Description

Technical Field

[0001] This technical solution relates to the field of pump assembly equipment technology, specifically to a riveting and tooling recycling device and pump assembly equipment having the device. Background Technology

[0002] Pumps, as the core power equipment for fluid transportation, are widely used in industrial production, agricultural irrigation, and domestic water supply. Their assembly precision directly determines their operational stability and service life.

[0003] In existing technologies, the assembly of pump bodies such as gear pumps and self-priming pumps mostly relies on manual or semi-automatic equipment to be completed step by step, which has the following shortcomings:

[0004] 1. Poor connection stability and low assembly efficiency between impeller and pump shaft: In traditional assembly processes, impeller and pump shaft are often connected by interference fit or bolt fastening. The former relies on manual hammering and pressing, which can easily lead to problems such as excessive or insufficient clearance, causing the impeller and pump shaft to move relative to each other when the pump is running, affecting fluid delivery efficiency. The latter requires additional fasteners such as bolts and nuts, which increases the cost of parts and assembly processes. Moreover, after long-term use, the bolts are prone to loosening, posing a risk of impeller falling off.

[0005] 2. Low assembly efficiency and poor consistency of water injection screws: The assembly of water injection screws on the pump head is mostly done manually. The uneven force of manual operation can easily lead to insufficient or excessive tightening torque. Insufficient torque will cause water leakage at the water injection port when the pump is working, while over-tightening will cause the screw to strip or damage the pump head threads. At the same time, manual assembly requires one by one to align the water injection port with the screw threads, which is slow and has low production efficiency.

[0006] 3. Low installation efficiency of pump head and pump body: The assembly of pump head and pump body usually involves manually placing the pump head on the pump body, and then manually passing the connecting screw through the pump head and tightening it on the pump body. Manual assembly is inefficient, time-consuming and labor-intensive. Summary of the Invention

[0019] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0020] 1. This technical solution applies pressure to the riveting fixture placed on the pump body through a riveting mechanism, driving the riveting fixture to rivet the connection between the impeller and the pump shaft, thus achieving a tight connection between the impeller and the pump shaft. Mechanized assembly improves production efficiency and the assembly consistency of the impeller and pump shaft, avoiding riveting deviations caused by uneven manual force application, and ensuring the tightness of the connection between the impeller and the pump shaft. After the riveting operation is completed, the riveting mechanism can automatically remove the riveting fixture from the pump body, and the fixture recycling mechanism can complete the recycling of the riveting fixture, thereby facilitating the subsequent recycling and reuse of the riveting fixture, eliminating the steps of manual disassembly and sorting of the riveting fixture, saving time and effort. By setting an electromagnet to attract the riveting fixture to achieve the separation of the riveting fixture from the pump body, the time-consuming and labor-intensive problem of manually removing the riveting fixture from the pump body is avoided.

[0021] 2. This technical solution uses a positioning groove at the lower end of the riveting fixture. The positioning groove contains an impeller positioning rod and a punch rod. By utilizing the fit between the positioning groove and the outside of the impeller and the upper end of the pump body, as well as the precise insertion of the impeller positioning rod into the impeller positioning hole, dual positioning of the impeller is achieved, ensuring the coaxiality of the impeller and pump shaft during riveting. The punch rod punches a hole at a preset position on the impeller, causing the inner wall of the shaft hole connecting the impeller and pump shaft to bulge and deform towards the center, tightly pressing against the outer wall of the pump shaft, forming a riveting structure. This structurally ensures the stability of the connection between the pump shaft and the impeller, preventing the impeller from falling off. Simultaneously, an observation port allows for easy manual observation to ensure the impeller positioning accuracy by verifying that the impeller positioning rod is accurately inserted into the impeller positioning hole.

[0022] 3. This technical solution incorporates a screw-loading device, which includes a screw feeding mechanism, a screw-loading mechanism, and a pump head stop mechanism. The screw feeding mechanism sorts and conveys the water-injection screws, replacing manual material handling and improving feeding efficiency, thus avoiding omissions and mis-loading during manual feeding. The screw-loading mechanism picks up the water-injection screws conveyed by the feeding mechanism and tightens them into the water inlet of the pump head on the pump head holder. Standardized torque control ensures consistent tightening torque for each screw, resolving quality issues such as leakage and stripping caused by uneven tightening force during manual tightening. During tightening, the pump head stop mechanism presses and fixes the pump head onto the pump head holder, preventing rotation and displacement of the pump head during tightening, ensuring alignment accuracy between the water-injection screw and the water inlet, and improving assembly stability. The overall design improves assembly efficiency and product consistency, reduces manual labor intensity, and is suitable for large-scale production needs.

[0023] 4. This technical solution uses a pump body positioning mechanism to position and clamp the pump body on the pump body placement seat, ensuring the positional stability of the pump body during the assembly process and avoiding subsequent docking accuracy deviations due to pump body offset. At the same time, the pump head shifting and pressing mechanism completes the picking, shifting, and pressing operations of the pump head, pressing the pump head onto the upper end of the pump body, realizing automated docking assembly of the pump head and pump body, improving the docking efficiency of the pump head and pump body, and ensuring the coaxiality and end face fit of the two, avoiding the problem of difficulty in controlling docking accuracy by manual operation. In addition, it eliminates the steps of manual transfer and positioning of the pump head, reducing the intensity of manual operation and improving production efficiency. Attached Figure Description

[0041] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0042] Combination Figure 1 and Figure 3A riveting and tooling recycling device includes: a mounting frame 31; a riveting mechanism 32 mounted on the mounting frame 31, the riveting mechanism 32 being used to press and remove a riveting tool 33 located at the upper end of a pump body 100; a riveting tool 33 detachably connected to the riveting mechanism 32, the riveting tool 33 being placed at the upper end of the pump body 100 manually or by a robotic arm, the riveting tool 33 being able to rivet the connection between the impeller 102 and the pump shaft 103 of the pump body 100 under the drive of the riveting mechanism 32; and a tooling recycling mechanism 34 mounted on the mounting frame 31. 4 is used to recycle the riveting fixture 33 located on the riveting mechanism 32; by first placing the riveting fixture 33 on the upper end of the pump body 100, and then pressing down the riveting fixture 33, the riveting fixture 33 rivets the connection between the impeller 102 and the pump shaft 103. After riveting, the riveting mechanism 32 drives the riveting fixture 33 to move upward and away from the pump body 100. Then the fixture recycling mechanism 34 moves to the bottom of the riveting fixture 33 to catch the riveting fixture 33 and recycle it to the set position, so that the riveting fixture 33 can be placed on the pump body 100 to be processed later.

[0043] Combination Figure 4 and Figure 5 The lower end of the riveting fixture 33 is provided with several impeller positioning rods 333 and at least one punch rod 334. This design provides two impeller positioning rods 333 and four punch rods 334. The impeller 102 has several positioning holes 107. After the riveting fixture 33 is placed on the pump body 100, the impeller positioning rods 333 are inserted into the corresponding positioning holes 107 to position the impeller 102 and ensure that the punch rods 334 press down to punch the hole accurately. The impeller 102 has a shaft hole, and the pump shaft 103 passes through and is connected in the shaft hole. The punch rods 334 press down to punch the edge of the shaft hole, thereby causing the inner wall of the shaft hole to deform inward and bulge to abut against the pump shaft 103, thus ensuring the stable connection between the impeller 102 and the pump shaft 103.

[0044] Combination Figure 4 and Figure 5 The lower end of the riveting fixture 33 is provided with a positioning groove 331. The bottom of the positioning groove 331 is provided with an impeller positioning rod 333 and a punch rod 334. After the riveting fixture 33 is placed on the upper end of the pump body 100, the impeller 102 and the boss 108 on the upper end of the pump body 100 can be placed in the positioning groove 331, thereby ensuring that the riveting fixture 33 is placed accurately, thus ensuring the coaxiality and accuracy of the impeller 102 and the pump shaft 103 after riveting.

[0045] Combination Figure 4 and Figure 5The side wall of the positioning groove 331 is provided with an observation port 332, which connects the inside of the positioning groove 331 with the outside. Through the observation port 332, the impeller positioning rod 333 and the punch rod 334 can be observed, thus ensuring that the impeller positioning rod 333 can be accurately inserted into the corresponding positioning hole 107.

[0046] Combination Figure 4 and Figure 5 A washer 335 is provided at the lower edge of the riveting fixture 33. The washer 335 is movably pressed against the upper end of the pump body 100 to prevent damage to the pump body 100 when the riveting fixture 33 is pressed down.

[0047] like Figure 3 The riveting mechanism 32 includes: a lifting drive component 321, which is an electric cylinder, pneumatic cylinder, or electric push rod, and is mounted on a mounting frame 31; a lifting plate 322, which is vertically slidably mounted on the mounting frame 31 via a guide rod, and the lifting plate 322 is connected to the drive end of the lifting drive component 321; a pressing part 323, which is mounted on the lower end of the lifting plate 322, and the pressing part 323 is used to movably abut against the upper end of the riveting fixture 33; and an electromagnet 324, which is mounted inside the pressing part 323, and the electromagnet 324 is used to hold the riveting fixture 33; the lifting plate 322 is driven by the lifting drive component 321. 22 descends, causing the pressing part 323 to press against the upper end of the riveting fixture 33 and causing the punch 334 to move down to punch holes, thus achieving the riveting between the impeller 102 and the pump shaft 103. Subsequently, the electromagnet 324 is energized to magnetically attract the riveting fixture 33, and the lifting plate 322 moves up, causing the riveting fixture 33 to detach from the pump body 100, thus removing the riveting fixture 33. The riveting fixture 33 is made of soft magnetic material. The riveting fixture 33 can only be attracted by the electromagnet and cannot actively attract ferromagnetic objects on its own. The riveting fixture 33 is made of materials such as iron-silicon-aluminum alloy, iron-nickel soft magnetic alloy, soft magnetic ferrite, and low carbon steel.

[0048] like Figure 3The tooling recycling mechanism 34 includes: a mounting plate 341, which is inclinedly mounted on the mounting frame 31; a receiving seat 342, which is slidably mounted on the mounting plate 341 via a slide rail and a slider, and the upper end of the receiving seat 342 is provided with a receiving groove 3421 for receiving the riveting tooling 33 removed by the riveting mechanism 32; and a sliding drive component 343, which is a linear motor, cylinder, or electric push rod, mounted on the mounting plate 341, and the drive end of the sliding drive component 343 is connected to the receiving seat 341. 42. The sliding drive 343 is used to drive the receiving seat 342 to move below the pressing part 323 of the riveting mechanism 32. After the receiving seat 342 is located below the pressing part 323, the electromagnet 324 is de-energized, and the riveting fixture 33 falls into the receiving groove 3421 by its own weight. Then the sliding drive 343 drives the riveting fixture 33 to move to the set position, so that it can be easily picked up by a robot or a person and placed on the pump body 100 to be processed later, thereby realizing the cyclic use of the riveting fixture 33.

When the screw-loading mechanism 42 is performing screw-tightening operations, the pump head stop mechanism 44 is used to press against the upper end of the pump head 101 in the pump head placement seat 23 to prevent the pump head 101 from moving.

[0052] Combination Figure 7 and Figure 8 The screw feeding mechanism 41 includes: a vibratory feeder 411, which is disposed on the side of the frame 1, and the vibratory feeder 411 is used to store the water-filled screws 104; a feeding guide rail 412, which is connected to the discharge port of the vibratory feeder 411, and the vibratory feeder 411 and the feeding guide rail 412 transport the water-filled screws 104 sequentially to the material distribution component 413; and a material distribution component 413, which is installed at the discharge end of the feeding guide rail 412, and is used to remove the water-filled screws 104.

The material distribution notch 4151 is used to receive the water injection screw 104 sent from the discharge end of the feeding guide rail 412. The material distribution notch 4151 has a protruding edge inside, which abuts against the lower end of the head of the water injection screw 104, and the rod of the water injection screw 104 can extend out of the lower end of the material distribution notch 4151; and a baffle plate 416, which is mounted on the frame 1 and located beside the discharge end of the feeding guide rail 412, and the baffle plate 416 is located beside the material distribution plate 415. The material distribution plate 415 moves along the baffle plate 416. The material guide 414 moves along the feed guide 412. The baffle plate 416 is used to restrict the water-filled screw 104 from disengaging from the material distribution notch 4151. The ejector drive 417, which is a cylinder, is mounted on the frame 1 and its drive end can be movably placed inside the material distribution notch 4151. The ejector drive 417 is used to eject the water-filled screw 104 located inside the material distribution notch 4151.
