Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a clamping and welding structure. Background Art

[0002] During the processing of workpieces, it is necessary to clamp and maintain stability. For example, during the production of combined product parts such as the frames and middle plates of tablet computers, mobile phones, and laptop computers, the back plate needs to be clamped with aluminum alloy frames and titanium alloy frames before welding. For clamping molds, the most commonly used structure at present is the inclined guide pillar core-pulling structure, which mostly clamps on both sides and has a relatively fixed application scenario.

[0003] In addition, since the heat generated during the welding of workpieces has a heating effect on the tooling, it is easy to scald equipment operators during the welding operation. Summary of the Utility Model

[0004] In view of this, the utility model aims to solve at least one of the problems in the related art to a certain extent. For this reason, the purpose of the utility model is to provide a clamping and welding structure.

The water-cooling channel is used to cool the workpiece when welding the workpiece. The water-cooled plate is fixedly arranged on the plurality of clamping components, and the plurality of clamping components synchronously clamp the workpiece on multiple sides.

The slider includes a clamping surface on the side opposite to the second inclined surface, and the clamping surface contacts the workpiece. The driving mechanism can drive the wedge block and the first guide post to move up and down together. When the first guide post moves up and down, it drives the slider to move horizontally in the direction towards the central region. When the wedge block moves up and down, the first inclined surface contacts the second inclined surface.

[0011] In some embodiments, the clamping mechanism further includes a pressure rod and a hinge pin. The hinge pin is rotatably connected to the pressure rod. When the wedge block rises, the top surface of the wedge block contacts the tail of the pressure rod, causing the pressure rod to rotate around the hinge pin and synchronously pressing the workpiece through the pressure rod.

[0014] In some embodiments, the control member is a button box, and the button box is provided with buttons for controlling the opening or clamping of the clamping mechanism.

[0031] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0032] Please refer to Figure 1 , this application provides a clamping and welding structure 100. The clamping and welding structure 100 includes a water-cooled plate 10 and a plurality of clamping assemblies 20. The water-cooled plate 10 is located in the central area 201 surrounded by the plurality of clamping assemblies 20. The water-cooled plate 10 is used to place the workpiece. A water-cooling channel is provided inside the water-cooled plate 10, and a coolant is stored inside the water-cooling channel. The water-cooling channel is used to cool the workpiece when welding the workpiece. The water-cooled plate 10 is fixedly arranged on the plurality of clamping assemblies 20, and the plurality of clamping assemblies 20 synchronously clamp the workpiece on multiple sides.

[0033] Specifically, a water-cooling channel is provided inside the water-cooled plate 10. When welding the workpiece after clamping the workpiece by the plurality of clamping assemblies 20, the cold water in the water-cooling channel can be used to cool the whole workpiece or the welding part, so as to reduce the heating effect of the heat generated during the welding process on the clamping and welding structure and avoid scalding the equipment operator.

[0034] The water-cooling channel can be composed of one or more "S"-shaped tracks, straight tracks, "X"-shaped tracks, loop tracks or other forms of tracks, which are not limited herein. A coolant can be stored inside the water-cooling channel. The coolant can be, for example, water or other liquids, which are not limited herein.

[0035] The number of multiple clamping components 20 can be 2, 3, 4, 5, 6, 7, 8, 9, 10 or 11, without limitation here. That is to say, in this application, the number of clamping components 20 is set to clamp the workpiece through different numbers of clamping surfaces, so as to be applicable to different assembly and welding scenarios. Or rather, the number of clamping components 20 in this application can be increased or decreased according to different assembly or welding scenarios, and it can be applicable to the assembly and welding of multiple scattered workpieces, and can be applicable to a variety of assembly and welding scenarios.

[0036] The workpiece can include, for example, the aluminum-titanium alloy frame and the backplane in the combined product parts such as the frame and the middle plate of a tablet computer, a mobile phone, a laptop computer, etc. After the aluminum-titanium alloy frame and the backplane are multi-facially clamped by the clamping and welding structure 100 of this application, the aluminum-titanium alloy frame and the backplane can be welded to achieve a more stable welding operation. Among them, the welding method for the aluminum-titanium alloy frame and the backplane can be, for example, friction stir welding or other welding methods, without limitation here.

[0037] Thus, the clamping and welding structure 100 of this application includes multiple clamping components 20 and a water-cooling plate 10. The water-cooling plate 10 is used to place the workpiece. The multiple clamping components 20 synchronously clamp the workpiece on multiple sides, which can be applicable to the assembly and welding of multiple scattered workpieces, and when welding the workpiece, the workpiece can be cooled through the water-cooling channels in the water-cooling plate 10, which can effectively reduce the heating effect of the heat generated during the welding process on the clamping and welding structure and prevent the equipment operator from being scalded.

[0038] In addition to directly fixedly connecting the water-cooling plate 10 for placing the workpiece with multiple clamping components 20, making the structure of the clamping and welding structure 100 relatively simple and light in weight, the clamping and welding structure 100 of this application can also be indirectly fixedly connected with multiple clamping components 20 through a fixing plate 30. The fixing plate 30 can provide a fixed installation platform for the water-cooling plate 10, and can reinforce the thickness of the workpiece placement area, making the entire clamping and welding structure 100 more stable. In the drawings of this application, the clamping and welding structure 100 is illustrated by taking the fixing plate 30 and the water-cooling plate 10 as examples.

[0039] Specifically, please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments of this application, the clamping and welding structure 100 further includes a fixing plate 30. The fixing plate 30 is fixedly installed on the same horizontal plane of multiple clamping components 20, and the water-cooling plate 10 is fixed at the central position of the fixing plate 30, and the water-cooling channels are circulating water flow channels.

[0040] Among them, the clamping and welding structure 100 of the present application fixedly arranges the fixing plate 30 on the same horizontal plane of a plurality of clamping components 20, and the water-cooling plate 10 is fixed at the central position of the fixing plate 30. In this way, the water-cooling plate 10 can maintain a constant position on a certain horizontal plane of the clamping components 20, ensuring that the workpiece can be stably placed in the central area formed by surrounding the plurality of clamping components 20.

[0041] Specifically, the water-cooling plate 10 and the fixing plate 30 can be fixed by screws or by other means, which is not limited herein.

[0042] The area of the water-cooling plate 10 can be less than or equal to the area of the fixing plate 30. When the area of the water-cooling plate 10 is equal to the area of the fixing plate 30, the cooling area of the water-cooling plate 10 is maximized, which can further reduce the temperature rise effect of the heat generated during the workpiece welding process on the clamping and welding structure, and prevent the equipment operator from being scalded. When the area of the water-cooling plate 10 is less than the area of the fixing plate 30, it is beneficial to the lightweight design of the clamping and welding structure 100.

[0043] The water-cooling channel is a circulating water flow channel. That is to say, the water-cooling channel of the present application can be connected to an external water pipe, thereby forming a water circulation flow path, which can more effectively reduce the temperature rise effect of the heat generated during the workpiece welding process on the clamping and welding structure, and prevent the equipment operator from being scalded.

[0044] Through holes can be provided at the corresponding positions of the fixing plate 30 and the clamping components 20. The fixing plate 30 can be fixedly arranged on the plurality of clamping components 20 by screws passing through the through holes, or by other means, which is not limited herein.

[0045] Please refer to Figure 1 and Figure 2 , in one embodiment, the plurality of clamping components 20 include 4, and every two clamping components 20 are arranged oppositely. That is to say, the present application can form a central area 201 by surrounding with 4 clamping components 20, and every two clamping components 20 are arranged oppositely, so that the workpiece can be clamped from four sides, and it can be integrated into the automated assembly and welding scenario.

[0046] Please refer to Figure 3 , the clamping and welding structure 100 further includes a driving mechanism 40, and the clamping component 20 includes a clamping mechanism 21. The driving mechanism 40 drives the clamping mechanism 21 to move towards the central area 201 to clamp the workpiece synchronously, or drives the clamping mechanism 21 to move away from the central area 201 synchronously to release the workpiece.

[0047] That is to say, each clamping assembly 20 of the present application is provided with a corresponding clamping mechanism 21, and a plurality of clamping mechanisms 21 can be synchronously controlled by a driving mechanism 40 to move synchronously towards the central region 201 to clamp the workpiece. Correspondingly, the present application can also synchronously control a plurality of clamping mechanisms 21 to move away from the central region 201 by a driving mechanism 40 to release the workpiece.

[0048] In this way, the present application can drive a plurality of clamping mechanisms 21 to synchronously clamp or release the workpiece by a driving mechanism 40, and the driving control is relatively simple and fast.

[0049] The driving mechanism 40 of the present application can be a cylinder 41 and a gas-liquid intensifying cylinder 42, and the gas-liquid intensifying cylinder 42 increases the power for the cylinder 41. It can be understood that the gas-liquid intensifying cylinder 42 is a high-efficiency, energy-saving and environmentally friendly power source device, and realizes force increasing output through the combination of air pressure and liquid pressure.

[0050] That is to say, the clamping and welding structure 100 of the present application is driven by a hydraulic cylinder, but does not use the traditional hydraulic station mode, but uses a gas-liquid intensifying cylinder to replace the traditional hydraulic station, which is more concise and has lower cost.

[0051] In other embodiments of the present application, the cylinder 41 can also be used alone as the driving mechanism 40, which is not limited herein.

[0052] Please refer to Figure 3 、 Figure 4 and Figure 5 , in some embodiments, the clamping mechanism 21 includes a movable plate 211, a wedge block 212, a first guide post 213 and a slider 214. The movable plate 211 is connected to the driving mechanism 40, and the wedge block 212 is placed on the movable plate 211. The first guide post 213 is obliquely inserted into the movable plate 211, and the first guide post 213 is arranged obliquely outwardly diffusing with the central region 201 as the center. The wedge block 212 has a first inclined surface 2121 facing the central region, the slider 214 has a second inclined surface 2141 opposite to the first inclined surface 2121, and the slider 214 includes a clamping surface 2142 on the side opposite to the second inclined surface 2141, and the clamping surface 2142 contacts the workpiece.

[0053] The width h of the clamping surface 2142 corresponding to the slider 214 can be changed according to the different thicknesses of different workpieces. For example, in the case of a thinner workpiece, the slider 214 with a smaller width of the clamping surface 2142 can be replaced, and in the case of a thicker workpiece, the slider 214 with a larger width of the clamping surface 2142 can be replaced. That is to say, the slider 214 of the present application can clamp the workpiece corresponding to the width of the clamping surface 2142 through the clamping surface 2142.

[0054] In one embodiment, as Figure 3 andFigure 5 As shown, the slider 214 has a clamping portion protruding towards the central region 201, and the clamping portion has a clamping surface 2142 that contacts the workpiece. Since the clamping portion of the slider 214 protrudes towards the central region 201, a relatively stable bending and fixing region can be formed, and a water-cooling plate 10 can be placed in this bending and fixing region. That is, the water-cooling plate 10 can be fixedly installed above the fixing plate 30 to place the workpiece on the water-cooling plate 10 for clamping.

[0055] It should be noted that in other embodiments of the present application, the slider 214 may also not need to be provided with a clamping portion protruding towards the central region 201, and directly use the surface of the slider 214 facing the central region 201 as the clamping surface 2142 to clamp the workpiece.

[0056] The driving mechanism 40 can drive the wedge block 213 and the first guide post 213 to move up and down together. When the first guide post 213 moves up and down, it drives the slider 214 to move horizontally. When the wedge block 212 moves up and down, the first inclined surface 2121 contacts the second inclined surface 2141. That is, the clamping and welding structure 100 of the present application is a mechanical mechanism that can convert vertical movement into horizontal movement or inclined movement by the cooperation of the wedge block 213 and the inclined first guide post 213 with the slider 214.

[0057] Specifically, when the driving mechanism 40 is a gas-liquid booster cylinder 42 and a cylinder 41, the gas-liquid booster cylinder 42 increases the power for the cylinder 41, and the cylinder 41 can drive the movable plate 211 to rise or fall. The movable plate 211 drives the wedge block 212 and the inclined first guide post 213 to rise or fall. The first guide post 213 is inserted into the movable plate 211. When the first guide post 213 rises or falls, it drives the slider 214 to move horizontally, that is, the distance between the clamping surface 2142 of the slider 214 and the contact surface of the workpiece can be adjusted, so as to clamp or loosen the workpiece through the slider 214. That is, the clamping and welding structure 100 of the present application is driven by the cylinder 41, and a movable plate 211 can drive multiple sliders 214 to move.

[0058] At this time, when the cylinder 41 drives the movable plate 211 to rise and drives the wedge block 212 to rise or fall, the first inclined surface 2121 of the wedge block 212 contacts the second inclined surface 212 of the slider 214, which can prevent the slider 214 from retreating due to the reverse force of the workpiece.

[0059] In addition, due to the self-locking effect of the wedge block 212, a relatively large clamping and pressing force can be continuously provided to the workpiece, thus solving the welding defects caused by the opening effect of the welding tool on the splicing weld during the friction stir welding process.

[0060] That is to say, the clamping and welding structure 100 of the present application adopts the self-locking function of the wedge block 212 and the driving function of the inclined first guide post 213, and can realize the synchronous self-centering clamping of multiple scattered workpieces.

[0061] In some embodiments, a limiting groove 2111 is provided on the movable plate 211, and the wedge block 212 is placed in the limiting groove 2111. In this way, by providing the limiting groove 2111 on the movable plate 211, the present application can further effectively fix the position of the wedge block 212, so that the wedge block 212 can withstand the acting force of the slider 214, which is beneficial to the stability of the clamping and welding structure 100.

[0062] In addition, a stop block 2112 may be provided on the side of the movable plate 211 in contact with the first guide post 213. When the first guide post 213 is inserted into the movable plate 211, the guide post stop block 2112 provided on the movable plate 211 can block the first guide post 213, so that the first guide post 213 has a supporting action point on the movable plate 211 during the lifting movement, and the first guide post 213 can be more stably inclined on the movable plate 211. As Figure 4 shown, the inclination angle α of the first guide post 213 relative to the movable plate 211 may be 30°, 45° or other angles, which are not limited herein.

[0063] Please refer to Figure 3 、 Figure 4 and Figure 5 , the clamping mechanism 21 further includes a pressure bar 215 and a hinge pin 216. The pressure bar 215 is arranged above the wedge block 212, and the hinge pin 216 is located at one end of the pressure bar 215 close to the central region 201. The hinge pin 216 is rotatably connected to the pressure bar 215. When the wedge block 212 rises, the wedge block 212 exerts a force on the tail 2151 of the pressure bar 215, causing the pressure bar 215 to rotate around the hinge pin 216, and the workpieces are synchronously clamped through the pressure bar 215.

[0064] Among them, the pressure bar 215 may be a pressing element made of metal or a pressing element made of other materials, which is not limited herein.

[0065] It should be noted that the deflection angles of the pressing action and the reset action of the pressure bar 215 of the present application are relatively small. During the pressing action, the workpieces are mainly pressed by applying a downward pressure.

[0066] In this way, when the wedge block 212 rises, the clamping mechanism 21 of the present application can apply an upward force to the tail 2151 of the pressure bar 215, so that the head of the pressure bar 215 presses the workpieces, and thus the workpieces can be firmly attached to the tooling of the clamping and welding structure 100.

[0067] That is to say, the clamping welding structure 100 of the present application can realize the synchronous self-centering clamping of multiple scattered workpieces through the self-locking function of the wedge block 212 and the driving function of the inclined first guide column 213, and can also drive the pressure rod 215 to clamp the workpieces.

[0068] In addition, the clamping mechanism 21 of the present application may further include a pressure rod reset spring 217 and a spring stopper 218. The pressure rod reset spring 217 may be inserted in the middle of the top of the pressure rod 215, and the pressure rod reset spring 217 is used to restore the pressure rod 215 to its initial position. Specifically, when the wedge block 212 descends, the pressure rod reset spring 217 drives the pressure rod 215 to reset.

[0069] The spring stopper 218 is arranged above the pressure rod return spring 217. The spring stopper 218 is used to block the specific structure of the pressure rod return spring 217 to prevent the pressure rod return spring 217 from being exposed outside the clamping welding structure 100. It is more beautiful and can protect the pressure rod return spring 217 from being easily corroded or damaged.

[0070] See also Figure 3 and Figure 6 The clamping mechanism 21 further includes a second guide post 2191 and a bottom plate 2192. The fixing plate 30 is mounted on the plurality of second guide posts 2191, and the plurality of second guide posts 2191 are mounted on the bottom plate 2192.

[0071] Specifically, a guide post mounting seat 2193 corresponding to the second guide post 2191 may be further provided on the bottom plate 2192, and the second guide post 2191 may be fixedly mounted on the bottom plate 2192 through the corresponding guide post mounting seat 2193. A guide sleeve 2194 may be further provided where the second guide post 2191 is connected to the water-cooling plate 10, so that the connection between the second guide post 2191 and the fixing plate 30 may be more firmly established. The second guide post 2191 and the fixing plate 30 may be connected by bolts or in other ways, which are not limited here.

[0072] In this way, the fixing plate 30 of the present application can be fixedly installed on the clamping welding structure 100 through the support of the plurality of second guide pillars 2191 .

[0073] In addition, when the clamping welding structure 100 is not provided with the fixing plate 30 , the water-cooling plate 10 can also be directly installed on the plurality of second guide pillars 2191 , which can further reduce the weight of the clamping welding structure 100 .

[0074] See also Figure 1 The clamping welding structure 100 further includes a control member 50. The control member 50 is electrically connected to the driving mechanism 40, and the control member 50 is used to control the driving mechanism 40 to drive the clamping mechanism 21 to open or clamp.

[0075] Specifically, the control member 50 can be a button box, and buttons for controlling the opening or clamping of the clamping mechanism 21 are provided on the button box.

[0076] In this way, the clamping and welding structure 100 of the present application can control the opening and clamping of the clamping mechanism 21 with one key, which is more intelligent and improves the user experience.

[0077] The above embodiments only represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
