Abstract
Description
Technical Field
[0001] This utility model belongs to the field of machine tool guide rail connection technology, specifically a connection structure for machine tool linear guide rails. Background Technology
[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, and other types.
[0003] Currently, when installing linear guides, the problem of insufficient guide length may occur. In this case, the guides need to be spliced. Traditional guide splicing is usually done manually by aligning them and then tightening bolts to fix the positions of the two guides. However, when tightening the bolts, the guides will inevitably shift, which will affect the connection effect of the two guides. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a connection structure for machine tool linear guides, which solves the problem that traditional guide rail splicing usually involves manual alignment, followed by tightening bolts to fix the positions of the two guide rails. However, when tightening the bolts, the guide rails inevitably shift, thus affecting the docking effect of the two guide rails.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for a machine tool linear guide, comprising a guide body and a connecting seat, wherein the guide body is mounted on the connecting seat by bolts, the connecting seat has multiple connecting holes on its upper side, a snap-fit block is connected to one side of the connecting seat, an fitting groove is provided on the other side of the connecting seat, side plates are connected to both sides of the upper side of the connecting seat, and multiple fixing blocks are connected to the connecting seat;
[0006] A threaded rod is threadedly connected to one side plate of the connecting seat. A handwheel is connected to one end of the threaded rod, and a movable plate is rotatably connected to the other end of the threaded rod. A guide rod is connected to the movable plate, and two first locking blocks are connected to the movable plate. Two second locking blocks are connected to the other side plate of the connecting seat.
[0007] As a further embodiment of this utility model: the guide rail body is provided with a plurality of mounting holes, and the guide rail body is provided with slots at both ends, and the mounting holes and the connecting holes are of the same size and correspond to each other in position.
[0008] As a further embodiment of this utility model: rubber pads are connected to the opposite sides of the first and second card blocks, and both the first and second card blocks are fitted into the card slots.

[0010] As a further embodiment of this utility model: a first threaded hole is provided on one side of the connecting seat, and a second threaded hole is provided on the snap-fit block. The first threaded hole and the second threaded hole are the same size and are threadedly connected to a fastening screw. The snap-fit block is engaged with the fitting groove.
[0011] As a further embodiment of this utility model: the snap-fit block is engaged with the fitting groove, and two guide rods are respectively disposed on both sides of the threaded rod, and the guide rods are slidably connected to the side plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. The connection structure of the linear guide rail of this machine tool is provided with a slot, a first locking block, a second locking block, a handwheel, a threaded rod, and a movable plate. The operator places the two guide rail bodies together on the connecting seat, so that the two second locking blocks are respectively locked into the slots on one side of the two guide rail bodies. Then, the operator turns the handwheel to rotate the threaded rod, which causes the threaded rod to push the movable plate to move, so that the two first locking blocks are respectively locked into the slots on the other side of the two guide rail bodies. The movable plate and the side plate on one side of the connecting seat clamp and fix the two guide rail bodies, thereby preventing the two guide rail bodies from moving or shifting when the bolts are tightened, and improving the splicing effect of the two guide rail bodies.
[0014] 2. The connection structure of the linear guide rail of this machine tool, by setting a snap-fit block, a fitting groove, a first threaded hole, a second threaded hole and a fastening screw, allows the operator to snap the snap-fit block on one side of a connecting seat into the fitting groove on the other side of a connecting seat. At this time, the first threaded hole and the second threaded hole will be aligned with each other, which makes it convenient for the operator to screw in the fastening screw for connection and fixation. The operation is simple and convenient for the operator to splice the connecting seats, thereby adapting to the need for longer processing strokes. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a connection structure for a machine tool linear guide, including a guide body 1 and a connecting seat 2. The guide body 1 is mounted on the connecting seat 2 by bolts. The guide body 1 has multiple mounting holes 101 and slots 102 at both ends. The mounting holes 101 and the connecting holes 3 are the same size and correspond in position. The operator can install and fix the guide body 1 on the connecting seat 2 by screwing bolts into both the mounting holes 101 and the connecting holes 3. The operation is convenient and improves the stability of the guide body 1 during operation.
[0022] Multiple connection holes 3 are provided on the top of the connector 2. A snap-fit block 4 is connected to one side of the connector 2, and a fitting groove 5 is provided on the other side of the connector 2. A first threaded hole 16 is provided on one side of the connector 2, and a second threaded hole 17 is provided on the snap-fit block 4. The first threaded hole 16 and the second threaded hole 17 are the same size and are threadedly connected to a fastening screw 18. The snap-fit block 4 and the fitting groove 5 are engaged. Through the engagement of the snap-fit block 4 and the fitting groove 5, the workers can quickly complete the docking of the two connectors 2, thereby improving the splicing efficiency.
[0023] Side plates 6 are connected to the upper two sides of the connecting seat 2. Multiple fixing blocks 7 are connected to the connecting seat 2. There are four fixing blocks 7 arranged in a rectangular array on the connecting seat 2. Fixing holes 15 are opened on the fixing blocks 7. By screwing bolts into the fixing holes 15 on the fixing blocks 7, the connecting seat 2 can be fixed to the worktable of the machine tool, thereby preventing the connecting seat 2 from slipping during operation.
[0024] A threaded rod 8 is threadedly connected to a side plate 6 on one side of the connecting seat 2. A handwheel 9 is connected to one end of the threaded rod 8, and a movable plate 10 is rotatably connected to the other end of the threaded rod 8. A guide rod 11 is connected to the movable plate 10. There are two guide rods 11, which are respectively set on both sides of the threaded rod 8. The guide rods 11 are slidably connected to the side plate 6. When the threaded rod 8 is turned to push the movable plate 10 to move, the guide rods 11 will slide on the side plate 6 on one side of the connecting seat 2, thereby restricting the movable plate 10 and preventing the movable plate 10 from rotating and deviating.
[0025] Two first locking blocks 12 are connected to the movable plate 10, and two second locking blocks 13 are connected to the side plate 6 on the other side of the connecting seat 2. Rubber pads 14 are connected to the opposite side of the first locking blocks 12 and the second locking blocks 13. The first locking blocks 12 and the second locking blocks 13 are fitted into the slots 102. When the movable plate 10 clamps and fixes the guide rail body 1, the rubber pads 14 on the first locking blocks 12 and the second locking blocks 13 will be squeezed and deformed, thereby buffering the contact and avoiding excessive contact impact that could cause damage.
[0026] The working principle of this utility model is as follows:
[0027] The worker places two guide rail bodies 1 together on the connecting seat 2, so that the joint of the two guide rail bodies 1 contacts the side plate 6 on one side of the connecting seat 2. This causes the two second locking blocks 13 to respectively engage in the locking grooves 102 on one side of the two guide rail bodies 1. Then, the worker turns the handwheel 9 to rotate the threaded rod 8, causing the threaded rod 8 to push the movable plate 10 to move. At this time, the guide rod 11 will slide on the side plate 6, thereby causing the two first locking blocks 12 to respectively engage in the locking grooves 102 on the other side of the two guide rail bodies 1. The movable plate 10 and the side plate 6 on one side of the connecting seat 2 are used to clamp and fix the two guide rail bodies 1, thereby preventing the two guide rail bodies 1 from shifting when the bolts are turned, thus improving the splicing effect of the two guide rail bodies 1.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
