With the development of the new energy field, they are also used in vehicle battery temperature management as part of a heat pump air conditioner. The cylinder block is one of the core components of the compressor. According to different installation positions, corresponding installation holes need to be machined on the reserved installation lugs of the cylinder block. The installation holes may be straight holes, strip holes or threaded holes, etc. according to different installation environments and requirements. At the same time, according to the structural design of different vehicle models, some installation states require inclined threaded holes to be designed on the lugs of the cylinder block to cooperate with the strip-shaped installation holes of the vehicle frame and be fixed by bolt connection.

[0091] A buckle cover 42 is buckled on the upper ends of the four columns 41 and fixedly connected to the upper ends of the columns 41; the buckle cover 42 is located directly above the lower limit seat 32; after the hinge plate 31 rotates, when the limit frame rotates and topples around the hinge seat, the outer surface of the buckle cover 42 abuts against the fixed component; the limit cylinder 5 is vertically arranged at the upper end of the buckle cover 42, and the telescopic end of the limit cylinder 5 passes through the bottom of the buckle cover 42 and is located inside the buckle cover 42.

[0092] The arrangement of the columns 41 can not only ensure the structural strength of the limit frame, but also provide space for taking and placing the cylinder body to be tapped with inclined holes, and at the same time will not interfere with the lifting of the tapping head 91.

[0093] In this embodiment, a lower groove 11 is provided on the lower surface of the bottom plate 1 in the area directly opposite to the inclined seat; a strip-shaped groove 12 is provided on the upper surface of the bottom plate 1 in the area directly opposite to the inclined seat; at least two mounting holes 13 communicating with the lower groove 11 are provided in the strip-shaped groove 12;

[0094] The inclined seat includes:

[0095] A base 71 is arranged in the strip-shaped groove 12, the side surface is closely attached to the side wall of the strip-shaped groove 12, and the base 71 and the bottom plate 1 are fixedly connected together by bolts passing through the base 71 and the mounting holes 13;

[0096] The seat post 72 is vertically arranged on the base 71 through screws; the fixing assembly is arranged at the top end of the seat post 72.

[0097] The lower groove 11 is provided to keep the bottom plate 1 horizontal, and the strip groove 12 can accommodate the base 71 and has a certain limiting effect on the base 71.

[0098] In this embodiment, a strip hole 711 is provided on the base 71, and the axis of the strip hole 711 is collinear with the connection line of the two inclined seats; the base 71 can move in the strip groove 12 through the strip hole 711;

[0099] Matching strip teeth (too small in size and thus not shown in the figure) are provided on the lower surface of the base 71 and the bottom of the strip groove 12, and the axis of the strip teeth is perpendicular to the axis of the strip hole 711; the width of the strip teeth does not exceed 0.1 mm.

[0100] As the position of the base 71 will shift slightly during use, at this time, the position of the base 71 in the strip groove 12 can be adjusted through the strip hole 711, and the base 71 can be prevented from sliding in the strip groove 12 through the strip teeth.

[0101] In this embodiment, an accommodation cavity 721 is provided inside the seat post 72;

[0102] The fixing assembly includes:

[0103] An electromagnet 81, arranged in the accommodation cavity 721; the limiting frame is made of magnetic material and will be attracted by magnetic force when the electromagnet 81 is energized; the base 71 is made of engineering plastic;

[0104] A contact seat 82, arranged on the upper surface of the base 71, the cross-section of the upper part of the contact seat 82 is hemispherical, and the transverse axis of the contact seat 82 is parallel to the rotation axis of the hinge seat.

[0105] Through the magnetic adsorption of the electromagnet 81 on the buckle cover 42, the rotation angle of the hinge plate 31 is ensured to be stable. At the same time, the shape design of the contact seat 82 can enable the seat post 72 to still maintain stable contact and abutment with the buckle cover 42 when adjusting the position of the seat post 72 on the bottom plate 1.

[0106] The tapping clamping device for the inclined hole of the cylinder block in this embodiment is used as follows. A tapping device that cooperates with the punching position of the utility model is used, such as Figure 6 the tapping lathe 9 in it, which has two vertically lifting turning heads 91, respectively facing the two inclined seat areas of the present utility model.

[0107] Control the retraction of the limit cylinder 5, place the cylinder block to be tapped obliquely through the column 41 into the lower limit seat 32, and then control the extension of the limit cylinder 5 so that the upper limit seat 6 clamps and fixes the limit cylinder 5.

[0108] Then tilt the limit frame to one side, as Figure 6 shown, so that the buckle cover 42 abuts against the contact seat 82, and then energize the electromagnet 81 so that the electromagnet 81 generates a magnetic force to adsorb and fix the buckle cover 42. Subsequently, control the lowering of the turning head 91 of the tapping lathe 9 to drill and tap the cylinder block.

[0109] When the drilling and tapping on one side of the cylinder block are completed, the electromagnet 81 is de-energized, then turn the limit frame to the other side, and then complete the drilling and tapping as above. If it is necessary to drill and tap multiple faces of the cylinder block, only need to turn the limit frame so that the inner plate 25 rotates within the annular plate 24 until the spherical top convex 274 matches the spherical groove set at a predetermined angle. At this time, the cylinder block has rotated a predetermined angle, and then repeat the above-mentioned tilting of the limit frame to complete the drilling and tapping.

[0110] Finally, control the retraction of the control limit cylinder 5 and take out the cylinder block that has completed drilling and tapping.

[0116] The quick clamp 85 is arranged on the base 71. When the limit frame is tilted along with the hinge plate 31, the ear plate 83 is flush with the upper surface of the base 71. The ear plate 83 is sleeved on the limit post 84 through the limit hole 831, and the quick clamp 85 fixedly connects the ear plate 83 and the base 71 relatively.

[0117] The buckle cover 42 and the seat rod 72 are relatively fixed through the ear plate 83 as a connecting piece. In this scheme, the seat rod 72 cannot be adjusted within a large range on the bottom plate 1, otherwise the ear plate 83 will not be able to cooperate with the limit post 84 on the seat rod 72. The quick clamp 85 can adopt a manual mechanical structure quick clamp 85 or can also adopt a spin-press cylinder controlled automatically.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them.
