Description

Technical Field

[0001] This utility model relates to the field of press riveting technology, specifically a press riveting connection device for a hand pump cover. Background Technology

[0002] For the operation of riveting the hand pump cover, it is usually necessary to manually place the rivet block structure onto the rivet block tray, then align the position of the hand pump cover to be riveted with the rivet block tray, and then cooperate with the relevant actions of the riveting machine to achieve the riveting of the hand pump cover at that position. In the process of manually placing the rivet block, it is difficult to maintain the same force, position and accuracy when placing it manually, which results in a long time for each placement, thus affecting the riveting efficiency when riveting multiple hand pump covers. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a riveting connection device for a hand pump cover, so as to solve the problem of low efficiency of manual riveting block placement when riveting multiple quantities as mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a riveting connection device for a hand pump cover, comprising a riveting machine body, a material guiding mechanism installed on the riveting machine body, a plurality of linearly arranged rivet block structures placed inside the material guiding mechanism, and an extrusion assembly installed on the material guiding mechanism;

[0005] The riveting machine body includes a riveting block tray;

[0006] The material guiding mechanism includes a support frame located on one side of the rivet block tray. A material unloading position is installed on the side of the support frame near the rivet block tray. Guide grooves are provided on both the front and back of the support frame. An intermittently operating pushing structure is installed on the support frame to push several rivet block structures to the material unloading position in sequence. A transverse moving component is installed between the bottom of the support frame and the riveting machine body.

[0007] Preferably, the unloading position is arranged in a U-shape, and when the transverse component is running, the unloading position is adjusted to the top of the rivet tray.

[0008] Preferably, the extrusion assembly includes a bracket installed on the front of the unloading position, an electric push rod mounted on the bracket, a pressure plate mounted on the free end of the electric push rod, and the center of the rivet block structure within the unloading position is coaxial with the center of the pressure plate.

[0009] Preferably, the riveting machine body also includes a base, a hydraulic module is installed on the top of the base, a through groove is opened on the hydraulic module, and the riveting block tray is located on the bottom wall of the through groove.

[0010] Preferably, the lateral movement assembly includes an electric telescopic rod and a connecting plate mounted on the top surface of the base, with the free end of the electric telescopic rod connected to the connecting plate.

[0011] Preferably, two support rods are installed between the top of the connecting plate and the bottom of the bearing frame. When the electric telescopic rod extends outward, it adjusts the rivet block structure in the unloading position so that its center is coaxial with the center of the rivet block tray.

[0012] Preferably, the pushing structure consists of a micro motor, a bidirectional lead screw, and a push plate, with the push plate sleeved on the bidirectional lead screw and passing through the bearing frame along the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model controls the positional relationship between the bearing frame, the material feeding position and the rivet tray by using a transverse component to control the positional relationship between them. It also works with a pushing component to intermittently push the rivet structure in the bearing frame, pushing a single rivet structure into the material feeding position at a time. When the rivet structure inside the material feeding position above the rivet tray falls down, it will directly enter the positioning groove at the top of the rivet tray, thus completing the feeding operation.

[0015] 2. After the material unloading position is adjusted to be directly above the rivet tray, the electric push rod drives the pressure plate to press the rivet structure in the material unloading position downward, which can ensure that it is accurately placed into the positioning groove on the rivet tray.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model proposes a riveting connection device for a hand pump cover, including a riveting machine body 1, which includes a rivet block tray 101. A guiding mechanism 2 is installed on the riveting machine body 1, and a plurality of rivet block structures 3 arranged linearly are placed inside the guiding mechanism 2. An extrusion component 4 is installed on the guiding mechanism 2. The purpose is to guide the rivet block structures 3 into the rivet block tray 101 during each riveting interval of the hand pump cover by the guiding mechanism 2. After a single riveting of the hand pump cover is completed, it needs to be moved away from the rivet block tray 101 to provide the guiding mechanism 2 with the space required to guide the rivet block structures 3 into the rivet block tray 101.

[0023] Specifically, the material guiding mechanism 2 includes a support frame 201 located on one side of the rivet tray 101. A discharge position 202 is installed on the side of the support frame 201 closest to the rivet tray 101. The discharge position 202 is U-shaped. When the transverse component 204 operates, it adjusts the discharge position 202 to the top of the rivet tray 101, and the internal front-to-back gap of the discharge position 202 is consistent with the outer diameter of the rivet structure 3. Furthermore, when a rivet structure 3 enters the range of the discharge position 202, and its side coincides with the opening of the discharge position 202, the other surface of the rivet structure 3 is in contact with the inner wall of the discharge position 202. Guide grooves 2011 are provided on both the front and back of the support frame 201. An intermittently operating pushing structure 203 is installed on the support frame 201 to sequentially push several rivet structures 3 to the discharge position 202. A transverse component 204 is installed between the bottom of the support frame 201 and the riveting machine body 1. In practical applications, several rivet structures 3 are placed one by one into the support frame 201. Then, by operating the transverse component 204, the support frame 201 and its related structures above it are moved a set distance toward the rivet tray 101, so that the unloading position 202 after the movement is directly above the rivet tray 101. Then, in conjunction with the operation of the push structure 203, several rivet structures 3 are pushed along the internal path of the support frame 201 toward the unloading position 202, with each push distance matching the outer diameter of the rivet structure 3. The center of the rivet structure 3 entering the unloading position 202 is aligned vertically with the center of the rivet tray 101, ensuring that the rivet structure 3 falling from the unloading position 202 directly enters the positioning groove at the top of the rivet tray 101, thus completing the feeding operation. Furthermore, after a single feeding, the transverse component 204 is operated again to move the carrier frame 201 back to its original position, reserving sufficient operating space for the subsequent riveting of the hand pump cover.

[0024] Following the above, the rivet structure 3 entering the unloading position 202 may fail to fall down on its own. To effectively solve this problem, such as... Figure 3 and Figure 4 As shown, the extrusion assembly 4 includes a bracket 401 installed on the front of the unloading position 202. An electric push rod 402 is mounted on the bracket 401, and a pressure plate 403 is installed on the free end of the electric push rod 402. The center of the rivet structure 3 in the unloading position 202 is coaxial with the center of the pressure plate 403. After the unloading position 202 moves directly above the rivet tray 101, the electric push rod 402 is operated to extend downward accordingly. This causes the pressure plate 403 to exert a downward extrusion force on the rivet structure 3 in the unloading position 202, causing the rivet structure 3 to fall vertically into the positioning groove in the rivet tray 101, thus achieving accurate placement of the rivet structure 3.

[0025] like Figure 1As shown, the riveting machine body 1 also includes a base 102, and a hydraulic module 103 is installed on the top of the base 102. A through groove is opened on the hydraulic module 103, and the riveting block tray 101 is located on the bottom wall of the through groove. The riveting machine body 1 is existing technology and is designed to realize the riveting operation of the hand pump cover, so its operating principle and related functions will not be described in detail here.

[0026] The transverse assembly 204 includes an electric telescopic rod 2041 and a connecting plate 2042 installed on the top surface of the base 102. The free end of the electric telescopic rod 2041 is connected to the connecting plate 2042. Two support rods 2043 are installed between the top of the connecting plate 2042 and the bottom of the support frame 201. By lifting the support rods 2043, the support frame 201 is lifted to a position where the bottom is at the same height as the top of the rivet tray 101. The extension direction of the central axis of the support frame 201 intersects with the center of the rivet tray 101, ensuring that when the electric telescopic rod 2041 extends outward, the rivet structure 3 in the unloading position 202 is adjusted to a state where the center of the rivet structure 3 is coaxial with the center of the rivet tray 101.

[0027] The pushing structure 203 consists of a micro motor 2031, a bidirectional lead screw 2032, and a push plate 2033. The push plate 2033 is sleeved on the bidirectional lead screw 2032, and its guide groove 2011 passes through the support frame 201. This combination of the micro motor 2031, bidirectional lead screw 2032, and push plate 2033 is existing technology. Its purpose is to control the push plate 2033 to move laterally along the path of the support frame 201 when the micro motor 2031 drives the bidirectional lead screw 2032 to rotate, thereby pushing the rivet structure 3. One side of the push plate 2033 has an arc-shaped groove that fits the outer wall of the rivet structure 3, increasing the contact area and improving stability during pushing.
