Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a mold for processing a transmission case suspension beam. Background Art

[0002] The gearbox suspension beam is a key component of the gearbox suspension system. It is mainly responsible for load-bearing and vibration isolation to protect the gearbox from vibration and impact during vehicle operation.

[0003] Without a transmission cross member, the entire weight of the transmission would be borne by the engine's rear detents, which would place excessive stress and pressure on the engine and its suspension system, leading to engine vibration, increased noise, and premature wear of components.

[0004] In order to reduce configuration, existing cars have reserved holes on the gearbox for mounting the gearbox crossbeam. However, after the gearbox crossbeam is produced, no mounting holes matching the gearbox reserved holes are directly reserved on it. Due to different vehicle models, the positions of the reserved holes on the gearbox are also different. Therefore, in the subsequent processing process, the mounting holes on the crossbeam need to be processed back and forth according to the different gearbox reserved hole models. The existing gearbox crossbeam mounting hole processing method is to drill holes sequentially through rotary drilling equipment, without achieving unified positioning of multiple rotary hole positioning holes and multiple drill bits, resulting in slow drilling efficiency and prone to errors. Utility Model Content

[0005] The purpose of the present utility model is to provide a mold for processing a gearbox suspension beam, so as to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A mold for machining a gearbox suspension crossbeam includes a crossbeam positioning machining workpiece and a rotary hole positioning workpiece for machining and positioning the crossbeam. The crossbeam positioning machining workpiece is connected to the rotary hole positioning workpiece via a driving workpiece. The rotary hole positioning workpiece is located directly above the crossbeam positioning machining workpiece. The driving workpiece is located on one side between the crossbeam positioning machining workpiece and the rotary hole positioning workpiece.

[0008] As a preferred solution of the present invention, the beam positioning processing workpiece includes a positioning seat and a positioning gear located at the top of the beam, the positioning seat is arranged in a hollow U-shaped structure, the positioning gear is located at the top of the positioning seat, and a positioning slide groove is provided on the top of the positioning gear and parallel to the positioning seat. The middle part of the positioning gear is rotatably connected to a first positioning sleeve, and the bottom of the first positioning sleeve is connected to the top of the positioning seat through a bearing, and a group of positioning arc grooves are provided on the positioning gear, and a second positioning sleeve is provided inside each of the positioning arc grooves on both sides of the first positioning sleeve, and the second positioning sleeve slides on the positioning seat inside the positioning groove.

[0009] The cam is connected with the guide rail at the upper end thereof to the support frame, and the guide rail is connected with the support frame by the upper end face of the support rail, and the guide rail is connected with the support rail in a forward direction of the rotation of the steering column.

[0010] As a preferred solution of the present invention, the driving workpiece includes a driving motor, a driving shaft, a driving gear, a first bevel gear and a second bevel gear. The driving gear is sleeved through the outer circumferential wall below the driving shaft, and the driving gear is engaged on one side of the positioning gear.

[0011] As a preferred solution of the present invention, the first bevel gear is fixedly sleeved on the outer circumferential wall above the driving shaft, the second bevel gear is connected to the outer wall of the synchronous positioning screw close to the driving shaft, and the second bevel gear is meshed and connected with the first bevel gear.

[0012] As a preferred solution of the present invention, the output end of the driving motor is connected to the bottom of the driving shaft through a coupling, and the outer wall of the driving motor is fixed to the outer wall of the positioning seat.

[0013] As a preferred solution of the present invention, when the driving motor drives the driving shaft to rotate, the two second positioning sleeves are displaced synchronously with the first positioning slider and the second positioning slider.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In response to the problems raised in the background technology, the present application sets a crossbeam to position the workpiece and the rotary hole positioning workpiece to perform synchronous driving positioning by driving the workpiece, and simultaneously achieves unified positioning of multiple rotary hole positioning holes and multiple drill bits, with high work efficiency and low error rate;

[0016] No individual adjustments are required when drilling, which greatly reduces operation time and simplifies the process. There is no need to set up and adjust the equipment multiple times, which reduces the number of operation steps and complexity. Alignment is simple. Under the condition of unified positioning, all holes are ensured to be fully aligned, thus ensuring the installation quality of the gearbox crossbeam.

[0017] When the hole is rotated for positioning, the control device controls the driving motor to work, and the driving motor drives the driving shaft to rotate. When the driving shaft rotates, the driving gear on it is meshed and connected with the positioning gear, and the first bevel gear and the second bevel gear are meshed and connected. When the driving gear drives the positioning gear to rotate, the second positioning sleeve follows the structure inside the positioning arc groove and moves synchronously to both sides in the positioning slide groove. At this time, since the first bevel gear and the second bevel gear are meshed and connected, the second bevel gear is fixed to the end of the synchronous positioning screw rod. When the synchronous positioning screw rod rotates, the first positioning slide block and the second positioning slide block on it are synchronously displaced to ensure that the crossbeam processing drill bit and the second positioning sleeve are synchronously positioned;

[0018] This mold design can achieve unified positioning of multiple drill bits and rotary holes, significantly improving drilling efficiency, reducing errors, and solving the inefficiency and inaccuracy problems existing in traditional drilling methods. At the same time, this automatic and precise processing method also reduces labor intensity, improves production safety, and realizes efficient and precise processing of gearbox suspension beams, which is a major improvement to the existing production process.
