Description

Technical Field

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

[0002] Existing plastic pipes or power cables need to be processed into predetermined lengths using cutting equipment. Before cutting, the pipes need to be fixed. In factories, clamps are usually used to clamp the pipes to facilitate cutting. However, if the exposed length of the pipe is not suitable after clamping, the clamp needs to be opened to release the pipe, then the pipe needs to be adjusted to the appropriate exposed length, and then clamped again before cutting. This is quite troublesome and urgently needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a pipe clamping device that can pre-position the pipe, facilitate the adjustment of the cutting length, and improve the efficiency of pipe cutting.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pipe clamping device, comprising a support body, wherein the support body is provided with: The pre-clamping structure includes a first drive structure, a first retaining jaw, and a second retaining jaw. The first drive structure drives the first retaining jaw and the second retaining jaw to clamp the pipe and allow the pipe to slide axially. The clamping structure includes a fixed clamping component and a movable clamping component. The bracket body is provided with a second driving structure, which drives the movable clamping component to approach the fixed clamping component and clamp the pipe, or drives the movable clamping component to move away from the fixed clamping component and release the pipe.

[0005] By adopting the above technical solution, the pipe is passed between the first and second retaining jaws of the pre-clamping structure. The first driving structure drives the first and second retaining jaws to clamp and position the pipe. At the same time, it ensures that the pipe can slide axially under the action of external force, thereby adjusting the exposed length of the pipe. When the exposed length of the pipe is not suitable, it can be adjusted by pushing or pulling the pipe. After the adjustment is completed, the second driving structure drives the movable clamping component and the fixed clamping component to clamp and fix the pipe. This prevents the pipe from sliding axially or shaking radially relative to the clamping structure, making it convenient to cut the pipe. It has the effect of pre-positioning the pipe, facilitating the adjustment of the cutting length, and improving the cutting efficiency of the pipe.

[0006] The present invention is further configured such that: the fixed clamping assembly includes a fixed base and a clamping piece 1 detachably mounted on the fixed base; the movable clamping assembly includes a movable base and a clamping piece 2 detachably mounted on the movable base; the clamping surfaces of the clamping piece 1 and the clamping piece 2 are provided with clamping grooves corresponding to the pipe fittings.

[0007] By adopting the above technical solution, clamping plate one and clamping plate two are designed to be detachable, which facilitates the cleaning or replacement of clamping plate one and clamping plate two. At the same time, the opening of the clamping groove can improve the clamping force of clamping plate one and clamping plate two on the pipe fitting.

[0008] A further feature of this invention is that: the fixed seat has a first mounting groove corresponding to the clamping piece one, the movable seat has a second mounting groove corresponding to the clamping piece two, the fixed seat and the movable seat have positioning posts in the corresponding first mounting groove and second mounting groove, the clamping piece one and the clamping piece two have positioning holes corresponding to the positioning posts, and the positioning posts are inserted into the positioning holes for positioning.

[0009] By adopting the above technical solution, the insertion of the positioning pin and the positioning hole makes the clamping plate one and clamping plate two more securely installed on the corresponding fixed seat and movable seat.

[0010] A further feature of this invention is that the fixed seat and the movable seat are provided with stop steps in the corresponding first mounting groove and second mounting groove, respectively. When the clamping piece one and the clamping piece two are installed in the first mounting groove and the second mounting groove, the clamping piece one and the clamping piece two cooperate with the stop steps.

[0011] By adopting the above technical solution, the stop step can prevent the pipe fitting from sliding when the clamping piece 1 and clamping piece 2 are installed into the corresponding first and second mounting slots, thus avoiding the situation where the clamping piece 1 and clamping piece 2 fall off.

[0012] A further feature of this invention is that the fixed seat and the movable seat are provided with threaded holes, and a ball plunger is threadedly connected to the threaded holes. The ball plunger includes an external threaded sleeve, a spring and a retaining ball disposed within the external threaded sleeve. The first clamping piece and the second clamping piece are provided with positioning grooves corresponding to the retaining ball. The spring pushes the retaining ball to press against the positioning groove, so that the first clamping piece and the fixed seat are anti-disengaged, and the second clamping piece and the movable seat are anti-disengaged.

[0013] By adopting the above technical solution, the ball plunger can be detachably installed on the corresponding fixed seat and movable seat. The spring of the ball plunger pushes the retaining ball to press against the positioning groove, so that the clamping plate one and clamping plate two are fastened in the corresponding first mounting groove and second mounting groove, thereby improving the ease of disassembly and assembly and the stability of installation of clamping plate one and clamping plate two.

[0014] A further feature of this invention is that positioning grooves are provided at both the upper and lower ends of the clamping plate one and the clamping plate two, and ball-head plungers are provided at the upper and lower ends of the fixed seat and the movable seat respectively.

[0015] By adopting the above technical solution, the combination of multiple sets of ball-head plungers and positioning grooves can make the installation of clamping plate one and clamping plate two on the corresponding fixed seat and movable seat more secure.

[0016] A further feature of this invention is that the movable seat has an embedded portion, and the fixed seat has a recessed portion corresponding to the embedded portion, with the embedded portion and the recessed portion providing a guiding fit.

[0017] By adopting the above technical solution, the translation direction of the movable seat relative to the fixed seat is more consistent, thereby improving the clamping stability of the clamping structure of this utility model for the pipe fitting.

[0018] A further feature of this invention is that the main body of the support is provided with a slide rail, and the movable seat is provided with a slide groove corresponding to the slide rail, with the slide rail and the slide groove providing a guiding fit.

[0019] By adopting the above technical solution, the translation direction of the movable seat relative to the fixed seat is more consistent, thereby improving the accuracy of operation of this utility model.

[0020] A further feature of this invention is that the first driving structure is a clamping cylinder, the first retaining jaw is connected to the first output end of the clamping cylinder, and the second retaining jaw is connected to the second output end of the clamping cylinder.

[0021] By adopting the above technical solution, the clamping cylinder can achieve bidirectional controllable force output, with stable force output and rapid response, enabling high-precision operation and improving the accuracy of the clamping force control of the pipe fittings in this utility model.

[0022] A further feature of this invention is that the support body is provided with a material dropping plate at an angle below the clamping structure, and a material receiving frame is provided below the material dropping plate.

[0023] By adopting the above technical solution, the blanking plate can slide the debris generated during pipe cutting into the receiving frame for collection.

[0024] In summary, this utility model has the following beneficial effects: The system employs a pre-clamping structure and a clamping structure on the support body. The pre-clamping structure includes a first driving structure, a first retaining jaw, and a second retaining jaw. The clamping structure includes a fixed clamping assembly and a movable clamping assembly. The support body is equipped with a second driving structure. By passing the pipe through the first and second retaining jaws of the pre-clamping structure, the first driving structure drives the first and second retaining jaws to clamp and position the pipe. This ensures that the pipe can slide axially under external force, allowing adjustment of the exposed length of the pipe. When the exposed length is unsuitable, the pipe can be adjusted by pushing or pulling it. After adjustment, the second driving structure drives the movable clamping assembly and the fixed clamping assembly to clamp and fix the pipe, preventing the pipe from sliding axially or wobbling radially relative to the clamping structure. This facilitates pipe cutting and has the advantages of pre-positioning the pipe for easy adjustment of the cutting length and improved pipe cutting efficiency. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] A pipe clamping device, such as Figures 1-4 As shown, the device includes a support body 1, on which a pre-clamping structure 2 and a clamping structure 3 are provided. The pre-clamping structure 2 includes a first driving structure 21, a first retaining claw 22 and a second retaining claw 23. The first driving structure 21 drives the first retaining claw 22 and the second retaining claw 23 to clamp the pipe 6 and allow the pipe 6 to slide axially. The clamping structure 3 includes a fixed clamping assembly 31 and a movable clamping assembly 32. The support body 1 is provided with a second driving structure 33. The second driving structure 33 drives the movable clamping assembly 32 to approach the fixed clamping assembly 31 and clamp the pipe 6, or the second driving structure 33 drives the movable clamping assembly 32 away from the fixed clamping assembly 31 and releases the pipe 6.

[0035] like Figures 3-7As shown, the fixed clamping assembly 31 includes a fixed base 311 and a clamping piece 312 detachably mounted on the fixed base 311. The movable clamping assembly 32 includes a movable base 321 and a clamping piece 322 detachably mounted on the movable base 321. The clamping surfaces of the clamping pieces 312 and 322 are provided with clamping grooves 3a opposite to the pipe 6. The clamping pieces 312 and 322 are designed to be detachable, which facilitates the clamping of the clamping pieces 312 and 322. The cleaning or replacement of clamping plate 322, along with the opening of clamping groove 3a, can improve the clamping force of clamping plate 1 312 and clamping plate 2 322 on pipe fitting 6; the fixed seat 311 has a first mounting groove 3111 corresponding to clamping plate 1 312, and the movable seat 321 has a second mounting groove 3211 corresponding to clamping plate 2 322. The fixed seat 311 and the movable seat 321 have positioning posts 34 in the corresponding first mounting groove 3111 and second mounting groove 3211, respectively, for clamping. Clamping piece 312 and clamping piece 322 have positioning holes 3b on their corresponding positioning posts 34. The positioning posts 34 are inserted into the positioning holes 3b for positioning. This insertion of the positioning posts 34 into the positioning holes 3b makes the clamping pieces 312 and 322 more securely mounted on their corresponding fixed seats 311 and movable seats 321. The fixed seats 311 and movable seats 321 have stop steps 3c in their corresponding first mounting grooves 3111 and second mounting grooves 3211, respectively. When the first clamping piece 312 and the second clamping piece 322 are installed in the first mounting groove 3111 and the second mounting groove 3211, the first clamping piece 312 and the second clamping piece 322 cooperate with the corresponding stop step 3c. The stop step 3c can prevent the pipe fitting 6 from sliding when the first clamping piece 312 and the second clamping piece 322 are installed in the corresponding first mounting groove 3111 and second mounting groove 3211, thus avoiding the situation where the first clamping piece 312 and the second clamping piece 322 fall off.

[0036] like Figures 6-7As shown, the fixed seat 311 and the movable seat 321 are provided with threaded holes 3d. A ball plunger 35 is internally threaded into the threaded holes 3d. The ball plunger 35 includes an external threaded sleeve 351, a spring 352 and a retaining ball 353 disposed in the external threaded sleeve 351. The clamping plate 1 312 and the clamping plate 2 322 are provided with positioning grooves 3e corresponding to the retaining ball 353. The spring 352 pushes the retaining ball 353 to press against the positioning groove 3e, so that the clamping plate 1 312 and the fixed seat 311, and the clamping plate 2 322 and the movable seat 321 are anti-disengaged. This allows the ball plunger 35 to be detachably installed on the corresponding fixed seat 311 and movable seat 321. The spring 352 of the ball plunger 35 pushes the retaining ball 353. The clamping pieces 312 and 322 are secured in the positioning grooves 3e, thus ensuring they are firmly fixed within the corresponding first mounting grooves 3111 and second mounting grooves 3211. This improves the ease of assembly and disassembly of the clamping pieces 312 and 322 and enhances their installation stability. Positioning grooves 3e are provided at both the upper and lower ends of the clamping pieces 312 and 322. Ball-head plungers 35 are correspondingly provided at the upper and lower ends of the first mounting grooves 3111 and second mounting grooves 3211. The combination of multiple sets of ball-head plungers 35 and positioning grooves 3e further strengthens the secure installation of the clamping pieces 312 and 322 on the corresponding fixed and movable seats 311 and 321.

[0037] like Figures 1-7 As shown, the movable seat 321 is provided with an insert portion 3212, and the fixed seat 311 is provided with a recessed portion 3112 corresponding to the insert portion 3212. The insert portion 3212 and the recessed portion 3112 are guided and engaged, making the translational direction of the movable seat 321 relative to the fixed seat 311 more consistent, thereby improving the clamping stability of the clamping structure 3 of this utility model for the pipe fitting 6; the support body 1 is provided with a slide rail 11, and the movable seat 321 is provided with a slide groove 3213 corresponding to the slide rail 11. The slide rail 11 and the slide groove 3213 are guided and engaged, making the translational direction of the movable seat 321 relative to the fixed seat 311 more consistent, thereby improving the operational accuracy of this utility model; the first drive structure 21 is provided as a clamping cylinder, and the first holding gripper 22 is connected to the clamping cylinder. One output end, the second holding gripper 23 is connected to the second output end of the clamping cylinder. The clamping cylinder can achieve bidirectional controllable force output, with stable force output and rapid response, enabling high-precision operation and improving the accuracy of the clamping force control of the pipe fitting 6 in this utility model. The second drive structure 33 in this embodiment is set as a motor lead screw pair structure. The support body 1 is inclinedly provided with a dropping plate 4 below the clamping structure 3, and a receiving frame 5 is provided below the dropping plate 4. The dropping plate 4 can slide the debris generated when the pipe fitting 6 is cut into the receiving frame 5 for collection. In this embodiment, the support body 1 is provided with an upper chip-blocking sheet metal 12 and a lower chip-blocking sheet metal 13. The upper chip-blocking sheet metal 12 and the lower chip-blocking sheet metal 13 cooperate to better guide the debris onto the dropping plate 4.

[0038] The basic working principle of this utility model is as follows: A pre-clamping structure 2 and a clamping structure 3 are provided on the support body 1. The pre-clamping structure 2 includes a first driving structure 21, a first retaining claw 22, and a second retaining claw 23. The clamping structure 3 includes a fixed clamping component 31 and a movable clamping component 32. The support body 1 is provided with a second driving structure 33. By passing the pipe 6 between the first retaining claw 22 and the second retaining claw 23 of the pre-clamping structure 2, the first driving structure 21 drives the first retaining claw 22 and the second retaining claw 23 to move the pipe 6 into the support body 1. The clamping and positioning mechanism ensures that the pipe fitting 6 can slide axially under external force, thereby adjusting the exposed length of the pipe fitting 6. When the exposed length of the pipe fitting 6 is not suitable, it can be adjusted by pushing or pulling the pipe fitting 6. After adjustment, the second drive structure 33 drives the movable clamping assembly 32 and the fixed clamping assembly 31 to clamp and fix the pipe fitting 6, so that the pipe fitting 6 will not slide axially or shake radially relative to the clamping structure 3, which facilitates the cutting of the pipe fitting 6. It has the effect of pre-positioning the pipe fitting, facilitating the adjustment of the cutting length, and improving the cutting efficiency of the pipe fitting.

[0039] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
