Description

Tight-pushing type driving device

Technical Field

The utility model relates to a cutting off machine tool technique, concretely relates to tight formula drive arrangement in top.

Background

The transverse shaft moving driving device of the cutting machine is a structure which drives a gear to be meshed with a rack through a motor. The movement of a transverse shaft, namely an X shaft, on the cutting machine is transmitted through a gear rack with general precision, the moving distance is long, the meshing of the gear rack needs to ensure good clearance to realize smooth transmission, if the clearance is too large, the impact force of the gear to the rack is large, so that the movement is not stable, and if the clearance is too small, the gear is easy to clamp, so that the motor is damaged in an idling mode.

For the gear rack long distance transmission with general precision on the cutting machine, a laterally arranged tension spring is usually adopted to pull a fixed plate of a speed reducer so as to ensure the meshing clearance of a gear rack and ensure that the speed reducer, the fixed plate, a gear and the like smoothly move along with a transverse shaft. The side tension spring causes uneven stress between the gear and the rack, the problems of unsmooth sliding, blocked return and the like can occur during reciprocating movement, and the tension force of the tension spring can also cause the defects of upward warping of a speed reducer fixing plate and poor verticality of the gear and the rack. The problem of poor meshing of the gear and the rack is aggravated because the tension spring is elastically deformed and fails after long-time working.

Disclosure of Invention

In order to solve the problem, the utility model provides a push up tight formula drive arrangement can adjust the backlash in a flexible way, improves the smooth and easy of drive arrangement removal to simple to operate, long service life. The utility model adopts the technical scheme as follows:

the jacking driving device comprises a horizontally arranged L-shaped seat plate and a fixing plate for mounting a speed reducer, wherein the fixing plate is arranged above the seat plate, the left side surface of the fixing plate is horizontally provided with at least one pressure spring, the right end of the pressure spring is arranged in the side surface of the fixing plate, and the left end of the pressure spring is fixedly arranged on the seat plate.

In the jacking driving device, the sliding block is arranged on the bottom surface of the fixed plate, and the linear guide rail in sliding fit with the sliding block is arranged on the seat plate.

According to the jacking type driving device, the left end of the pressure spring is connected with the jacking bolt, the jacking bolt is fixed on the jacking pressing plate, and the jacking pressing plate is fixedly arranged on the seat plate.

The utility model has the advantages that: the traditional tension spring is changed into a pressure spring, so that the installation and adjustment are convenient, and the problem that the stretching deformation driving device cannot return is avoided. The direction of the jacking force of the pressure spring is perpendicular to the moving direction, the stress at the meshing part is uniform, the fixed plate cannot upwarp, the clamping stagnation phenomenon is avoided, and the moving operation is stable.

Drawings

Fig. 1 is a schematic front view of an embodiment of the present invention;

fig. 2 is a schematic top view of an embodiment of the present invention.

In the figure: the device comprises a motor 1, a speed reducer 2, a fixing plate 3, a linear guide rail 4, a seat plate 5, a vertical plate 6, a rack 7, a gear 8, a jacking pressure plate 9, a jacking bolt 10 and a compression spring 11.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The utility model provides a top compact form drive arrangement, includes the bedplate 5 of the L type that the level set up and the fixed plate 3 that is used for installing speed reducer 2, fixed plate 3 establishes the top at bedplate 5, the left surface level of fixed plate 3 is equipped with at least one pressure spring 11, the right-hand member of pressure spring 11 is established in fixed plate 3 side, the left end is established on bedplate 5 admittedly. In the embodiment, two groups of pressure springs 11 are arranged, the right side of the seat plate 5 is arranged on the vertical plate 6, and the lower end of the vertical plate 6 is provided with a slide rail for facilitating the movement of the cross shaft. Referring to fig. 1, a motor 1 is driven to a gear 8 through a speed reducer 2, the gear 8 is meshed with a rack 7, and a pressure spring 11 is arranged on the opposite side of the meshing to realize the function of jacking.

In the jacking driving device, the sliding block is arranged on the bottom surface of the fixed plate 3, and the linear guide rail 4 in sliding fit with the sliding block is arranged on the seat plate 5. The linear guide 4 is convenient for on the one hand, the speed reducer 2 slides and improves the adjustment sensitivity of the meshing gap, and on the other hand, the linear guide can play a limiting role and avoid the fixed plate 3 from upwarping.

In the jacking driving device, the left end of the pressure spring 11 is connected with the jacking bolt 10, the jacking bolt 10 is fixed on the jacking pressing plate 9, and the jacking pressing plate 9 is fixedly arranged on the seat plate 5. The jacking force of the jacking bolt 10 can be correspondingly adjusted according to different gear racks, so that a proper meshing gap is achieved. The operating principle of the jacking type driving is as follows: a certain meshing force exists between the gear 8 and the rack 7, the pressure spring 11 is compressed if the meshing force is too tight, and the pressure spring 11 extends to apply elastic force to the fixing plate 3 if the meshing force is too small, so that the uniform stress of the meshing position is ensured.
