Technical Field

[0001] The utility model relates to the field of material clamping, in particular to a clamping claw used for clamping cylindrical materials. Background Art

[0002] When clamping cylindrical materials, especially for battery cells, multiple clamps are often used to grasp them synchronously. Patent No.: 202320953487.X, patent name: A clamp structure for positioning cylindrical batteries, discloses a clamp structure that uses a cylinder to clamp a pair of clamping pieces; if multiple battery cells need to be clamped, multiple clamp structures need to be connected, so multiple cylinders are required to cooperate. The use of multiple cylinders increases the cost and cannot ensure the consistency of the movement of the clamping pieces;

[0003] In summary, how to clamp cylindrical materials has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to realize the clamping of cylindrical materials;

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model is a clamping claw for clamping cylindrical materials, comprising: a fixed part; a lifting part, which is lifted and lowered on the fixed part by a power source, and a guide groove is opened at the center line of the end surface of the fixed part obliquely upward on both sides, and the guide groove is in a V-shaped structure; a horizontal slide rail, which is arranged on the fixed part and located on both sides of the lifting part; a connecting rod arranged oppositely, which is slidably connected with the corresponding horizontal slide rail, and one end of which is provided with a slider located in the guide groove; a plurality of pairs of extension rods arranged oppositely, which are fixedly connected with the corresponding connecting rods; a clamping part, which is arranged at the bottom of each of the extension rods, and the inner side surface of the clamping part is arranged as a concave arc surface;

[0007] A power source is used to realize the lifting and lowering of the lifting part relative to the fixed part. The lifting part rises, driving the relatively arranged sliding block to move inward, causing the relatively arranged connecting rod to move inward synchronously along the corresponding horizontal slide rail, thereby driving the relatively extended rod to approach. Since the inner side surface of the clamping part is arranged as an inwardly concave arc surface, the cylindrical material can be clamped by the relative approach of the two clamping parts, that is, the lifting movement of the lifting part can be converted into the back-to-back or relative movement of the relatively arranged extension rods through the setting of the guide groove.

[0008] In this solution, one power source is used to achieve the clamping of multiple clamping parts, which ensures the synchronous movement of the multiple clamping parts and reduces the cost.

[0009] In order to illustrate the specific structure of the power source, the power source is a cylinder or an electric cylinder or a screw pair; the cylinder body of the cylinder or electric cylinder is hinged to the lug of the fixed part, and the extended end of the cylinder or electric cylinder is connected to the lifting part; or the screw of the screw pair is rotatably fixed on the fixed part, the nut is rotatably connected to the screw, and the nut is rotatably arranged on the lifting part;

[0010] Taking the use of a cylinder as the power source as an example, the retraction of the extended end of the cylinder or the lifting plate realizes the rise of the lifting plate and the clamping of the clamping part, and the extension of the extended end of the cylinder realizes the lowering of the lifting plate and the release of the clamping part.

[0011] In order to increase the service life of the clamping part, the utility model adopts a rubber sleeve on the outer cover of the clamping part;

[0012] The friction between the material and the clamping part is increased by providing the rubber sleeve. In addition, the wear of the clamping part is avoided by providing the rubber sleeve. After the rubber sleeve is worn, only the rubber sleeve needs to be replaced.

[0013] In order to further increase the service life of the clamping part, the utility model adopts the outer side surface of the clamping part to be set as the concave arc surface;

[0014] In this way, when one side of the clamping part or one side of the rubber sleeve is worn, the clamping part can be turned over and connected to the extension rod for continued use. When both sides of the clamping part or the rubber sleeve are worn, they can be replaced.

[0015] In order to realize the connection between the clamping part and the extension rod, the utility model adopts a fixing through hole connected to the extension rod opened at the center of the upper part of the clamping part; an adjustment waist hole is opened at the clamping part and located on both sides of the fixing through hole;

[0016] The connection between the clamping part and the extension rod can be achieved by setting the fixing hole, and the clamping part can be adjusted to a small angle by setting the adjusting waist hole, so that the clamping part can be fixed in a vertical state.

[0017] In order to limit the lifting part to only lift movement, the utility model adopts two limit rods vertically arranged on the end surface of the fixed part, and a limit groove for the lifting part to lift is formed between the two limit rods;

[0018] The two sides of the lifting part are against the corresponding limit rods, so that the lifting part can only perform lifting movement.

[0019] In order to ensure the stability of the clamping part during clamping, the utility model adopts the end surface of the lifting part to open two guide grooves arranged vertically; two pairs of connecting rods arranged vertically, and the sliders at the ends of each pair of connecting rods are located in the same guide groove;

[0020] There are two guide grooves, and each extension rod is provided with a connecting rod arranged up and down. The slider at the end of the connecting rod is placed in the guide groove, and the number of sliders = the number of guide grooves * 2; in this way, during the lifting process of the lifting plate, the approach or distance of the connecting rod is more stable, thereby ensuring the stability of the clamping part during clamping.

[0021] In order to increase the stability of the clamping part during clamping, the utility model adopts negative pressure holes on both sides of the clamping part; one end of the negative pressure hole on one side is connected to the side of the clamping part and the rubber sleeve, and the other end is connected to the inner side of the clamping part and the rubber sleeve; one end of the negative pressure hole on the other side is connected to the side of the clamping part and the rubber sleeve, and the other end is connected to the outer side of the clamping part and the rubber sleeve;

[0022] In this solution, a negative pressure space is formed between the contact surface of the rubber sleeve and the material by connecting the negative pressure device to the negative pressure hole, thereby improving the stability during clamping; a negative pressure hole is also provided on the outer side of the clamping part, and the negative pressure function can also be realized when the clamping part is flipped and fixed.

[0023] The beneficial effects of the utility model are as follows: the utility model is a clamping claw for clamping cylindrical materials, which adopts a power source to realize the lifting and lowering of the lifting part relative to the fixed part. The lifting part rises, driving the relatively arranged sliding block to move inward, causing the relatively arranged connecting rod to move inward synchronously along the corresponding horizontal slide rail, thereby driving the relatively extended rod to approach. Since the inner side surface of the clamping part is arranged as an inwardly concave arc surface, the cylindrical material can be clamped by the relative approach of the two clamping parts, that is, the lifting movement of the lifting part can be converted into the back-to-back or relative movement of the relatively arranged extension rods through the setting of the guide groove. In this way, the clamping of multiple clamping parts can be realized by adopting one power source, which ensures the synchronous movement of multiple clamping parts while reducing the cost.

DETAILED DESCRIPTION

[0031] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0032] like Figure 1-5 As shown, the utility model is a clamping claw for clamping cylindrical materials, comprising: a fixed part 1; a lifting part 2, which is lifted and lowered on the fixed part 1 by a power source 3, and a guide groove 4 is opened at the center line of the end surface of the fixed part 1 obliquely upward on both sides, and the guide groove 4 is a V-shaped structure; a horizontal slide rail 5, which is arranged on the fixed part 1 and is located on both sides of the lifting part 2; a connecting rod 6 arranged oppositely, which is slidably connected with the corresponding horizontal slide rail 5, and one end of which is provided with a slider 7 located in the guide groove 4; a plurality of pairs of extension rods 8 arranged oppositely, which are fixedly connected with the connecting rod 6; a clamping part 9, which is arranged at the bottom of each of the extension rods 8, and the inner side surface of the clamping part 9 is arranged as a concave arc surface 11;

[0033] A power source 3 is used to realize the lifting and lowering of the lifting part 2 relative to the fixed part 1. The lifting part 2 rises, driving the relatively arranged sliding block 7 to move inward, causing the relatively arranged connecting rod 6 to move inward synchronously along the corresponding horizontal slide rail, thereby driving the relatively extended rod 8 to approach. Since the inner side surface of the clamping part 9 is arranged as a concave arc surface 11, the cylindrical material can be clamped by the relative approach of the two clamping parts 9, that is, the lifting movement of the lifting part 2 can be converted into the opposite or relative movement of the relatively arranged extension rod 8 through the setting of the guide groove 4.

[0034] In this solution, one power source 3 is used to achieve the clamping of multiple clamping parts 9, which ensures that the multiple clamping parts 9 move synchronously in opposite directions or relative to each other, while also reducing costs.

[0035] like Figure 1 As shown, in order to illustrate the specific structure of the power source, the utility model adopts the power source 3 as a cylinder; the cylinder body of the cylinder is hinged to the support ear 12 of the fixing part 1, and the extended end of the cylinder is connected to the lifting part 2;

[0036] In this solution, the retraction of the extended end of the cylinder realizes the lifting of the lifting plate 2 and the clamping of the clamping part 9, and the extension of the extended end of the cylinder realizes the lowering of the lifting plate 2 and the release of the clamping part 9.

[0038] The rubber sleeve 10 is provided to increase the friction between the material and the clamping part 9. In addition, the rubber sleeve 10 is provided to avoid the wear of the clamping part 9. When the rubber sleeve 10 is worn, only the rubber sleeve 10 needs to be replaced.

[0039] like Figure 4-5 As shown, in order to further increase the service life of the clamping portion, the utility model adopts the outer side surface of the clamping portion 9 to be set as the concave arc surface 11;

[0040] In this way, when one side of the clamping part 9 or one side of the rubber sleeve 10 is worn, the clamping part 9 can be turned over and connected to the extension rod 8 for continued use. When both sides of the clamping part 9 or the rubber sleeve 10 are worn, they can be replaced.

[0041] like Figure 4-5 As shown, in order to realize the connection between the clamping part and the extension rod, the utility model adopts a fixing through hole 13 connected to the extension rod 8 opened at the center of the upper part of the clamping part 9; an adjusting waist hole 14 is opened at the clamping part 9 and located on both sides of the fixing through hole 13;

[0042] The fixing hole 13 can be provided to connect the clamping part 9 to the extension rod 8 , and the adjusting waist hole 14 can be provided to adjust the clamping part 9 to a small angle, so that the clamping part 9 can be fixed in a vertical state.

[0043] like Figure 1 As shown, in order to limit the lifting part to only lift movement, the utility model adopts two limit rods 15 vertically arranged on the end surface of the fixing part 1, and a limit groove for the lifting part 2 to be lifted and lowered is formed between the two limit rods 15;

[0044] The two sides of the lifting part 2 are against the corresponding limiting rods 15, so that the lifting part 2 can only perform lifting movement.

[0045] like Figure 1 As shown, in order to ensure the stability of the clamping part during clamping, the utility model adopts the end surface of the lifting part 2 to open two guide grooves 4 arranged vertically; two pairs of connecting rods 6 are arranged vertically, and the sliders 7 at the ends of each pair of connecting rods 6 are located in the same guide groove 4;

[0046] There are two guide grooves 4, and each extension rod 8 has a connecting rod 6 arranged up and down. The slider 7 at the end of the connecting rod 6 is placed in the guide groove 4, and the number of sliders 7 = the number of guide grooves 4 * 2; in this way, during the lifting and lowering process of the lifting plate 2, the approach or distance of the connecting rod 6 is more stable, ensuring the stability of the clamping part 9 during clamping.

[0047] like Figure 4-5 As shown, in order to increase the stability of the clamping part during clamping, the utility model adopts negative pressure holes 16 on both sides of the clamping part 9; one end of the negative pressure hole 16 on one side is connected to the side of the clamping part 9 and the rubber sleeve 10, and the other end is connected to the inner side of the clamping part 9 and the rubber sleeve 10; one end of the negative pressure hole 16 on the other side is connected to the side of the clamping part 9 and the rubber sleeve 10, and the other end is connected to the outer side of the clamping part 9 and the rubber sleeve 10;

[0048] In this solution, a negative pressure space is formed between the contact surface of the rubber sleeve 10 and the material by connecting the negative pressure device to the negative pressure hole 16, thereby improving the stability during clamping; a negative pressure hole 16 is also provided on the outer side of the clamping part 9, and the negative pressure function can also be realized when the clamping part 9 is flipped and fixed.
