Description

Technical Field

[0001] The utility model relates to the technical field of drilling holes in a slurry pump casing, in particular to a drilling device for a slurry pump casing. Background Art

[0002] Slurry pumps are widely used in mining, power plants, metallurgy, chemical engineering, building materials, and other technical fields to transport slurries containing solid particles. The volute is a core component and one of the flow passages most susceptible to wear during slurry transportation. The drilling device used in slurry pump volute production requires clamping and securing volutes of varying specifications before drilling.

[0003] Application No. CN202120642418.8 discloses a punching device for the production of slurry pump volutes. By moving the No. 1 L-shaped column, the distance between the clamps can be adjusted, which is suitable for the horizontal fixation of volutes of different lengths. By energizing the electromagnet, the metal block is adsorbed and fixed to the electromagnet, so that the L-shaped plate fixes the volute longitudinally, thereby tightening and fixing volutes of different specifications, improving the punching efficiency. By de-energizing the electromagnet, the No. 2 spring drives the L-shaped plate to release elastic potential energy. The micro-vibration generated when releasing the elastic potential energy facilitates the volute to fall off the L-shaped plate by itself, thereby improving the efficiency of material removal.

[0004] However, the punching device for producing the slurry pump volute disclosed in the above patent requires the volute to be placed between the clamps before being clamped by the clamps, then moved close to the L-shaped column, and finally powered on the electromagnet to clamp it. This is very troublesome, and the volute cannot be clamped quickly and cannot be clamped at different heights. It can only clamp the volute at a certain height. Utility Model Content

[0005] The purpose of the present utility model is to provide a punching device for a slurry pump casing. The punching device for a slurry pump casing disclosed in the present utility model can quickly clamp the pump casing to be punched through the clamping frames on the left and right sides and the magnetically attracted side strips as a whole, in cooperation with the electromagnet plate, and can adjust the height of the pressing piece in the clamping frame according to the height of the pump casing to be clamped, so as to adapt to the rapid clamping of pump casings of different heights and sizes, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a punching device for a slurry pump casing, comprising a frame, an electromagnet plate fixedly mounted on the top of the lower seat of the frame, a clamping frame connected to the left and right ends of the top of the electromagnet plate, the clamping frame is L-shaped and the opening is facing the axis of the workbench at the top of the lower seat of the frame, side strips are fixedly mounted on the bottom edges of the side panels of the clamping frame, the side strips are made of a metal material that can be magnetically attracted, a screw hole is opened in the center of the top plate of the clamping frame and a screw is threadedly connected to the inner side wall of the screw hole, and a pressing plate is installed at the bottom of the screw.

[0007] Preferably, a screw head is fixedly connected to the top of the screw rod, and the screw head is in the shape of a five-petal flower for easy screwing.

[0008] Preferably, a scale frame is installed on the top of the lower seat of the rack.

[0009] Preferably, a vertical scale bar is installed at the front end of the clamping frame side plate.

[0010] Preferably, a transverse linear displacement drive assembly is installed at the bottom of the upper seat of the frame, and a power output end at the bottom of the transverse linear displacement drive assembly is connected to a power input end of the longitudinal linear displacement drive assembly.

[0011] Preferably, an electric telescopic rod is installed at the power output end of the bottom of the longitudinal linear displacement drive assembly, and a punching assembly is installed at the bottom of the electric telescopic rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 3 The figure shows a punching device for a slurry pump casing, comprising a frame 1, an electromagnetic plate 2 fixedly mounted on the top of the lower seat of the frame 1, and clamping frames 8 connected to the left and right ends of the top of the electromagnetic plate 2. The clamping frame 8 is L-shaped and the opening is facing the axis of the workbench on the top of the lower seat of the frame 1. Side strips 9 are fixedly mounted on the bottom edges of the side panels of the clamping frame 8. The side strips 9 are made of a metal material that can be magnetically attracted. A screw hole is provided at the center of the top plate of the clamping frame 8 and a screw 12 is threadedly connected to the inner side wall of the screw hole. A pressing piece 11 is installed at the bottom of the screw 12. The punching device for the slurry pump casing disclosed in the utility model can quickly clamp the pump casing to be punched through the clamping frames 8 on the left and right sides and the magnetic side strips 9 as a whole, in conjunction with the electromagnetic plate 2, and the height of the pressing piece 11 in the clamping frame 8 can be adjusted according to the height of the pump casing to be clamped, so as to adapt to the rapid clamping of pump casings of different heights and sizes.

[0020] Furthermore, a screwing head 13 is fixedly connected to the top of the screw rod 12, and the screwing head 13 is in the shape of a five-petal flower for easy screwing; further, a scale frame 3 is installed on the top of the lower seat of the frame 1, which is convenient for checking the position of the clamping frame 8; further, a vertical scale bar 10 is installed at the front end of the side panel of the clamping frame 8, which is convenient for checking the height of the pressing piece 11; further, a transverse linear displacement drive component 5 is installed at the bottom of the upper seat of the frame 1, and the power output end at the bottom of the transverse linear displacement drive component 5 is connected to the power input end of the longitudinal linear displacement drive component 4 for convenient driving; further, an electric telescopic rod 6 is installed at the power output end at the bottom of the longitudinal linear displacement drive component 4, and a punching component 7 is installed at the bottom of the electric telescopic rod 6 for convenient punching.

[0021] In this solution, when in use, the drilling device for the pump casing of the slurry pump disclosed by the utility model can quickly clamp the pump casing to be punched through the clamping frames 8 on the left and right sides and the magnetically attracted side strips 9 as a whole, in conjunction with the electromagnet plate 2, and the height of the pressing piece 11 in the clamping frame 8 can be adjusted according to the height of the pump casing to be clamped, so as to adapt to the rapid clamping of pump casings of different heights and sizes. Before clamping, according to the height of the volute to be clamped, the screw head 13 is first screwed to make the screw 12 and the pressing piece 11 rotate up or down to the required height, so that the volutes of the same height can be quickly clamped in batches. The clamping frame 8 is opened, and the volute is placed on the electromagnet plate 2. The left and right clamping frames 8 are used to clamp the left and right ends of the volute respectively. The external power supply is used, and the electromagnet plate 2 is turned on by an external switch. Since the bottom edges of the side panels of the clamping frame 8 are fixedly installed with side strips 9, the side strips 9 are made of a metal material that can be magnetically attracted. The electromagnet plate 2 can firmly magnetically attract the clamping frame 8 so that the clamping frame 8 can quickly clamp the volute (the electromagnet plate 2, the longitudinal linear displacement drive component 4, the transverse linear displacement drive component 5, the electric telescopic rod 6 and the punching component 7 are all existing products on the market).
