Description

Technical Field

[0001] This invention relates to the field of metal processing equipment technology, and more specifically to a left and right shock-absorbing tower milling clamping device. Background Technology

[0002] The shock absorber tower is an important component of a vehicle's body structure. During vehicle operation, the shock absorber tower is used to transfer the forces acting on the suspension to the vehicle body.

[0003] Existing shock absorber towers are generally manufactured by high-pressure casting of aluminum alloy, followed by machining operations such as drilling. Surface processing of the side plates is unnecessary. However, high-pressure casting is costly. To reduce costs while maintaining strength, low-pressure casting is used instead. However, low-pressure casting has lower strength than high-pressure casting, and the surface of the outer wall of the side plates is inferior, lacking smoothness. Therefore, milling is required. However, because the side plates are thin-walled, they cannot be clamped and fixed, and milling easily deforms the plates, resulting in very poor machining accuracy and making it unsuitable for processing. Furthermore, existing shock absorber towers lack positioning detection devices during clamping, making it impossible to confirm proper installation. Since the positioning point is internal, the inside faces downwards during clamping, making manual inspection impossible. This leads to machining before proper installation, resulting in scrapped products, poor performance, and high manual labor costs.

[0004] Meanwhile, existing shock absorber towers generally include a left shock absorber tower and a right shock absorber tower, but general clamps can only clamp a single shock absorber tower or shock absorber towers in the same direction, and cannot clamp a pair of shock absorber towers at once, resulting in poor clamping effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a left and right shock absorber tower machining clamping device. It can clamp a pair of shock absorber towers at a time, thus enabling the machining of a pair of shock absorber towers simultaneously. Furthermore, it features a vertically thickened section and a side-clamping cylinder formed on the outer wall of the outer side plate of the shock absorber tower, which can clamp the side plate, facilitating milling of the outer wall surface and ensuring machining accuracy. Additionally, its upper limit protrusion and airtightness sensing column can detect the clamping position of the shock absorber tower, ensuring it is properly clamped, eliminating the need for manual inspection and greatly improving the automatic machining effect and efficiency.

[0006] The solution of the present invention to the aforementioned technical problem is:

A lower connecting seat is fixed to the lower part of the outer side of the middle support block of the vertically thickened part. A side clamping cylinder is fixed on the outer side wall of the lower connecting seat. A corresponding transverse hinge shaft is fixed to the end of the push rod of the side clamping cylinder.

The upper extension 305 corresponds to the end of the corresponding rear support cylinder 301 above.

[0043] A sensing connection seat 307 is fixed on the middle support block 30 on one side of the clamping cylinder 302. A lower support column 1 is fixed on the lower part of the sensing connection seat 307. An upper support column 2 is fixed on the rear wall of the middle support block 30 on the upper part of the sensing connection seat 307.

The limiting rod is inserted into the arc-shaped through hole 3081, and the two ends of the limiting rod are fixed to the two middle extension connecting parts.

[0046] Furthermore, the two rear support blocks 20 are abutted on one side and fixedly connected by multiple connecting blocks.

The bottom surface of the front end of the upper clamping block 23 is fixed with a wear-resistant and anti-slip clamping block, which corresponds to the outer wall surface of the shock absorber tower 100 to be clamped.

[0048] Furthermore, each of the rear support blocks 20 on one side of the upper pressing cylinder 22 is fixed with a corresponding induction connection seat 307. The structure of the induction connection seat 307 is basically the same as that of the induction connection seat 307 at the pressing cylinder 302, and will not be described in detail.

[0049] Furthermore, an internal support cylinder 3 is fixed on the side wall of the middle support block 30, which is opposite to the wear-resistant and anti-slip pressing block at the front end of the upper clamping block 23 of the upper clamping cylinder 22 at the outer end and the inner end of the rear support block 20. The upper end of the internal support cylinder 3 corresponds to the wear-resistant and anti-slip pressing block at the front end of the upper clamping block 23 of the corresponding upper clamping cylinder 22.

[0050] Furthermore, a rear connecting seat is fixed on the top surface of the through groove 21 of the rear support block 20 behind the rear support cylinder 301 fixed at the upper part of the rear wall of the middle support block 30. A rear push cylinder 24 is fixed on the rear connecting seat. A guide plate is fixed at the front end of the push rod of the rear push cylinder 24.

[0053] A central threaded hole is formed in the middle of the top surface of the upper sensing connection block 41. The lower part of the upper limit protrusion 42 is threaded onto the inner wall of the corresponding central insertion hole. The top of the upper limit protrusion 42 extends out of the top surface of the upper sensing connection block 41. A downwardly extending side guide hole is formed on the top surface of the edge of the upper sensing connection block 41. The airtight sensing post 43 is inserted into the side guide hole. A vertically penetrating detection hole is formed in the middle of the airtight sensing post 43. The outer side wall of the airtight sensing post 43 is in close contact with the inner side wall of the side guide hole. The radially extending edge formed on the lower outer side wall of the airtight sensing post 43 is inserted into the annular groove formed on the bottom inner side wall of the side guide hole. The detection hole communicates with the annular groove. A sealing ring is pressed against the top surface of the radially extending edge. The top surface of the sealing ring is pressed against the annular groove. On the top surface of the groove, a sealing ring is fitted onto the airtight sensing column 43. A compression spring 431 is inserted into the bottom of the airtight sensing column 43. The compression spring 431 is located in the annular groove. The bottom end of the compression spring 431 presses against the top surface of the sealing gasket, and the top end of the compression spring 431 presses against the bottom surface of the radially extending edge. A radially extending side through hole is formed on the lower side wall of the upper sensing connecting block 41. The side through hole communicates with the annular groove. The side through hole is connected to the pipeline of the outlet end of the external high-pressure air source through a connecting pipe. A pressure sensor is fixed on the side wall of the pipeline at the outlet end of the high-pressure air source. The sensing end of the pressure sensor extends into the pipeline. It senses the pressure in the pipeline through the pressure sensor. The pressure sensor and other components are conventional structures and will not be described in detail here.

[0054] Furthermore, the top of the upper limit protrusion 42 is inserted into the concave hole formed in the middle of the bottom surface of the protrusion 102 at the corresponding position on the bottom surface of the top plate of the shock absorber tower 100 to be clamped, and the bottom surface of the protrusion 102 presses against the top surface of the upper sensing connection block 41 and covers the top of the detection through hole of the airtight sensing column 43.

[0055] Furthermore, the lower middle part of the outer side wall of the shock absorber tower 100 to be clamped has a vertically thickened part 103 formed therein. The lower part of the outer side of the middle support block 30 at the vertically thickened part 103 is fixed with a lower connecting seat 50. A side clamping cylinder 51 is fixed on the outer side wall of the lower connecting seat 50. The end of the push rod of the side clamping cylinder 51 is fixed with a corresponding transverse hinge shaft 303. The transverse hinge shaft 303 is movably connected to the rear part of the corresponding side clamping block 52 located outside the side clamping cylinder 51. A wear-resistant and anti-slip clamping block is fixed on the inner end face of the upper end of the side clamping block 52, which presses against the outer side wall of the vertically thickened part 103.

[0056] Furthermore, a corresponding sensing connection seat 307 is also fixed on the outer wall of the lower connecting seat 50 on one side of the side clamping cylinder 51. The structure of the sensing connection seat 307 is basically the same as that of the sensing connection seat 307 at the clamping cylinder 302, and will not be described in detail.

[0057] Furthermore, a bottom rotating plate is installed in the center of the bottom surface of the main fixing base plate 10. The bottom rotating plate is a circular plate with one side wall being vertical. A downward-extending central through hole is formed in the center of the top surface of the bottom rotating plate. A lower annular groove is formed in the inner side wall of the lower end of the central through hole. The bottom surface of the lower annular groove extends out of the bottom surface of the bottom rotating plate. Multiple radially extending protruding positioning strips are formed on the edge of the top surface of the bottom rotating plate, evenly distributed around the central axis of the bottom rotating plate. A downward-extending connecting screw post is fixed in the center of the bottom surface of the main fixing base plate 10. The protruding positioning strips are inserted into the corresponding elongated grooves formed in the bottom surface of the main fixing base plate 10. The top surface of the protruding positioning strips presses against the top surface of the corresponding elongated grooves. The bottom end of the connecting screw post extends out of the bottom surface of the lower annular groove and is screwed with a locking nut. The top surface of the nut presses against the top surface of the lower annular groove. Multiple locking side slots are formed on the outer wall of the locking nut. A guide block is fixed on the top surface of the lower annular groove on one side of the bottom of the connecting screw. A radially extending through groove is formed in the middle of the guide block. The locking plate is inserted into the radially extending through groove. The outer wall of the locking plate matches the inner wall of the radially extending through groove. The inner end of the locking plate extends out of the inner end of the radially extending through groove and is inserted into the corresponding locking side slot. The outer end of the locking plate extends out of the outer end of the radially extending through groove and is fixed with a toggle part. A connecting block is fixed on the top surface of the lower annular groove at the outer end of the toggle part. One end of the return spring is fixed on the outer end of the toggle part and the other end is fixed on the connecting block. An iron block is fixed on the outer end of the toggle part. A permanent magnet block is fixed at the corresponding position of the connecting block, corresponding to the iron block.

[0058] This structure allows for adjustments to the relative position of the bottom rotating plate and the main fixed base plate 10. Specifically, by changing the position of the vertical surface of the bottom rotating plate, the actuating part can be pulled outwards, causing the permanent magnet block to adhere and fix to the corresponding iron block. At this time, the inner end of the locking plate moves out of the locking side slot. Then, the locking nut is rotated to move downwards, and the bottom rotating plate is moved downwards, causing the protruding positioning strip to move out of the corresponding elongated groove. The bottom rotating plate is then rotated to change the position of its vertical surface to the desired position (in this embodiment, changing one position is 45°). The bottom rotating plate is then lifted, the protruding positioning strip is inserted into the corresponding elongated groove, the locking nut is tightened, and the actuating part is moved to separate the permanent magnet block from the iron block. The inner end of the locking plate extends out of the inner end of the radially extending through groove and inserts into the corresponding locking side slot, thus positioning the locking nut and preventing its rotation.

[0059] In this embodiment, the two shock absorbers 100 are first installed at the left and right installation positions. The front end of the front support cylinder 32 presses against the inner wall of the front vertical plate of the corresponding shock absorber 100. The top surface of the middle vertical support block 33 presses against the inner wall of the inclined wall plate at the upper part of the front of the corresponding shock absorber 100. The top surface of the outer support plate 34 presses against or is in close contact with the inner wall of the inclined wall plate on the outer side of the corresponding shock absorber 100. The rear wall of the rear vertical baffle 35 is in close contact with the inner side wall of the rear wall plate of the shock absorber 100 to be processed. The ends of the first support cylinder 37, the second support cylinder 38, and the outer support cylinder 39 press against the corresponding inner side wall of the corresponding shock absorber 100 to achieve support.

[0060] Meanwhile, the top of the front vertical positioning column 11 is inserted into the front recess 101 formed on the bottom surface of the top plate at the front end of the shock absorber tower 100 to be clamped, thus achieving front positioning. The top of the upper limit protrusion column 42 is inserted into the recess formed in the middle of the bottom surface of the protrusion 102 at the corresponding position on the bottom surface of the top plate of the shock absorber tower 100 to be clamped. The bottom surface of the protrusion 102 presses against the top surface of the upper sensing connection block 41 and covers the top of the detection through hole of the airtight sensing column 43. At this time, the pressure value of the pressure sensor fixed on the side wall of the pipeline at the outlet of the high pressure air source will continue to rise. When it reaches the set value, it indicates that the shock absorber tower 100 is placed correctly.

[0061] This structure ensures that the shock absorber tower 100 is securely clamped and fixed.

[0062] At this time, the push rod of the clamping cylinder 302 is pushed, and the push rods of all the upper clamping cylinders 22 are pushed, so that the wear-resistant and anti-slip clamping blocks fixed on the front end of the upper extension 305 of the upper end of the clamping block 304 and the bottom surface of the front end of the upper clamping block 23 press against the outer wall surface of the corresponding shock absorber tower 100, thereby achieving clamping and fixing. At this time, the corresponding end of the corresponding sensing arm 309 is sensed by the top sensing part of the lower support column 1, indicating that it has moved into place and is clamped in place.

[0063] At the same time, the push rod of the side clamping cylinder 51 is also pushed, so that the wear-resistant and anti-slip clamping block fixed on the inner end face of the upper end of the side clamping block 52 presses against the outer wall of the vertical thickened part 103, thereby fixing the corresponding position of its side plate. At this time, the shock absorber tower 100 is firmly clamped.

[0064] Among them, since the lower middle part of the outer side wall of the shock absorber tower 100 to be clamped has a vertically thickened part 103, it increases the strength of the corresponding side plate of the shock absorber tower 100, making it firmly fixed and not easily deformed during the processing, thus ensuring the accuracy of the milling process of its outer wall surface.

[0065] It can be processed after being clamped, and the processing effect is good.

[0066] It can process two shock absorber towers 100, one on the left and one on the right, at a time, thus completing the processing of a pair of shock absorber towers 100. It has high processing efficiency and good effect.

[0067] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
