Description

Technical Field

[0001] This invention relates to the field of brake drum processing technology, and more specifically to an integrated processing equipment for automotive casting housings. Background Technology

[0002] Brake drums are the core rotating components of automotive drum braking systems, and their machining precision directly determines the vehicle's braking performance, ride comfort, and driving safety. Among these, the coaxiality of the friction inner circle with the mounting flange end face and the perpendicularity of the flange end face are the most critical indicators affecting brake vibration and vehicle drift.

[0003] Traditional brake drum machining employs a distributed processing method using multiple machines, typically requiring 3-5 machine tools to sequentially complete processes such as rough turning of the end face, drilling of the center hole, finish turning of the stop edge, finish turning of the inner circle, drilling of bolt holes, and grinding. This method has the following inherent drawbacks: 1. Large reference conversion error: Multiple clamping operations lead to the accumulation of reference conversion errors. The coaxiality error is usually between 0.05-0.1mm, which is difficult to meet the precision requirements of high-end models. 2. Severe clamping deformation: The external three-jaw chuck clamping the flange end face will cause elastic deformation of the workpiece, with a springback of 0.02-0.05mm after machining, which seriously affects the perpendicularity of the end face. In addition, the use of internal expansion sleeve type fixture occupies the internal space of the brake drum and interferes with the internal circle machining tool, making it impossible to complete all processes in one go.

[0004] 3. High production costs: The transfer and loading / unloading of workpieces between multiple machines takes up a lot of time, and the production cycle is usually more than 90 seconds per piece. A traditional production line requires 200-300 square meters of workshop space, and each machine needs to be equipped with an operator, resulting in high labor intensity.

[0005] 4. When machining brake drums, it is necessary to first find a rough datum and then find a fine datum. Switching requires manual intervention or an additional positioning mechanism, resulting in low automation and unstable accuracy. Furthermore, when machining with the workpiece opening facing upwards, chips are very easy to accumulate inside, scratching the machined friction inner circle surface, leading to unstable machining accuracy. Summary of the Invention

A push rod is provided at one end of the transmission gear shaft one, and a push spring is provided between the transmission gear shaft one and the inner wall of the clamping rocker arm. The gear on the transmission gear shaft one meshes with the gear on the fixed gear shaft. A swing gear is fixedly installed at the hinge of the clamping rocker arm, and the swing gear meshes with the gear on the transmission gear shaft two. The transmission gear shaft one and the transmission gear shaft two are connected by a toothed transmission belt. The inner wall of the groove is provided with a switching guide groove, and the inner wall of the switching guide groove is inclined. The top rod can slide along the switching guide groove. The interior of the suspension main shaft is provided with an installation groove, and a drive hydraulic cylinder is installed inside the installation groove. The output end of the drive hydraulic cylinder is hinged to a connecting rod, and the other end of the connecting rod is hinged to the main swing rod.

[0009] Furthermore, a connecting spring is provided between the clamping swing arm and the main swing arm. The connecting spring is used to drive the clamping swing arm to swing in the direction of the suspension main shaft. A reset magnetic block is provided on the inner wall of the inner positioning plate.

[0010] Furthermore, a guide bar is provided on the first transmission gear shaft, and a transmission pulley is sleeved between the two gears on the first transmission gear shaft.

[0011] Furthermore, a roller is provided at the top of the clamping lever.

[0012] Furthermore, the drilling assembly includes a drilling frame fixedly installed at the bottom of the frame, a vertical linear slide rail module 1 is installed on the drilling frame, a drive motor is installed on the slide of the vertical linear slide rail module 1, and a drill rod is installed at the bottom of the output end of the drive motor.

[0013] Furthermore, the internal cutting assembly includes a horizontal linear slide rail module 1 installed between the drilling frame and the positioning frame. Both ends of the slide of the horizontal linear slide rail module 1 are provided with cleaning nozzles.

[0016] Furthermore, a chip discharge port is provided at the inner bottom of the frame, and the chip discharge port is located directly below the inner cutting assembly.

[0017] The beneficial effects of this invention are as follows: 1. This invention uses the inner circular blank surface of the brake drum, which is the most important friction surface, as a rough reference, strictly adhering to the principle of prioritizing important surfaces. This ensures uniform machining allowance during subsequent finishing, improving coaxiality accuracy from the source. After rough machining, there is no need to re-clamp the workpiece. The clamping mode can be automatically switched by a single action of the driving hydraulic cylinder: from internal support type rough clamping to inverted conical center hole support. The inner positioning plate uses the newly machined fine reference surface (flange end face) as the positioning reference. With the three-point floating fine adjustment function, the fine reference surface is tightly fitted with the high-precision plane of the inner positioning plate, achieving a seamless switch from rough reference to fine reference. The reference switching process is fully automated and requires no manual intervention.

[0018] 2. In this invention, the brake drum opening faces downwards during suspended processing, and the chips fall directly under gravity, without accumulating inside the workpiece, thus completely avoiding the problem of chips scratching the processed surface.

[0019] 3. This invention integrates a suspended spindle, drilling assembly, internal cutting assembly, end face cutting assembly, and upper positioning assembly on a single frame, enabling continuous completion of multiple processes such as end face finishing, drilling, friction internal turning, and external turning. It avoids the need for workpiece transfer, re-clamping, and alignment between multiple machines, significantly reducing auxiliary time, and is particularly suitable for the mass production of automotive casting bodies.

[0023] Example 1, as Figures 1-10As shown, an integrated processing equipment for automobile casting housings includes a frame 1, a suspension spindle 2 is installed on the inner top of the frame 1, and three sets of grooves 22 are circumferentially opened on the outer side of the suspension spindle 2. Three sets of clamping and positioning components 3 are arranged in the grooves 22. The clamping and positioning components 3 include a main swing rod 31 hinged in the groove 22, and a swinging clamping swing rod 32 is provided on the top of the main swing rod 31. The inner bottom of the frame 1 is equipped with a drilling assembly 4, an upper positioning assembly 5 and an end face cutting assembly 7. The drilling assembly 4 and the upper positioning assembly 5 are located on the right and left sides of the suspended spindle 2, respectively. The end face cutting assembly 7 is located on the back of the suspended spindle 2. An inner cutting assembly 6 for turning the inner wall is provided between the drilling assembly 4 and the upper positioning assembly 5. The upper positioning component 5 includes a positioning frame 51 installed at the bottom of the frame 1. A vertical linear slide rail module 2 52 is provided on the positioning frame 51. An outer frame plate 53 is provided on the slide of the vertical linear slide rail module 2 52. An inner positioning disk 54 is rotatably installed inside the outer frame plate 53. A guide hole is provided on the inner positioning disk 54.

[0024] The drilling assembly 4 includes a drilling frame 41 fixedly installed at the bottom of the frame 1. A vertical linear slide rail module 42 is installed on the drilling frame 41. A drive motor 43 is installed on the slide of the vertical linear slide rail module 42. A drill rod 44 is installed at the bottom of the output end of the drive motor 43.

[0025] The internal cutting assembly 6 includes a horizontal linear slide rail module 61 installed between the drilling frame 41 and the positioning frame 51. Both ends of the slide of the horizontal linear slide rail module 61 are provided with cleaning nozzles. A lifting hydraulic cylinder 62 is installed on the slide of the horizontal linear slide rail module 61. An internal cutting head 63 is installed on the telescopic end of the lifting hydraulic cylinder 62.

[0026] The end face cutting assembly 7 includes a cutting bracket 71 installed at the bottom of the frame 1. A vertical linear slide rail module 3 72 is installed on the cutting bracket 71. A horizontal support plate 73 is installed on the slide of the vertical linear slide rail module 3 72. A horizontal linear slide rail module 2 74 is installed on the top of the horizontal support plate 73.

The end face cutting tool 75 is driven by a motor and is a double-ended tool, with one end for roughing and the other end for finishing.

[0027] The drilling frame 41, positioning frame 51, and cutting support 71 are all reinforced with reinforcing ribs. A chip discharge port 11 is provided at the inner bottom of the frame 1, and the chip discharge port 11 is located directly below the inner cutting assembly 6.

[0028] Brake drum casting shell machining principles: (1) Priority principle for important surfaces: The first machining of the brake drum can only use the cast blank surface as the positioning datum (rough datum). Its selection must strictly follow the following principles: select the most important surface that needs to be finished later as the rough datum to ensure that its machining allowance is uniform. For the brake drum, the friction inner circle blank surface is the most important surface and must be used as the first rough datum.

[0029] The principle of non-reuse: The rough datum can only be used once, because the accuracy of the blank surface is low, and repeated use will produce a large datum conversion error.

[0030] Therefore, for the integrated molding of brake drum castings, accurately switching the reference surface is particularly important.

[0031] Processing steps: (1) Establishing a rough datum: Before loading, the main swing rod 31 and the clamping swing rod 32 are both gathered in the groove 22. When loading, the material is loaded from the front of the suspension spindle 2 without obstruction. The opening of the brake drum casting shell is facing down. Then, it is placed on the suspension spindle 2 from below until it exceeds the groove 22. Then, the main swing rod 31 is controlled to swing outward, and the clamping swing rod 32 swings relative to the main swing rod 31, always maintaining a vertical state. Then, the brake drum is released so that it falls on the clamping swing rod 32. As the main swing rod 31 continues to unfold, the clamping swing rod 32 is in a vertical state and closely adheres to the B surface (friction inner circle blank surface) of the brake drum casting shell. The brake drum casting shell is clamped by the suspension inner support clamping method to complete the establishment of the rough datum.

[0032] Machining of the precision reference surface (A surface): The vertical linear slide rail module 3 72 is controlled to operate, and the cutting depth of the end face cutting tool 75 is adjusted by the vertical linear slide rail module 3 72. The horizontal linear slide rail module 2 74 controls the feed of the end face cutting tool 75. The suspension spindle 2 drives the brake drum casting housing to rotate at high speed through the clamping swing arm 32. The reference surface is first rough machined to provide a reference for drilling. Then, the vertical linear slide rail module 1 42 is controlled to descend so that the drill rod 44 passes through the guide hole of the inner positioning plate 54 to drill the brake drum casting housing. The brake drum casting housing is rotated relative to the drill rod 44 by the suspension spindle 2 to adjust the drilling position and perform multiple drilling operations. After drilling is completed, the motor drives the end face cutting tool 75 to rotate. The precision machined end rotates to face downwards on the brake drum casting housing and performs precision machining again to complete the machining of the precision reference surface (A surface). A cleaning nozzle can be installed in the equipment, angled towards the A surface, to blow away debris or spray cutting fluid while cutting and drilling.

[0033] Precise positioning: Control the main swing arm 31 to swing inward and retract, while simultaneously controlling the clamping swing arm 32 to swing inward. The main swing arm 31 swings until it does not interfere with the path of the inner cutting head 63, and the maximum width between the three sets of main swing arms 31 is greater than the diameter of the central through hole of the brake drum casting shell. The top of the clamping swing arm 32 abuts against the inner wall of the groove 22, and the three sets of clamping swing arms 32 form an inverted cone shape. The clamping swing arm 32, the main swing arm 31, and the groove 22 form a stable triangular structure. At this time, control the vertical linear slide rail module 2 52 to run. The vertical linear slide rail module 2 52 drives the outer frame plate 53 to descend, and the outer frame plate 53 drives the inner positioning plate. As the inner positioning plate 54 descends, it should be noted that the bottom surface of the inner positioning plate 54 is lower than the bottom surface of the outer frame plate 53. Therefore, the bottom surface of the inner positioning plate 54 is in contact with the precision reference surface (A surface). The high-precision plane pre-set on the bottom surface of the inner positioning plate 54 achieves the determination of the precision reference surface and realizes accurate positioning by stably contacting the precision reference surface (A surface). Furthermore, the inner wall of the central through hole of the brake drum casting housing is supported by the inverted conical clamping swing rod 32. Then, the swing angle of the main swing rod 31 is controlled separately to perform three-point floating fine adjustment of the brake drum casting housing, so that the precision reference surface (A surface) is closely attached to the bottom surface of the inner positioning plate 54, realizing automatic switching of the precision reference.

[0034] B-side machining: The suspended spindle 2 drives the brake drum casting housing to rotate at high speed, the horizontal linear slide rail module 61 controls the cutting depth, and the lifting hydraulic cylinder 62 controls the cutting feed to realize B-side machining.

[0035] C-surface machining: The suspended spindle 2 drives the brake drum casting housing to rotate at high speed, and the end face cutting component 7 is used to machine the C-surface. The horizontal linear slide rail module 2 74 controls the cutting depth, and the vertical linear slide rail module 3 72 controls the cutting feed.

[0036] With the integrated processing equipment of this invention, the complete processing of the brake drum casting shell can be achieved in the same equipment, which occupies little space, has high processing efficiency, and automatically adjusts the rough and fine references, resulting in high processing accuracy. At the same time, the suspension processing of the friction inner circle surface of the brake drum casting shell can effectively prevent the accumulation of debris inside the brake drum casting shell, and the processing accuracy of the friction inner circle surface is high.

[0037] Example 2, based on the above example, further includes: a hinge shaft fixedly installed inside the groove 22; the clamping rocker arm 32 is hinged to the hinge shaft; a fixed gear shaft 34 is fixedly installed on the hinge shaft; a transmission gear shaft 1 35 and a transmission gear shaft 2 36 are rotatably installed inside the clamping rocker arm 32; two gears are provided on each of the transmission gear shaft 1 35, the transmission gear shaft 2 36, and the fixed gear shaft 34; a push rod is provided at one end of the transmission gear shaft 1 35; a top spring 351 is provided between the transmission gear shaft 1 35 and the inner wall of the clamping rocker arm 32; the gear on the transmission gear shaft 1 35 meshes with the gear on the fixed gear shaft 34; a swing gear 37 is fixedly installed at the hinge of the clamping rocker arm 32; the swing gear 37 meshes with the gear on the transmission gear shaft 2 36; and the transmission gear shaft 1 35 and the transmission gear shaft 2 36 are connected by a toothed transmission belt. The inner wall of the groove 22 is provided with a switching guide groove 23. The inner wall of the switching guide groove 23 is inclined, and the top rod can slide along the switching guide groove 23. The interior of the suspension main shaft 2 is provided with an installation groove 21. The installation groove 21 is installed with a drive hydraulic cylinder 38. The output end of the drive hydraulic cylinder 38 is hinged to a connecting rod 39, and the other end of the connecting rod 39 is hinged to the main swing rod 31.

[0038] A connecting spring bar 33 is provided between the clamping swing arm 32 and the main swing arm 31. The connecting spring bar 33 is used to drive the clamping swing arm 32 to swing in the direction of the suspension main shaft 2. A reset magnetic block is provided on the inner wall of the inner positioning disk 54.

[0039] A guide bar 352 is provided on the first transmission gear shaft 35. A transmission pulley 353 is sleeved between two gears on the first transmission gear shaft 35. A guide groove is opened on the inner wall of the transmission pulley 353. The guide bar 352 is slidably connected in the guide groove. The transmission pulley 353 is connected to the second transmission gear shaft 36 through a toothed transmission belt. A roller is provided at the top of the clamping rocker arm 32.

[0040] This embodiment provides a swing control method for the main swing arm 31 and the clamping swing arm 32. Using conventional drive will result in a bulky structure of the clamping and positioning assembly 3, which may easily affect the subsequent machining trajectory of the inner friction surface (B surface).

[0041] Therefore, through this embodiment, during coarse reference clamping, the control hydraulic cylinder 38 is operated, and the drive hydraulic cylinder 38 drives the main swing rod 31 to swing outward through the connecting rod 39. The main swing rod 31 drives the clamping swing rod 32 to swing outward together. The main swing rod 31 drives the transmission gear shaft 1 35 to swing around the fixed gear shaft 34. The fixed gear shaft 34 causes the transmission gear shaft 1 35 to rotate. The transmission gear shaft 1 35 drives the transmission gear shaft 2 36 to rotate through the transmission pulley 353 and the toothed transmission belt. The transmission gear shaft 2 36 drives the clamping swing rod 32 to swing in the opposite direction to the main swing rod 31 through the swing gear 37. The clamping swing rod 32 always remains in a horizontal state, so that the clamping swing rod 32 can be vertically pressed against the friction inner circular surface (surface B), thus realizing coarse reference clamping.

[0042] When precise clamping is required, the drive hydraulic cylinder 38 is operated. The drive hydraulic cylinder 38 drives the main swing rod 31 to swing inward via the connecting rod 39. The main swing rod 31 drives the clamping swing rod 32 to swing inward together. When the transmission gear shaft 35 swings to the position of the switching guide groove 23, under the action of the inclined surface of the switching guide groove 23 and the push rod, the transmission gear shaft 35 slides relative to the main swing rod 31. The transmission gear shaft 35 compresses the top spring 351, and the gear on the transmission gear shaft 35 is misaligned with the gear on the fixed gear shaft 34. The transmission pulley 353 is in the tooth profile transmission Under the limiting action of the moving belt, it remains stationary and slides relative to the transmission gear shaft 35. At this time, the clamping swing rod 32 is not constrained and swings inward relative to the main swing rod 31 under the action of the connecting spring strip 33. The clamping swing rod 32 is pressed against the inner wall of the groove 22 under the elastic force of the connecting spring strip 33. The three sets of clamping swing rods 32 form an inverted cone shape, and the clamping swing rod 32, the main swing rod 31 and the groove 22 form a stable triangular structure. The inner wall of the central through hole of the brake drum casting shell is pressed against the outside of the clamping swing rod 32, and the clamping swing rod 32 provides a stable clamping support force.

[0043] In the actual design process, the inner diameter of the inner positioning plate 54 is larger than the inner diameter of the central through hole of the brake drum casting housing. Therefore, the part of the clamping rocker arm 32 that exceeds the inner positioning plate 54 can also pass through the inner positioning plate 54 stably without affecting the fit between the inner positioning plate 54 and surface A. This design also achieves another effect: because the final transmission gear shaft 35 is misaligned with the fixed gear shaft 34, it cannot be guaranteed that the clamping rocker arm 32 will always remain vertical during the next use. Therefore, after processing, the inner positioning plate 54 is lowered by the vertical linear slide rail module 52, so that the clamping rocker arm 32 can contact the inner wall of the inner positioning plate 54. As the main rocker arm 31 swings outward, when the transmission gear shaft 35 just disengages from the switching guide groove 23, the reset magnetic block attracts the clamping rocker arm 32 into a vertical position under the action of magnetic force. In the state where the clamping lever 32 is vertically attached to the reset magnetic block, the clamping lever 32 drives the transmission gear shaft 35 to rotate through the swing gear 37, the transmission gear shaft 2 36 and the transmission pulley 353, so that the teeth on the transmission gear shaft 35 tend to mesh with the teeth on the fixed gear shaft 34. Therefore, under the action of the top spring 351, the transmission gear shaft 35 can be smoothly reset and mesh with the fixed gear shaft 34 again, realizing the self-resetting effect of the device. No manual adjustment is required. It can be achieved by utilizing the effect of the inner positioning plate 54 itself, with a high degree of automation.

[0044] This implementation setup can significantly reduce the overall volume of the clamping and positioning assembly 3, giving the internal cutting head 63 more machining space.
