Description

A tooling for assembling a fixed connecting plate for a chemical pump base. Technical Fields

[0001] This utility model relates to the field of water pump processing equipment technology, and more specifically to a tooling for splicing a fixed connecting plate for a chemical pump base. Background Technology:

[0002] In existing chemical pumps, the pump body and drive motor are usually fixed on the bottom frame, and multiple connecting plates are usually welded to the side wall of the bottom frame. The connecting plates have through holes in the middle, and the bottom frame can be fixed by inserting bolts into the through holes of the connecting plates.

[0003] During the processing, the connecting plate needs to be manually welded and fixed to the corresponding side wall of the bottom frame. The existing method is to manually place the connecting plate against the installation position of the bottom frame and then weld it. This requires gradual installation and pressing, which is inefficient and has poor results. Moreover, the position needs to be manually marked on the corresponding position of the bottom frame before welding can be carried out, which is also inefficient and has poor results. Invention content and utility model content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling for splicing fixed connecting plates for chemical pump bases. It eliminates the need to mark the positions where connecting plates need to be installed on the chemical pump base frame. It only requires insertion into the placement groove and placement of the four connecting plates into the corresponding side slots. The tooling automatically presses and positions the connecting plates against the chemical pump base frame, facilitating subsequent manual welding. It greatly reduces the difficulty of manual welding and assembly, and has good processing effect and high efficiency.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A tooling for assembling fixed connecting plates for a chemical pump base includes a bottom wear-resistant fixing plate. A horizontally arranged placement fixing plate is fixed to the top surface of the bottom wear-resistant fixing plate. A placement groove is formed in the middle of the placement fixing plate, and the rear end of the placement groove extends out of the rear wall surface of the placement fixing plate. Side slots extending to the left or right are formed at the front and rear of the left and right side walls of the placement fixing plate. The chemical pump base frame to be processed is placed in the placement groove, and the bottom surface of the chemical pump base frame presses against the top surface of the bottom wear-resistant fixing plate. Four connecting plates are inserted into the corresponding side slots, with their bottom surfaces pressing against the top surface of the bottom wear-resistant fixing plate, and one side wall of the connecting plates pressing against the corresponding side wall of the chemical pump base frame.

[0007] The left and right side walls of the chemical pump base frame are close to the left and right side walls of the placement groove, and the front and rear side walls of the connecting plate are close to the front and rear inner side walls of the corresponding side slots.

[0008] A front fixing plate is fixed to the top surface of the front part of the fixing plate. A screw-in through hole is formed in the middle of the front fixing plate. The screw of the adjusting bolt is screwed into the screw-in through hole. The rear end of the screw of the adjusting bolt extends out of the rear wall of the front fixing plate and is movably connected to the front limiting plate. The bottom surface of the front limiting plate is close to the top surface of the fixing plate. Multiple guide rods are fixed on the front wall of the front limiting plate. The guide rods are inserted into the corresponding guide through holes of the front fixing plate.

[0009] The front part of the screw of the adjusting bolt extends out of the front wall of the front fixing plate and has a rotating part formed therein.

[0010] A collision protection block is fixed on the rear wall of the front limiting plate, and the rear wall of the collision protection block presses against the front wall of the chemical pump base frame.

[0011] The left and right top surfaces of the mounting plate are each fixed with a side fixing plate extending forward and backward. A side clamping cylinder is fixed in the middle of the outer side wall of the side fixing plate. The end of the push rod of the side clamping cylinder extends out of the inner side wall of the corresponding side fixing plate and is fixed with a side pushing plate. The front and rear parts of the inner side wall of the side pushing plate are both fixed with elastic clamping blocks. The lower part of the elastic clamping block is in the corresponding side slot and presses against the outer end of the corresponding connecting plate.

[0012] The outer end of the connecting plate is triangular in shape, and the elastic pressing block has a triangular groove formed on one end of the connecting plate. The outer end of the connecting plate is inserted into the corresponding triangular groove, and the front and rear side walls of the outer end of the connecting plate press against the two corresponding inner side walls of the triangular groove.

[0013] Vertical plates are fixed to the top surfaces of the left and right sides of the bottom wear-resistant fixing plate located behind the fixing plate. A hinge shaft is fixed to the top surface of the bottom wear-resistant fixing plate in front of the vertical plate. A flipping block is movably connected to the hinge shaft via a bearing. A guide wheel frame is fixed to the flipping block. A guide wheel is movably connected to the guide wheel frame via the hinge shaft. The distance between the two guide wheels at their closest points is less than the distance between the left and right sides of the rear end of the placement groove. The two guide wheels at their closest points correspond to the corresponding side wall of the placement groove.

[0014] One end of a return spring is fixed to the middle of the front wall of the vertical plate, and the other end of the return spring is fixed to the guide wheel frame;

[0015] The rear end of the guide wheel frame presses against the anti-collision elastic block fixed on the rear wall of the corresponding vertical plate.

[0016] The outstanding effect of this utility model is:

[0017] Compared with existing technologies, it eliminates the need to mark the locations where connecting plates need to be installed on the chemical pump base frame. It only requires inserting the plate into the placement groove and placing the four connecting plates into the corresponding side slots. The connecting plates will automatically press and position against the chemical pump base frame, facilitating subsequent manual welding. This greatly reduces the difficulty of manual welding and assembly, resulting in better processing effects and higher efficiency. Figure description:

The guide rods 33 are inserted into the corresponding guide through holes of the front fixing plate 30.

[0024] The front part of the screw portion of the adjusting bolt 31 extends out of the front wall of the front fixing plate 30 and has a rotating part formed therein.

[0025] Furthermore, a collision protection block 321 is fixed on the rear wall of the front limiting plate 32, and the rear wall of the collision protection block 321 presses against the front wall of the chemical pump base frame 100.

[0026] Furthermore, a locking nut 34 is screwed onto the screw portion of the adjusting bolt 31, and the rear end face of the locking nut 34 presses against the front wall surface of the front fixing plate 30.

[0027] Furthermore, the left and right top surfaces of the placement fixing plate 20 are both fixed with side fixing plates 40 extending forward and backward. A side pressing cylinder 41 is fixed in the middle of the outer side wall of the side fixing plate 40. The end of the push rod of the side pressing cylinder 41 extends out of the inner side wall of the corresponding side fixing plate 40 and is fixed with a side pushing plate 42. The front and rear parts of the inner side wall of the side pushing plate 42 are both fixed with elastic pressing blocks 43. The lower part of the elastic pressing block 43 is in the corresponding side slot 22 and presses against the outer end of the corresponding connecting plate 200.

[0028] Furthermore, a plurality of outer guide rods 44 are fixed on the outer side wall of the side push plate 42, and the outer guide rods 44 are inserted into guide sleeves fixed in the guide through holes of the corresponding side fixing plates 40.

[0029] Furthermore, the outer end of the connecting plate 200 is triangular in shape, and the elastic pressing block 43 has a triangular groove formed on one end of the connecting plate 200. The outer end of the connecting plate 200 is inserted into the corresponding triangular groove, and the front and rear sidewalls of the outer end of the connecting plate 200 press against the two corresponding inner sidewalls of the triangular groove.

[0030] Furthermore, the top surface of the elastic pressing block 43 at the sharp end of the triangular groove is formed with an extension 431, and the top surface of the outer end of the connecting plate 200 below the extension 431 is close to or in close contact with the bottom surface of the extension 431.

[0031] Furthermore, vertical plates 50 are fixed to the top surfaces of the left and right sides of the bottom wear-resistant fixing plate 10 located behind the fixing plate 20. A hinge shaft is fixed to the top surface of the bottom wear-resistant fixing plate 10 in front of the vertical plate 50. A flipping block 51 is movably connected to the hinge shaft via a bearing. A guide wheel frame 52 is fixed to the flipping block 51. A guide wheel 53 is movably connected to the guide wheel frame 52 via a hinge shaft. The distance between the close ends of the two guide wheels 53 is less than the distance between the left and right sides of the rear end of the placement groove 21. The close ends of the two guide wheels 53 correspond to the corresponding side wall of the placement groove 21.

[0032] One end of the return spring 1 is fixed in the middle of the front wall of the vertical plate 50, and the other end of the return spring 1 is fixed on the guide wheel frame 52.

[0033] The rear end of the guide wheel frame 52 presses against the anti-collision elastic block 2 fixed on the rear wall of the corresponding vertical plate 50.

[0034] In this embodiment, it can be installed at the front end of the conveyor frame. The conveyor frame can be an existing conventional chain conveyor frame or roller conveyor frame, which will not be described in detail here.

[0035] In use, the chemical pump base frame 100 to be processed is placed on the conveyor frame and transported to the rear of the bottom wear-resistant fixing plate 10. Then, it is pushed forward along the two guide wheels 53 by manual labor or a robot. During the push, the elastic deformation of the return spring 1 ensures that the two guide wheels 53 are in close contact with the left and right sides of the chemical pump base frame 100 to guide it, so that the chemical pump base frame 100 can be inserted into the placement groove 21 in a relatively centered manner until its front end presses against the rear wall of the anti-collision block 321. The position of the anti-collision block 321 can be adjusted by loosening the locking nut 34 and rotating the adjusting bolt 31 to change the front and rear position of the anti-collision block 321, thereby changing the position of the chemical pump base frame 100 extending into the placement groove 21 to meet the processing accuracy and make it accurately correspond to the position of the connecting plate 200 that needs to be welded and fixed later (this adjustment is generally only required for the first adjustment in the same batch of products).

[0036] Then, the four connecting plates 200 are inserted into the corresponding side slots 22. The push rods of the two side clamping cylinders 41 push the four elastic clamping blocks 43 to push the connecting plates 200, pressing their end faces against the left and right side walls of the chemical pump base frame 100. When pushing, the front and rear side walls of the outer end of the connecting plate 200 press against the two corresponding inner side walls of the triangular groove. The top surface of the outer end of the connecting plate 200 is close to or in close contact with the bottom surface of the extension 431, which can prevent the connecting plate 200 from detaching from the elastic clamping blocks 43 when pressed.

[0037] After assembly, the four connecting plates 200 can be manually welded to the left or right side wall of the chemical pump base frame 100. The process is convenient, the welding position is accurate, and the performance is good.

[0038] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
