Description

Technical Field

[0001] The utility model relates to the technical field of non-standard equipment, in particular to a pump body turning tool. Background Art

[0002] The pump body refers to the main part of the water pump, which is the core component for transporting fluid to the required location. The pump body is usually composed of parts such as the body, inlet and outlet flanges, bearing seats and sealing seats. Among them, the inlet and outlet flanges are used to connect the inlet and outlet pipes, the bearing seats are used to support the shaft components, and the sealing seats are used to ensure the sealing performance of the pump body. During assembly, because the pump body is heavy and the various components need to be installed in different directions on the body, in order to facilitate assembly by operators and improve assembly efficiency, the assembly line often adopts the method of turning the pump body while the operator remains in the same position. The existing pump body turning is mostly achieved by a positioner, but the positioner is driven by a motor. The procurement cost of an integrated positioner is high, which increases the production cost. Therefore, it is necessary to design a special pump body turning tool. Utility Model Content

[0012] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0015] like Figure 1As shown, the pump body turning tooling includes a hanger 1, a rocking assembly 2, an expander 3, and a driver 4. The hanger 1 includes a crossbeam 11 and a hanger 12. The hanger 12 is vertically connected to the middle of the crossbeam 11. Two sets of driver 4 are mounted in mirror symmetry at the upper end of the crossbeam 11, with the output ends of the two sets of driver 4 facing away from each other. The lower end of the crossbeam 11 is provided with a slide rail 111. The two sets of rocking assemblies 2 are movably connected to the slide rails 111 in a one-to-one correspondence. The output ends of the driver 4 are connected to the fixed ends of the rocking assembly 2, driving the rocking assembly 2 to perform reciprocating linear motion along the slide rails 111. The expander 3 is mounted on the inner side of the movable end of the rocking assembly 2 and is arranged facing each other. Specifically, in this embodiment, the hanger 1 is hoisted in a workshop, specifically connected to the workshop beam via the hanger 12. The crossbeam 11 is mounted below the hanger 12 and is used to be vertically connected to the lower end of the hanger 12 for mounting the driver 4 and the rocking assembly 2. Among them, the driving member 4 and the rotary assembly 2 are arranged in a one-to-one correspondence. The two groups of driving members 4 are used to drive the two groups of rotary assemblies 2 to move back and forth along the slide rail 111, adjust the distance between the two groups of rotary assemblies 2, and facilitate the lifting and assembly of the workpiece (not shown in the figure) between the two groups of rotary assemblies 2, and adapt to workpieces of different lengths. When in use, first use the lifting tool to transport the workpiece to the bottom of the flipping tool and lift it to a certain height. The driving member 4 drives the rotary assembly 2 to move toward each other, clamp the workpiece, and insert the tensioner 3 into the holes at both ends of the workpiece. The tensioner 3 tightens the workpiece to avoid slipping when flipping the workpiece, resulting in the workpiece not being able to follow the output end of the rotary assembly 2 and rotate at the same angle. The tooling structure we designed is extremely simple in structure and does not require an external positioner to flip the workpiece, which greatly reduces the cost of using tooling equipment and reduces the assembly cost of the product.

[0016] like Figure 1 As shown, a safety rope 112 is provided at the lower end of the beam 11. Specifically, after the workpiece is assembled, the lower end of the safety rope 112 is connected to the workpiece as a redundant protection to prevent the workpiece from falling.

[0017] like Figure 1As shown, the swing assembly 2 includes a slider 21, a fixed plate 22, a mounting frame 23, a first cylinder 24 and a diverter 25. The slider 21 is movably connected to the slide rail 111, the lower end of the fixed plate 22 is connected to the slider 21, the upper end of the fixed plate 22 is movably connected to the output end of the driving member 4, the upper end of the mounting frame 23 is connected to the slider 21, the lower end of the mounting frame 23 is connected to the diverter 25, the fixed end of the first cylinder 24 is movably connected to the mounting frame 23, the output end of the first cylinder 24 is connected to the input end of the diverter 25, and the expander 3 is installed on the output end of the diverter 25. Specifically, in this embodiment, the output end of the driving member 4 is movably connected to the upper end of the fixed plate 22, and then the slider 21 can be driven to move along the slide rail 111 through the fixed plate 22. The upper end of the mounting frame 23 is connected to the slider 21 and can follow the displacement. The first cylinder 24 is inverted on the mounting frame 23, and the fixed end of the first cylinder 24 is movably installed, so that when the output end of the first cylinder 24 is extended or retracted, it can follow the steering gear 25 to rotate slightly. The entire layout uses the first cylinder 24 as the power source, without a motor, single power, simple layout, and reduced tooling costs.

[0018] like Figures 1-2 As shown, the steering gear 25 comprises a housing 251, sector teeth 252, and a driven gear 253. The sector teeth 252 and driven gear 253 are movably mounted within the housing 251 via a rotating shaft. The sector teeth 252 mesh with the driven gear 253. A connecting rod 2521 is provided on the surface of the sector teeth 252. The connecting rod 2521 extends through an arcuate slot 2511 in the housing 251 and connects to the output end of the first cylinder 24. The expander 3 is connected to the rotating shaft of the driven gear 253. Specifically, in this embodiment, when the output end of the first cylinder 24 is extended or retracted, it drives the sector teeth 252 to rotate. Because the fixed end of the first cylinder 24 is movably connected to the mounting bracket 23, the output end of the first cylinder 24 can oscillate slightly during extension or retraction. The connecting rod 2521 extends through the arcuate slot 2511, limiting the oscillation trajectory and displacement of the sector teeth 252. As the sector teeth 252 rotate, the driven gear 253 is driven to rotate. Since the rotating shafts for installing the sector teeth 252 and the driven gear 253 are movably connected to the housing 251 through bearings, the rotating shaft for installing the driven gear 253 rotates synchronously, thereby driving the expander 3 to rotate. At this time, the expander 3 is inserted into the hole of the workpiece and expands, thereby driving the workpiece to flip, thereby completing the adjustment of the workpiece orientation.

[0019] Specifically, the driving member 4 is a second cylinder. Avoiding the use of electric drives such as screw rods or electric push rods, the full pneumatic layout only requires air pipelines when designing the workshop, without the need to lay power harnesses, thus reducing tooling costs.

[0020] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
