Description

Technical Field

[0001] This utility model relates to a mechanical clamp, specifically a clamp-type pipe clamp. Background Technology

[0002] Mechanical fixtures are devices used in the mechanical manufacturing process to install and fix parts or workpieces, keep them in the correct position, and ensure that the position of the parts does not change during the machining process.

[0003] Mechanical fixtures are widely used in various manufacturing industries, especially in the machinery manufacturing industry, where they are essential for fixing workpieces in processes such as drilling, milling, and turning. Furthermore, on automotive production lines, many parts need to be connected through welding or assembly, requiring specialized fixtures to ensure positional accuracy and improve production efficiency.

[0004] In particular, fixing and positioning components is a crucial step in pipeline installation. However, existing clamping structures are often single-function, unable to adapt to the needs of various environments, and the adjustment and replacement of workpieces are time-consuming, impacting production efficiency. Therefore, achieving rapid installation and locking of clamps has become a major challenge. Utility Model Content

[0005] The purpose of this utility model is to provide a clamp-type pipe clamp to solve at least one of the above-mentioned problems, thereby addressing the issue of low production efficiency caused by the difficulty in quickly installing and locking clamps in the prior art. The clamp of this solution can be installed quickly and can be accurately positioned and clamped, thereby improving production efficiency and quality.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A clamp-type pipe clamp includes a base, a clamping mechanism, and a driving mechanism;

[0008] The base has an inverted Y-shaped structure. The input part at the top of the base is connected to the drive mechanism, and the output part at the bottom of the base is connected to the clamping mechanism. The input part and the output part are hinged together.

[0009] The drive mechanism includes a threaded handle and a threaded cylinder, wherein the threaded handle is threadedly connected to the threaded cylinder; the input part of the base is sleeved on the bottom of the threaded handle, and the input part of the base is also slidably connected to the threaded cylinder.

[0010] The clamping mechanism includes a pair of clamps, which are respectively connected to the output part of the base.

[0011] Preferably, the threaded handle includes a handle and a threaded rod; the handle is assembled on the top of the threaded rod to form a T-shaped structure, the threaded rod extends into the threaded cylinder and is screwed to the threaded cylinder, and the bottom of the threaded rod is sleeved with a base.

[0012] Preferably, the threaded cylinder includes a threaded ferrule and a sleeve; the threaded ferrule is the upper end face of the sleeve, and the threaded ferrule is screwed to the threaded handle; the sleeve is slidably connected to the base.

[0013] Preferably, the bottom of the threaded handle is provided with an annular groove, and the input part of the base is provided with a retaining ring, which is in clearance fit with the annular groove.

[0014] Preferably, the bottom of the threaded handle is provided with a retaining ring, and the input part of the base is provided with an annular groove, wherein the retaining ring and the annular groove are in clearance fit.

[0015] Preferably, the clamp is connected to the output part of the base by a first threaded fixing pin and a nut.

[0016] Preferably, the clamp has a C-shaped structure.

[0017] Preferably, the fixture further includes a positioning mechanism, which includes a connecting rod bracket and a side positioning rod;

[0018] The side positioning rods are provided in pairs, with one end of each side positioning rod connected to a pair of clamps and the other end of each side positioning rod connected to both ends of the connecting rod bracket.

[0019] Preferably, the positioning mechanism is an axisymmetric structure.

[0020] Preferably, the side positioning rod is connected to the connecting rod bracket by a second threaded fixing pin and a nut; the side positioning rod is connected to the clamp by a third threaded fixing pin and a nut.

[0021] The working principle of this utility model is as follows:

[0022] In use, rotating the threaded handle can drive the base to rise or fall axially along the threaded cylinder. The output part of the base is tightened or adjusted under the structural constraints of the threaded cylinder, thereby opening and closing the clamps connected to the end of the output part.

[0023] When clamped, rotate the threaded handle to raise it to the top. The bottom side wall of the threaded cylinder blocks the side of the output part of the base, making the included angle smaller (tightening inward), which in turn causes the clamps to close and complete the clamping of the workpiece.

[0024] When relaxation is needed, rotate the threaded handle in the opposite direction to lower it. The base will then lower, and the obstruction between the bottom side wall of the threaded cylinder and the side of the output section will disappear. The output section can then rotate, and the clamps can open, thus completing the relaxation of the workpiece.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The handle and threaded rod in the drive mechanism adopt a T-shaped structure design, which makes it convenient for operators to use and rotate; the threaded engagement allows for more precise control of rotation adjustment, and facilitates quick positioning, clamping and disassembly of workpieces.

[0027] The clamping mechanism adopts a modular design, and its connection with the base is essentially detachable. Therefore, the clamps can be replaced according to the actual working conditions to obtain a more suitable clamping effect.

[0028] The fixture of the present invention can quickly adjust the clamping position and positioning, adapt to workpieces of different shapes and sizes, and improve processing efficiency and accuracy. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] A type of clamp-type pipe clamp, such as Figure 1 As shown, it includes a base 4, a clamping mechanism, and a drive mechanism;

[0034] The base 4 has an inverted Y-shaped structure. The input part at the top of the base 4 is connected to the drive mechanism, and the output part at the bottom of the base 4 is connected to the clamping mechanism. The input part and the output part are hinged together.

[0035] The drive mechanism includes a threaded handle 1 and a threaded cylinder 3, wherein the threaded handle 1 is threadedly connected to the threaded cylinder 3; the input part of the base 4 is sleeved on the bottom of the threaded handle 1, and the input part of the base 4 is also slidably connected to the threaded cylinder 3.

[0036] The clamping mechanism includes a pair of clamps 9, which are respectively connected to the output part of the base 4.

[0037] More specifically, in this embodiment:

[0038] The clamp-type pipe clamp includes a base 4, a clamping mechanism, a drive mechanism, and a positioning mechanism.

[0039] The drive mechanism includes a threaded handle 1 and a threaded cylinder 3, which are threadedly engaged. The threaded handle 1, as shown... Figure 1 As shown, the device includes a handle and a threaded rod forming a T-shaped structure. The handle can be directly welded to the upper end of the threaded rod, so rotating the handle will cause the threaded rod to rotate. The lower part of the threaded rod and the threaded cylinder 3 are connected by a threaded engagement. Furthermore, the lower part of the threaded rod is also connected to the base 4, so that the threaded rod moves up and down while simultaneously causing the base 4 to move up and down. The threaded cylinder 3 consists of a sleeve and a threaded retainer 2, which forms the upper end face of the sleeve. The threaded rod and the threaded retainer 2 are connected by a threaded engagement.

[0040] The base 4 has an inverted Y-shaped structure, including an upper input section and a lower output section. Specifically, it includes an upper first connecting section for connecting to the drive mechanism, and lower second and third connecting sections forming a pair of V-shaped forks. The first, second, and third connecting sections together form a Y-shaped structure and are hinged at their intersections. A retaining ring is provided at the upper end of the first connecting section, which is in clearance fit with an annular groove at the bottom of the threaded rod. Simultaneously, a slider is provided on the side of the first connecting section, which slides in cooperation with an axial groove on the inner wall of the threaded cylinder 3. Therefore, when the threaded rod is rotated, the base 4 does not rotate with the threaded rod, but only moves axially up and down with it. In other embodiments, an annular groove can be provided at the upper end of the first connecting section, and a retaining ring can be connected to the bottom of the threaded rod, with a clearance fit between the two. A pair or multiple pairs of sliders and grooves can be provided; when multiple pairs are provided, they can be arranged at equal intervals along the circumference. There is an angle between the second and third connecting sections and the threaded cylinder 3. Therefore, when the base 4 moves upward with the threaded handle 1, the second and third connecting sections contact the bottom surface of the threaded cylinder 3 and tighten inward, thereby driving the clamps 9 on both sides to close and clamp. When the base 4 moves downward with the threaded handle 1, the second and third connecting sections disengage from the bottom surface of the threaded cylinder 3, and thus can open to drive the clamps 9 to open.

[0041] The clamping mechanism consists of a pair of C-shaped clamps 9, with the ends of the clamps 9 mounted on the base 4. Specifically, the upper ends of both clamps 9 are connected to the lower ends of the second and third connecting sections via a first threaded fixing pin 5 and a hexagonal nut 6. The lower ends of the two clamps 9 face each other, abutting each other when clamping and moving away when releasing. The clamps 9 and the base 4 are actually detachable, allowing for the selection of appropriate clamps 9 based on the workpiece to be clamped during actual use.

[0042] The positioning mechanism includes a connecting rod bracket 7 and side positioning rods 8. A pair of side positioning rods 8 are provided, each connected to an end of the connecting rod bracket 7 and a corresponding clamp 9. More specifically, both ends of the connecting rod bracket 7 are connected to the two side positioning rods 8 via second threaded fixing pins 10 and hexagonal nuts 6, respectively. Furthermore, the two side positioning rods 8 are connected to the two clamps 9 via third threaded fixing pins 11 and hexagonal nuts 6, respectively. Furthermore, the connecting rod bracket 7 can abut or connect to the lower end face of the intersection of the base 4, thereby: the downward movement of the base 4 can synchronously push the connecting rod bracket 7 downward and push the side positioning rods 8 on both sides to open, so as to further cause the clamps 9 to open; if the connecting rod bracket 7 and the base 4 are abutted but not connected, when the base 4 moves upward, the clamps 9 are driven by the tightening of the second connecting section and the third connecting section, and the positioning mechanism is further tightened; if the connecting rod bracket 7 and the base 4 are connected, when the base 4 moves upward, the connecting rod bracket 7 moves upward synchronously and first drives the side positioning rods 8 to retract inward, and at the same time drives the clamps 9 on both sides to retract inward and causes the second connecting section and the third connecting section to retract inward.

[0043] In the above-mentioned mating structure of each threaded fixing bolt and the corresponding nut 6, a threaded locking structure can be further provided (the existing structure can be used, and this solution does not make any improvements to it) to ensure reliable and effective locking when clamping the workpiece.

[0044] When in use, the clamp works as follows: turning the threaded handle 1 drives the base 4 to move up and down, thereby opening and closing the clamps 9 via the threaded cylinder 3 and the positioning mechanism. Therefore, when clamping is required, rotating the threaded handle 1 drives the base 4 upward, and with the threaded cylinder 3 blocking the second and third connecting sections and the linkage of the positioning mechanism, the clamps 9 on both sides can tighten inward to clamp the workpiece. When releasing is required, rotating the threaded handle 1 counterclockwise drives the base 4 downward, and the second and third connecting sections move away from the restriction of the threaded cylinder 3. Simultaneously, with the linkage of the positioning mechanism, the clamps 9 on both sides extend outward to clamp the workpiece.

[0045] This fixture, driven by a threaded connection, allows for a predictable travel distance based on the thread pitch and number of rotations, enabling rapid and precise positioning and clamping. Furthermore, the clamp 9 and base 4 are essentially detachable, allowing for selection of the appropriate clamp 9 based on the workpiece size, thus demonstrating excellent applicability. In addition, its ingenious structural design enables rapid, precise, and stable clamping and transfer operations with fewer structural components. The threaded handle 1 further facilitates the operator's actual rotational operation, indicating promising application prospects.

[0046] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
