DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 The hydraulic fixture for drilling holes in the air conditioning compressor bracket shown is used for processing Figure 3 The air-conditioning compressor bracket a shown includes a turntable base 1, a base plate 2, and a fixture assembly station.

[0033] The base plate is arranged on the turntable base, and a pipeline is arranged inside the base plate. The pipeline inside the base plate is connected with the gas-liquid supply interface of the turntable base. Two left and right clamp assembly stations are arranged parallel to the top surface of the base plate, and the gas-liquid supply interface of the clamp assembly station is connected with the pipeline of the base plate.

[0034] A single fixture assembly station includes:

[0035] A side hole processing slot 203 is provided on the base plate, and the side hole processing slot is an isosceles trapezoid, wherein the long side is provided on the long side of the base plate, and the short side is transitioned to the beveled side with a rounded corner;

[0036] A point positioning fixture is set on the base plate outside the bevel of the side hole processing slot, wherein the left bevel is called the first point positioning fixture, and the right bevel is called the third point positioning fixture;

[0037] A mounting countersunk hole 205 is provided on the base plate, and the mounting countersunk hole 205 is a rounded rectangular hole, and the second point positioning fixture is set based on this hole;

[0038] A first horizontal support 401 is provided between the first point positioning fixture and the second point positioning fixture; a second horizontal support 402 is provided between the third point positioning fixture and the second point positioning fixture;

[0039] In the area on the base plate surrounded by the side hole processing slot, the first point positioning fixture, the second point positioning fixture, and the third point positioning fixture, a plurality of processing through holes are arranged.

[0040] The first point positioning fixture, the second point positioning fixture and the third point positioning fixture each include a lever cylinder, a hollow positioning stud, a coarse positioning block and a water spray joint;

[0041] The working end of the lever block of the lever cylinder adopts a rounded isosceles triangle, and the working end covers the hollow positioning stud when in the working state;

[0042] A circular arc groove is arranged on the vertical surface of the coarse positioning block;

[0043] The axis of the water spray joint intersects with the vertical line of the hollow positioning stud;

[0044] The diameter of the middle through hole of the hollow positioning stud is 1.5 mm, and the middle through hole is connected to the pipeline in the base plate.

[0045] exist Figure 4 The figure shows the matching relationship between the first lever cylinder 311 and the first hollow positioning stud 313 in the first point positioning fixture. It can be seen from the figure that when the first lever cylinder is in a downward pressure state, the first lever cylinder and the first hollow positioning stud cooperate with each other to compact. By passing gas into the first hollow positioning stud, the degree of air leakage can be determined from the barometer, thereby determining whether it is clamped. The same applies to other positioning fixtures.

[0046] The first coarse positioning block 312 is arranged at the corner end of the air-conditioning compressor bracket. The arc groove on the first coarse positioning block is conducive to the cooperation with the air-conditioning compressor bracket and reduces the shaking of the air-conditioning compressor bracket. At the same time, the first coarse positioning block is made of plastic and has a certain adjustable elasticity.

[0047] from Figure 4 It can also be seen that due to the presence of the mounting countersunk hole 205, the actual working point of the second lever cylinder 321 in the second point positioning fixture is also vertically offset downward to adapt to the air conditioner compressor bracket. By adjusting the depth of the mounting countersunk hole 205, or adding a pad in the mounting countersunk hole 205, in combination with the second empty positioning stud, it can adapt to different air conditioner compressor brackets.

[0048] The third coarse positioning block 332 is arranged at the other corner end of the air-conditioning compressor bracket corresponding to the first coarse positioning block, and cooperates with the third lever cylinder 331 and the third hollow positioning stud 333 to position and fix the other corner end of the air-conditioning compressor bracket.

[0049] The air-conditioning compressor bracket is fixed at three points by using the first point positioning fixture, the second point positioning fixture and the third point positioning fixture together, and two horizontal supports are used to ensure that the overall fixation of the fixture is stable to prevent the air-conditioning compressor bracket from falling off when the turntable base rotates.

[0050] An arc-shaped insertion hole 201 is arranged horizontally on the vertical surface of the short side of the side hole processing groove of the base plate; the arc end point of the arc-shaped insertion hole is arranged on the top surface of the base plate; the arc-shaped insertion hole 201 can provide a placement position for the side special-shaped protrusion on the air-conditioning compressor bracket.

[0051] The number of processed through holes is 4, among which the processed through hole between the first horizontal support and the second point positioning fixture is a long waist shape 204;

[0052] The other three processed through holes are all circular, and the diameter of the arc edge of the long waist shape is equal to the diameter of the other processed through holes;

[0053] One of the processing through holes is cut into the arc-shaped insertion hole 201 from the top surface, and the reference numeral of this processing through hole is 202.

[0054] The first horizontal support 401 and the second horizontal support 402 both include a base and a telescopic horizontal screw rod. The telescopic horizontal screw rod is inserted into the base. The base includes a return spring. One end of the return spring cooperates with the telescopic horizontal screw rod, and the other end abuts against the base.
