Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, the present invention provides a worm gear riveting device for a pump, comprising a body 1, a fixing module 2 and a riveting module 3 both disposed on the body 1, the fixing module 2 being used to fix the product 4 to be riveted, and the riveting module 3 being used to rivet the product 4 on the fixing module 2. The riveting module 3 includes an electric cylinder 31, a riveting component 32 and a guide assembly 33. The guide assembly 33 and the electric cylinder 31 are both installed on the body 1, the riveting component 32 is movably disposed on the guide assembly 33, and the electric cylinder 31 drives and connects to the riveting component 32.

[0021] During operation, the worker places product 4 (i.e., the worm gear and gear that have been preliminarily installed) into the machine body 1 and fixes it with the fixing module 2 so that product 4 is located directly below the riveting module 3. Then the riveting module 3 is activated, and the electric cylinder 31 controls the riveting part 32 to descend along the guide component 33 until it presses down on product 4 and rivets it a certain distance. Then the electric cylinder 31 controls the riveting part 32 to rise, and the worker can then remove it and replace it with the next product 4, thus completing the cycle processing.

[0022] Compared to the existing technology that uses a cylinder to control the lifting of the riveting part 32, this utility model uses an electric cylinder 31 for control, which has higher precision and more stable riveting force than a cylinder, thus helping to improve the yield of product 4.

[0023] In this embodiment, the riveting component 32 is equipped with a pressure sensor 34, which is used to sense the pressure between the riveting component 32 and the product 4. That is, when riveting, if the product 4 is unqualified, the pressure applied by the product 4 to the riveting component 32 will be different when the riveting component 32 moves to the forming end after contacting the product 4 again: if the gear of the product 4 cannot be riveted to the specific position of the worm gear, resulting in a riveting depth less than expected, the pressure applied by the gear to the riveting component 32 will increase; if the product 4 is not riveted in place, the pressure applied to the riveting component 32 will decrease. Through the above determination, qualified and unqualified products 4 can be reliably distinguished. The sensing result of the pressure sensor 34 will be transmitted to the host computer (not shown in the figure) of the machine body 1, so that the staff can obtain information on whether the product 4 is qualified in a timely manner, so as to classify the product 4 after riveting, and further ensure the yield of the product 4.

[0024] In this embodiment, the electric cylinder 31 includes a motor 35, a gear transmission assembly 36, and a lead screw 37. The motor 35 drives the lead screw 37 through the gear transmission assembly 36, and the riveting component 32 is installed at the end of the lead screw 37. By driving the gear transmission assembly 36 to rotate, the lead screw 37 moves up and down relative to the gear transmission assembly 36, thereby driving the riveting component 32 to move up and down, achieving the riveting effect.

[0025] Specifically, the body 1 is provided with a top plate 11, and the motor 35 and gear transmission assembly 36 are both located above the top plate 11; the top plate 11 is provided with a clearance hole 12, and the lead screw 37 passes through the clearance hole 12 and protrudes to the bottom of the top plate 11; the riveting part 32 and the fixing module 2 are both located below the top plate 11.

[0026] The width of the rivet 32 ​​is greater than the width of the clearance hole 12.

[0027] The top plate 11 supports the motor 35 and gear transmission assembly 36, making the present invention clearly divided into upper and lower layers. Workers only need to operate the lower fixed module 2, ensuring safety.

[0028] In this embodiment, the fixing module 2 includes at least two pressing components 20, which are used to press the product 4 to be riveted onto the machine body 1.

[0029] In actual use, the pressing assembly 20 includes a pressing member 21 and a fixing nail 22. One end of the pressing member 21 is movably disposed on the body 1, and the other end of the pressing member 21 is used to press the product 4 to be riveted. The body 1 is provided with a plurality of positioning holes 13. The fixing nail 22 passes through the pressing member 21 and is inserted into one of the positioning holes 13.

[0030] One end of the clamping member 21 can be mounted to the machine body 1 by a screw 24, and the other end can rotate around the screw 24, thereby adjusting the posture of the clamping member 21 according to the specifications of the product 4. After adjustment, it is as follows: Figure 1 The product 4 is held in place by pressing it down, and the fixing pin 22 is inserted into the corresponding positioning hole 13 to achieve the pressing effect. When it is necessary to replace the product 4, the pressing part 21 can be released from the product 4 by simply lifting it up with the fixing pin 22 so that the product 4 can be replaced.

[0031] It should be noted that the fixing pin 22 is preferably a screw, and the positioning hole 13 is a screw hole. The fixing pin 22 is screwed into the positioning hole 13 to ensure reliable pressing of the product 4. After riveting is completed, simply loosen the screw 24 to allow the pressing part 21 to stop pressing the product 4.

[0032] Specifically, the holding member 21 is provided with an adjustment groove 23. The fixing nail 22 passes through the adjustment groove 23 and is inserted into one of the positioning holes 13, so that after adjusting the position of the holding member 21, the fixing nail 22 can slide in the adjustment groove 23 to correspond to the position of the positioning hole 13.

[0033] In this embodiment, the body 1 is equipped with a foolproof module 14, which is used to sense whether a person's hand has left the body 1. The foolproof module 14 can be an infrared transceiver, photoelectric switch, etc., and is used to sense whether a person's hand has entered the body 1. The riveting module 3 will only activate when the person's hand is not inside the body 1, thus ensuring safety.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
