Sliding sleeves are movably sleeved on the two movable rods, and the sliding sleeves are fixedly connected by a traction rod. A rotating seat is hinged on the fixed seat.

[0004] However, existing technologies still have shortcomings:

[0005] With the above setup, after placing the lithium battery to be welded in the welding placement slot, it is necessary to manually adjust the four hand levers to move the mounting plates to limit the lithium battery. Then, by tightening the eight locking bolts, the four mounting plates are limited. First, manual adjustment makes it difficult to center the lithium battery, affecting subsequent welding processing. Second, the above setup is cumbersome to operate after clamping, affecting the processing efficiency of the device. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a positioning fixture for lithium battery processing, which solves the problem in the prior art that requires manual adjustment of four hand levers to move the mounting plate to limit the lithium battery's position. Manual adjustment makes it difficult to achieve centered positioning of the lithium battery, affecting subsequent welding processes.

[0007] To achieve the above objectives, this utility model proposes a positioning fixture for lithium battery processing, including a processing table. A welding placement groove is formed on the processing table, and a turntable is rotatably disposed within the welding placement groove. Four guide grooves are symmetrically arranged on the processing table, and clamping plates are slidably disposed on each guide groove. A support rod is fixedly disposed on each clamping plate, and the support rod extends through the guide groove into the processing table. A threaded sleeve is fixedly disposed at the end of the guide groove extending into the processing table. A transverse bidirectional screw and a longitudinal bidirectional screw are rotatably disposed within the processing table, and two sets of threaded sleeves are symmetrically disposed on the transverse bidirectional screw and the longitudinal bidirectional screw, respectively. A second motor and a first motor are fixedly disposed on the side of the processing table; the second motor is fixedly connected to the longitudinal bidirectional screw, and the first motor is fixedly connected to the transverse bidirectional screw.

[0008] As a further embodiment of this utility model: the turntable is disposed in the middle of the processing table.

[0009] As a further embodiment of this utility model: a slider and a connecting rod are fixedly provided between the support rod and the clamping plate.

[0010] As a further embodiment of this utility model: the slider is slidably disposed on the guide groove, the support rod is fixedly connected to the slider, one end of the connecting rod is fixedly connected to the slider, and the other end is fixedly connected to the clamping plate.

[0011] As a further embodiment of this utility model, a protective pad is fixedly provided on the clamping plate.

[0012] As a further embodiment of this utility model: the height of a pair of support rods disposed on the transverse bidirectional screw is greater than the height of a pair of support rods disposed on the longitudinal bidirectional screw.

[0013] As a further embodiment of this utility model: two supports are fixedly provided on the side of the processing table, and the second motor and the first motor are fixedly provided on one of the supports.

[0014] As a further embodiment of this utility model: both the second motor and the first motor are self-locking motors.

[0015] As a further embodiment of this utility model: an adjustment hole is provided in the middle of the processing table, a mounting frame is fixedly installed inside the processing table, a third motor is installed on the mounting frame, and the output shaft of the third motor passes through the adjustment hole and is fixedly connected to the turntable.

[0016] As a further embodiment of this utility model, a protective door is fixedly installed on the processing table.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting up a transverse bidirectional screw and a longitudinal bidirectional screw, both of which are symmetrically equipped with a pair of threaded sleeves, and the threaded sleeves are connected to a clamping plate, the lithium battery can be centered and clamped by setting up a second motor and a first motor to synchronously drive the two motors. At the same time, the two motors are self-locking motors, so after the lithium battery is clamped, there is no need to further limit the clamping plate.

[0019] 2. By setting a turntable on the processing table, and installing a third motor inside the processing table to drive the turntable to rotate, the lithium battery is placed on the turntable. By rotating the turntable, the lithium battery can be easily rotated, thereby adjusting its welding points. Attached Figure Description

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1:

[0027] like Figure 1-4As shown, a positioning fixture for lithium battery processing includes a processing table 1. A welding placement groove 2 is formed on the processing table 1, and a turntable 5 is rotatably disposed within the welding placement groove 2. The turntable 5 is located in the center of the processing table 1 and is used to place the lithium battery to be welded, facilitating subsequent orientation adjustments. Four guide grooves 3 are symmetrically arranged on the processing table 1. Clamping plates 4 are slidably disposed on the guide grooves 3, and support rods 12 are fixedly disposed on the clamping plates 4. Specifically, a slider 17 and a connecting rod 18 are disposed between the support rod 12 and the clamping plates 4. The slider 17 is slidably disposed on the guide groove 3, and the support rod 12 is fixedly connected to the slider 17. One end of the connecting rod 18 is fixedly connected to the slider 17, and the other end is fixedly connected to the clamping plate 4. A protective pad 16 is fixedly disposed on the clamping plate 4. In this embodiment, the protective pad 16 is a rubber pad.

[0028] The support rod 12 extends through the guide groove 3 into the machining table 1. A threaded sleeve 13 is fixedly installed at the end of the guide groove 3 extending into the machining table 1. A transverse bidirectional screw 10 and a longitudinal bidirectional screw 11 are rotatably installed inside the machining table 1. Two sets of threaded sleeves 13 are symmetrically arranged on the transverse bidirectional screw 10 and the longitudinal bidirectional screw 11, respectively. The height of a pair of support rods 12 on the transverse bidirectional screw 10 is greater than the height of a pair of support rods 12 on the longitudinal bidirectional screw 11, to facilitate the rotation of the longitudinal bidirectional screw 11 and the transverse bidirectional screw 10 and prevent interference during operation. A second motor 7 and a first motor 8 are fixedly installed on the side of the machining table 1. The output shaft of the second motor 7 is fixedly connected to the longitudinal bidirectional screw 11, and the output shaft of the first motor 8 is fixedly connected to the transverse bidirectional screw 11. The screw 10 is fixedly connected, and two brackets 9 are fixedly installed on the side of the processing table 1. The second motor 7 and the first motor 8 are both fixedly installed on one bracket 9. When the lithium battery is placed on the turntable 5, the second motor 7 and the first motor 8 are started simultaneously, driving the transverse bidirectional screw 10 and the longitudinal bidirectional screw 11 to rotate synchronously. This allows the pair of threaded sleeves 13 on the transverse bidirectional screw 10 and the pair of threaded sleeves 13 on the longitudinal bidirectional screw 11 to move towards each other until the four clamping plates 4 clamp the lithium battery on the turntable 5. Specifically, the second motor 7 and the first motor 8 are both self-locking motors. After clamping the lithium battery, the transverse bidirectional screw 10 and the longitudinal bidirectional screw 11 remain fixed, that is, there is no need to manually limit the clamping plates 4. A protective door 6 is fixedly installed on the processing table 1 to protect the internal structure of the processing table 1.

[0029] Example 2:

[0030] like Figure 1-4As shown, a positioning fixture for lithium battery processing differs from Embodiment 1 in that an adjustment hole 19 is provided in the middle of the processing table 1, a mounting frame 15 is fixedly installed inside the processing table 1, and a third motor 14 is installed on the mounting frame 15. The output shaft of the third motor 14 passes through the adjustment hole 19 and is fixedly connected to the turntable 5. By starting the third motor 14, the turntable 5 is driven to rotate, thereby realizing the adjustment of the lithium battery welding area.

[0031] Working principle:

[0032] In use, the lithium battery to be welded is placed on the turntable 5. Then, the second motor 7 and the first motor 8 are started simultaneously, driving the transverse bidirectional screw 10 and the longitudinal bidirectional screw 11 to rotate synchronously. This causes the pair of threaded sleeves 13 on the transverse bidirectional screw 10 and the pair of threaded sleeves 13 on the longitudinal bidirectional screw 11 to move towards each other until the four clamping plates 4 clamp the lithium battery on the turntable 5. When the welding position needs to be adjusted, the second motor 7 and the first motor 8 are started, driving the transverse bidirectional screw 10 and the longitudinal bidirectional screw 11 to rotate in opposite directions, thereby releasing the four clamping plates 4 from the lithium battery. Then, the turntable 5 is rotated to adjust the welding point of the lithium battery. After the adjustment is completed, the second motor 7 and the first motor 8 are started to clamp the lithium battery again.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
