Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a sealing clamp and a clamping device. Background Art
[0002] A fixture is a device or tool used to fix, clamp and support a workpiece. Fixtures play an important role in the manufacturing industry, improving work efficiency, ensuring product quality and safety, and simplifying the manufacturing process. Different types of fixtures include manual fixtures, hydraulic fixtures, pneumatic fixtures, mechanical fixtures, etc. They are widely used in various fields such as machining, automobile manufacturing, electronic assembly, aerospace, etc.
[0003] In the prior art, during the electroplating or chemical plating process, the clamp is used to clamp the part to be clamped and immerse it in a liquid so that the part to be clamped reacts with the liquid. During the use of the clamp, the clamping area of the clamp will also contact and react with the liquid, resulting in the formation of a metal layer (such as copper, tin, nickel, etc.) on the surface of the area. After long-term use, these metal layers will accumulate to form metal blocks, thereby affecting the stability of the clamp in clamping the part to be clamped. Utility Model Content
[0004] In view of this, the utility model provides a sealing clamp and a clamping device to solve the problem that the clamping area of the clamp contacts and reacts with the liquid, resulting in the formation of a metal layer on the surface of the area, which affects the stability of the clamp in clamping the clamped object.
[0005] In a first aspect, the utility model provides a sealing fixture, comprising:
[0006] A first clamping arm is provided with a first clamping block arranged at an angle thereto;
[0007] A second clamping arm is rotatably disposed on the first clamping arm, the second clamping arm is provided with a second clamping block which is arranged at an angle thereto, and the second clamping block is arranged corresponding to the first clamping block;
[0008] Two groups of flexible sealing sleeves are respectively sleeved on the first clamping block and the second clamping block, and the end surface of each group of the flexible sealing sleeves protrudes from the clamping surfaces of the first clamping block and the second clamping block correspondingly;
[0009] The sealing clamp has a loose state and a clamping state. In the loose state, the first clamp arm is away from the second clamp arm, and the first clamp block and the second clamp block are away from the part to be clamped. In the clamping state, the first clamp arm and the second clamp arm are arranged opposite to each other, the first clamp block and the second clamp block are respectively clamped on the opposite surfaces of the part to be clamped, and the end surface of each group of the flexible sealing sleeves is sealed with the outer surface corresponding to the part to be clamped.
[0010] Beneficial effect: When the sealing clamp clamps the object to be clamped from the loose state to the clamped state, the second clamp arm rotates toward the first clamp arm. Since the end surface of each group of flexible sealing sleeves protrudes from the clamping surface of the first clamp block and the second clamp block correspondingly, the end surfaces of the two groups of flexible sealing sleeves will first contact the opposite surfaces of the object to be clamped, respectively, and at this time, the first clamp block and the second clamp block have not yet contacted the object to be clamped. As the second clamp arm continues to rotate toward the first clamp arm, the two groups of flexible sealing sleeves are squeezed and deformed, so that the end surfaces of the two groups of flexible sealing sleeves are sealed with the outer surface of the object to be clamped, and at the same time, the first clamp block and the second clamp block clamp the opposite surfaces of the object to be clamped, respectively, and are sealed by the two groups of flexible sealing sleeves and the object to be clamped. In this case, the sealing clamp can safely immerse the object to be clamped in the liquid, thereby preventing the first clamp block and the second clamp block from contacting with the liquid and causing adverse reactions, preventing the formation of metal layers or metal blocks on the clamping surfaces of the first clamp block and the second clamp block, and ensuring that the sealing clamp stably clamps the object to be clamped.
[0011] In the process from the clamping state to the loosening state, the second clamp arm rotates in the direction away from the first clamp arm. First, the first clamp block and the second clamp block respectively loosen the opposite surfaces of the clamped part, and then the end surfaces of the two sets of flexible sealing sleeves gradually separate from the opposite surfaces of the clamped part until the sealing clamp completely loosens the clamped part.
[0012] In the clamping state, the sealing clamp seals the first clamp block and the second clamp block respectively through two sets of flexible sealing sleeves, thereby ensuring that the first clamp block and the second clamp block are firmly clamped and isolated from the liquid. This design effectively prevents the formation of metal layers or metal blocks on the clamping surfaces of the first clamp block and the second clamp block, ensuring that the sealing clamp can still maintain good clamping stability after long-term use.
[0013] In an optional embodiment, a connecting portion is provided at one end of the second clamping arm away from the second clamping block, the connecting portion is arranged at an angle with the second clamping arm, and the second clamping arm is rotatably connected to the first clamping arm via the connecting portion.
[0014] Beneficial effect: A connecting portion is provided at one end of the second clamp arm away from the second clamp block, so that the second clamp arm can be rotatably connected to the first clamp arm through the connecting portion. The connecting portion and the second clamp arm are arranged at an angle, so that the opening angle between the first clamp arm and the second clamp arm can be increased, and the clamping range of the clamp can be expanded, so that it can adapt to workpieces of larger size or irregular shape.
[0015] In an optional embodiment, the end faces of each group of the flexible sealing sleeves are set to be planes.
[0016] Beneficial effect: The end surface of each set of flexible sealing sleeves is set to be a plane, so as to ensure that when the end surface of the flexible sealing sleeve contacts the outer surface of the clamped part, the end surface can completely fit the outer surface of the clamped part. After being squeezed, the end surface of the flexible sealing sleeve can form a tight sealing contact with the outer surface of the clamped part, thereby ensuring that the sealing effect reaches the best state.
[0017] In an optional embodiment, each group of the flexible sealing sleeves is detachably disposed on the first clamping block and the second clamping block.
[0018] Beneficial effect: Since the flexible sealing sleeve is squeezed and deformed for a long time and contacts with liquid, deformation or corrosion may occur, thereby affecting the sealing performance of the flexible sealing sleeve. The flexible sealing sleeve is detachably arranged on the first clamping block and the second clamping block to facilitate replacement of the flexible sealing sleeve, thereby ensuring that the sealing performance is not affected and extending the service life of the clamp.
[0019] In an optional embodiment, a plurality of clamping grooves are provided on the clamping surfaces of the first clamping block and the second clamping block.
[0020] Beneficial effect: By providing clamping grooves on the clamping surfaces of the first clamping block and the second clamping block, the friction between the clamping surfaces and the part to be clamped is increased, thereby improving the clamping stability of the clamp.
[0021] In an optional implementation, it also includes:
[0022] A handle, one end of which is rotatably connected to the second clamping arm;
[0023] A slider, movably disposed on the first clamping arm and adapted to move along the length direction of the first clamping arm;
[0024] an elastic member, which is disposed on the first clamping arm and has one end abutting against the end of the first clamping arm away from the first clamping block, and the other end abutting against the sliding block;
[0025] A connecting member, one end of which is rotatably connected to the slider, and the other end of which is rotatably connected to the handle;
[0026] In the released state, the slider is close to the first clamping block and the other end of the connecting member is away from the slider, and the elastic member is in an initial state; in the clamping state, the slider is away from the first clamping block and the other end of the connecting member is close to the slider, the elastic member is in a compressed state and applies an elastic force to the slider in the direction of the first clamping block to lock the handle.
[0027] Beneficial effect: from the loose state to the clamping state, a force is applied to the handle in the direction of the first clamping arm, so that the handle rotates in the direction of the first clamping arm, driving the second clamping arm to rotate in the direction of the first clamping arm. During the rotation of the handle, the force is transmitted to the slider through the connecting member, so that the slider moves along the length direction of the first clamping arm toward and away from the first clamping block. During the movement of the slider, the slider needs to overcome the elastic force of the elastic member until the sealing clamp enters the clamping state. At this time, the other end of the connecting member is close to the slider, and the elastic member jointly applies an elastic force in the direction of the first clamping block to the slider and the connecting member, so that the connecting member applies a force on the handle to lock the handle, thereby ensuring the stability of the sealing clamp in the clamping state.
[0028] From the clamping state to the loosened state, a force is applied to the handle in a direction away from the first clamp arm, so that the handle rotates in a direction away from the first clamp arm, driving the second clamp arm to rotate in a direction away from the first clamp arm, and the elastic member applies an elastic force in a direction toward the first clamp block to the slider, pushing the slider to move in the direction of the first clamp block, and the other end of the connecting member is away from the slider, and the connecting member will further push the handle to rotate, so that the sealing clamp enters the loosened state.
[0029] In an optional embodiment, an adjusting member for adjusting the tightness of the elastic member is provided at one end of the elastic member.
[0030] Beneficial effect: By adjusting the adjusting piece, the tightness of the elastic piece can be flexibly controlled, thereby flexibly adjusting the locking degree of the elastic piece on the handle when the sealing clamp is in the clamping state.
[0031] In an optional embodiment, a slide groove is provided on the first clamping arm along its length direction, and a guide member connected to the sliding block is movably provided on the slide groove.
[0032] Beneficial effect: By providing the slide groove and the guide piece, the slider can move along a predetermined track during the operation of the fixture, thereby increasing the stability and precision of the fixture.
[0033] In an optional embodiment, a limiting member is further included, and the limiting member is arranged on the first clamping arm close to the first clamping block, and the height of the limiting member is higher than the height of the first clamping block.
[0034] Beneficial effect: A limiter is provided on the first clamp arm near the first clamp block. In the process of clamping the part to be clamped, since the height of the limiter is higher than the height of the first clamp block, when the part to be clamped extends between the first clamp arm and the second clamp arm, the portion of the limiter that is higher than the first clamp block limits the extension length of the part to be clamped, so as to ensure that the first clamp block and the second clamp block can accurately clamp the position of the part to be clamped.
[0035] In a second aspect, the utility model further provides a clamping device, comprising:
[0036] frame;
[0037] A sealing clamp, wherein a plurality of the sealing clamps are provided, and the plurality of sealing clamps are arranged on the frame at intervals.
[0038] Beneficial effect: The first clamping block and the second clamping block are sealed respectively by two sets of flexible sealing sleeves, thereby ensuring that the first clamping block and the second clamping block are firmly clamped and isolated from the liquid, effectively preventing the formation of a metal layer or metal block on the clamping surface of the first clamping block and the second clamping block, and clamping the clamped part by multiple sealing clamps to ensure the clamping stability of the clamping device.

DETAILED DESCRIPTION
[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0046] In the related art, during the electroplating or chemical plating process, the clamp is used to clamp the part to be clamped and immerse it in the liquid so that the part to be clamped reacts with the liquid. During the use of the clamp, the clamping area of the clamp will also contact and react with the liquid, resulting in the formation of a metal layer (such as copper, tin, nickel, etc.) on the surface of the area. After long-term use, these metal layers will accumulate to form metal blocks, thereby affecting the stability of the clamp in clamping the part to be clamped.
[0047] In order to solve the above technical problems, the following Figures 1 to 3 , describing an embodiment of the utility model.
[0048] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 3 As shown, a sealing clamp is provided, comprising a first clamp arm 1 , a second clamp arm 3 and two sets of flexible sealing sleeves 5 .
[0049] Specifically, Figure 1 As shown, a first clamping block 2 is disposed on the first clamping arm 1 , and the first clamping block 2 is arranged at an angle to the first clamping arm 1 .
[0050] Specifically, Figure 1 As shown, the second clamp arm 3 is rotatably disposed on the first clamp arm 1 , and a second clamp block 4 is disposed on the second clamp arm 3 . The second clamp block 4 is disposed at an angle to the second clamp arm 3 , and the second clamp block 4 is disposed corresponding to the first clamp block 2 .
[0051] Specifically, Figure 1 As shown, two groups of flexible sealing sleeves 5 are respectively sleeved on the first clamping block 2 and the second clamping block 4, and the end surface of each group of flexible sealing sleeves 5 protrudes from the clamping surfaces of the first clamping block 2 and the second clamping block 4 correspondingly.
[0052] The sealing fixture has a loose state and a clamped state. In the loose state (such as Figure 1 As shown in FIG. 1 , the first clamp arm 1 is away from the second clamp arm 3, and the first clamp block 2 and the second clamp block 4 are away from the clamped object. Figure 2 As shown), the first clamp arm 1 and the second clamp arm 3 are arranged opposite to each other, the first clamp block 2 and the second clamp block 4 are clamped on the opposite surfaces of the clamped part respectively, and the end surface of each group of flexible sealing sleeves 5 is sealed with the corresponding outer surface of the clamped part.
[0053] When the sealing clamp clamps the object to be clamped from the loose state to the clamped state, the second clamp arm 3 rotates toward the first clamp arm 1. Since the end surface of each group of flexible sealing sleeves 5 protrudes from the clamping surface of the first clamp block 2 and the second clamp block 4 correspondingly, the end surfaces of the two groups of flexible sealing sleeves 5 will first contact the opposite surfaces of the object to be clamped, respectively, and at this time, the first clamp block 2 and the second clamp block 4 have not yet contacted the object to be clamped. As the second clamp arm 3 continues to rotate toward the first clamp arm 1, the two groups of flexible sealing sleeves 5 are squeezed and deformed, so that the end surfaces of the two groups of flexible sealing sleeves 5 are sealed with the outer surface of the object to be clamped, and at the same time, the first clamp block 2 and the second clamp block 4 clamp the opposite surfaces of the object to be clamped, respectively, and are sealed by the two groups of flexible sealing sleeves 5 and the object to be clamped. In this case, the sealing clamp can safely immerse the object to be clamped in the liquid, thereby preventing the first clamp block 2 and the second clamp block 4 from contacting with the liquid and causing adverse reactions, preventing the formation of metal layers or metal blocks on the clamping surfaces of the first clamp block 2 and the second clamp block 4, and ensuring that the sealing clamp stably clamps the object to be clamped.
[0054] In the process from the clamping state to the releasing state, the second clamp arm 3 rotates in the direction away from the first clamp arm 1. First, the first clamp block 2 and the second clamp block 4 release the opposite surfaces of the clamped part respectively, and then the end surfaces of the two sets of flexible sealing sleeves 5 gradually separate from the opposite surfaces of the clamped part until the sealing clamp completely releases the clamped part.
[0055] In the clamping state, the sealing clamp seals the first clamp block 2 and the second clamp block 4 respectively through two sets of flexible sealing sleeves 5, thereby ensuring that the first clamp block 2 and the second clamp block 4 are firmly clamped and isolated from the liquid. This design effectively prevents the formation of a metal layer or metal block on the clamping surface of the first clamp block 2 and the second clamp block 4, ensuring that the sealing clamp can still maintain good clamping stability after long-term use.
[0056] Specifically, a through hole 501 is formed in the flexible sealing sleeve 5 , so that the flexible sealing sleeve 5 can be sleeved on the first clamping block 2 or the second clamping block 4 .
[0057] Specifically, the embodiment of the present application does not impose any specific restrictions on the rotation form of the first clamp arm 1 and the second clamp arm 3, and any existing rotation structure can be selected as needed. In addition, the specific shapes of the first clamp arm 1 and the second clamp arm 3 are not limited.
[0058] Specifically, the first clamp arm 1 and the first clamp block 2 can be set at any angle. In the embodiment of the present application, there is no restriction on the angle between the first clamp arm 1 and the first clamp block 2. Similarly, there is no restriction on the angle between the second clamp arm 3 and the second clamp block 4.
[0059] Specifically, the flexible sealing sleeve 5 can be selected from existing sealing sleeves such as a rubber sleeve, a polyurethane sleeve, etc. In the embodiment of the present application, no specific limitation is imposed on the material of the flexible sealing sleeve 5.
[0060] Specifically, in the embodiment of the present application, there is no specific restriction on the height of the end surface of the flexible sealing sleeve 5 protruding from the clamping surface of the first clamping block 2 or the second clamping block 4. For example, the flexible sealing sleeve 5 is 0.5 cm higher than the clamping surface of the first clamping block 2.
[0061] In one embodiment, in combination Figure 1 and Figure 3 As shown, a connecting portion 301 is provided at one end of the second clamping arm 3 away from the second clamping block 4 . The connecting portion 301 and the second clamping arm 3 are arranged at an angle. The second clamping arm 3 is rotatably connected to the first clamping arm 1 via the connecting portion 301 .
[0062] A connecting portion 301 is provided at one end of the second clamping arm 3 away from the second clamping block 4, so that the second clamping arm 3 is rotatably connected to the first clamping arm 1 through the connecting portion 301. The connecting portion 301 is arranged at an angle with the second clamping arm 3, so that the opening angle between the first clamping arm 1 and the second clamping arm 3 can be increased, and the clamping range of the clamp can be expanded, so that it can adapt to workpieces of larger size or irregular shape.
[0063] In one embodiment, if Figure 3 As shown, the end surface of each set of flexible sealing sleeves 5 is set to be a plane to ensure that when the end surface of the flexible sealing sleeve 5 contacts the outer surface of the clamped part, the end surface can completely fit the outer surface of the clamped part. After being squeezed, the end surface of the flexible sealing sleeve 5 can form a tight sealing contact with the outer surface of the clamped part, thereby ensuring that the sealing effect reaches the best state.
[0064] Specifically, the flexible sealing sleeve 5 can be set in a regular shape such as a cylinder, a cuboid, a cube, etc., or can be set in other irregular shapes. In the embodiment of the present application, the shape of the flexible sealing sleeve 5 is not specifically limited.
[0065] In one embodiment, each set of flexible sealing sleeves 5 is detachably disposed on the first clamping block 2 and the second clamping block 4 .
[0066] Since the flexible sealing sleeve 5 is squeezed and deformed for a long time and contacts with liquid, deformation or corrosion may occur, thereby affecting the sealing performance of the flexible sealing sleeve 5. The flexible sealing sleeve 5 is detachably arranged on the first clamping block 2 and the second clamping block 4 to facilitate replacement of the flexible sealing sleeve 5, thereby ensuring that the sealing performance is not affected and extending the service life of the clamp.
[0067] Specifically, in the embodiment of the present application, there is no specific restriction on the detachable manner of the flexible sealing sleeve 5. The flexible sealing sleeve 5 can be detachably arranged by an elastic sleeve installation method, or by a fastener connection.
[0068] In one embodiment, if Figure 3As shown, a plurality of clamping grooves 201 are formed on the clamping surfaces of the first clamping block 2 and the second clamping block 4 .
[0069] By providing clamping grooves 201 on the clamping surfaces of the first clamping block 2 and the second clamping block 4, the friction between the clamping surfaces and the part to be clamped is increased, thereby improving the clamping stability of the clamp.
[0070] Specifically, the clamping groove 201 can be set to be a V-shaped groove, an annular groove, etc., or the clamping surface can also be set to be other shapes such as a serrated shape to increase the friction between the clamping surface and the part to be clamped. In the embodiment of the present application, no specific restrictions are imposed on the shapes of the clamping groove 201 and the clamping surface.
[0071] In one embodiment, if Figure 1 As shown, it also includes a handle 6, a slider 7, an elastic member 8 and a connecting member 9.
[0072] Specifically, Figure 1 As shown, one end of the handle 6 is rotatably connected to the second clamp arm 3 , and the second clamp arm 3 is driven to rotate by applying an external force to the handle 6 .
[0073] Specifically, Figure 1 As shown, the slider 7 is movably disposed on the first clamping arm 1 , and the slider 7 is suitable for moving along the length direction of the first clamping arm 1 .
[0074] Specifically, Figure 1 As shown, the elastic member 8 is disposed on the first clamping arm 1 , one end of the elastic member 8 abuts against the end of the first clamping arm 1 away from the first clamping block 2 , and the other end of the elastic member 8 abuts against the slider 7 .
[0075] Specifically, Figure 1 As shown, one end of the connecting member 9 is rotatably connected to the slider 7 , and the other end is rotatably connected to the handle 6 .
[0076] In the loose state (such as Figure 1 As shown in FIG. 1 ), the slider 7 is close to the first clamping block 2 and the other end of the connecting member 9 is away from the slider 7, and the elastic member 8 is in the initial state. Figure 2 As shown), the slider 7 is away from the first clamping block 2, the other end of the connecting member 9 is close to the slider 7, the elastic member 8 is in a compressed state and applies an elastic force to the slider 7 toward the first clamping block 2 to lock the handle 6.
[0077] From the released state to the clamped state, a force is applied to the handle 6 in the direction of the first clamp arm 1, so that the handle 6 rotates in the direction of the first clamp arm 1, driving the second clamp arm 3 to rotate in the direction of the first clamp arm 1. During the rotation of the handle 6, the force is transmitted to the slider 7 through the connecting member 9, so that the slider 7 moves along the length direction of the first clamp arm 1 toward and away from the first clamp block 2. During the movement of the slider 7, the slider 7 needs to overcome the elastic force of the elastic member 8 until the sealing clamp enters the clamped state. At this time, the other end of the connecting member 9 is close to the slider 7, and the elastic member 8 jointly applies an elastic force to the slider 7 and the connecting member 9 in the direction of the first clamp block 2, so that the connecting member 9 applies a force on the handle 6 to lock the handle 6, thereby ensuring the stability of the sealing clamp in the clamped state.
[0078] From the clamping state to the loosened state, a force is applied to the handle 6 in the direction away from the first clamp arm 1, so that the handle 6 rotates in the direction away from the first clamp arm 1, driving the second clamp arm 3 to rotate in the direction away from the first clamp arm 1, and the elastic member 8 applies an elastic force in the direction of the first clamp block 2 to the slider 7, pushing the slider 7 to move in the direction of the first clamp block 2, and the other end of the connecting member 9 is away from the slider 7, and the connecting member 9 will further push the handle 6 to rotate, so that the sealing clamp enters the loosened state.
[0079] Specifically, the elastic member 8 can be selected from existing elastic members such as coil springs or compression springs. In the embodiment of the present application, no specific limitation is imposed on the type of elastic force.
[0080] Specifically, the connecting member 9 can be provided in a rod shape, a sheet shape, etc. In the embodiment of the present application, the shape of the connecting member 9 is not specifically limited.
[0081] In one embodiment, if Figure 1 As shown, an adjusting member 10 is provided at one end of the elastic member 8 , and the adjusting member 10 is used to adjust the tightness of the elastic member 8 .
[0082] By adjusting the adjusting member 10 , the tightness of the elastic member 8 can be flexibly controlled, thereby flexibly adjusting the locking degree of the elastic member 8 on the handle 6 when the sealing clamp is in the clamping state.
[0083] In one embodiment, if Figure 1 As shown, a slide groove 101 is provided on the first clamping arm 1 along its length direction, and a guide member 11 is movably provided on the slide groove 101 , and the guide member 11 is connected to the slider 7 .
[0084] By providing the slide groove 101 and the guide member 11 , the slide block 7 can move along a predetermined track during the operation of the clamp, thereby increasing the stability and precision of the clamp.
[0085] In one embodiment, if Figure 1As shown, it also includes a limiting member 12 , which is arranged on the first clamping arm 1 close to the first clamping block 2 , and the height of the limiting member 12 is higher than the height of the first clamping block 2 .
[0086] A limiter 12 is provided on the first clamp arm 1 near the first clamp block 2. In the process of clamping the piece to be clamped, since the height of the limiter 12 is higher than the height of the first clamp block 2, when the piece to be clamped extends between the first clamp arm 1 and the second clamp arm 3, the portion of the limiter 12 that is higher than the first clamp block 2 limits the extension length of the piece to be clamped, so as to ensure that the first clamp block 2 and the second clamp block 4 can accurately clamp the position of the piece to be clamped.
[0087] Specifically, a protective cover 13 may be provided on the first clamping arm 1 and the second clamping arm 3 to protect the first clamping arm 1 and the second clamping arm 3 and prevent the first clamping arm 1 and the second clamping arm 3 from coming into contact with liquid and causing a reaction.
[0088] The working principle of the sealing fixture in this embodiment is described as follows:
[0089] 1) From the loose state to the clamping state, clamp the part to be clamped:
[0090] The outside world applies a force to the handle 6 in the direction of the first clamp arm 1, so that the handle 6 rotates in the direction of the first clamp arm 1, driving the second clamp arm 3 to rotate in the direction of the first clamp arm 1. Since the end surface of each group of flexible sealing sleeves 5 protrudes from the clamping surfaces of the first clamp block 2 and the second clamp block 4 correspondingly, the end surfaces of the two groups of flexible sealing sleeves 5 will first contact the opposite surfaces of the clamped part, respectively, at which time the first clamp block 2 and the second clamp block 4 have not yet contacted the clamped part. As the second clamp arm 3 continues to rotate toward the first clamp arm 1, the two groups of flexible sealing sleeves 5 are squeezed and deformed, so that the end surfaces of the two groups of flexible sealing sleeves 5 are sealed with the outer surface of the clamped part. At the same time, the first clamp block 2 and the second clamp block 4 clamp the opposite surfaces of the clamped part, respectively, and are sealed by the two groups of flexible sealing sleeves 5 and the clamped part. In this case, the sealing clamp can safely immerse the part to be clamped in the liquid, thereby preventing the first clamp block 2 and the second clamp block 4 from contacting the liquid and causing adverse reactions, preventing the formation of a metal layer or metal block on the clamping surfaces of the first clamp block 2 and the second clamp block 4, and ensuring that the sealing clamp stably clamps the part to be clamped.
[0091] During the rotation of the handle 6, the force is transmitted to the slider 7 through the connecting member 9, so that the slider 7 moves along the length direction of the first clamping arm 1 toward and away from the first clamping block 2. During the movement of the slider 7, the slider 7 needs to overcome the elastic force of the elastic member 8 until the sealing clamp enters the clamping state. At this time, the other end of the connecting member 9 is close to the slider 7, and the elastic member 8 jointly applies an elastic force toward the first clamping block 2 to the slider 7 and the connecting member 9, so that the connecting member 9 applies a force to the handle 6 for locking the handle 6.
[0092] 2) From the clamping state to the loosening state, release the clamped part:
[0093] The outside world applies a force to the handle 6 in a direction away from the first clamp arm 1, causing the handle 6 to rotate in a direction away from the first clamp arm 1, driving the second clamp arm 3 to rotate in a direction away from the first clamp arm 1, and the first clamp block 2 and the second clamp block 4 respectively release the opposite surfaces of the part to be clamped, and then, the end surfaces of the two sets of flexible sealing sleeves 5 gradually separate from the opposite surfaces of the part to be clamped until the sealing clamp completely releases the part to be clamped.
[0094] During this process, the elastic member 8 applies an elastic force to the slider 7 toward the first clamping block 2, pushing the slider 7 to move toward the first clamping block 2. The other end of the connecting member 9 moves away from the slider 7, and the connecting member 9 further pushes the handle 6 to rotate so that the sealing clamp enters a loosened state.
[0095] According to an embodiment of the present utility model, on the other hand, a clamping device is provided, including a frame and a sealing clamp.
[0096] Specifically, a plurality of sealing clamps are provided, and the plurality of sealing clamps are arranged on the frame at intervals.
[0097] This clamping device seals the first clamping block 2 and the second clamping block 4 respectively through two sets of flexible sealing sleeves 5, thereby ensuring that the first clamping block 2 and the second clamping block 4 are firmly clamped and isolated from the liquid, effectively preventing the formation of a metal layer or metal block on the clamping surface of the first clamping block 2 and the second clamping block 4, and clamping the clamped part through multiple sealing clamps to ensure the clamping stability of the clamping device.
[0098] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
