[0002] During the development of new energy vehicles, it is necessary to conduct multiple sample trials on the battery lower box body. During the trial, an aluminum alloy frame needs to be fixed on a jig, then a water-cooled plate is placed on the aluminum alloy frame, and then the water-cooled plate and the aluminum alloy frame are fixedly connected together by a flow drill screw process to form a battery lower box body. After that, the battery lower box body sample can be detached from the jig. The existing jig includes a base, a workpiece clamping mechanism, and a support mechanism. The workpiece clamping mechanism can fix the aluminum alloy frame on the base, and the base supports the aluminum alloy frame.

[0032] The lower battery box is an important component of a battery, which is designed to improve the space utilization rate, sealing effect of the battery pack, and achieve a better thermal management effect. The lower battery box bears the mass of the entire battery pack as well as its own mass, and withstands external impacts, making it an important safety structural part of electric vehicles. During the development of new energy vehicles, it is necessary to conduct multiple sample trials on the lower battery box. During the trial production, the aluminum alloy frame needs to be fixed on the fixture, and then the water-cooled plate is placed on the aluminum alloy frame. Subsequently, the flow drill screw process is used to fixedly connect the water-cooled plate and the aluminum alloy frame to form the lower battery box. After that, the lower battery box sample can be detached from the fixture. With the gradual increase in product types, the acceleration of product updates, and the shortening of the sample development cycle, the efficiency requirements for sample trial production are getting higher and higher. Currently, the fixtures for the lower battery box need to be made separately, and each type of lower battery box sample corresponds to a fixture. Therefore, fixtures need to be made separately for various lower battery boxes, which affects the efficiency of sample trial production.

[0033] Referring to Figures 1 to 5 , the fixture for the lower battery box according to the embodiment of the present invention includes a base 100, a workpiece clamping mechanism 200, and a support mechanism 300. The base 100 is provided with a supporting surface 110 arranged in the horizontal direction; the workpiece clamping mechanism 200 is arranged on the supporting surface 110; the support mechanism 300 is arranged on the supporting surface 110, and the support mechanism 300 is provided with a workpiece support portion 301, and the position of the workpiece support portion 301 can be adjusted horizontally relative to the supporting surface 110.

[0034] When the fixture is in use, according to the shaping requirements of different types of workpieces, the horizontal position of the workpiece support portion 301 of the support mechanism 300 can be adjusted so that when the workpiece is placed on the supporting surface 110 of the base 100, the workpiece support portion 301 can support the raised thin plate shape on the workpiece. Then, the workpiece clamping mechanism 200 is used to fix the workpiece, and the subsequent assembly process can be carried out; since the horizontal position of the workpiece support portion 301 of the support mechanism 300 can be adjusted to adapt to different types of workpieces, the fixture can be commonly used for different types of workpieces, thereby reducing the trial production cost and improving the trial production efficiency.

[0035] Specifically, the base 100 is in the shape of a plate body, and the supporting surface 110 is the upper side surface of the base 100. It can be imagined that the base 100 can also be in other shapes, such as a solid square or a hollow square, etc., as long as there is a supporting surface 110.

[0036] In an embodiment, nine supporting mechanisms 300 are provided. Since the raised thin plate shape of the workpiece has a large area or a large number of them, the raised thin plate shape can be supported by a plurality of supporting mechanisms 300 respectively, so that the overall supporting effect on the workpiece is better, meeting the actual use requirements. It can be imagined that the number of the supporting mechanisms 300 can also be other numbers, such as two, three, four or more, and those skilled in the art can specifically configure according to actual needs.

[0037] In an embodiment, the supporting mechanism 300 includes a rotating shaft member 310 and a supporting component 302. The rotating shaft member 310 is disposed on the supporting surface 110, and the axis of the rotating shaft member 310 is vertically arranged. The supporting component 302 is movably connected to the rotating shaft member 310 and can rotate about the rotating shaft member 310, and the supporting component 302 can slide relative to the rotating shaft member 310. By the supporting component 302 can rotate relative to the rotating shaft member 310, and the supporting component 302 can slide relative to the rotating shaft member 310, it is realized that the supporting portion 301 of the workpiece can adjust its position almost arbitrarily on the supporting surface 110, and the adjustment flexibility is better.

[0038] In an embodiment, the supporting component 302 includes a connecting member 320 and a supporting structure 330. The connecting member 320 is provided with a first strip-shaped hole 321. The rotating shaft member 310 passes through the first strip-shaped hole 321 and can slide along the first strip-shaped hole 321. The connecting member 320 can rotate about the rotating shaft member 310. The supporting structure 330 is disposed on the connecting member 320, and the upper end of the supporting structure 330 is provided with a workpiece supporting portion 301. The connecting member 320 can rotate about the rotating shaft member 310 through the first strip-shaped hole 321, and the connecting member 320 can slide through the first strip-shaped hole 321, so that the supporting component 302 can slide relative to the rotating shaft member 310, thereby being able to freely adjust the position of the workpiece supporting portion 301 on the horizontal plane. The position adjustment of the workpiece supporting portion 301 is relatively flexible, and the adjustment structure is relatively simple and easy to implement.

[0039] Specifically, the rotating shaft member 310 is a screw. When the screw is tightened, the connecting member 320 can be locked and fixed to the base 100, and at this time, the position of the workpiece supporting portion 301 is fixed; when the screw is loosened, the connecting member 320 can rotate relative to the screw, and the screw can slide along the strip-shaped hole, so as to freely move the position of the workpiece supporting portion 301 within the circumferential range. It can be imagined that the rotating shaft member 310 can also be an ordinary rotating shaft, and a limiting block is provided at the upper end of the rotating shaft, and the limiting block is used to limit the upward movement of the connecting member 320.

[0040] It is conceivable that the support assembly 302 can also be other structures. For example, the rotating shaft member 310 is directly rotatably connected to the base 100. The rotating shaft member 310 is provided with a sliding hole, and the support assembly 302 is provided with a sliding rod. The sliding rod slidably penetrates through the sliding hole in the horizontal direction. At this time, the support assembly 302 can also rotate through the rotating shaft member 310 and horizontally slide relative to the rotating shaft member 310, thereby adjusting the horizontal position of the workpiece support portion 301.

[0041] It is conceivable that the support mechanism 300 can also be a support block. A magnet is provided at the bottom of the support block, and the base is made of iron. The support block is installed on the bearing surface 110 by means of magnetic attraction cooperation, and the position of the support mechanism 300 can be adjusted on the bearing surface 110.

[0042] In the embodiment, the connecting member 320 is a rod body, the first elongated hole 321 extends along the length direction of the rod body, and the support structure 330 is located at one end of the rod body. The above-mentioned rod body can save materials to a large extent during production, and the range of horizontal adjustment of the workpiece support portion is large. It can be understood that in some other embodiments, the support structure 330 can also be located at other positions of the rod body, and those skilled in the art can configure it according to actual needs.

[0043] It is conceivable that the connecting member 320 can also be in the shape of a plate or other shapes, as long as it can rotate around the rotating shaft member 310 and slide relative to the rotating shaft member 310. The connecting member 320 in this embodiment is a straight rod body. It can be understood that in some other embodiments, the connecting member 320 can also be a special-shaped rod body, such as a right-angled rod body, an obtuse-angled rod body, etc.

[0044] Specifically, the first elongated hole 321 is a countersunk hole, which can accommodate the head of the screw to be countersunk.

[0045] In the embodiment, the support structure 330 includes a base member 331, a support member 332, and a support locking member 333. The base member 331 is connected to the connecting member 320. The support member 332 is vertically movably arranged on the base member 331. The support locking member 333 is arranged between the base member 331 and the support member 332 and can lock or unlock the position of the support member 332 relative to the base member 331. The upper end of the support member 332 forms the workpiece support portion 301. The above structure can adapt to support raised thin plate shapes of different heights by adjusting the height of the upper end of the support member 332, further improving the versatility of the fixture.

[0046] Specifically, the base member 331 is provided with threaded holes in the vertical direction, and the support member 332 is provided with stud portions. The stud portions are threadedly connected to the threaded holes, so that the support member 332 can move vertically relative to the base member 331, and the supporting force of the support member 332 can be greater without causing the support member 332 to slip. The support locking member 333 is a screw penetrating the side wall of the threaded hole. When the screw is tightened, it can abut against the stud portion to limit the movement of the support member 332 relative to the base member 331, that is, lock the position of the support member 332; when the screw is loosened, the support member 332 is allowed to move relative to the base member 331.

[0047] It can be imagined that the support member 332 can also move vertically relative to the base member 331 through other structures. For example, the base member 331 is provided with guide posts, and the support member 332 is provided with guide holes, and the guide posts are slidably matched with the guide holes; the support locking member 333 can also be a bolt. At this time, a plurality of bolt holes are arranged vertically on both the base member 331 and the support member 332, and the height of the support member 332 is adjusted by inserting bolts into different bolt holes; or the base member 331 is provided with stud portions in the vertical direction, and the support member 332 is provided with threaded holes, and the stud portions are threadedly connected to the threaded holes, so that the support member 332 can move vertically. At this time, the support locking member 333 is a screw penetrating the side wall of the threaded hole.

[0048] It can be imagined that the support mechanism 300 can also be adjusted in position on the supporting surface 110 in other ways. For example, the support mechanism 300 includes an intermediate frame and a support structure 330. The intermediate frame is slidably connected to the base 100 left and right through slide rails and sliders, and the support structure 330 is slidably connected to the intermediate frame front and back through slide rails and sliders. And between the intermediate frame and the base 100, the relative position can be locked by screws. When the screws are tightened, the relative position of the intermediate frame and the base 100 is locked, and when the screws are loosened, the relative position of the intermediate frame and the base 100 is unlocked; similarly, between the support structure 330 and the intermediate frame, the relative position can be locked by screws. When the screws are tightened, the relative position of the intermediate frame and the support structure 330 is locked, and when the screws are loosened, the relative position of the intermediate frame and the support structure 330 is unlocked.

[0049] In the embodiment, eight workpiece clamping mechanisms 200 are provided, which are convenient for clamping and fixing workpieces at multiple positions, and the fixing effect of the fixture is relatively stable. There are two workpiece clamping mechanisms 200 at the front and rear of the base, and two workpiece clamping mechanisms 200 are also provided at the left and right of the base, jointly enclosing a region for placing the lower battery box. It can be imagined that the number of the workpiece clamping mechanisms 200 can also be two, three, four or more. Those skilled in the art can specifically configure according to actual needs. Usually, the workpiece clamping mechanism 200 is used to clamp the outer periphery of the lower battery box, and the distance between two adjacent workpiece clamping mechanisms 200 is close, or can be reasonably selected according to actual needs.

[0050] In an embodiment, the workpiece clamping mechanism 200 includes a lifting assembly 210 and a workpiece pressing block 220. The workpiece pressing block 220 is located above the supporting surface 110 and forms a workpiece clamping position between the workpiece pressing block 220 and the supporting surface 110. The workpiece pressing block 220 is arranged on the base 100 through the lifting assembly 210 and can lift relative to the base 100. The workpiece is placed on the supporting surface 110, and then the lifting assembly 210 can be used to press down the workpiece pressing block 220 to cooperate with the base 100 to clamp and fix the workpiece, and the clamping stability is relatively good.

[0051] In an embodiment, the lifting assembly 210 includes a downward pressing fastener 211 and a jacking member 212. The downward pressing fastener 211 is vertically penetrated through the workpiece pressing block 220. The upper end of the downward pressing fastener 211 is provided with a downward pressing portion for pressing the upper end surface of the workpiece pressing block 220. The lower end of the downward pressing fastener 211 is threadedly connected to the base 100. The upper end of the jacking member 212 is connected to the workpiece pressing block 220, and the lower end of the jacking member 212 abuts against the supporting surface 110. The downward pressing fastener 211 and the jacking member 212 cooperate to keep the workpiece pressing block 220 at a certain height, which is convenient for placing the workpiece on the supporting surface 110 and detaching it from the fixture.

[0052] Specifically, both the downward pressing fastener 211 and the jacking member 212 are bolts. The downward pressing portion is a bolt head. The upper end of the jacking member 212 is threadedly connected to the workpiece pressing block 220. When it is necessary to increase the height of the workpiece pressing block 220, the downward pressing fastener 211 and the jacking member 212 are respectively rotated, so that the length of the downward pressing fastener 211 extending out of the supporting surface 110 is increased, and the length of the jacking member 212 extending out of the workpiece pressing block 220 is increased; when it is necessary to reduce the height of the workpiece pressing block 220, the downward pressing fastener 211 and the jacking member 212 are respectively rotated, so that the length of the downward pressing fastener 211 extending out of the supporting surface 110 is shortened, and the length of the jacking member 212 extending out of the workpiece pressing block 220 is shortened.

[0053] Furthermore, the workpiece pressing block 220 is provided with a second strip-shaped hole 221. The second strip-shaped hole 221 extends in the horizontal direction. The downward pressing fastener 211 is penetrated through the second strip-shaped hole 221 and can slide along the length direction of the strip-shaped hole. When it is necessary to finely adjust the position of the workpiece pressing block 220, the workpiece pressing block 220 can be moved. At this time, the downward pressing fastener 211 slides along the length direction of the second strip-shaped hole 221, so as to allow fine adjustment of the position of the workpiece pressing block 220 within the range of the second strip-shaped hole 221 to meet the clamping position requirements of the workpiece.

[0054] It can be imagined that the lifting assembly 210 can also be other structures. For example, the lifting assembly 210 includes a stud and two nuts. The stud is penetrated through the workpiece pressing block 220. The two nuts are threadedly connected to the stud and clamp the workpiece pressing block 220. The lower end of the stud is threadedly connected to the base 100, and the height of the workpiece pressing block 220 is adjusted by adjusting the positions of the two nuts.

[0055] It can be imagined that the workpiece clamping mechanism 200 can also be other structures. For example, the workpiece clamping mechanism 200 is an elastic clamp that clamps a part of the workpiece.

[0056] In the embodiment, there are also four positioning structures 400. The positioning structures 400 are arranged on the supporting surface 110. Three of the positioning structures 400 are movably arranged on the base 100 and can be locked or unlocked by the first locking structure 500 to position the positioning structures 400 relative to the base 100. The positioning structures 400 are provided with workpiece positioning parts 401. Before the workpiece is placed on the fixture, the workpiece positioning parts 401 of the positioning structures 400 need to align the workpiece first. Some or all of the positioning structures 400 are movable, which is convenient for adjusting the positions of the positioning structures 400 according to the needs of the workpiece and then locking them, so as to adapt to the alignment requirements of different workpieces and have better versatility.

[0057] Specifically, the workpiece positioning part 401 is a positioning pin column, and positioning holes are provided on the workpiece. The positioning pin column can be replaced according to the actual size of the positioning holes of the workpiece to facilitate the insertion and positioning of the positioning pin column and the positioning holes. It can be understood that the workpiece positioning part 401 can also be other structures, such as positioning baffles or positioning blocks, etc.

[0058] It can be understood that the number of the positioning structures 400 can be two, three or more, and some or all of the positioning structures 400 can be movably arranged.

[0059] In the embodiment, there are four positioning structures 400, and all the positioning structures 400 are arranged in the left - right direction. One of the positioning structures 400 is fixedly arranged, and the remaining positioning structures 400 are slidably connected to the base 100 in the left - right direction. The above - mentioned positioning structures 400 meet the positioning requirements of the battery lower box body and have good use effects.

[0060] Specifically, the positioning structure 400 is slidably connected to the base 100 through a slide rail - slider structure. The supporting surface 110 is provided with slide rails in the left - right direction, and the positioning structure 400 is provided with sliders, and the sliders are slidably connected to the slide rails. And limit blocks are arranged at the left and right ends of the slide rails to limit the sliding range of the positioning structure 400 in the left - right direction and prevent the positioning structure 400 from slipping out of the slide rails. It can be imagined that the positioning structure 400 can also be movably connected to the base 100 through a guide post - guide sleeve structure, that is, guide posts are arranged on the base 100 in the left - right direction, and the positioning structure 400 is provided with guide sleeves, and the guide sleeves are slidably sleeved on the guide posts.

[0061] Specifically, the first locking structure 500 is a screw, which is threadedly connected to the slider and can abut against or release the slide rail to achieve locking or unlocking. It can be imagined that the first locking structure 500 can also be a rotating shaft and a semi-circular friction block. The friction block is rotatably connected to the positioning structure 400 through the rotating shaft. When the friction block rotates to abut against the base 100, the positioning structure 400 is locked. When the friction block rotates to not contact the base 100, the positioning structure 400 is unlocked; or the first locking structure 500 is a bolt, and the bolt is slidably installed vertically on the positioning structure 400, and there are multiple pin holes arranged in the left-right direction on the base 100. When the bolt is inserted into a certain pin hole, the positioning structure 400 is locked at a certain position; when the bolt is pulled out, the positioning structure 400 is allowed to slide.

[0062] In the embodiment, the positioning structure 400 includes a lower positioning block 410, an upper positioning block 420, and an adjustment driving member 430. The lower positioning block 410 is slidably connected to the base 100 in the left-right direction. The upper positioning block 420 is slidably arranged on the lower positioning block 410 in the front-back direction. The adjustment driving member 430 is arranged between the upper positioning block 420 and the lower positioning block 410 and is used to drive the upper positioning block 420 to move back and forth relative to the lower positioning block 410. The upper positioning block 420 is provided with a positioning post 440, and the positioning post 440 forms a workpiece positioning portion 401. With the above structure, the adjustment driving member 430 can drive the upper positioning block 420 to finely adjust the position back and forth relative to the lower positioning block 410 to adapt to the actual positioning requirements of the workpiece, and the versatility is relatively good.

[0063] Specifically, the upper positioning block 420 and the lower positioning block 410 are slidably connected through a dovetail groove structure. The adjustment driving member 430 is a screw rod, and the screw rod is rotatably installed on the lower positioning block 410 and is threadedly connected to the upper positioning block 420.
