Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a side plate self-centering clamp. Background Art

[0002] The whole line equipment of battery modules is usually expensive. When the production quantity of a single module product is large, the cost performance of the whole line equipment is more prominent. However, when there are many product types and the production quantity of a single product is relatively small, the equipment needs to frequently replace the fixture to switch between different modules. In this working situation of frequent switching between different products, higher requirements are placed on the equipment accuracy and rapid changeover.

[0003] In the past, in battery module production equipment, the working method for clamping and positioning the side panels of the battery modules was to position the side panels on one side after gluing them, and then adjust the screws on the other side to fix them in the appropriate position, and then tighten them with a cylinder. Then, the side panel grabbing mechanism was adjusted according to the changed side panel positioning center, and after adjusting to the new center position, the side panel was grabbed and produced. This method requires adjustment of two mechanisms according to different side panel sizes, namely, the positioning mechanism after gluing the side panel and the side panel grabbing mechanism. This adjustment method is relatively cumbersome and complicated. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0038] Embodiment 1:

[0039] This embodiment provides a side panel self-centering fixture, comprising:

[0040] Base 1;

[0041] The X-axis centering adjustment mechanism comprises two movable supports 2 and a driving assembly 3 for driving the two movable supports 2 to move synchronously toward each other along the X-axis;

[0042] An X-direction clamping mechanism 4 is mounted on the movable support 2 and is used for clamping in the X direction;

[0043] A Y-direction clamping mechanism 5 is installed on the base 1 and is located between the two movable supports 2. The Y-direction clamping mechanism 5 is used for Y-direction clamping;

[0044] The two movable support members 2 are respectively provided with a clamping reference surface A and a clamping reference surface B which are symmetrically arranged with respect to the center of the X-direction centering adjustment mechanism.

[0045] In this solution, the X direction may be the length direction of the side plate and the length direction of the side plate self-centering fixture, and the Y direction may be the width direction of the side plate and the width direction of the side plate self-centering fixture.

[0046] like Figure 2 As shown, the X-direction clamping mechanism 4 is installed on one of the movable support members 2, and the other movable support member 2 has an abutting surface; when it is necessary to clamp both ends of the side plate in the X direction, the X-direction clamping mechanism 4 moves toward the other movable support member, at which time, one end of the side plate abuts against the X-direction clamping mechanism 4, and the other end of the side plate abuts against the abutting surface on the movable support member 2;

[0047] The clamping reference plane A is the abutting surface on the movable support 2, and the clamping reference plane B is located on the movable support 2 on which the X-axis clamping mechanism 4 is installed. The clamping reference plane B can be set manually so that the clamping reference plane A and the clamping reference plane B are symmetrical about the center of the X-axis centering adjustment mechanism, and the clamping reference plane B is on the clamping moving path of the X-axis clamping mechanism 4; when the X-axis clamping mechanism 4 clamps the side plate, the clamping surface of the X-axis clamping mechanism 4 coincides with the clamping reference plane B.

[0048] The center of the X-axis centering adjustment mechanism mentioned above can be as follows: Figure 2 The center line shown is the center of the bidirectional screw module when the driving mechanism of the X-axis centering adjustment mechanism is a bidirectional screw module.

[0049] When the side panel is changed, it is necessary to first adjust the distance between the two movable support members 2 according to the X-direction length of the side panel, so that the distance between the reference plane A and the reference plane B is equal to the X-direction length of the side panel. Then, the subsequent side panels of the same length specification can always remain centered after being clamped by the X-direction clamping mechanism 4.

[0050] It can be seen from this embodiment that by adjusting the two movable support members 2 to move synchronously toward each other in the X direction, the clamping reference plane A and the clamping reference plane B corresponding to the two ends of the side plate in the X direction are simultaneously close to or away from the center line, and then the X-direction clamping mechanism 4 and the Y-direction clamping mechanism 5 fix the side plate, so that the X-direction center position of the side plate remains unchanged, the reference for center positioning is improved, and the situation of slow change and low efficiency when clamping side plates of different lengths is avoided, which has universality;

[0051] The Y-direction clamping mechanism 5 facilitates clamping and positioning of the side plate in width, and further positioning in the width direction.

[0052] In addition, there can also be two X-direction clamping mechanisms 4, which are respectively located on two movable supports 2. The clamping reference plane A and the clamping reference plane B can be manually set so that the clamping reference plane A and the clamping reference plane B are symmetrical about the center of the X-direction center adjustment mechanism. When the two X-direction clamping mechanisms 4 are clamped, the two clamping surfaces coincide with the clamping reference plane A and the clamping reference plane B respectively.

[0053] Embodiment 2:

[0054] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0055] Two clamping stations are arranged between the two movable supports 2 along the Y direction, and there are two X-direction clamping mechanisms 4 and two Y-direction clamping mechanisms 5, and each clamping station is provided with an X-direction clamping mechanism 4 and a Y-direction clamping mechanism 5;

[0056] The clamping station includes a first clamping surface for cooperating with the X-direction clamping mechanism 4 for clamping and a second clamping surface for cooperating with the Y-direction clamping mechanism 5 for clamping, and the first clamping surface is the clamping reference surface A.

[0057] like Figure 1 As shown, the two clamping stations mean that the side panel self-centering clamp can clamp two side panels at the same time.

[0058] It can be seen from the present embodiment that after the adjustment of the X-axis centering adjustment mechanism is completed, for processing the side panel of this size, it is only necessary to clamp and release the side panel through the X-axis clamping mechanism 4 and the Y-axis clamping mechanism 5. Therefore, by setting two clamping stations in the Y-axis direction, the efficiency of side panel clamping and side panel processing is effectively improved. That is, when the side panel is processed at the clamping station on one side, the side panel can be clamped at the clamping station on the other side, and vice versa, thereby reducing the waiting time of the side panel processing equipment and improving the processing efficiency.

[0059] Embodiment 3:

[0060] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0061] The base 1 is also provided with a first scale 6 for measuring the moving distance of the movable support 2 in the X direction;

[0062] Wherein, the first scale 6 can be fixedly connected to the base 1 by bolts;

[0063] At the same time, in addition to using the first scale 6, a device such as a miniature laser rangefinder for detecting the distance between the two movable support members 2 and displaying the value may also be used.

[0064] It can be seen from the present embodiment that, through the setting of the first scale 6, based on the reading on the first scale 6, it is convenient to adjust the distance between the two movable supports 2 to the length dimension of the side panel, and then accurately position the side panel X upward through the X-direction clamping mechanism 4 to ensure that the center line of the side panel X upward coincides with the center line of the clamp, thereby ensuring the accuracy of the center positioning.

[0065] Embodiment 4:

[0066] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0067] It also includes a fixed support member 7, which is installed between the two movable support members 2;

[0068] The fixed support member 7 and the base 1 may be connected by bolts;

[0069] At the same time, there may be two fixed support members 7 , and the Y-axis clamping mechanism 5 is located between the two fixed support members 7 , and the two fixed support members 7 improve the supporting effect.

[0070] It can be seen from the present embodiment that, by setting the fixed support member 7, it is convenient to support the central part of the side panel, thereby ensuring the flatness of the side panel when clamped, and avoiding center positioning deviation caused by sinking of the central part when processing the side panel, especially the longer side panel in the length direction, to avoid affecting the accuracy.

[0071] Embodiment 5:

[0072] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0073] The driving assembly 3 includes a bidirectional screw module 30 and a driving member 31 for driving the bidirectional screw module 30 to rotate;

[0074] The driving member 31 may be a hand wheel, a handle or a knob, etc., which can be used to cause the bidirectional screw module 30 to rotate;

[0075] At the same time, the bidirectional screw module 30 includes two sections of screws with reverse thread structures, and the screws are arranged between the two clamping stations, so that the movable support 2 provides a better clamping effect on the side panels in the two clamping stations, and the fixed support 7 is provided with a through hole for the screw to pass through, which is convenient for installation.

[0076] It can be seen from this embodiment that the movable support 2 is adjusted by using a bidirectional screw module 30 to ensure that the two movable support members 2 move the same distance, avoiding deviations that would lead to center positioning deviations; and the driving member 31 uses a hand wheel, which has a simple structure and is easy to operate.

[0077] Embodiment 6:

[0078] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0079] A linear rail assembly 8 is provided on the base 1;

[0080] Wherein, the movable support member 2 is slidably connected to the linear rail assembly 8;

[0081] At the same time, there are two linear rail assemblies 8, which are respectively arranged at the two ends of the movable support 2, so as to further improve the stability;

[0082] In addition to the linear rail assembly 8, a structure such as a guide rod or a roller slide groove structure can also be used to allow the movable support member 2 to slide along a straight line on the base 1.

[0083] It can be seen from the present embodiment that by providing the linear rail assembly 8, the stability of the movable support member 2 in the X-direction movement is improved and the linearity during sliding is ensured, thereby ensuring the X-direction clamping of the side plate.

[0084] Embodiment 7:

[0085] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0086] The X-direction clamping mechanism 4 includes a length clamping plate 40 and an X-direction clamping cylinder 41 for driving the length clamping plate 40 to move along the X-direction;

[0087] Among them, the X-axis clamping cylinder 41 is fixed to the movable support 2 by bolts, so that it can move with the movable support 2 to avoid using an excessively large cylinder stroke;

[0088] At the same time, in addition to using the X-axis clamping cylinder 41, components such as electric push cylinders or hydraulic cylinders that can be used to push the length clamping plate 40 to clamp the side plate can also be used.

[0089] It can be seen from this embodiment that the side plate is accurately positioned in the X direction by the length clamping plate 40 by adopting a cylinder-driven method, which has high efficiency, simple structure and convenient control.

[0090] Embodiment 8:

[0091] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0092] The Y-direction clamping mechanism 5 comprises a width clamping plate 50 and a Y-direction clamping cylinder 51 for driving the width clamping plate 50 to move along the Y-direction;

[0093] The Y-axis clamping cylinder 51 is fixed on the base 1 by bolts.

[0094] At the same time, in addition to using the Y-axis clamping cylinder 51, components such as electric push cylinders or hydraulic cylinders that can be used to push the width clamping plate 50 to clamp the side plates can also be used.

[0095] It can be seen from this embodiment that the side plate is accurately positioned in the Y direction by the width clamping plate 50 through the cylinder drive, which has high efficiency, simple structure and convenient control.

[0096] Embodiment 9:

[0097] This embodiment provides a side panel self-centering fixture, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0098] The Y-direction clamping mechanism 5 further includes a second scale 9 for measuring the installation distance of the Y-direction clamping cylinder 51 in the Y-direction;

[0099] Among them, the second scale 9 can be fixedly connected to the base 1 by bolts, and the Y-axis clamping mechanism 5 also includes a base for installing the Y-axis clamping cylinder 51, and slots are provided on both sides of the base. A plurality of mounting holes are provided on the base 1 along the Y direction, and a pointer corresponding to the second scale 9 is provided on the side of the base.

[0100] It can be seen from this embodiment that by providing the second scale 9, it is convenient to adjust the installation position of the Y-direction clamping cylinder 51, so as to avoid the situation that the distance between the width clamping plate 50 and the second clamping surface after the maximum extension distance of the output end is less than the width of the side plate, or the distance between the output end and the second clamping surface after the minimum retraction distance is greater than the width of the side plate, resulting in the inability to clamp the side plate in the Y direction;

[0101] At the same time, multiple mounting holes facilitate coarse adjustment of the mounting position, slot holes facilitate fine adjustment of the mounting position, and the pointer improves the accuracy of the adjustment.

[0102] The working principle of the utility model is: when changing the type, the side panel is supported by the middle fixed support member 7, and based on the X-direction length of the side panel, the hand wheel is adjusted to drive the bidirectional screw module 30 to rotate, thereby driving the two movable support members 2 to move synchronously along the linear rail assembly 8, so that the X-direction distance between the clamping reference surface A and the clamping reference surface B is equal to the X-direction length of the side panel; then the width clamping plate 50 is pushed by the Y-direction clamping cylinder 51 to cooperate with the second clamping surface for clamping, and the length clamping plate 40 is pushed by the X-direction clamping cylinder 41 to cooperate with the first clamping surface for clamping, and then, when the side panel is grabbed, the X-direction clamping cylinder 41 and the Y-direction clamping cylinder 51 are reset, and the side panel grabbing mechanism grabs it; when it is necessary to replace side panels of different sizes and models, the above steps are repeated, and the above method enables the length center lines of different types of side panels to maintain the same position as the center line of the fixture, so that the subsequent side panel grabbing mechanism does not need to be adjusted, thereby improving efficiency.

[0103] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
