Description

Technical Field

[0001] The utility model belongs to the technical field of optical axis guide rails, and particularly relates to an optical axis guide rail anti-dropping fixing structure. Background Art

[0002] The optical axis guide is a rolling guide, which is composed of rolling steel balls that make infinite reciprocating motion between the slider and the guide, and the load platform easily makes linear motion with high precision along the track. Compared with the traditional machine tool guide, the friction coefficient of the rolling guide can be reduced to 1 / 50 of the original. Since the starting friction is greatly reduced, the occurrence of invalid motion is relatively reduced, so high-precision feeding and positioning can be achieved. Therefore, it can be used with ball screws and cylinders as drives, and optical axis guides as guides, which will greatly improve the accuracy and mechanical efficiency of the equipment and are widely used in automated mechanical equipment.

[0003] The optical axis guide rail has the advantages of simple installation, fast and smooth operation, strong weather resistance, not easy to accumulate dust, easy to clean, and convenient disassembly and maintenance. However, due to the continuous increase in operating speed, the fixed end of the optical axis is prone to fatigue loosening or even decoupling, increasing the mechanical failure rate.

[0011] Furthermore, the fixing seat is a "convex" shaped structure, and the shaft hole is arranged in the middle of the fixing seat.

[0012] Furthermore, the inner diameter of the shaft hole is equal to the outer diameter of the optical axis connecting portion.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] A typical implementation of the utility model is a structure for fixing an optical axis guide rail to prevent it from falling off, such as Figure 1 As shown, it includes an optical axis 1 and a fixing seat 2, the fixing seat 2 is arranged at one end of the optical axis 1, and the outer surface of the optical axis 1 is stepped, as shown in FIG. Figure 2As shown, it includes a connecting part 3 and a sliding part 4, the connecting part 3 is arranged at one end of the sliding part 4, a sliding block 5 is sleeved on the outer side of the sliding part 4, the sliding block 5 is slidably connected to the sliding part 4, and a plurality of screw holes are arranged on the sliding block 5, so that the sliding block 5 can be fixed on the frame of the equipment by screws.

[0025] The cross-sectional diameter of the connecting portion 3 is smaller than the cross-sectional diameter of the sliding portion 4 . The length of the connecting portion 3 is the same as the width of the fixing seat 2 . The optical axis 1 is fixedly connected to the fixing seat 2 via the connecting portion 3 .

[0026] The fixing base 2 is a "convex" shaped structure, and a plurality of bolt holes are symmetrically arranged at both ends of the fixing base 2. The fixing base 2 can be fixed to the functional component 6 of the equipment by bolts, thereby realizing the sliding of the functional component 6 on the frame.

[0027] like Figure 3 As shown, an axial hole 7 is provided in the middle of the fixing seat 2, and the inner diameter of the axial hole 7 is equal to the outer diameter of the connecting portion 3 of the optical axis 1, so that the connecting portion of the optical axis 1 can be inserted into the axial hole 7. Since the cross-sectional diameter of the connecting portion 3 is smaller than the cross-sectional diameter of the sliding portion 4, the fixing seat 2 is prevented from moving toward the sliding portion 4.

[0028] In order to prevent the optical axis 1 and the fixed seat 2 from disengaging under conditions of reciprocating motion and collision and vibration, a fine internal thread is provided on the inner wall of the shaft hole 7, and a fine external thread is provided on the outer surface of the connecting part 3 of the optical axis 1. The fine internal thread is adapted to the fine external thread, thereby realizing a threaded connection between the optical axis 1 and the fixed seat 2, and improving the stability of the connection between the optical axis 1 and the fixed seat 2.

[0029] Furthermore, a clamping gap 8 is provided above the shaft hole 7, and the side walls of the shaft hole 7 on both sides of the clamping gap 8 are connected by a plurality of locking bolts 9. Specifically, a plurality of threaded holes are arranged side by side on the side walls of the shaft hole 7 on one side of the clamping gap 8, and a plurality of through holes are arranged side by side on the side walls of the shaft hole 7 on the other side of the clamping gap 8, and the plurality of threaded holes are arranged in one-to-one correspondence with the plurality of through holes, and the locking bolts 9 pass through the through holes on one side and are threadedly connected with the threaded holes on the other side, and when the locking bolts 9 are tightened, the side walls of the shaft hole 7 on both sides of the clamping gap 8 are close to each other, thereby clamping the optical axis 1 placed in the shaft hole 7 of the fixing seat 2, so that the fixing seat 2 firmly holds the optical axis 1, thereby preventing the optical axis from falling off.

[0030] The utility model processes mutually matching threads at the connection between the optical axis and the fixing seat, and when the optical axis is screwed into the optical axis fixing seat, a large axial stabilizing force is generated, thereby increasing the connection stability between the optical axis and the fixing seat; at the same time, a clamping gap is opened above the shaft hole, and a locking bolt is used for locking. When the locking bolt is locked, a larger locking force is generated, so that the optical axis fixing seat firmly holds the optical axis, thereby solving the problem that the optical axis is easy to fall off.

[0031] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
