Description

Technical Field

[0001] This utility model belongs to the field of combined machine tool technology, and in particular relates to a quick-release structure for a transmission lead screw of a combined machine tool. Background Technology

[0002] A machine tool lead screw, also simply called a lead screw or lead screw, is a helical mechanical component used in machine tools to transmit motion and power. It typically consists of two parts: a lead screw (screw) and a nut, which achieve the conversion between rotary motion and linear motion through the threaded engagement between them.

[0003] Existing lead screws are usually mounted on a connecting seat on the machine tool base and connected to the connecting seat by bearings. After the lead screw is fitted into the bearing and installed to the connecting seat through the bearing, the lead screw is firmly fixed, making it difficult to disassemble during subsequent maintenance work. Furthermore, the disassembly process is obstructed by other parts of the machine tool, making the disassembly process difficult and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release structure for a transmission lead screw in a combination machine tool. By setting a quick-release component, specifically by removing the bolts on the connecting seat to loosen it, and then rotating the rotating rod clockwise to drive the threaded rod to rotate as well, the connecting plate drives the push block to move via the pull rod. At this time, the push block pulls the connecting seat, allowing the lead screw to smoothly disengage from the tailstock. Once the lead screw is disengaged from the tailstock, the connecting seat and the lead screw can be removed together, thus quickly completing the disassembly. The operation is simple and convenient, solving the problems of existing lead screws being difficult to disassemble during maintenance, and being obstructed by other parts of the machine tool during the disassembly process, making the disassembly process difficult and inefficient.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a quick-release structure for a transmission lead screw in a combination machine tool, comprising a base, a lead screw disposed on the inner side of the top of the base, a quick-release assembly disposed on the left side of the lead screw, a tailstock mounted on the right side of the lead screw via a bearing, and the bottom of the tailstock mounted on the base via bolts. The quick-release assembly includes a connecting plate, a threaded rod threadedly connected to the center of the connecting plate, a rotating rod fixedly connected to the left side of the threaded rod, two pull rods fixedly connected to the right side of the connecting plate, and push blocks fixedly connected to the right side of each of the two pull rods. A connecting seat is mounted on the left side of the lead screw via a bearing, and the bottom of the connecting seat is mounted on the base via bolts. The pull rods connect the connecting plate and the push blocks by welding, and both ends are supported by bolts.

[0007] Furthermore, a threaded ring is threaded onto the outer surface of the left side of the lead screw. After the threaded ring is installed on the lead screw, it contacts the left side of the connecting seat. A pushing component is provided on the left side of the connecting seat. The threaded ring is used to lock the lead screw onto the connecting seat, so that the lead screw can be pulled out smoothly when the connecting seat is disassembled.

[0008] Furthermore, the connecting plate has two sliding holes inside, and a sliding rod is slidably connected inside each of the two sliding holes. The right side of the sliding rod is fixedly connected to the left side of the base, and the right side of the threaded rod contacts the left surface of the base. The push block is located on the right side of the connecting seat, and the push block contacts the corresponding side of the connecting seat. Since the connecting plate slides on the sliding rod through the sliding holes, the connecting plate can avoid tilting when the connecting seat is pulled, making the movement of the connecting plate more stable and linear.

[0009] Furthermore, the pushing assembly includes a fixed frame fixedly connected to the left side of the connecting seat. A threaded rod two is threadedly connected inside the fixed frame. A push shaft is fixedly connected to the right side of the threaded rod two, and an external hexagonal block is fixedly connected to the left side of the threaded rod two. The right side of the push shaft contacts the left side of the lead screw. The diameter of the push shaft is smaller than the diameter of the lead screw. Because the diameter of the push shaft is smaller than the diameter of the lead screw, the lead screw can be smoothly pushed out of the connecting seat.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model features a quick-release assembly. Specifically, the bolts on the connecting seat are removed, loosening the connecting seat. Then, the rotating rod is rotated clockwise, causing the threaded rod to rotate as well. The connecting plate then moves the push block via the pull rod. At this time, the push block pulls the connecting seat, allowing the lead screw to smoothly disengage from the tailstock. Once the lead screw is disengaged from the tailstock, the connecting seat and lead screw can be removed together, thus quickly completing the disassembly. The operation is simple and convenient.

[0012] 2. This utility model, by setting up a pushing component, specifically disassembles the threaded ring, releases the locking of the lead screw, and then uses a wrench or other tools to drive the threaded rod two clockwise through the external hexagonal block, so that the push shaft pushes the lead screw until the lead screw is pushed away from the connecting seat. At this point, the lead screw can be completely disassembled, which saves time and effort and improves disassembly efficiency.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5As shown, this utility model is a quick-release structure for a transmission lead screw of a combination machine tool, including a base 1, a lead screw 11 disposed on the inner side of the top of the base 1, a quick-release assembly 12 disposed on the left side of the lead screw 11, and a tailstock 111 mounted on the right side of the lead screw 11 via a bearing. The bottom of the tailstock 111 is bolted to the base 1. The quick-release assembly 12 includes a connecting plate 121, a threaded rod 122 threadedly connected to the center of the connecting plate 121, a rotating rod 123 fixedly connected to the left side of the threaded rod 122, and two pull rods 125 fixedly connected to the right side of the connecting plate 121. Push blocks 1 are fixedly connected to the right side of each of the two pull rods 125. 26. A connecting seat 112 is mounted on the left side of the lead screw 11 via a bearing. The bottom of the connecting seat 112 is bolted to the base 1. Remove the bolts on the connecting seat 112 to loosen it. Then rotate the rotating rod 123 clockwise and drive the threaded rod 122 to rotate together. The connecting plate 121 drives the push block 126 to move via the pull rod 125. At this time, the push block 126 pulls the connecting seat 112, so that the lead screw 11 can be smoothly disengaged from the tailstock. After the lead screw 11 is disengaged from the tailstock, the connecting seat 112 and the lead screw 11 can be removed together, thus quickly completing the disassembly. The operation is simple and convenient.

[0024] A threaded ring 113 is threadedly connected to the outer surface of the left side of the lead screw 11. After the threaded ring 113 is installed on the lead screw 11, it contacts the left side of the connecting seat 112. A push assembly 13 is provided on the left side of the connecting seat 112.

[0025] The connecting plate 121 has two sliding holes 211 inside. The sliding rods 124 are slidably connected inside the two sliding holes 211 on the connecting plate 121. The right side of the sliding rod 124 is fixedly connected to the left side of the base 1. The right side of the threaded rod 122 is in contact with the left surface of the base 1. The push block 126 is located on the right side of the connecting seat 112, and the push block 126 is in contact with the corresponding side of the connecting seat 112.

[0026] The pushing assembly 13 includes a fixed bracket 131 fixedly connected to the left side of the connecting seat 112. A threaded rod 132 is threadedly connected inside the fixed bracket 131. A push shaft 133 is fixedly connected to the right side of the threaded rod 132. An external hexagon block 134 is fixedly connected to the left side of the threaded rod 132. The right side of the push shaft 133 contacts the left side of the lead screw 11. The diameter of the push shaft 133 is smaller than the diameter of the lead screw 11. The threaded ring 113 is removed to release the locking of the lead screw 11. Then, a wrench or other tools are used to drive the threaded rod 132 to rotate clockwise through the external hexagon block 134, so that the push shaft 133 pushes the lead screw 11 until the lead screw 11 is pushed away from the connecting seat 112. At this time, the lead screw 11 can be completely disassembled, which saves time and effort and improves disassembly efficiency.

[0027] One specific application of this embodiment is:

[0028] When it is necessary to disassemble the lead screw 11, first remove the bolts on the connecting seat 112 to loosen the connecting seat 112. Then rotate the rotating rod 123 clockwise so that the threaded rod 122 contacts the left side of the base 1. With continuous rotation, the connecting plate 121 moves to the left and slides on the sliding rod 124 through the sliding hole 211, making the connecting plate 121 move in a straight line and making the movement of the connecting plate 121 more stable. The connecting plate 121 then drives the push block 126 to move through the pull rod 125. At this time, the push block 126 pulls the connecting seat 112. Since the lead screw 11 is locked on the connecting seat 112 by the threaded ring 113, the movement of the connecting seat 112 will drive the lead screw 11 to move together, so that the lead screw 11 can be smoothly disengaged from the tail seat. After the lead screw 11 is disengaged from the tail seat, the connecting seat 112 and the lead screw 11 can be taken out together, thus quickly completing the disassembly. The operation is simple and convenient.

[0029] After the connecting seat 112 and the lead screw 11 are removed, the threaded ring 113 is disassembled to release the lock of the lead screw 11. Then, using a wrench or other tools, the threaded rod 132 is rotated clockwise by the external hexagon block 134, so that the push shaft 133 contacts the left side of the lead screw 11. Through continuous rotation, the push shaft 133 pushes the lead screw 11 until the lead screw 11 is pushed away from the connecting seat 112. At this point, the lead screw 11 can be completely disassembled. This not only saves time and effort, but also avoids the impact of machine tool obstruction.
