Description

Technical Field

[0001] The invention relates to the technical field of front axle auxiliary processing, and in particular to a front axle housing auxiliary processing tool. Background Art

[0002] The front axle is a kind of automobile spare part. Its function is to transmit the various directional forces between the frame and the front wheels and the bending moment and torque generated by them. It is mainly composed of four parts: front axle, steering knuckle, kingpin and wheel hub. Among them, the front axle, as the main part of the front axle, has higher requirements on toughness and hardness.

[0003] There is a thickened part at each end of the front axle in the shape of a fist (such as Fig. 9 As shown), its function is to improve the torsional strength. Through holes are opened at both ends of the front axle, and the kingpin is inserted into the hole. Because the inner wall of the through hole cooperates with the kingpin, in order to prevent the gap between the two from being too large, causing serious wear during relative movement, the through hole processing progress is required to be high. Generally, fine processing is required after rough processing to meet its matching strength. The axis of the through hole opened at both ends of the front axle has a certain deviation angle relative to the horizontal line of the front axle, in order to facilitate the coordination of the angle between the kingpin inclination angle and the front wheel camber angle for front wheel positioning. However, a specific drilling machine is required to process the through hole with an inclined angle. The head mechanism is deflected through design programming to process the hole position. On the one hand, the cost of designing special equipment is relatively high and the use is relatively complicated. On the other hand, the through hole position of the front axle is relatively deep.

The upper side of the driving transmission unit 32 is movably connected to the limited blocking unit 34, and the end of the limited blocking unit 34 away from the inner wall of the fixed shell 31 is installed with a connecting and conveying unit 35, and the upper end of the connecting and conveying unit 35 is fixedly connected to the upper end of the inner wall of the fixed shell 31, and supporting and abutting units 36 are installed on the left and right sides of the connecting and conveying unit 35, and the upper end of the supporting and abutting unit 36 ​​abuts against the lower end of the balance board 5.

[0031] See also Figure 5The driving transmission unit 32 includes a grip turntable 321, which is located outside the fixed shell 31. A sliding column 322 that penetrates into the fixed shell 31 is fixedly installed on one side of the grip turntable 321 close to the fixed shell 31, and a snap ring is fixedly installed on the surface of the sliding column 322. A load sleeve 323 is slidably installed on the end of the sliding column 322 away from the grip turntable 321. A limiting sliding groove 324 is provided inside the load sleeve 323 for the sliding of the sliding column 322. A driving gear 325 is fixedly installed on the end of the load sleeve 323 away from the sliding column 322. A two-way gear 326 is meshed and installed on the left and right sides of the driving gear 325. The two-way gear 326 consists of two transfer bevel gears, and a rotating rod is fixedly installed between the two transfer bevel gears. The two transfer bevel gears close to the drive gear 325 are both meshed and connected with the drive gear 325, and the transfer bevel gear away from the drive gear 325 is connected to the vertical height adjustment unit 33.

[0032] See also Figure 2-5 The vertical height adjustment unit 33 includes a force-bearing gear 331, which is meshed with the transmission bevel gear of the two-way gear 326 away from the driving gear 325. A load-bearing threaded sleeve 332 is fixedly installed on the upper end of the force-bearing gear 331, and a limiting cross frame 333 is rotatably installed on the surface of the load-bearing threaded sleeve 332. One end of the limiting cross frame 333 away from the force-bearing gear 331 is fixedly connected to the inner wall of the fixed shell 31, and a threaded rod 334 is threadedly connected to the inside of the force-bearing gear 331.

The guide plates are located inside the limiting narrow groove 312, and the upper end of the adjusting rod 335 is spherical.

[0033] The front axle of the front axle is placed on the upper end of the rotating unit 6 and fixed by the clamping cylinder 7. When adjusting the left height of the front axle and the right height of the front axle, the gripping turntable 321 is manually rotated, and the load sleeve 323 and the driving gear 325 are driven to rotate together through the sliding column 322, so that the left bidirectional gear 326 is rotated and drives the left force-bearing gear 331 to rotate around its own axis, so that the left threaded rod 334 is pushed upward by the force-bearing gear 331 on the left, thereby driving the left adjustment rod 335 to produce an adjustment on the balance plate 5. The thrust is generated, so that the left end of the balance board 5 moves upward around the supporting shaft column 4. Since the two-way gear 326 at the left end of the driving gear 325 and the two-way gear 326 at the right end of the driving gear 325 rotate in opposite directions as the driving gear 325 rotates, the force-bearing gear 331, the threaded rod 334 and the adjusting rod 335 on the right side generate a downward pulling force on the right end of the balance board 5, so that the right end of the balance board 5 moves downward accordingly around the supporting shaft column 4. By controlling the rotation angle of the grip dial 321, the purpose of controlling the deflection angle of the front axle of the front axle is achieved.

[0034] See also Figure 5 The limiting blocking unit 34 includes a bending rod 341, a limiting sleeve 342 is fixedly installed at the lower end of the bending rod 341, the limiting sleeve 342 is rotatably installed on the surface of the limiting sleeve 342, a snap-fit ​​groove is opened inside the limiting sleeve 342, the snap-fit ​​groove cooperates with the snap-fit ​​ring, the front end of the bending rod 341 is slidably connected with a balancing rod 343, the end of the balancing rod 343 away from the bending rod 341 is fixedly installed on the inner wall of the fixed shell 31, and a blocking plate 344 is fixedly installed at the rear end of the balancing rod 343, and two sets of limiting members 345 are symmetrically fixedly installed on the surface of the bending rod 341 from top to bottom, and the limiting members 345 are composed of two trapezoidal blocks.

[0035] See also Figure 5 The interconnecting conveying unit 35 includes a protective cover 354, the upper end of the protective cover 354 is fixedly connected to the upper end of the inner wall of the fixed shell 31, and the inner wall of the protective cover 354 is symmetrically fixedly installed with elastic clamping rods 351, and a spring is installed inside the elastic clamping rod 351. In the initial state, one end of the elastic clamping rod 351 close to the bending rod 341 is clamped with the limit member 345, and a sealing chamber 352 is fixedly installed inside the protective cover 354, and a connecting hole 353 is opened inside the sealing chamber 352.

[0036] See also Figure 2 and Figure 6 and Figure 7 The supporting and abutting unit 36 ​​includes a hydraulic pipe 361, one end of which is fixedly connected to the surface of the protective cover 354, and the other end of which is fixedly connected to the inside of the fixed housing 31. A sealing plate 362 is slidably installed inside the hydraulic pipe 361, and a guide column 363 is fixedly installed on the upper end of the sealing plate 362. An abutting rocking plate 364 is rotatably installed on the upper end of the guide column 363, and the upper end of the abutting rocking plate 364 abuts against the lower end of the balance plate 5. Please refer to Figure 4 A displacement slide 51 is provided on the left and right sides of the lower end of the balance plate 5, a connecting block 52 is slidably installed inside the displacement slide 51, a spherical groove is provided at the lower end of the connecting block 52, and the upper end of the adjusting rod 335 is located inside the spherical groove.

[0037] When the angle of the balance plate 5 is adjusted, the abutting rocking plate 364 abutting against the bottom of the balance plate 5 moves together with the movement of the balance plate 5, so that the abutting rocking plate 364 on the right side is driven by the thrust of the balance plate 5 to drive the guide column 363 and the sealing plate 362 to move downward, thereby squeezing the liquid inside the hydraulic pipe 361, and then the squeezed liquid enters the hydraulic pipe 361 on the left side through the connecting conveying unit 35, pushing the sealing plate 362, the guide column 363 and the abutting rocking plate 364 on the left side to move upward, so that the abutting rocking plate 364 on the left side always keeps in contact with the bottom of the balance plate 5, and at this time, the gripping turntable 321 is pushed, so that the gripping turntable 321 drives the sliding column 322 to move to the right rear side, so that the end of the sliding column 322 away from the gripping turntable 321 is inserted deep into the load sleeve 323, and at the same time, as the sliding column The movement of 322 causes the load-bearing threaded sleeve 332 to drive the bending rod 341 to move in the direction away from the balancing rod 343, so that the bending rod 341 drives the blocking plate 344 to move in the direction of the connecting hole 353. During the movement of the bending rod 341, the limiting piece 345 close to the side of the connecting hole 353 is separated from the limiting piece of the elastic clamping rod 351. At this time, the movement of the bending rod 341 is more convenient. When the blocking plate 344 moves to a position that completely covers the connecting hole 353, the limiting piece 345 close to the side of the balancing rod 343 is just limited by the elastic clamping rod 351, that is, the bending rod 341 is limited to prevent the bending rod 341 from being displaced after driving the blocking plate 344 to block the connecting hole 353, resulting in a loophole in the blocking of the connecting hole 353, resulting in the hydraulic pipes 361 on the left and right sides being connected.

[0038] See also Figure 8 The rotating unit 6 includes a fixed truncated table 61, the lower end of the fixed truncated table 61 is fixedly connected to the upper end of the balance plate 5, a placement groove 62 is provided inside the fixed truncated table 61, a supporting ball column 63 is fixedly connected to the upper end of the inner wall of the placement groove 62, a rotating disk 64 is slidably connected to the upper end of the supporting ball column 63, the upper end of the rotating disk 64 is fixedly connected to the lower end of the clamping cylinder 7, plug-in slots 65 are provided on the left and right sides of the rotating disk 64, and an annular groove matching the supporting ball column 63 is provided under the rotating disk 64, plug holes 66 are provided on the left and right sides of the fixed truncated table 61, and a positioning rod 67 is slidably installed on the inner wall of the plug hole 66. When the rotating disk 64 and the fixed truncated table 61 are relatively stationary, the positioning rod 67 is inserted into the plug-in slot 65.

[0039] After the balancing plate 5 drives the front axle of the front axle to deflect and stabilize, that is, after the axis line to be drilled is parallel to the drill bit, the end to be processed of the front axle of the front axle is drilled. After the drilling is completed, the positioning rods 67 on both sides of the rotating disk 64 are pulled outward, so that the end of the positioning rods 67 close to the rotating disk 64 is separated from the rotating disk 64. At this time, the rotating disk 64 is in a rotatable state. By rotating the rotating disk 64, the front axle of the front axle at the upper end of the rotating disk 64 can be driven to rotate together. When the rotating disk 64 rotates to 180 degrees, the unprocessed end of the front axle of the front axle is rotated to the lower end of the drill bit to wait for processing. After the rotation is completed, the positioning rod 67 is pushed so that the positioning rod 67 is inserted into the rotating disk 64 to achieve the purpose of fixing the rotating disk 64. Finally, the inclination angle of the balancing plate 5 and the rotating unit 6 is adjusted by the inclination adjustment unit 3, thereby adjusting the inclination angle of the front axle of the front axle, which is convenient for processing the hole position.
