The main air pipe 8 is rotatably installed at one end of the transverse axis 7 away from the clamping assembly. The main air pipe 8 is connected to the air distribution cavity 42. The end of the main air pipe 8 away from the transverse axis 7 is connected to the booster pump 9 fixed on the stand 10.

The elastic supporting force of the spring B45 on the slide plate A44 is adjusted to adjust the pressure relief pressure (after the clamping of the splint 13 exceeds the limit, the slide plate A44 moves to relieve pressure, avoiding the clamping force of the splint 13 on the outer protective shell of the gear pump exceeding the limit, and at the same time it is easier to adjust the pressure range of the booster pump 9).

[0027] like Figure 1-7 As shown, as a preferred embodiment of the present invention, since the upper punching assembly 11 and the lower punching assembly 16 have the same structure, the upper punching assembly 11 is taken as an example for description, and the details are as follows: The upper drilling assembly 11 includes a horizontal telescopic cylinder 18 fixed on the stand 10, a vertical cylinder 22 is fixed to the end of the telescopic mandrel of the horizontal telescopic cylinder 18, a universal ball shell 26 is fixed to the inner side of the vertical cylinder 22 through a circumferentially distributed support shaft A25, a universal ball 27 is rotatably installed in the universal ball shell 26, a drilling telescopic cylinder 19 is passed through and fixed in the universal ball 27, a motor B23 is fixed to the end of the telescopic mandrel of the drilling telescopic cylinder 19, and a drill rod 24 is detachably fixed to the output end of the motor B23; an angle adjustment ring 28 is fixed to the end of the vertical cylinder 22 away from the clamping assembly, and the angle adjustment ring An adjustable anti-slip sliding slider 21 is provided on 28, and the upper cross-section of the angle adjustment ring 28 can be arranged as a circle, and the lower cross-section can be arranged as a rectangle, so that the slide groove 35 at the lower part of the slider 21 can be slidably connected with the angle adjustment ring 28 to achieve anti-slip sliding; an installation opening 32 is opened on the upper part of the slider 21, and a ring 31 is provided in the installation opening 32, and support shafts B33 are fixed on both sides of the ring 31, and one end of the support shaft B33 away from the ring 31 is rotatably connected to the slider 21, and an angle adjustment rod 20 is adjustable and slidable in the ring 31, and one end of the angle adjustment rod 20 is hinged to the punching telescopic cylinder 19.

[0028] The sliding adjustment of the angle adjustment rod 20 and the slider 21 can be achieved in the following two ways: First, if Figure 4 As shown, the slider 21 is provided with a fastening bolt A29 for locking the slider 21 on the angle adjustment ring 28; the collar 31 is provided with a fastening bolt B30 for locking and fixing the angle adjustment rod 20, and the two bolts are used to achieve separate fixation.

[0029] Second, if Figure 6 and 7As shown, the slider 21 is threadedly connected with a screw rod A37, the outer end of the screw rod A37 is fixed with a nut A34, the inner end of the screw rod A37 extends into the support shaft B33, the inner cavity of the support shaft B33 is also connected with the inner cavity of the collar 31, and the screw rod A37 and the support shaft B33 are arranged with a gap or connected in rotation; the slider 21 is also provided with an active cavity 38, and a wedge block 36 is slidably provided in the active cavity 38, and the wedge block 36 is also rotatably connected with the screw rod A37, and the slider 21 is also slidably provided with a fixing rod 41, one end of the fixing rod 41 is slidably matched with the wedge block 36, and a fixing block 39 is also fixed on the fixing rod 41 A spring A40 is fixed on the fixed block 39, and the other end of the spring A40 is fixedly connected to the end of the active cavity 38; in the process of the inner end of the screw A37 being abutted and fixed to the angle adjustment rod 20, the wedge block 36 pushes the fixing rod 41 to move, so that the screw A37 fixes the angle adjustment rod 20 while the fixing rod 41 is abutted and fixed to the angle adjustment ring 28; when the screw A37 is separated from the angle adjustment rod 20, the fixing rod 41 is separated from the angle adjustment ring 28 under the elastic force of the spring A40; this method can realize the simultaneous locking of the angle adjustment rod 20 and the slider 21 with one bolt, which is convenient and quick.

[0030] The above embodiment of the present invention provides a gear pump outer protective shell punching processing equipment, the working principle is as follows: First, the booster pump 9 in the control assembly supplies air to the air distribution cavity 42 inside the horizontal axis 7, and then supplies compressed air to each clamping cylinder 15 through the bronchial tube 14. The clamping cylinder 15 drives the arc clamping plate 13 thereon to move, thereby firmly clamping and fixing the outer protective shell of the gear pump to be processed.

[0031] Once the outer protective shell of the gear pump is correctly clamped, the horizontal axis 7 can be driven to rotate through the steering assembly (motor A4, main gear 17 and slave gear 6) to adjust the position of the outer protective shell of the gear pump relative to the upper punching assembly 11 and the lower punching assembly 16 to ensure that the punching operation can be carried out at the preset angle and position.

[0032] For each drilling assembly, the horizontal telescopic cylinder 18 can move the vertical cylinder 22 in the horizontal direction, and the universal ball 27 allows the drill rod 24 to freely adjust the angle within a certain range. Through the combination of the slider 21 on the angle adjustment ring 28 and the angle adjustment rod 20, the specific angle of the drill rod 24 can be adjusted so that the drill rod 24 can accurately align with the predetermined drilling point.

[0033] When all settings are completed, the punching telescopic cylinder 19 is started to push the motor B23 and the drill rod 24 thereon forward to start the punching operation. The motor B23 drives the drill rod 24 to rotate to achieve the punching process. The upper punching assembly 11 and the lower punching assembly 16 can work simultaneously or sequentially as needed to improve efficiency.

[0034] In addition, if the clamping force on the outer protective shell of the gear pump exceeds the set value, the spring B45 in the pressure relief chamber 51 will be compressed, prompting the slide A44 to move and start the pressure relief to prevent excessive clamping force from damaging the workpiece or the equipment itself.

[0035] In summary, the present invention realizes efficient, accurate and multifunctional punching processing of the outer protective casing of gear pumps of different shapes through flexible clamping, steering and double-station punching component design.

[0036] The PLC controller disclosed in the prior art can be used to control each component. The model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.

[0037] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
