[0023] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0024] See Figures 1 to 3This embodiment provides a positioning and clamping device for vehicle compressor housings, which can be used simultaneously for positioning and clamping two vehicle compressor housings (hereinafter referred to as workpieces). The device includes a base plate 1, on which are provided a rotor hole positioning mechanism, a bearing hole positioning mechanism, a first bottom support mechanism, a second bottom support mechanism, and a pressure plate locking mechanism.

[0025] See Figures 1 to 3 The rotor hole positioning mechanism includes: four first guide shafts 2, two positioning pressure plates 9, and two first positioning cores 5.

[0026] Four first guide shafts 2 are symmetrically arranged on the left and right sides, with two on each side. The structural diagram of the first guide shaft 2 is shown in Figure 4. The first guide shaft 2 is installed and fixed on the base plate 1 by bolts. The first guide shaft 2 is used to install the first positioning core 5 and the positioning pressure plate 9.

[0027] The structure of the first positioning core 5 is shown below. Figure 1 and Figure 6 The first positioning core 5 is used for center positioning of the rotor hole of the workpiece, and its shape is set according to the rotor hole of the workpiece. See also Figure 1 A first positioning core 5 is installed and fixed on one of the first guide shafts 2 on each side. The positions of the two first positioning cores 5 are not symmetrical.

[0028] See Figure 7 The positioning plate 9 has horizontally extending protrusions 92 at both ends. Two bolt holes 91 are located in the middle of the positioning plate 9. (See also...) Figure 4 A bolt connection hole 21 is provided on the top surface of the first guide shaft 2. (See also...) Figure 2 or Figure 3 The single positioning plate 9 is connected and fixed to the top of the two first guide shafts 2 on one side, specifically by bolts. Furthermore, the lower end of the positioning plate 9 has a structure that mates with the rotor hole of the workpiece, so as to achieve effective positioning and locking of the positioning plate with the rotor hole of the workpiece.

[0029] See Figure 1 The bearing hole positioning mechanism includes: two second guide shafts 3, two second positioning cores 4, two compression springs 8, and two stops 12.

[0030] See Figure 1 Two second guide shafts 3 are located between the first guide shafts 2 on the left and right sides, and the two second guide shafts 3 are symmetrically arranged on the left and right sides. See [link to details regarding the structure of the second guide shafts 3] for details. Figure 1 and Figure 5 The base plate 1 has two circular holes for embedding the second guide shaft 3. The lower end disc structure of the second guide shaft 3 is embedded and fixed in the circular holes.

[0031] Two second positioning cores 4 are respectively fitted onto two second guide shafts 3. Each second positioning core 4 has a frustum structure with a through hole in the center. The end face with the smaller radius is the upper end face, and the end face with the larger radius is the lower end face. Two compression springs 8 are respectively fitted onto the two second guide shafts 3 and located below the second positioning cores 4, contacting and abutting against the lower end face of the second positioning cores 4. Two stops 12 are respectively installed and fixed onto the two second guide shafts 3 and located above the second positioning cores 4, serving to block the second positioning cores 4. Because the bearing holes of the workpieces vary in diameter when in a blank state, the frustum structure of the second positioning core 4 and the presence of compression springs 8 below it allow the second positioning core 4 to float up and down, better adapting to the bearing holes of different batches of workpieces to achieve effective contact and precise positioning.

[0032] See Figure 1 The first bottom support mechanism consists of two sets, located in the middle of the base plate 1, arranged symmetrically front to back. The two sets of first bottom support mechanisms respectively support the bottom surfaces of the inner sides of the left and right workpieces. Each set of first bottom support mechanisms is equipped with a first leveling block 6 and a first height adjusting bolt. The first leveling block 6 has multiple bolt holes, and each set of first bottom support mechanisms has two first height adjusting bolts 14, which are bolted to the first leveling block 6. The first height adjusting bolt 14 can adjust its insertion depth into the bolt hole through a threaded connection with the first leveling block 6, thereby adjusting the support height.

[0033] See Figure 1 The second bottom support mechanism consists of four sets, each symmetrically positioned beside the four first guide shafts 2. These four sets support the bottom surfaces of the outer sides of the two workpieces. Each set includes a second leveling block 7 and a second height adjusting bolt 15. The second leveling block 7 has multiple bolt holes, and each set includes one second height adjusting bolt 15, which is bolted to the second leveling block 7. The second height adjusting bolt 15 can adjust its insertion depth into the bolt hole through a threaded connection with the second leveling block 7, thereby adjusting the support height.

[0034] See Figure 1 and Figure 2The pressure plate locking mechanism is located in the middle of the base plate 1 and is used to simultaneously lock two workpieces. The pressure plate locking mechanism includes a central screw 11, support screws 16, and a pressure plate body 10. The central screw 11 is fixed at the center of the base plate 1. The support screws 16 are fixed to the base plate 1 and arranged symmetrically about the central screw 11. A bolt hole for connecting to the upper end of the central screw 11 is provided in the middle of the pressure plate body 10, and both ends of the pressure plate body 10 press against the planes of the two workpieces respectively.

[0035] See Figure 3 In the positioning and clamping device for the vehicle compressor housing in this embodiment, the side of the base plate 1 is also provided with side bolt holes for mounting positioning side plates 13. There are two positioning side plates 13, which are used for side positioning of two workpieces respectively. The positioning side plates 13 are provided with multiple bolt connection holes. The lower end of the positioning side plate 13 is connected to the side bolt holes on the base plate 1, and the upper end and middle part of the positioning side plate 13 are bolted to the workpieces.

[0036] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
