Technical Field

[0001] The utility model relates to the technical field of automobile parts positioning fixtures, in particular to an automobile middle frame positioning fixture structure. Background Art

[0002] When processing frame structure parts such as automobile door frames, they need to be fully fixed by positioning fixtures, and the positioning fixtures specifically use clamping cylinders to drive the pressure head to press the frame parts. For example, Chinese Patent 202021061140.7 discloses a welding and grinding jig for automobile door frames, which includes at least two sets of positioning components, and the two sets of automobile door frames are cross-fixed on the positioning components. Each set of positioning components includes an upper corner positioning component and a lower corner positioning component. The upper corner positioning component includes a first corner clamping device, an adjustment middle support block, and a lower support block. A positioning groove for placing the corner of the automobile door frame is formed between the first corner clamping device, the adjustment middle support block, and the lower support block. The adjustment middle support block and the lower support block are supported at the bottom of the corner of the automobile door frame and clamped from the top by the first corner clamping device.

[0003] In the existing positioning fixture, when the automobile middle frame is pressed and positioned by the pressing block, the automobile middle frame is easily squeezed and deformed, which affects the subsequent use. Utility Model Content

[0007] The pressing cylinder is fixedly installed on the base plate. A pressing block is arranged on the piston rod of the pressing cylinder, and a supporting rod is arranged below the pressing block.

[0008] As a further description of the above technical solution:

[0009] End plates arranged symmetrically are provided at both ends of the base plate.

[0010] As a further description of the above technical solution:

[0011] An end plate is fixedly mounted on the output shaft of the rotating electrical machine.

[0012] As a further description of the above technical solution:

[0013] The end plate is provided with a waist-shaped hole.

[0014] As a further description of the above technical solution:

[0015] A locking cylinder is also arranged on the base plate, and a locking block is arranged on the locking cylinder.

[0016] As a further description of the above technical solution:

[0017] An adjusting block is arranged on the locking block, and the adjusting block is threadedly connected to the locking block.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] 1. In the utility model, when the middle frame part is placed on the substrate, the first cushion block and the second cushion block contact the lower surface of the middle frame part, and the middle frame part is supported by the first cushion block and the second cushion block to form a suspended arrangement without contacting the substrate. This prevents the middle frame part from being squeezed and deformed by the substrate when it is pressed by the pressing block of the pressing cylinder. When the pressing block presses the middle frame part, the middle frame part is also supported by a support rod below to further prevent the middle frame part from being deformed.

[0020] 2. In the utility model, a locking cylinder is also provided on the base plate, and a locking block is provided on the locking cylinder. The locking cylinder can adjust the lifting and lowering of the locking block so that the locking block downwardly squeezes the middle frame parts to further position the middle frame parts. An adjustment block is provided on the locking block, and the adjustment block is threadedly connected to the locking block. The locking block can adjust the installation height by rotating, so as to flexibly adjust the bottom surface height of the locking block, compensate for the drive of the locking cylinder, so that the locking block precisely fits the middle frame parts and is accurately positioned.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See also Figure 1-3 The utility model provides a technical solution: a vehicle middle frame positioning fixture structure, comprising:

[0030] A substrate 1 is provided with a first cushion block 11 and a second cushion block 12, a rubber block 121 is provided on the surface of the second cushion block 12, a middle frame part 9 is placed on the substrate 1, and the second cushion block 12 contacts the middle frame part 9;

[0031] The pressing cylinder 2 is fixedly mounted on the base plate 1 . A pressing block 21 is arranged on the piston rod of the pressing cylinder 2 , and a supporting rod 22 is arranged below the pressing block 21 .

[0032] Both ends of the base plate 1 are provided with symmetrically arranged end plates 3, and the clamp can be installed in two ways.

[0033] The first installation method: an end plate 3 is fixedly installed on the output shaft of the rotating motor, so that the fixture can be rotated by the rotating motor, thereby improving the flexibility of processing the middle frame part 9.

[0034] Second installation method: a waist-shaped hole 31 is provided on the end plate 3. The substrate 1 can also be fixed through the waist-shaped hole 31 on the end plate 3, for example, the end plate 3 is fixed on the plane of the support frame, so as to facilitate adjustment of the installation position of the substrate 1 on the support frame.

[0035] The base plate 1 is also provided with a locking cylinder 4, and a locking block 41 is provided on the locking cylinder 4. The locking cylinder 4 can be raised and lowered by adjusting the locking block 41, so that the locking block 41 downwardly presses the middle frame part 9, and further positions the middle frame part 9.

[0036] The locking block 41 is provided with an adjustment block 411, which is threadedly connected to the locking block 41. The locking block 41 can be rotated to adjust the installation height, thereby flexibly adjusting the bottom height of the locking block 41, compensating for the drive of the locking cylinder 4, so that the locking block 41 is precisely fitted to the middle frame part 9 and accurately positioned.

[0037] Working principle: When the middle frame part 9 is placed on the substrate 1, the first cushion block 11 and the second cushion block 12 contact the lower surface of the middle frame part 9, and the middle frame part 9 is supported by the first cushion block 11 and the second cushion block 12 to form a suspended arrangement without contacting the substrate 1. This prevents the middle frame part 9 from being squeezed and deformed by the substrate 1 when it is pressed by the pressing block 21 of the pressing cylinder 2. When the pressing block 21 presses the middle frame part 9, the middle frame part 9 is also supported by the support rod 22 below to further prevent the middle frame part 9 from being deformed.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
