Description

Technical Field

[0001] The utility model relates to the field of automobile parts processing, in particular to an anti-offset punching device for an automobile air suspension piston cylinder block. Background Art

[0002] An air suspension utilizes the increasing rigidity of the sealed gas in the air spring under compression, that is, as the air spring is continuously compressed, its stiffness gradually increases. At the same time, the internal gas is pressed into or discharged as the air spring is compressed or stretched, resulting in the air suspension system having near-ideal dynamic elastic characteristics. Therefore, an anti-offset punching device for an automobile air suspension piston cylinder block is required.

[0003] The Chinese utility model with the publication number CN220216416U discloses an anti-offset punching device for an automobile air suspension piston cylinder block, which includes a base.

Clamp the left and right sides of the cylinder block on the bearing block 3 through the first clamping mechanism 4. The first clamping mechanism 4 includes two clamping components symmetrically arranged on the left and right sides of the bearing block 3. The clamping component includes a rotating seat 41, a side plate 42 and a pushing cylinder 43. There are two rotating seats 41. A first hinge seat 44 is provided on the back of the side plate 42. A driven shaft 45 is rotatably installed on the first hinge seat 44. Rotating shafts 46 are provided on both sides of one end of the side plate 42. A hinge joint 47 is installed at the tail end of the pushing cylinder 43. A second hinge seat 22 is provided on the top of the placing rack 2. The two rotating seats 41 are symmetrically arranged on the side wall of the bearing block 3. The side plate 42 is rotatably arranged on the two rotating seats 41 through the rotating shafts 46. The hinge joint 47 is hinged on the second hinge seat 22. The output end of the pushing cylinder 43 is fixedly connected to the side wall of the driven shaft 45.

[0027] The driven shaft 45 is driven to move by the driving cylinder 43. The driven shaft 45 drives the first hinge seat 44 to move.

[0028] Furthermore, anti-slip lines are provided at the front part of the side plate 42. Through the anti-slip lines, the friction between the side plate 42 and the side wall of the cylinder block can be increased, and the stability can be improved.

[0029] The front and rear sides of the cylinder block are clamped by the second clamping mechanism 5. The second clamping mechanism 5 includes a bidirectional lead screw 51 and a rotating motor 52. Two symmetrically arranged T-shaped blocks 53 are screwed on the bidirectional lead screw 51. A detachable abutting block 54 is provided at the top of the T-shaped block 53.

[0036] Furthermore, a first arc surface 631 is provided at the bottom of the downward pressing block 63, and a second arc surface 31 is provided at the top of the bearing block 3. The first arc surface 631 can increase the contact area between the downward pressing block 63 and the cylinder block, improving the stability of pressing the cylinder block downward. The second arc surface 31 can increase the contact area between the bearing block 3 and the cylinder block, improving the stability of the bearing block 3 in bearing the cylinder block.

[0037] Still further, anti-slip lines are provided in both the first arc surface 631 and the second arc surface 31, improving the friction with the cylinder block and enhancing the stability.

[0038] Through the positioning of the front, back, left, right and top of the cylinder block by the first clamping mechanism 4, the second clamping mechanism 5 and the downward pressing mechanism 6, the cylinder block can be prevented from shifting during punching. After the positioning of the cylinder block is completed, the downward pushing cylinder 12 drives the mounting bracket to move downward. At the same time, the drilling motor 14 drives the drill bit 15 to rotate to perform punching operations on the cylinder block.

[0039] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
