Description

Technical Field

[0001] This utility model relates to a riveting device, specifically, to a riveting device for an outer cover of a temperature controller. Background Technology

[0002] The temperature controller is an automatic control element that generates a conduction or disconnection action by physically deforming the inside of the switch according to the temperature change of the working environment. During the production process of the temperature controller, the outer cover 5 and the outer shell 4 of the temperature controller need to be tightly riveted together. A boss 41 is fixedly connected to the top edge of the outer shell 4, and there must be no gap between the upper surface of the outer cover 5 and the outer shell 4. Otherwise, the bimetallic strip will be inserted into the gap, affecting the trip temperature and the reset temperature.

[0003] However, most existing riveting devices use rollers for riveting. When riveting the outer shell 4 and the outer cover 5, the workers place the outer shell 4 and the outer cover 5 on the rollers. The rollers have mounting brackets on both sides to restrict the position of the outer shell 4 and the outer cover 5. The heat-sensing surface of the outer cover is on the same plane as the mounting brackets. As the rollers rotate, they easily rub against the mounting brackets, causing the mounting brackets and the outer cover 5 to be lifted as a whole, while the position of the outer shell 4 remains unchanged. This results in a gap between the moving outer cover 5 and the upper surface of the outer shell 4, making it easy for gaps to remain after riveting, which affects the subsequent processing of the outer cover 5 and the outer shell 4. In view of this, we propose an outer cover riveting device for temperature controllers. Utility Model Content

[0004] The purpose of this utility model is to provide a riveting device for the outer cover of a temperature controller, so as to solve the problem that the roller riveting device mentioned in the background art is prone to lifting the mounting bracket and the outer cover as a whole during use, causing a gap between the upper surface of the outer cover and the outer shell, which affects the riveting effect between the two.

[0005] To address the aforementioned problems, the present invention aims to provide a riveting device for a temperature controller housing, comprising a base, a column fixedly connected to one end of the upper side of the base, a top plate fixedly connected to the upper side of the column, a pressing mechanism on the top plate for pressing the outer shell and the housing together, a positioning mechanism on the upper side of the base for fixing the position of the outer shell and the housing, the positioning mechanism including a slide plate fixedly connected to the upper side of the base, a limiting component and a moving component on the upper side of the slide plate, the limiting component for limiting the position of the outer shell, a support frame fixedly connected to one end of the upper side of the slide plate, the limiting component being located between the support frame and the moving component, a pressing component being provided on the top of the support frame and the upper side of the moving component, the moving component driving one of the pressing components to move towards or away from the other pressing component, and the limiting component being located between the two pressing components.

[0006] As a further improvement to this technical solution, the limiting component includes a first slider slidably connected to the upper side of the slide plate, a first template fixedly connected to the upper side of the first slider, a connecting plate fixedly connected to the side of the first template near the moving component, and a groove penetrating the connecting plate is provided on the connecting plate.

[0007] As a further improvement to this technical solution, a limiting groove is provided at the top of the first template. The dimensions of the limiting groove cross-section are adapted to the dimensions of the outer shell cross-section. The outer shell is placed inside the limiting groove, and the outer side wall of the outer shell is in contact with the side wall of the limiting groove.

[0008] As a further improvement to this technical solution, the moving component includes a second slider slidably connected to the upper side of the slide plate. Several support blocks are fixedly connected to the upper side of the second slider. The support block located in the middle is located inside the slide groove. During the process of the second slider moving towards the support frame, the moving second slider contacts the first slider and drives it to move synchronously. During the process of the second slider moving away from the support frame, the moving second slider and the support blocks drive the connecting plate to move, causing it to pull the first slider to move synchronously.

[0009] As a further improvement to this technical solution, the extrusion assembly includes a second template, with two second templates respectively fixedly connected to the top of the support frame and the upper side of several support blocks.

[0010] As a further improvement to this technical solution, a stepped semicircular groove with its top and bottom penetrating through the second template is provided on the side of the two second templates that are close to each other. The diameter of the top of the stepped semicircular groove is larger than the diameter of the bottom, and the dimensions of the stepped semicircular groove cross-section are adapted to the cross-sectional dimensions of the top of the outer shell and the boss assembly.

[0011] As a further improvement to this technical solution, a positioning plate is fixedly connected to the upper side of the second template. The two positioning plates are provided with positioning grooves that penetrate the top and bottom of the positioning plates on the side that is close to each other. The dimensions of the positioning groove cross-section are adapted to the dimensions of the outer cover cross-section.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The temperature controller uses an outer cover riveting device. The operator places the outer shell inside the limiting groove, and then places the outer cover on the upper side of the outer shell. The operator pushes the second slider to move, and the moving second slider drives the first slider to move closer to the support frame. Under the synergistic compression of the two extrusion components, the position and angle of the outer cover and the outer shell are adjusted so that the position of the outer cover and the outer shell corresponds and the upper surface of the outer cover and the outer shell fits together to avoid gaps between the two. Then the pressing mechanism presses the upper side of the outer cover to rivet it together with the outer shell to complete the tight riveting of the outer cover and the outer shell.

[0028] 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.

[0029] Example

[0030] Please see Figure 1 - Figure 8 As shown, the purpose of this embodiment is to provide a riveting device for a temperature controller housing, including a base 1. A column 11 is fixedly connected to one end of the upper side of the base 1. A top plate 12 is fixedly connected to the upper side of the column 11. A pressing mechanism 2 is provided on the top plate 12. The pressing mechanism 2 is used to press the outer shell 4 and the outer cover 5 together to rivet them together. The pressing mechanism 2 includes a cylinder 21 fixedly connected to the upper side of the top plate 12. The piston rod of the cylinder 21 passes through the top plate 12 and is fixedly connected to a pressing plate 22. A pressing rod 23 is fixedly connected to the lower side of the pressing plate 22. During the extension and retraction of the piston rod of the cylinder 21, it drives the pressing plate 22 and the pressing rod 23 to move upward or downward. A pressing mechanism 23 is provided on the upper side of the base 1. There is a positioning mechanism 3, which is used to fix the position of the outer shell 4 and the outer cover 5, so that the outer cover 5 is in contact with the upper end surface of the outer shell 4. When the pressing rod 23 moves downward, its bottom contacts the upper side of the outer cover 5. The moving pressing rod 23 presses the outer cover 5 downward to rivet it together with the outer shell 4. Infrared sensors are installed on the upper side of the base 1 at the positions on both sides of the positioning mechanism 3. The infrared sensors are existing technology and will not be improved in this solution, so they will not be described here. The height of the infrared sensors is higher than the height of the positioning mechanism 3. The infrared sensors detect whether there are workers' palms or other objects under the pressing mechanism 2, so as to avoid the pressing mechanism 2 squeezing the workers' palms and causing them to be injured during use.

[0031] refer to Figure 5 - Figure 8The positioning mechanism 3 includes a slide plate 31 fixedly connected to the upper side of the base 1. A limiting component and a moving component are provided on the upper side of the slide plate 31. The limiting component restricts the position of the outer casing 4. A support frame 332 is fixedly connected to one end of the upper side of the slide plate 31. The limiting component is located between the support frame 332 and the moving component. A pressing component is provided on the top of the support frame 332 and the upper side of the moving component. The moving component drives one of the pressing components to move closer to or further away from the other pressing component. The limiting component is located between the two pressing components. The operator places the outer shell 4 on the upper side of the limiting component and the outer cover 5 on the upper side of the outer shell 4. Then, the operator pushes the moving component to move the extrusion component closer to the limiting component. When the moving component contacts the limiting component, the moving component moves the limiting component closer to the support frame 332. As the two extrusion components gradually approach each other, the two extrusion components extrude the top of the outer shell 4, the boss 41, and the outer cover 5 to limit the position of the outer shell 4 and the outer cover 5, prevent them from rotating during the riveting process, and improve the riveting effect of the outer shell 4 and the outer cover 5.

[0032] refer to Figure 5 - Figure 8 The limiting component includes a first slider 32 slidably connected to the upper side of the slide plate 31. A first template 321 is fixedly connected to the upper side of the first slider 32. A connecting plate 323 is fixedly connected to the side of the first template 321 near the moving component. A groove is provided on the connecting plate 323 that passes through the connecting plate 323. A limiting groove 322 is provided on the top of the first template 321. The cross-sectional dimensions of the limiting groove 322 are adapted to the cross-sectional dimensions of the outer shell 4. The outer shell 4 is placed inside the limiting groove 322, and the outer side wall of the outer shell 4 contacts the side wall of the limiting groove 322. When the operator places the outer shell 4 on the first template 321, the bottom of the outer shell 4 is located inside the limiting groove 322. The outer shell 4 can easily fit against the inner wall of the limiting groove 322, and the outer shell 4 is prevented from shaking under the restriction of the limiting groove 322.

[0033] The extrusion assembly includes a second template 333. The two second templates 333 are provided with stepped semicircular grooves 334 that penetrate the top and bottom of the second templates 333 on the side close to each other. The cross-sectional dimensions of the stepped semicircular grooves 334 are adapted to the cross-sectional dimensions of the top of the outer shell 4 and the boss 41 assembled together. The diameter of the top of the stepped semicircular grooves 334 is larger than the diameter of the bottom. When the two second templates 333 abut against each other, the top of the outer shell 4 and the boss 41 are located in the stepped semicircular groove formed by the two stepped semicircular grooves 334. The outer shell 4 and the boss 41 are in contact with the inner wall of the stepped semicircular grooves 334. The stepped semicircular grooves 334 restrict the position of the outer shell 4 and the boss 41 to improve their stability during the riveting process.

[0034] A positioning plate 335 is fixedly connected to the upper side of the second template 333. The two positioning plates 335 are provided with positioning grooves 336 that penetrate the top and bottom of the positioning plates 335 on the side close to each other. The cross-sectional dimensions of the positioning groove 336 are adapted to the cross-sectional dimensions of the outer cover 5. When one of the positioning plates 335 moves towards the outer cover 5, if the outer cover 5 tilts, one end of the outer cover 5 contacts the inner wall of the positioning groove 336. Under the pressure of the positioning plate 335, one end of the outer cover 5 slides along the inner wall of the positioning groove 336, thereby rotating the outer cover 5 to fit against the inner wall of the positioning groove 336. As the positioning plate 335 and the outer cover 5 continue to move, the two positioning plates 335 abut together to press the outer cover 5, thereby fixing the position of the outer cover 5. When the outer cover 5 and the outer shell 4 are riveted, the outer cover 5 moves downward along the positioning groove 336 to be riveted.

[0035] refer to Figure 5 - Figure 8 The moving component includes a second slider 33 slidably connected to the upper side of the slide plate 31. A push-pull plate is fixedly connected to the side of the second slider 33 away from the first slider 32, so that the operator can hold the push-pull plate to pull or push the second slider 33 to move. Two movable grooves are opened on the opposite side walls of the slide plate 31. Limiting blocks are fixedly connected to the bottom of the first slider 32 and the second slider 33. The limiting blocks are slidably connected inside the movable grooves. The first slider 32 and the second slider 33 move along the axial direction of the limiting plate. Under the restriction of the limiting blocks and the movable grooves, the first slider 32 and the second slider 33 are prevented from detaching from the slide plate 31, so as to prevent the first slider 32 and the second slider 33 from detaching from the slide plate 31. A stop bar is fixedly connected to the upper side of the base 1 near the second slider 33. The stop bar prevents the second slider 33 from sliding out of the slide plate 31.

[0036] Several support blocks 331 are fixedly connected to the upper side of the second slider 33. The support block 331 in the middle is located inside the slide groove. Two second templates 333 are fixedly connected to the top of the support frame 332 and the upper side of the several support blocks 331, respectively. As the second slider 33 moves towards the support frame 332, the moving second slider 33 contacts the first slider 32 and drives it to move synchronously. An electromagnet 13 is fixedly connected to the upper side of the base 1 near the support frame 332. A limit switch is provided on the side of the electromagnet 13 away from the support frame 332. When the first... When slider 32 contacts electromagnet 13, the moving first slider 32 pushes electromagnet 13 to move and presses the limit switch. When the limit switch is pressed, the control pressing mechanism 2 is activated, so that the pressing mechanism 2 rivets the outer cover 5 to the outer shell 4. As the second slider 33 moves away from the support frame 332, the moving second slider 33 and the support block 331 drive the connecting plate 323 to move, so that it pulls the first slider 32 to move synchronously. The moving first slider 32 drives the riveted outer cover 5 and outer shell 4 away from the support frame 332, so that the staff can take them out.

[0037] When using this device:

[0038] In the initial state, the moving component and the limiting component are located away from the support frame 332 and are separated from each other. When it is necessary to rivet the outer cover 5 and the outer shell 4, the operator puts the bottom of the outer shell 4 into the inside of the limiting groove 322 and places the outer cover 5 on the upper side of the outer shell 4 so that the bottom of the outer cover 5 fits against the upper surface of the outer shell 4.

[0039] Subsequently, the staff pushed the second slider 33 to move one of the positioning plates 335 towards the direction of the outer cover 5. The moving positioning plate 335 contacted one end of the outer cover 5 and squeezed and rotated, so that the outer cover 5 was in contact with the inner wall of the positioning groove 336. When the second slider 33 contacted the first slider 32, the moving second slider 33 drove the first slider 32 to move towards the direction of the support frame 332.

[0040] When the two second templates 333 and the two positioning plates 335 come into contact with each other, the outer shell 4 and the outer cover 5 are located inside the stepped semicircular groove 334 and the positioning groove 336 respectively, which improves the stability of the outer shell 4 and the outer cover 5 during the riveting process under the constraint of the stepped semicircular groove 334 and the positioning groove 336.

[0041] The first slider 32 moves and presses the limit switch by the electromagnet 13. At this time, the central axes of the outer cover 5, the outer shell 4 and the pressing rod 23 coincide. The piston rod of the cylinder 21 extends and drives the lower pressure plate 22 and the pressing rod 23 to move downward. The moving pressing rod 23 drives the outer cover 5 to move downward and rivet it together with the outer shell 4.

[0042] After the outer cover 5 and the outer shell 4 are riveted together, the worker pulls the second slider 33 to move away from the support frame 332. When the support block 331 contacts the other end of the slide, the moving support block 331 drives the connecting plate 323 to move, so that it pulls the first slider 32 away from the support frame 332, so that the worker can take out the riveted outer cover 5 and the outer shell 4.
