[0003] In the current related technologies, when riveting brackets on the condenser side plates, the method is to use solder pads and blind rivets to rivet the side plates and brackets with a riveting gun. The steps are as follows: ① First, place the rivets on the tooling; ② Place the side plate on top of the rivets (the rivets should be inserted into the holes of the side plate); ③ Place the solder pad on the side plate; ④ Place the bracket; ⑤ Use the riveting gun to rivet the rivets one by one (usually 5 brackets need to be riveted on each condenser side plate).

[0004] However, the disadvantages of the existing riveting method are as follows:

[0005] 1. When riveting, the rivets need to be riveted one by one, and the efficiency is extremely low.

[0034] The following will make a detailed description of the specific implementation manners of the application of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0035] In the technical solution disclosed in the application of the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, left, right" are usually defined based on the drawing direction of the corresponding drawing, and "inside, outside" refer to the inside and outside relative to the contour of the component or structure itself. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0036] According to the present utility model, an application discloses a riveting tooling for a side plate and a bracket, as Figure 1 , Figure 4 , Figure 5As shown, it includes a riveting frame 1. The riveting frame 1 includes a bottom plate 103 and a top plate 101. The top plate 101 is fixedly connected to the bottom plate 103 through support columns 102. A bottom support 104 is installed on the bottom plate 103. The riveting frame 1 is further provided with:

[0037] A positioning mechanism 6, combined with Figure 1 、 Figure 5 As shown, it is arranged on the bottom support 104 and is used for placing and positioning the side plate 7 and several brackets 5;

[0038] A riveting mechanism 3, as shown in the figure, is vertically and slidably arranged below the top plate 101 above the positioning mechanism 6 and is used for riveting the side plate 7 and the brackets 5;

[0039] A driving mechanism 2, combined with Figure 1 As shown, it is arranged on the top plate 101 and is used for driving the riveting mechanism 3;

[0040] A reset mechanism 4, combined with Figure 1 As shown, it is arranged on the bottom support 104 and is used for restoring the riveting mechanism 3 to its initial position.

[0041] In the above technical solution, when the operator is riveting, all the brackets 5 and side plates 7 are placed in the riveting tooling. The positioning mechanism 6 is used to accurately position and calibrate the specific parts on the side plate 7 that need to be riveted with the brackets 5. Then, the driving mechanism 2 is used to drive the riveting mechanism 3 to rivet the side plate 7 and the brackets 5. After the riveting is completed, the reset mechanism 4 is used to restore the riveting mechanism 3 to its initial position for the riveting of the next part.

[0042] This riveting tooling replaces the rivet gun and avoids the need to rivet the rivets one by one when using a rivet gun. With this tooling, all the brackets 5 that need to be riveted on the side plate 7 can be riveted at one time. The entire riveting process is accurately completed by various mechanisms such as the driving mechanism 2 and the riveting mechanism 3 of this tooling, ensuring the standardization and uniformity of the riveted products. It not only liberates manpower but also greatly reduces the possibility of loosening after riveting and the occurrence of poor welding during the subsequent brazing process, which may lead to accidents such as bracket fractures after loading, fully ensuring the quality of the products. This design enables the operator to effectively improve the riveting efficiency when riveting the side plate 7 and the brackets 5, significantly improves the quality of product riveting, maximally avoids the generation of defective products, and ultimately achieves the purpose of improving economic benefits.

[0043] In this embodiment, as Figure 2 、 Figure 3 shown, the positioning mechanism 6 includes:

[0044] A plurality of bracket positioning blocks 602 are arranged on the base 104 at intervals. A positioning groove 602a for accommodating the bracket 5 is formed on the upper end surface of each bracket positioning block 602. Before riveting, the operator places each bracket 5 into the corresponding positioning groove 602a;

[0045] A plurality of side plate support blocks 601 are installed on the base 104 between two adjacent bracket positioning blocks 602. A positioning groove 601a for accommodating the side plate 7 is formed on the upper end surface of each side plate support block 601. The side plate support block 601 is used to support and limit the side plate 7. After the operator aligns and places the brackets 5, the parts of the side plate 7 to be riveted are placed on each bracket 5, and the remaining parts of the side plate 7 are placed on each side plate support block 601. The positioning groove 601a is used to prevent the side plate 7 from shifting during the operation, ensuring the accuracy of riveting. In some embodiments, as Figure 5 shown, the positioning mechanism 6 further includes a limiting member 605 installed on the base 104 and used to abut against one end of the side plate 7. One end of the side plate 7 abuts against the limiting member 605, which also prevents the side plate 7 from shifting during the operation and further ensures the accuracy of riveting the side plate 7.

[0046] In this embodiment, as Figure 6 shown, the driving mechanism 2 includes:

[0047] A cylinder 201 is fixedly installed on the upper end surface of the top plate 101, and the telescopic rod 201a of the cylinder 201 penetrates downward through the top plate 101;

[0048] Guide rods 203 are respectively located on both sides of the cylinder 201 to ensure the accuracy of the cylinder 201 when pressing downward. The guide rods 203 are vertically slidably inserted into the top plate 101 through bearings 202 embedded in the top plate 101. The bottom ends of the guide rods 203 and the telescopic rod 201a are both fixedly connected to a connecting block 204.

[0049] A pressing plate 205 is fixedly installed on the lower end surface of the connecting block 204. The lower end surface of the pressing plate 205 is connected to the riveting mechanism 3 and is used to drive the riveting mechanism 3 to move up and down. Among them, the pressing plate 205 can be fixedly connected to the connecting block 204 by welding, or the pressing plate 205 can be partially inserted into the connecting block 204, and then the two are fixed by using a knob plunger 206. No specific limitation is made here.

[0050] In this embodiment, as Figure 6 、 Figure 7 、 Figure 8 shown, the riveting mechanism 3 includes:

[0051] A number of expanding heads 303 are vertically and fixedly installed on the lower end surface of the pressure plate 205, and each expanding head 303 corresponds to the positioning groove 602a of the lower support positioning block 602 respectively;

[0052] The unloading spring 302 has its top fixedly installed on the lower end surface of the pressure plate 205, and a unloading column 301 vertically fixedly installed on the lower end surface of the pressure plate 205 is inserted into the unloading spring 302;

[0053] The lower pressure plate 304 has its upper end surface fixedly connected to the lower end of the unloading spring 302, and the expanding head 303 and the unloading column 301 are slidably inserted through the lower pressure plate 304. The lower pressure plate 304 matches the length of the side plate 7 and is used to press the side plate 7.

[0054] In this solution, a number of expanding heads 303 are used for riveting each support 5. Compared with the prior art where the rivets cannot be taken out after riveting and a large number of rivets are required for the riveting process, the expanding heads 303 in this tooling can be used repeatedly. The function of the unloading spring 302 is that during riveting, the unloading spring 302 compresses and deforms to make the support 5 and the side plate 7 in a tightly attached state. After riveting is completed, the cylinder 201 returns. First, the expanding head 303 is withdrawn from the side plate 7. At the same time, under the action of the unloading spring 302 and the lower pressure plate 304, it is ensured that the side plate 7 will not be taken out together. After the expanding head 303 is completely separated from the side plate 7, the entire riveting mechanism 3 is reset.

[0055] In this embodiment, as Figure 5 shown, the positioning mechanism 6 further includes a positioning sleeve 603. The positioning sleeve 603 is installed on the bottom support 104, and a positioning column 604 corresponding to the positioning sleeve 603 is installed on the lower end surface of the pressure plate 205, and the positioning column 604 is slidably inserted through the lower pressure plate 304. During riveting, the positioning column 604 will be inserted into the corresponding positioning sleeve 603 to play a role in positioning the riveting to ensure the accuracy of riveting.

[0056] In this embodiment, as Figure 5 shown, the reset mechanism 4 specifically includes:

[0057] Guide columns 403 are respectively vertically installed at the four corners of the upper end surface of the bottom support 104. The upper ends of the guide columns 403 are slidably inserted through the pressure plate 205 through the guide sleeves 401 embedded in the pressure plate 205, and the pressure plate 205 moves up and down along the guide columns 403;

[0058] Reset springs 402 are sleeved on the guide columns 403. One end of the reset spring 402 contacts the bottom support 104, and the other end contacts the guide sleeve 401.

[0059] In this embodiment, as Figure 1 、 Figure 4As shown in the figure, it further includes a grating 8, which is respectively installed at both ends of the riveting frame 1, and both ends of the grating 8 are fixedly connected to the bottom plate 103 and the top plate 101 respectively. The grating 8 serves as an anti-mistake mechanism for this tooling. During the riveting process, if the operator accidentally puts his hand into the riveting frame 1 and it is sensed by the grating 8, the air cylinder 201 will stop driving and the riveting mechanism 3 will stop riveting to ensure the safety of the operator.

[0060] The use steps of this riveting tooling of the present utility model application are exemplarily described as follows:

[0061] S1. First, place the bracket 5 into the positioning groove 602a of the bracket positioning block 602;

[0062] S2. Then, place the side plate 7 on the bracket 5, and the rest of the side plate 7 is supported by the side plate support block 601;

[0063] S3. Start the air cylinder 201, and drive the lower pressing plate 304 to move downward by using the pressing plate 205. That is, first, the lower pressing plate 304 will press the side plate 7 and the bracket 5 tightly together, and then the air cylinder 201 continues to move downward. The pressing plate 205 and the lower pressing plate 304 compress the unloading spring 302 and ensure that the bracket 5 and the side plate 7 are in a tightly attached state. At this time, the expanding head 303 moves downward to expand the flanging of the side plate 7, so that the side plate 7 and the bracket 5 are riveted together to complete the tightening action;

[0064] S4. After the riveting is completed, the air cylinder 201 drives the expanding head 303 to withdraw from the side plate 7 first. At the same time, under the action of the lower pressing plate 304 and the unloading spring 302, it is ensured that the side plate 7 will not be lifted together. When the expanding head 303 completely withdraws from the flanging of the side plate 7, the unloading spring 302 is released, and the riveting mechanism 3 is completely restored to the initial position by using the reset mechanism 4;

[0065] S5. Take out the riveted side plate 7 and rivet the next side plate 7.

[0066] The preferred embodiments of the present utility model application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the specific details in the above embodiments.
