Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device. Background Technology

[0002] In many fields such as industrial production, machining, and material handling and fixing, clamping devices are key equipment for achieving stable positioning of items, and their performance directly affects production efficiency, operational safety, and processing accuracy. Currently, the mainstream clamping devices on the market are mainly divided into manual clamping, pneumatic clamping, and hydraulic clamping. Among them, manual clamping devices are still widely used in small and medium-sized production scenarios, temporary fixed operations, and portable operation needs due to their relatively simple structure, low cost, and lack of need for an additional power source.

[0003] Existing manual clamping devices generally rely on linear transmission structures such as bolts and lead screws to achieve clamping action. During operation, it is necessary to continuously rotate the bolt or handle to push the clamping component to move until the item is clamped. This process is not only cumbersome, but also requires operators to repeatedly perform high-intensity rotation operations in operation scenarios that require frequent clamping and disassembly, which can easily lead to increased labor intensity and may cause hand fatigue and affect work efficiency in the long run. On the other hand, after the clamping operation is completed, the operator needs to manually rotate the bolt in the opposite direction or push the clamping component to reset it, which is not convenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device, comprising:

[0006] Base plate;

[0007] A clamping device, which is slidably disposed at both ends of the base plate;

[0008] An adjustment device is detachably mounted on the end of the base plate, and the adjustment device is used to push and compress the clamping device.

[0009] A partition plate, which is detachably installed in the middle of the base plate.

[0010] Preferably, the clamping device includes:

[0011] A skateboard, wherein the skateboard is slidably mounted on the end of a base plate, and the skateboard is C-shaped.

[0012] A clamping plate, which is fixedly installed at the end of the slide plate;

[0013] A limiting component is connected between the slide plate and the base plate.

[0014] Preferably, the limiting component includes:

[0015] The bolt rod has a groove on the sliding plate, and the bolt rod is slidably inserted into the inner cavity of the groove. One end of the bolt rod is fixedly connected to a slider. The base plate has a stepped groove, and the slider and the inner cavity of the stepped groove cooperate with each other.

[0016] The first nut is threaded into the bolt rod.

[0017] Preferably, the adjusting device includes:

[0018] An elastic reset mechanism is mounted on the base plate and is used to reset the clamping device.

[0019] A rotary propulsion mechanism is inserted and installed on an elastic reset mechanism. The rotary propulsion mechanism is used to eccentrically press the clamping device.

[0020] Preferably, the elastic reset mechanism includes:

[0021] The fixing frame is fixedly installed on the base plate;

[0022] A guide rod, one end of which is fixedly connected to the clamping device, and the guide rod is slidably inserted into the fixing frame;

[0023] The first spring is movably sleeved on the outside of the guide rod;

[0024] The second nut is threaded onto the other end of the guide rod.

[0025] Preferably, the rotary propulsion mechanism includes:

[0026] A rotating rod, which is rotatably interlocked with the fixed frame;

[0027] An eccentric wheel is eccentrically inserted and mounted on the rotating rod.

[0028] The handwheel has a rectangular column fixedly connected to one end of the rotating rod, and the handwheel and the rectangular column are slidably interlocked. A limit post is fixedly connected to one end of the rectangular column.

[0029] A card block is fixedly installed on a fixed frame. The card block has a card slot, and the card block is slidably inserted into the inner cavity of the card slot.

[0030] The second spring is movably sleeved on the limiting post.

[0031] The technical effects and advantages of this utility model are as follows:

[0032] This invention utilizes the combined use of a clamping device and an adjusting device. By rotating the rotary propulsion mechanism along its fixed axis, the rotary propulsion mechanism eccentrically presses against the clamping plate. The eccentric wheel pushes the clamping plate toward the object, thus clamping it. This process eliminates the need for operators to continuously rotate bolts or handles, significantly simplifying the operation, reducing labor intensity, avoiding hand fatigue caused by prolonged operation, and improving work efficiency. Furthermore, the rotary propulsion mechanism ensures that the clamping plate returns to a relatively fixed initial position after each reset, effectively preventing positional shifts in the clamping components caused by improper manual reset. This guarantees the stability and reliability of subsequent clamping operations and reduces the occurrence of clamping effects due to positional shifts. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Example 1: As Figures 1-6 A clamping device is shown, comprising: a base plate 100; a clamping device 200 slidably disposed at both ends of the base plate 100; an adjusting device 300 detachably mounted at the end of the base plate 100, the adjusting device 300 being used to press and push the clamping device 200; and a partition plate 400 detachably mounted at the middle of the base plate 100. By rotating a rotary pushing mechanism 302 along a fixed axis, the rotary pushing mechanism 302 causes eccentric pressing of the clamping plate 202, and an eccentric wheel 322 pushes the clamping plate 202 toward the object. The direction of the clamping mechanism ensures that the clamping plate 202 returns to its relatively fixed initial position after each reset. This effectively avoids the problem of clamping component position displacement caused by improper manual reset operation, ensuring the stability and reliability of subsequent clamping operations and reducing the occurrence of clamping effect affected by position displacement.

[0047] Specifically, the clamping device 200 includes: a sliding plate 201, which is slidably disposed at the end of the base plate 100 and is C-shaped; a clamping plate 202, which is fixedly installed at the end of the sliding plate 201; and a limiting component, which is connected between the sliding plate 201 and the base plate 100. The limiting component is slidably disposed at both ends of the base plate 100 in a C-shape by the sliding plate 201, which facilitates limiting the movement of the clamping plate 202. The clamping plate 202 facilitates the squeezing of the item so as to clamp the item. The limiting assembly includes: a bolt rod, a sliding plate 201 with a groove, the bolt rod slidingly interlocking with the inner cavity of the groove, a slider fixedly connected to one end of the bolt rod, a stepped groove on the base plate 100, and the slider engaging with the inner cavity of the stepped groove; a first nut, threadedly engaged with the bolt rod, and through the engagement between the bolt rod and the first nut, and the sliding interlocking between the first bolt rod and the groove, the relative position between the slider and the sliding plate 201 can be adjusted. Through the sliding engagement between the slider and the groove, the relative position between the clamping plate 202 and the base plate 100 can be adjusted to clamp items of different sizes.

[0048] The adjusting device 300 includes: an elastic reset mechanism 301, which is mounted on the base plate 100 and is used to reset the clamping device 200; and a rotary propulsion mechanism 302, which is inserted into the elastic reset mechanism 301 and is used to eccentrically press the clamping device 200.

[0049] The elastic reset mechanism 301 includes: a fixed frame 311, which is fixedly installed on the base plate 100; a guide rod 312, one end of which is fixedly connected to the clamping device 200, and the guide rod 312 is slidably inserted into the fixed frame 311; a first spring 313, which is movably sleeved on the outside of the guide rod 312; and a second nut 314, which is threaded onto the other end of the guide rod 312. Through the sliding insertion between the guide rod 312 and the fixed frame 311, the movement of the clamping plate 202 is further limited, making the linear movement of the clamping plate 202 more stable. The elastic support of the first spring 313 facilitates the reset of the clamping plate 202, so that the clamping plate 202 can be clamped again. The threaded engagement between the second nut 314 and the guide rod 312 prevents the first spring 313 from disengaging, and the second nut 314 also facilitates the adjustment of the elastic force of the first spring 313.

[0050] The rotary propulsion mechanism 302 includes: a rotary rod 321, which is rotatably connected to a fixed frame 311; an eccentric wheel 322, which is eccentrically mounted on the rotary rod 321; a handwheel 323, with a rectangular column fixedly connected to one end of the rotary rod 321, and the handwheel 323 slidably connected to the rectangular column, with a limit post fixedly connected to one end of the rectangular column; a locking block 324, which is fixedly mounted on the fixed frame 311, and has a locking groove, which slidably connects to the inner cavity of the locking groove; and a second spring 325, which is movably sleeved on the limit post. By pulling the handwheel 323 outward, the locking block 324 disengages from the inner cavity of the locking groove. The rotary propulsion mechanism 302 is then activated by the rotational connection between the rotary rod 321 and the fixed frame 311. The eccentric interlocking between the rotating rod 321 and the eccentric wheel 322 causes the eccentric wheel 322 to rotate eccentrically when the rotating rod 321 rotates on its fixed axis. This causes the large diameter of the eccentric wheel 322 to rotate and press towards the clamping plate 202, facilitating the clamping plate 202 to press and slide towards the object. The clamping force of the clamping plate 202 is at its maximum when the maximum diameter of the eccentric wheel 322 is perpendicular to the clamping plate 202. This releases the axial tension applied to the handwheel 323. The elastic support of the handwheel 323 by the second spring 325 causes the handwheel 323 to move towards the locking block 324, allowing the locking block 324 to re-engage with the inner cavity of the locking groove, thereby achieving angular positioning of the handwheel 323 and further facilitating angular positioning of the eccentric wheel 322.

[0051] Example 2: Figure 7 The clamping device shown includes: a base plate 100; and a clamping device 200, which is slidably disposed at both ends of the base plate 100. The clamping device 200 can easily clamp an object.

[0052] Example 3: Figure 8 The clamping device shown includes: a base plate 100; a clamping device 200, which is slidably disposed at both ends of the base plate 100; and a partition plate 400, which is detachably installed in the middle of the base plate 100. Through the partition plate 400, the clamping device 200 can easily clamp two items.

[0053] Example 4: Figure 9 The clamping device shown includes: a base plate 100; a clamping device 200, which is slidably disposed at both ends of the base plate 100; and an adjusting device 300, which is detachably installed at both ends of the base plate 100. The adjusting device 300 is used to squeeze and push the clamping device 200. The arrangement of the two adjusting devices 300 makes the clamping of an item more flexible.

[0054] Example 5: Figure 10 The clamping device shown includes: a base plate 100; a clamping device 200 slidably disposed at both ends of the base plate 100; an adjusting device 300 detachably installed at both ends of the base plate 100, the adjusting device 300 being used to press and push the clamping device 200; and a partition plate 400 detachably installed in the middle of the base plate 100, the partition plate 400 facilitating the clamping of two items.
