Description

Technical Field

[0001] This utility model relates to the field of chamfering machine technology, specifically a material clamping device for a three-way chamfering machine. Background Technology

[0002] During the production of tee fittings, chamfering is often required. A tee chamfering machine is a mechanical device used to chamfer tee fittings. The material clamping device is used to fix and position the tee fitting, ensuring that it does not move during the chamfering process and guaranteeing processing accuracy.

[0003] Existing T-joint chamfering machines have fixed material clamping devices that do not allow for rotation of the T-joint. This means that the T-joint must be disassembled and reassembled multiple times to chamfer the three ends of the T-joint, resulting in low chamfering efficiency.

[0004] Therefore, this utility model provides a material clamping device for a three-way chamfering machine to solve the above problems. Utility Model Content

[0005] This utility model provides a material clamping device for a three-way chamfering machine, which aims to solve the problems mentioned in the background art, such as the existing material clamping devices of the three-way chamfering machine being fixed and lacking the function of rotating the three-way connector, which requires multiple disassembly and reassembly of the connector to complete the chamfering of the three ends of the three-way connector, resulting in low chamfering efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material clamping device for a three-way chamfering machine, comprising a base plate, a first motor mounted on the front side of the base plate, a lead screw provided at the drive end of the first motor, a T-block being threaded onto the lead screw, an adjustment structure being mounted on the end face of the T-block, and a clamp being mounted on the adjustment structure;

[0007] The adjustment structure includes a fixed frame mounted on the end face of the T-block. A second motor is installed on the inner end face of the fixed frame. A rotating plate is mounted on the drive end of the second motor and on the upper side of the fixed frame. A connecting ring is installed at the bottom of the rotating plate. A limit groove is formed on the fixed frame corresponding to the connecting ring. By setting up the adjustment structure, the clamp rotates with the rotating plate, realizing the function of rotating the tee connector. This allows the tee connector to be chamfered at all three ends without multiple disassembly and assembly, avoiding the problem that existing tee chamfering machines have fixed material clamping devices that do not have the function of rotating the tee connector, requiring multiple disassembly and assembly of the connector to chamfer the three ends of the tee connector. This improves the chamfering efficiency of the tee connector.

[0008] Preferably, a first T-shaped support plate is installed on the end face of the rotating plate and on both the front and rear sides, and a second T-shaped support plate is installed on the end face of the rotating plate and on the left side of the first T-shaped support plate.

[0009] Preferably, the clamp includes a support plate mounted on the end face of the rotating plate and a fixing plate disposed on the right side of the end face of the rotating plate. A first arc-shaped plate is mounted on the upper side of the support plate, and a screw is mounted on the support plate through a threaded hole. A second arc-shaped plate is rotatably mounted on the end of the screw near the first arc-shaped plate through a bearing. A sliding plate is mounted on the lower side of the second arc-shaped plate.

[0010] Preferably, the first arc-shaped plate has an opening, the inner walls of the first and second arc-shaped plates are provided with first rubber pads, the end of the screw away from the second arc-shaped plate is provided with a knob, and the end face of the rotating plate is slidably connected to the bottom of the slide plate.

[0011] Preferably, a sliding groove is provided on the base plate corresponding to the lead screw, and the base plate is slidably connected to the T-block through the sliding groove. Two sets of mounting ears are installed on the left and right side walls of the base plate.

[0012] Preferably, the connecting ring has an L-shaped cross-section, and the fixing frame is slidably connected to the connecting ring through a limiting groove.

[0013] Preferably, a second rubber pad is installed on the end face of the first T-shaped support plate and the second T-shaped support plate.

[0014] Beneficial effects: By setting up an adjustment structure, using a fixed frame, a second motor, a rotating plate, and a connecting ring in cooperation, the rotating plate rotates the clamp, realizing the function of rotating the tee connector. This allows the tee connector to be chamfered at all three ends without multiple disassembly and assembly, avoiding the problem that existing tee chamfering machines have fixed material clamping devices that do not have the function of rotating the tee connector, which makes it necessary to disassemble and assemble the connector multiple times to chamfer the three ends of the tee connector. This improves the chamfering efficiency of the tee connector. Attached Figure Description

[0021] 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.

[0022] Example 1

[0023] This embodiment provides a material clamping device for a three-way chamfering machine, such as Figure 1-5 As shown, the clamping device includes a base plate 1, a first motor 2 is mounted on the front of the base plate 1, a lead screw 3 is provided at the drive end of the first motor 2, a T-block 4 is mounted on the lead screw 3 by a thread, an adjustment structure 5 is mounted on the end face of the T-block 4, and a clamp 6 is mounted on the adjustment structure 5.

[0024] The adjustment structure 5 includes a fixed frame 51 installed on the end face of the T-block 4. A second motor 52 is installed on the inner end face of the fixed frame 51. A rotating plate 53 is installed on the drive end of the second motor 52 and on the upper side of the fixed frame 51. A connecting ring 54 is installed on the bottom of the rotating plate 53. A limit groove 511 is opened on the fixed frame 51 corresponding to the connecting ring 54.

[0025] In use, place the left end of the tee connector at the opening 631, positioning the straight tube of the tee connector between the first arc plate 63 and the second arc plate 65. Drive the knob 641 to rotate the screw 64. The screw 64 drives the second arc plate 65 closer to the connector, working in conjunction with the first arc plate 63 to fix the connector. The first motor 2 drives the lead screw 3 to rotate, which in turn drives the T-block 4 to move. The T-block 4 then drives the adjusting structure 5 to move, which in turn drives the clamp 6 to bring the tee connector closer to the chamfering tool, thus machining one end of the connector. Next, start the second motor 52 to rotate the rotating plate 53. The drive fixture 6 rotates the tee connector 90 degrees, and similarly drives the lead screw 3 to move the T-block 4 back and forth, adjusting the distance between the tee connector and the chamfering tool to chamfer the second end. This process is repeated until all three ends are chamfered, at which point the workpiece can be removed. This achieves the function of rotating the tee connector, allowing the chamfering of all three ends of the connector to be completed without multiple disassembly and reassembly. This avoids the problem of existing tee chamfering machines having fixed material clamping devices that do not have the function of rotating the tee connector, which required multiple disassembly and reassembly of the connector to complete the chamfering of all three ends. This improves the chamfering efficiency of the tee connector.

[0026] In this embodiment, the clamp 6 includes a support plate 61 mounted on the end face of the rotating plate 53 and a fixing plate 62 disposed on the right side of the end face of the rotating plate 53. A first arc-shaped plate 63 is mounted on the upper side of the support plate 61. A screw 64 is mounted on the support plate 61 through a threaded hole. A second arc-shaped plate 65 is rotatably mounted on the end of the screw 64 near the first arc-shaped plate 63 through a bearing. A sliding plate 66 is mounted on the lower side of the second arc-shaped plate 65. An opening 631 is provided on the first arc-shaped plate 63. A first rubber pad 67 is provided on the inner wall of both the first arc-shaped plate 63 and the second arc-shaped plate 65. A knob 641 is provided on the end of the screw 64 away from the second arc-shaped plate 65. The end face of the rotating plate 53 is slidably connected to the bottom of the sliding plate 66.

[0027] In this way, when the first arc plate 63 and the second arc plate 65 clamp the workpiece, the first arc plate 63 and the second arc plate 65 are in flexible contact with the outer wall of the workpiece through the first rubber pad 67, so as to protect the workpiece and avoid damage.

[0028] In this embodiment, a sliding groove 101 is provided on the base plate 1 and corresponding to the lead screw 3. The base plate 1 is slidably connected to the T-block 4 through the sliding groove 101. Two sets of mounting ears 10 are installed on the left and right side walls of the base plate 1. The cross-section of the connecting ring 54 is set with an L-shaped structure. The fixing frame 51 is slidably connected to the connecting ring 54 through the limiting groove 511.

[0029] The connection between the motor shaft and the bottom center of the rotating plate 53 is relatively weak due to the connection of the connecting ring 54 and the limiting groove 511. The rotating plate 53 is slidably connected on the limiting groove 511 by the connecting ring 54, which can improve the installation stability of the rotating plate 53.

[0030] Example 2

[0031] Unlike Embodiment 1, a first T-shaped support plate 7 is installed on the end face of the rotating plate 53 and on both the front and rear sides, and a second T-shaped support plate 8 is installed on the end face of the rotating plate 53 and on the left side of the first T-shaped support plate 7.

[0032] In use, the operator places the outer wall of the third connector of the tee structure into the opening 631 and fits it in place. This allows the straight pipe of the tee connector to fit inside the first arc plate 63 and be placed on the end face of the two sets of first T-shaped support plates 7. The operator only needs to press down on the third connector of the tee connector with one hand to prevent it from tilting upwards during the fixing process. During operation, the operator's other hand drives the screw 64 to rotate through the drive knob 641. The screw 64 drives the second arc plate 65 to move closer to the workpiece and cooperate with the first arc plate 63 to clamp the workpiece. This avoids the problem of having to hold the workpiece with one hand to position it in the traditional workpiece fixing process, thus optimizing the fixing steps, saving physical strength, and making the material clamping device of the tee chamfering machine more effective.

[0033] In this embodiment, a second rubber pad 9 is installed on the end face of the first T-shaped support plate 7 and the second T-shaped support plate 8;

[0034] The second rubber pad 9 protects the workpiece when it is placed on it, preventing it from directly contacting the first T-shaped support plate 7 and the second T-shaped support plate 8 and causing scratches.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
