the positions of the drill chucks 310 are always in the same straight line. The piston 34 is connected to the fixing frame 33. The distance between the fixing frames 33 is adjusted by adjusting the extension and retraction of the piston 34 so that the movable drill chuck 310 can be located directly above the position where the opening needs to be opened on the front side of the support arm. Then, the lifting platform 1 drives the support arm to move upward to drill. This method can improve drilling efficiency when machining multiple holes.
