[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0040] Please combine Figures 1 to 3 As shown, the present application proposes a fixing device for fixing a workpiece to be processed, wherein the workpiece to be processed includes an upper cover and a bottom shell, and the fixing device includes a base, a fixing component 1, a pressure cover component 2 and a driving component 3, wherein the fixing component 1 is connected to the base, and the fixing component 1 is provided with a fixing groove 11, and the fixing groove 11 is used to place the workpiece to be processed, and the pressure cover component 2 is connected to the base, and the pressure cover component 2 is provided with a movable pressing member 24, and the pressing member 24 is used to press the upper cover of the workpiece to be processed; the driving component 3 is connected to the base, and is used to move the pressing member 24; wherein the pressure cover component 2 has a first state in which the pressing member 24 presses the upper cover and a second state in which the pressing member 24 releases the upper cover; in the first state, the pressing member 24 is manually moved to abut against the upper cover, so that the pressing member 24 presses the upper cover by its own gravity; in the second state, the driving component 3 drives the pressing member 24 to move, so that the pressing member 24 leaves the upper cover.

[0041] In this embodiment, the fixing groove 11 in the fixing component 1 is used to place the workpiece to be processed. After the upper cover and the bottom shell of the workpiece to be processed are combined, they are placed in the fixing groove 11. The pressure cover component 2 is provided with a movable pressing member 24. The pressing member 24 can be moved to the upper cover manually. After releasing the hand, the pressing member 24 presses the upper cover under the action of gravity, so that the upper cover and the bottom shell are pressed tightly, that is, the pressure cover component 2 enters the first state of pressing the upper cover, so as to prevent the upper cover and the bottom shell from being separated when the fixing component 1 transports the workpiece to be processed.

[0042] It is understandable that the cross-sectional shape and size of the fixing groove 11 are comparable to the cross-sectional shape and size of the bottom shell, that is, the bottom shell may abut against the side wall of the fixing groove 11 to prevent the bottom shell from shaking in the fixing groove 11. However, due to the low placement accuracy of the workpiece to be processed in the fixing groove 11, the workpiece to be processed may be biased upward or downward in the fixing groove 11. If the upper cover is pressed down according to the preset stroke by the electric driving fixing device, the upper cover may be subjected to too much or too little pressure, resulting in damage to the workpiece to be processed or insufficient tightness of the upper cover and the bottom shell. Therefore, by manually moving the pressing member 24, the pressing member 24 presses the upper cover and the bottom shell under the action of gravity, and the pressure on the upper cover remains constant. The pressure on the upper cover will not change due to the different positions of different workpieces to be processed in the fixing groove 11, so that the degree of compression of the upper cover and the bottom shell meets the requirements. The pressure on the upper cover can be adjusted by changing the mass of the pressing member 24 so that the pressure on the upper cover is within a suitable range, thereby ensuring that the degree of compression of the upper cover and the bottom shell is within a suitable range. When the workpiece does not need to be pressed, the driving assembly 3 will drive the pressing member 24 to leave the upper cover, that is, the pressing cover assembly 2 enters the second state of releasing the upper cover, so as to improve the efficiency of the pressing member 24 in releasing the upper cover, saving labor costs and processing efficiency.

[0043] In an embodiment of the utility model, the pressure cover assembly 2 includes a first mounting member 21 and a second mounting member 22, the first mounting member 21 is connected to the base and is provided with a first slide rail 211, the second mounting member 22 is movably connected to the first mounting member 21 and is provided on the first slide rail 211, the second mounting member 22 is provided with a second slide rail 221, and the pressing member 24 is movably provided on the second slide rail 221; wherein, the extension direction of the first slide rail 211 and the extension direction of the second slide rail 221 are vertically arranged.

[0044] In this embodiment, the second mounting member 22 is moved on the first slide rail 211, and the pressing member 24 is moved on the second slide rail 221 to adjust the position of the pressing member 24 so that it can be accurately pressed on the upper cover. Optionally, the first mounting member 21 includes a first mounting plate and a second mounting plate arranged at an angle, the first mounting plate is detachably connected to the base and arranged parallel to the surface of the base, the surface of the base is arranged in a horizontal plane, the second mounting plate is arranged perpendicular to the first mounting plate, the first slide rail 211 is arranged on one side of the second mounting plate, and is extended in the vertical direction, and a support plate is also connected to the side of the first mounting plate facing away from the first slide rail 211, and the support plate is simultaneously connected to the first mounting plate and the second mounting plate to ensure the stability of the first mounting plate and the first slide rail 211. The second mounting member 22 can be set in a plate shape, and a slider is provided on one side of the second mounting member 22. The second mounting member 22 is slidably connected to the first slide rail 211 through the slider. The second mounting member 22 is provided with a second slide rail 221 on the side facing away from the slider, and the pressing member 24 is slidably set on the second slide rail 221 through the slider.

[0045] It can be understood that the extension direction of the second slide rail 221 is perpendicular to the extension direction of the first slide rail 211, the extension direction of the first slide rail 211 is the vertical direction, and the extension direction of the second slide rail 221 is in the horizontal plane. At the same time, the fixing assembly 1 is arranged in the extension direction of the second slide rail 221. When manually adjusting the pressing member 24 to the upper cover, the second mounting member 22 needs to be moved along the first slide rail 211 so that the height of the pressing member 24 is slightly higher than the height of the upper cover, and then the pressing member 24 is moved along the second slide rail 221 so that the pressing assembly moves to the top of the upper cover, and then the second mounting member 22 moves downward along the second slide rail 221 under the action of its own weight and the weight of the pressing member 24, thereby driving the pressing member 24 to press the upper cover and the bottom shell.

[0046] In an embodiment of the utility model, the driving component 3 includes a first driving member 31 and a first moving block 311. The first driving member 31 is connected to the base, the first moving block 311 is connected to the output end of the first driving member 31, the first moving block 311 is provided with a first inclined surface, and the pressing member 24 is provided with a first rotating roller 243 corresponding to the first inclined surface; in the second state, the first driving member 31 drives the first moving block 311 to approach the first rotating roller 243, and the first inclined surface abuts the first rotating roller 243, so that the pressing member 24 leaves the upper cover.

[0047] In this embodiment, when the pressing member 24 needs to be removed from the upper cover, the first driving member 31 drives the first moving block 311 to move toward the first rotating roller 243, so that the first inclined surface abuts against the first rotating roller 243, and thus the first rotating roller 243 moves along the first inclined surface, thereby driving the pressing member 24 to leave the upper cover. It can be understood that the position of the first moving block 311 is set corresponding to the position of the first rotating roller 243 when the pressing member 24 presses the upper cover.

[0048] Optionally, the driving direction of the first driving member 31 may be a vertical direction, and the first inclined surface may be vertical at an angle of 45° to the horizontal plane.

[0049] In an embodiment of the utility model, the pressing member 24 includes a guide block 242 and a pressing block 241. The guide block 242 is slidably arranged on the second slide rail 221. The pressing block 241 is connected to one end of the guide block 242 close to the fixed component 1. The pressing block 241 is provided with a protruding section for pressing the upper cover. The end of the guide block 242 away from the pressing block 241 is provided with a first rotating roller 243; wherein, the extension direction of the guide block 242 is consistent with the extension direction of the second slide rail 221.

[0050] In this embodiment, the pressing member 24 is composed of a guide block 242 and a pressing block 241. The pressing block 241 is connected to the second slide rail 221 through the guide block 242. The pressing block 241 is provided with a protruding section toward the fixed component 1 for abutting the upper cover. The first rotating roller 243 is provided at one end of the guide block 242 away from the pressing block 241, so that the first moving block 311 and the first rotating roller 243 can cooperate and abut. Optionally, the guide block 242 includes a first block body and a second block body that are arranged in a superimposed manner, one side of the first block body is slidably arranged on the second slide rail 221, the pressing block 241 is connected to one end of the first block body, and the second block body is arranged on the other side of the first block body and is provided with a first rotating roller 243. The first block body can be arranged in an L-shape to increase the connection area between the pressing block 241 and the first block body, thereby improving the stability of the setting of the pressing block 241. The protruding sections may include a plurality of protruding sections which are arranged at intervals and are used to press against the upper cover near the periphery so that the upper cover is subjected to uniform force. The protruding parts of the upper cover can also be avoided between adjacent protruding sections.

[0051] In an embodiment of the utility model, the pressure cover assembly 2 also includes a third mounting member 23 and a locking member 25. The third mounting member 23 is connected to the first mounting member 21. The third mounting member 23 is provided with a third slide rail 231. The locking member 25 is movably provided on the third slide rail 231. The locking member 25 is provided with a locking rod 251. The guide block 242 is provided with a locking hole 222 corresponding to the locking rod 251. The extension direction of the third slide rail 231, the extension direction of the first slide rail 211 and the extension direction of the second slide rail 221 are arranged vertically in pairs.

[0052] In this embodiment, the third mounting member 23 is disposed on a side of the first mounting member 21 facing away from the second mounting member 22. The third mounting member 23 is further provided with a third slide rail 231. The extension direction of the third slide rail 231 is perpendicular to the extension direction of the first slide rail 211 and the extension direction of the second slide rail 221. The locking member 25 is slidably disposed on the third slide rail 231. The locking member 25 can move along the third slide rail 231 to approach or move away from the second mounting member 22, so as to extend the locking rod 251 into the locking hole 222 of the second mounting member 22 or to be pulled out of the locking hole 222.

[0053] It can be understood that at least part of the locking member 25 extends out of the third slide rail 231, the locking rod 251 is arranged on the protruding part of the locking member 25, at least part of the second mounting member 22 extends out of the first slide rail 211, and the locking hole 222 is arranged on the protruding part of the second mounting member 22, so that the locking rod 251 can pass over the first mounting member 21 and penetrate into or exit the locking hole 222. The setting height of the third mounting member 23 is equivalent to the height of the second mounting member 22 when the pressing block 241 presses the upper cover. When the pressing member 24 presses the workpiece to be processed, the locking rod 251 does not extend into the locking hole 222, so that the pressing member 24 can press the workpiece to be processed under the action of gravity. When the pressing member 24 leaves the upper cover, the locking member 25 can move along the third slide rail 231 to approach the second mounting member 22, so that the locking rod 251 extends into the locking hole 222 to limit the movement of the second mounting member 22 along the first slide rail 211, so that when the pressing member 24 completely leaves the upper cover, the pressing member 24 still maintains a certain height to facilitate manual movement of the pressing member 24 for the next pressing.

[0054] Optionally, the third mounting member 23 is arranged in an L-shape to improve the stability of the connection with the first mounting member 21 .

[0055] In one embodiment, the driving assembly 3 includes a second driving member 32 and a second moving block 321, the second driving member 32 is connected to the base, the second moving block 321 is connected to the output end of the second driving member 32, the second moving block 321 is provided with a second inclined surface, and the locking member 25 is provided with a second rotating roller 252 corresponding to the second inclined surface; in the second state, the second driving member 32 drives the second moving block 321 to approach the second rotating roller 252, and the second inclined surface abuts the second rotating roller 252, so that the locking rod 251 passes through the locking hole 222.

[0056] In this embodiment, the locking member 25 is provided with a second rotating roller 252, and the output end of the second driving member 32 is provided with a second moving block 321, and the second moving block 321 is provided with a second inclined surface. When the second driving member 32 drives the second moving block 321 to move toward the second rotating roller 252, so that the second inclined surface abuts against the second rotating roller 252, the second rotating roller 252 will move along the second inclined surface, thereby driving the locking member 25 to approach the second mounting member 22, so that the locking rod 251 extends into the locking hole 222. It can be understood that the position of the second moving block 321 is set corresponding to the position of the second rotating roller 252 when the locking rod 251 does not penetrate the locking hole 222.

[0057] It can be understood that the inclination direction of the second inclined surface is also different from that of the first inclined surface. When the first driving member 31 drives the first moving block 311 to press down, the second lifting member also drives the second moving block 321 to press down, so that the second inclined surface abuts the second rotating roller 252 to drive the locking rod 251 to move toward the locking hole 222. When the pressing block 241 has not completely left the upper cover, the locking rod 251 extends into the locking hole 222 and limits the second mounting block from moving along the first slide rail 211, preventing the second mounting block and the locking member 25 from falling to the end of the first slide rail 211 after leaving the upper cover, so that the pressing block 241 can still maintain a height close to the notch of the fixing groove 11 after releasing the upper cover. When the fixing assembly 1 is reloaded, it is only necessary to manually move the locking member 25 along the third slide rail 231 to pull the locking rod 251 out of the locking hole 222, and then manually move the pressing block 241 to the upper cover again. The pressing block 241 presses the upper cover under the action of gravity, thereby improving the convenience of manually moving the pressing block 241. It can be understood that the locking hole 222 is extended along the extension direction of the second slide rail 221, so that after the locking rod 251 is inserted into the locking hole 222, the second mounting member 22 can still move along the second slide rail 221 until the pressing block 241 completely leaves the upper cover. At the same time, the locking hole 222 also has a certain height, so that when the height of the second mounting member 22 is different, the locking rod 251 can still be inserted into the locking hole 222.

The fixing member 13 and the stopper 14 are both connected to the base 12, so that the fixing assembly 1 can be assembled and disassembled through modularization. Two stoppers 14 are movably arranged on both sides of the fixing groove 11, and are used to clamp and fix the bottom shell located in the fixing groove 11 to prevent the bottom shell from shaking during welding.

[0060] Optionally, the fixing member 13 includes a supporting portion 131 and a fixing portion 132. The supporting portion 131 is connected to the base 12 and encloses with the base 12 to form a through cavity 133.
