Description

Technical Field

[0001] This utility model relates to the field of product assembly technology, and in particular to an integrated device for pressing and expanding a spring and base. Background Technology

[0002] In the production process of spring base assemblies, the pressing of the spring to the base and the expansion of the spring are crucial steps. To avoid the risk of a single point of failure causing a complete production line shutdown, traditional processing methods typically separate the pressing and expansion processes, using two separate sets of equipment. Separating the equipment allows for risk diversification. For example, the spring pressing equipment and spring pin pressing system with patent number CN115816055A can only press the spring. If the pressing equipment fails, the expansion equipment can continue processing the previously pressed inventory components, avoiding a complete shutdown. However, separating the pressing and expansion processes on different equipment increases the number of production steps and makes the process more cumbersome, resulting in lower production efficiency.

[0003] Therefore, the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an integrated device for pressing and expanding the spring and base, which aims to solve the problem that when the pressing of the spring and base and the expansion of the spring are carried out separately on different devices, the production process becomes more complicated and the production efficiency is not high.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: In a first aspect, embodiments of this utility model provide an integrated device for pressing and expanding a spring sheet and a base, comprising: frame; The carrier is disposed within the frame, and the top side of the carrier is provided with a receiving groove for loading the base and the spring clips; A first lifting mechanism is disposed within the frame; A pressing column is mounted on the first lifting mechanism and is driven to move up and down by the first lifting mechanism. The bottom end of the pressing column faces the receiving groove and is used to push the spring piece and the base to complete the pressing. A second lifting mechanism is installed inside the frame; An expansion rod is mounted on the second lifting mechanism and is driven to move up and down by the second lifting mechanism. The bottom end of the expansion rod faces the receiving groove and is used to squeeze the inner sidewall of the spring to complete the expansion.

[0006] Furthermore, the expansion rods are provided in multiple forms, each of which is respectively mounted on the second lifting mechanism. The bottom end of each expansion rod faces the receiving groove, and the multiple expansion rods surround the pressing column to form a circle.

[0007] Furthermore, the outer side of the pressing column is provided with multiple vertically opened guide grooves, and each of the outward expansion rods is slidably disposed in each of the guide grooves and corresponds to it one by one.

[0008] Furthermore, in the integrated pressing and expanding device for the spring sheet and base, the first lifting mechanism includes: The first cylinder is fixedly installed inside the frame; A first piston rod, one end of which is connected to and driven by the first cylinder; A first connecting plate is connected to the other end of the first piston rod, the top end of the pressing column is connected to the bottom side of the first connecting plate, and the outward expansion rod passes through the first connecting plate.

[0009] Furthermore, in the integrated pressing and expanding device for the spring sheet and base, the second lifting mechanism includes: The second cylinder is fixedly installed inside the frame; The second piston rod, one end of which is connected to and driven by the second cylinder; The second connecting plate is connected to the other end of the second piston rod, and the top end of the outward expansion rod is connected to the bottom side of the second connecting plate. The second connecting plate is located above the first connecting plate.

[0010] Furthermore, in the integrated pressing and expanding device for the spring sheet and base, the second lifting mechanism further includes: The third connecting plate has a socket and is detachably mounted on the bottom side of the second connecting plate. The top end of the expansion rod is located in the socket and connected to the third connecting plate.

[0011] Furthermore, the bottom end of the expanding rod has a protrusion on the side close to the spring piece, and an inclined surface is provided between the protrusion and the bottom end face of the expanding rod.

[0012] Furthermore, the integrated pressing and expanding device for the spring sheet and base also includes: A control console is located at the bottom of the rack; A start / stop button is located on the outside of the control panel and is electrically connected to the control panel.

[0013] Furthermore, the integrated pressing and expanding device for the spring sheet and base also includes: A sensor is installed inside the first cylinder and electrically connected to the control console. When the sensor detects that the pressing column has completed the pressing operation, the second lifting mechanism drives the outward expansion rod to move downward to expand the inner wall of the spring sheet.

[0014] Furthermore, the integrated pressing and expanding device for the spring sheet and base also includes: A power switch, wherein the power switch is disposed on the outside of the console and electrically connected to the console; A pause button is located on the outside of the console and is electrically connected to the console.

[0015] Compared with the prior art, the embodiments of this utility model have the following advantages: In this invention, the first lifting mechanism drives the pressing column to press down the spring sheet, allowing it to engage with the base.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Example: Please see Figures 1-9 The integrated pressing and expanding device for the spring piece 12 and the base 13 includes: a frame 1; a carrier 2, which is disposed within the frame 1 and has a receiving groove 201 on its top side for loading the base 13 and the spring piece 12; a first lifting mechanism 3, which is disposed within the frame 1; a pressing column 4, which is disposed on the first lifting mechanism 3 and is driven to move up and down by the first lifting mechanism 3, with the bottom end of the pressing column 4 facing the receiving groove 201, for pushing the spring piece 12 and the base 13 to complete the pressing; a second lifting mechanism 5, which is disposed within the frame 1; and an expanding rod 6, which is disposed on the second lifting mechanism 5 and is driven to move up and down by the second lifting mechanism 5, with the bottom end of the expanding rod 6 facing the receiving groove 201, for squeezing the inner wall of the spring piece 12 to expand the spring piece 12 outward.

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, the integrated pressing and expanding device for the spring piece 12 and the base 13 includes a frame 1, a carrier 2, a first lifting mechanism 3, a pressing column 4, a second lifting mechanism 5, and an expanding rod 6; wherein, the carrier 2 is fixedly installed in the frame 1, and the top side of the carrier 2 is provided with a receiving groove 201 for loading and fixing the base 13 and the spring piece 12. The structure of the spring piece 12 is detailed in [the diagram]. Figure 8 For details of the assembly structure of the base 13 and the spring 12, please refer to [link / reference]. Figure 9The first lifting mechanism 3 is installed inside the frame 1 to drive the pressing column 4 to move up and down. During the descent, the bottom end of the pressing column 4 presses down on the spring piece 12, so that the triangular protrusion 601 on the side of the spring piece 12 can engage with the latch on the side of the base 13. During the pressing process, the side of the spring piece 12 is squeezed and deformed inward. Therefore, after the spring piece 12 and the base 13 are engaged, the side of the spring piece 12 needs to be reset by the cooperation of the second lifting mechanism 5 and the outward expansion rod 6. The second lifting mechanism 5 is installed inside the frame 1 to drive the outward expansion rod 6 to move up and down. When the outward expansion rod 6 moves down, it can extend into the base 13 and squeeze the inner wall of the spring piece 12, so that the inner wall of the spring piece 12 expands outward, thereby resetting. In this embodiment, the first lifting mechanism 3 drives the pressing column 4 to press down the spring piece 12, so that the spring piece 12 is pressed down to engage with the base 13. During the pressing process, the side wall of the spring piece 12 is squeezed and deformed inward by the base 13. After the engagement is completed, the second lifting mechanism 5 drives the outward expansion rod 6 to move down and squeeze the inner side wall of the spring piece 12, so that the side wall of the spring piece 12 expands outward and restores its deformation. This utility model allows the pressing and outward expansion processes of the spring piece 12 and the base 13 to be performed on the same equipment, eliminating the need for repeated loading and fixing, simplifying the production process and improving production efficiency.

[0021] Meanwhile, this utility model can also avoid the risk of a single point of failure causing a complete production stoppage. When the second lifting mechanism 5 fails and cannot drive the expansion rod 6 to complete the expansion of the spring piece 12, the first lifting mechanism 3 can drive the pressing column 4 to press the spring piece 12 and the base 13 together. When the first lifting mechanism 3 fails and cannot drive the pressing column 4 to press down, the second lifting mechanism 5 and the expansion rod 6 can be used to expand the spring piece 12 that has been pressed with the base 13, thus avoiding a complete production stoppage.

[0022] Furthermore, such as Figure 3 As shown, multiple expansion rods 6 are provided, each of which is respectively mounted on the second lifting mechanism 5. The bottom end of each expansion rod 6 faces the receiving groove 201, and the multiple expansion rods 6 surround the pressing column 4 to form a circle. Specifically, the pressing column 4 is rectangular, and there are 8 expansion rods 6. The four sides of the pressing column 4 correspond to two expansion rods 6 respectively. The multiple expansion rods 6 can make the sidewalls of the spring piece 12 reset evenly.

[0023] Furthermore, such as Figure 4As shown, the outer side of the pressing column 4 is provided with multiple vertically opened guide grooves 401, and each of the outward expansion rods 6 is slidably disposed in each of the guide grooves 401 and corresponds to it. Specifically, when the first lifting mechanism 3 drives the pressing column 4 to complete the engagement of the spring piece 12 with the base 13, the pressing column 4 stops moving. At this time, the second lifting mechanism 5 drives the outward expansion rod 6 to move downward. The outward expansion rod 6 will move along the slotting direction of the guide groove 401. The guide groove 401 has a limiting effect on the outward expansion rod 6, preventing the outward expansion rod 6 from deviating when pressing the spring piece 12, so as to ensure that the equipment can better complete the outward expansion process of the spring piece 12.

[0024] In this embodiment, in the integrated pressing and expanding device for the spring sheet 12 and the base 13, the first lifting mechanism 3 includes a first cylinder 301, a first piston rod 302, and a first connecting plate 303. The first cylinder 301 is fixedly installed inside the frame 1. One end of the first piston rod 302 is connected to the first cylinder 301 and driven by the first cylinder 301. The first connecting plate 303 is connected to the other end of the first piston rod 302. The top end of the pressing column 4 is connected to the bottom side of the first connecting plate 303, which can be done by existing welding, screwing, or other methods. The expanding rod 6 passes through the first connecting plate 303. Specifically, the first cylinder 301 is used to drive the first piston rod 302 to move up and down, thereby driving the first connecting plate 303 and the pressing column 4 to move up and down.

[0025] like Figure 5 and Figure 6 As shown, further, in the integrated pressing and expanding device of the spring sheet 12 and the base 13, the second lifting mechanism 5 includes a second cylinder 501, a second piston rod 502 and a second connecting plate 503. The second cylinder 501 is fixedly installed in the frame 1. One end of the second piston rod 502 is connected to the second cylinder 501 and driven by the second cylinder 501. The second connecting plate 503 is connected to the other end of the second piston rod 502. The top end of the expanding rod 6 is connected to the bottom side of the second connecting plate 503. The connection can be made by existing welding, screwing, snap-fitting or other methods. The second connecting plate 503 is located above the first connecting plate 303. Specifically, the second cylinder 501 is used to drive the second piston rod 502 to move up and down, thereby driving the second connecting plate 503 and the outward expansion rod 6 to move up and down. When the first connecting plate 303 stops moving, the first connecting plate 303 can limit the second connecting plate 503. That is, when the outward expansion rod 6 completes the outward expansion process of the spring piece 12, the first connecting plate 303 and the second connecting plate 503 abut against each other to prevent the outward expansion rod 6 from continuing to move downward and causing damage to the spring piece 12.

[0026] Furthermore, in the integrated pressing and expanding device for the spring sheet 12 and the base 13, the second lifting mechanism 5 further includes a third connecting plate 504. The third connecting plate 504 has an insertion hole 5041 and is detachably mounted on the bottom side of the second connecting plate 503. The top end of the expanding rod 6 is located within the insertion hole 5041 and connected to the third connecting plate 504. Specifically, the top end of the expanding rod 6 is located within the insertion hole 5041 and welded to the third connecting plate 504. The inner wall of the insertion hole 5041 is flush with the outer side of the expanding rod 6. The insertion hole 5041 enhances the fixing effect of the expanding rod 6, preventing it from shifting when the spring sheet 12 is compressed. Simultaneously, the third connecting plate 504 is bolted to the second connecting plate 503 to facilitate disassembly and assembly of the third connecting plate 504.

[0027] In this embodiment, a protrusion 601 is provided on the side of the bottom end of the expanding rod 6 close to the spring piece 12, and an inclined surface 602 is provided between the protrusion 601 and the bottom end face of the expanding rod 6. Specifically, the protrusion 601 is used to press the inner sidewall of the spring piece 12, and the inclined surface 602 is used to guide the bottom end of the expanding rod 6 so that the bottom end of the expanding rod 6 can move down into the interior of the spring piece 12.

[0028] Furthermore, the integrated pressing and expanding device for the spring sheet 12 and base 13 also includes a control console 7 and a start / stop button 8. The control console 7 is located at the bottom of the frame 1. The first cylinder 301 and the second cylinder 501 are electrically connected to the control console 7. The start / stop button 8 is located on the outside of the control console 7 and is electrically connected to it. Specifically, there are two start / stop buttons 8, and the two start / stop buttons 8 are evenly electrically connected to the control console 7. Only when the operator presses both start / stop buttons 8 will the control console 7 activate the first cylinder 301 and the second cylinder 501 to complete the pressing and expanding process. The dual start / stop buttons 8 provide protection for the operator.

[0029] like Figure 7 As shown, further, the integrated pressing and expanding device for the spring piece 12 and the base 13 also includes a sensor 9. The sensor 9 is disposed inside the first cylinder 301 and electrically connected to the control console 7. When the sensor 9 senses that the pressing column 4 has completed the pressing operation, the second lifting mechanism 5 drives the expanding rod 6 to move downward to expand the inner wall of the spring piece 12. Specifically, the sensor 9 is a stroke sensor used to sense the movement stroke of the first piston rod 302. When the first piston rod 302 moves down a certain distance, it can drive the pressing column 4 to press the spring piece 12 and the base 13 together. After the sensor 9 senses that the first piston rod 302 has moved down a certain distance, it sends a signal to the control console 7, causing the control console 7 to start the second cylinder 501 to complete the expanding process of the spring piece 12.

[0030] In this embodiment, the integrated pressing and expanding device for the spring sheet 12 and the base 13 also includes a power switch 10 and a pause button 11. The power switch 10 is located on the outside of the control console 7 and is electrically connected to the control console 7, and is used to control the device to disconnect or connect to the external power supply. The pause button 11 is located on the outside of the control console 7 and is electrically connected to the control console 7, and is used to stop the movement of the first cylinder 301 or the second cylinder 501 in an emergency, thereby improving the safety of the operator.
