Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile machining fixtures, in particular to a rotation positioning detection mechanism for aluminum profile machining fixtures. Background Art

[0002] In some working conditions (such as as raw materials for welding battery box frames), extruded straight aluminum profiles have higher precision requirements for the processing of the blank ends, which cannot be achieved by general shearing machines or sawing machines for cutting materials, and the ends have strict relative position requirements for the reference holes for subsequent processing.

[0003] In order to ensure this position, a two-sequence processing method is generally adopted. First, the elements other than the end face are positioned using the blank A / B / C reference to process the reference hole, and then the reference hole is used for positioning. After clamping, the end faces at both ends are processed. In the existing technology, the processing time is long, the stability of the processing size is not high, and clamping will cause pressure damage to the end face of the aluminum profile. Summary of the invention

The rotating oil cylinder, the positioning support, and the copper pressure plate are connected through screws and locking nuts.

[0008] Preferably, the copper pressing plate is provided with a detection hole for introducing compressed air through an external pipe, which is located at the place in contact with the boundary of the aluminum profile, and the compressed air is used as an air source for clamping into place and position detection.

[0009] Preferably, the rotary cylinder model is LHA0480-CR.

[0010] Preferably, the cross section of the positioning support is an inverted T-shape, comprising a first part and a second part, wherein the first part is used to connect to the rotary cylinder, and the second part is used to connect to the processing table to play a supporting role.

[0011] Preferably, the cross-section of the rotating main body pressure plate is stair-shaped, including a third part and a fourth part, the edge of the third part is used to place the copper pressure plate, and the fourth part is used to connect with the rotating cylinder.

[0012] Preferably, the aluminum profile is hollow and has a rectangular cross-section.

[0013] The beneficial effects of the utility model are:

[0014] By adding this rotating positioning detection mechanism to the fixture, the positioning, clamping and in-place detection before aluminum profile processing can be realized. At the same time, after the reference hole is processed, the clamping block is loosened, and then the processing of the original blank reference of the profile end face is completed, so that the aluminum profile can be processed once under the corresponding working conditions, the processing cycle is shortened, and the processing size stability is improved, while also avoiding the pressure damage to the aluminum profile end face caused by clamping. The output efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in 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.

[0022] See also Figure 1-6 , the utility model provides a technical solution:

[0023] A rotation positioning detection mechanism for an aluminum profile machining fixture comprises: a rotating pressure plate body 1, a positioning support 3, a rotating oil cylinder 2, and a copper pressure plate 5 are provided on one side of the rotating pressure plate body 1, a positioning support 3 is provided on one side of the rotating oil cylinder 2, and a locking nut 4 is provided on the side of the rotating pressure plate body 1 opposite to the rotating oil cylinder 2, wherein the rotating pressure plate body 1 is made of 45# steel.

[0024] The copper pressure plate 5 is close to the top of the rotating pressure plate body 1, and the end opposite to the rotating pressure plate body 1 is in contact with the end face of the aluminum profile 7, and is used for positioning, clamping and in-place detection of the aluminum profile 7 before processing. The rotating cylinder 2, the positioning support 3, and the copper pressure plate 5 are connected through screws and locking nuts 4, so that the three are kept in a tightened state and are placed in staggered positions.

[0025] The copper pressing plate 5 is provided with a detection hole 6 for introducing compressed air through an external pipe, which is located at the place where it contacts the boundary of the aluminum profile 7. Compressed air of about 2 bar is introduced through the external pipe and used as an air source for clamping in place and position detection.

[0026] The rotary cylinder 2 model LHA0480-CR is available on the market.

[0027] The cross section of the positioning support 3 is an inverted T-shape, and includes a first part 31 and a second part 32. The first part 31 and the second part 32 are integrally formed. The first part 31 is used to connect with the rotating cylinder 2, and the second part 32 is used to connect with the processing table to play a supporting role.

[0028] The rotating main body pressing plate 1 has a staircase-shaped cross section and includes a third portion 51 and a fourth portion 52 . The edge of the third portion 51 is used to place the copper pressing plate 5 , and the fourth portion 52 is used to connect with the rotating cylinder 2 .

[0029] The cross section of the copper pressing plate 5 is rectangular, and its area is equal to the cross section area of ​​the third portion 51 , so as to avoid damage to the aluminum profile 7 during pressing.

[0030] Working principle: In the prior art, when processing the aluminum profile 7, fixed iron positioning blocks are provided at both ends. In the utility model, the fixed iron positioning blocks in the general design are replaced by the rotating positioning detection mechanism, and the positioning and rotating mechanism of the utility model is provided at both ends of the aluminum profile 7, wherein the rotating cylinder 2 model is LHA0480-CR, the rotating pressure plate body 1 is made of 45# steel, the copper pressure plate 5 has a detection hole 6 on the pressing surface, and compressed air of about 2 bar is introduced through external piping, which is used as an air source for clamping into place and position detection.

[0031] The air source for airtight monitoring is connected by an external hose to the chuck of the combination of the rotating pressure plate body 1 and the copper pressure plate 5, that is, the position where the rotating pressure plate body 1 and the copper pressure plate 5 contact and overlap. When the chuck is clamped in place with the aluminum profile 7, the air pressure drop will not exceed 0.3 bar. When it contacts the hollow of the aluminum profile 7, the air pressure will drop rapidly to 0. By monitoring the pressure changes in the air circuit after clamping, it is determined whether the part is clamped to the boundary of the aluminum profile 7. In the loading state, the rotating cylinder 2 is in the clamping position. After manual loading, the aluminum profile 7 is aligned with the copper pressure plate 5, and the cylinder of the rotating positioning detection mechanism on the other end face is clamped to ensure the clamping state of the workpiece during processing. At the same time, the pressure changes in the air circuit after clamping are monitored to check and confirm the positioning state of the aluminum profile 7 on the copper pressure plate 5. After the normal processing elements of each aluminum profile 7 are completed, the rotating cylinders at both ends are moved to a loose state.
