Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment, specifically a Y-axis protection structure for a moving column vertical machining center. Background Technology

[0002] Vertical machining centers come in a variety of structures. Currently, the main structures of vertical machining centers include traditional C-type vertical machining centers, moving column vertical machining centers, and small gantry vertical machining centers.

[0003] Currently, high-protection vertical machining centers with moving columns generally use a full-wall protective cover to separate the machining area from the non-machining area. The Y-axis generally uses a scraper structure to remove chips from the spindle box.

[0004] However, in traditional scraper structures, the scraper not only needs to scrape off chips, but also needs to bear the weight of the Z-axis guard, resulting in poor reliability and lifespan. At the same time, there are gaps between the scrapers, which cannot completely prevent powder from entering non-processing areas when processing non-metallic materials such as graphite. Utility Model Content

[0005] The purpose of this utility model is to provide a Y-axis protective structure for a moving column vertical machining center, in order to solve the problems mentioned in the background art. In the traditional scraper structure, the scraper not only needs to scrape off chips, but also needs to bear the weight of the Z-axis guard, resulting in poor reliability and lifespan. At the same time, there are gaps between the scrapers, which cannot completely prevent powder from entering the non-processing area when processing non-metallic materials such as graphite.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Y-axis protective structure for a moving column vertical machining center, comprising: a spindle box, a first protective cover fixing plate and a second protective cover fixing plate, two symmetrically arranged linear guides fixedly installed on the top of the spindle box, two symmetrically arranged linear guides respectively installed on the side of the spindle box, a slider fixedly installed on the upper surface of the linear guide, and a fixing block fixedly installed on the upper surface of the slider;

[0007] Bellows covers are fixedly installed at both ends of the first and second protective cover fixing plates, and an air duct is fixedly installed on the lower surface of the spindle box. A dust inlet is provided at the front end of the air duct, and a dust collector interface is provided at the rear end of the air duct.

[0008] Preferably, the first protective cover fixing plate is fixedly connected to four sliders on the spindle box by a fixing block.

[0009] Preferably, the second protective cover fixing plate is fixedly installed at the front end of the spindle box, the spindle body is fixedly installed on the lower surface of the front end of the spindle box, and the dust inlet is close to the spindle body.

[0010] Preferably, the slider drives the first protective cover fixing plate to move in the same direction through the moving position of the spindle box.

[0011] Preferably, the bellows cover covers the outer surface of the spindle box and the air duct.

[0012] Preferably, the first protective cover fixing plate drives the accordion cover to slide along the spindle box in a direction that moves closer to or further away from each other through the sliding cooperation of the linear guide rail and the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a Y-axis protection structure for a moving column vertical machining center;

[0015] By replacing the traditional scraper-type Y-axis guard with an accordion-type guard, and fixing the two ends of the accordion-type guard to a first guard fixing plate and a second guard fixing plate respectively, the first guard fixing plate is fixedly connected to four sliders on the spindle box via fixing blocks. The weight of the first guard fixing plate is supported by linear guides. When the spindle box moves up, down, left, or right for machining, the sliders move the first guard fixing plate, and the second guard fixing plate moves with the spindle box. Since the linear guides fully support the weight of the first guard fixing plate, compared to the traditional scraper structure which also needs to bear the weight of the guard... The reduced weight effectively extends the service life of the bellows cover and reduces production costs to some extent. While preventing dust from entering non-processing areas, the bottom of the spindle box is fixedly connected to the air duct, with the front end of the duct serving as the dust inlet and the rear end as the dust collector interface. Dust is collected during processing, and the dust inlet moves with the spindle. Because the dust inlet is close to the spindle, the dust generated during processing is collected centrally through the dust collector's output. Furthermore, the bellows cover completely encloses the spindle box and air duct, effectively preventing dust from entering non-processing areas and improving the protection of the spindle box.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a Y-axis protection structure for a moving column vertical machining center;

[0024] Example 1:

[0025] To extend the lifespan of the Y-axis guard, two symmetrically arranged linear guides 3 are fixedly installed on the top of the spindle box 1, and two symmetrically arranged linear guides 3 are installed on the sides of the spindle box 1. A slider 4 is fixedly installed on the upper surface of each linear guide 3, and a fixing block 8 is fixedly installed on the upper surface of each slider 4. The first guard fixing plate 6 is fixedly connected to the four sliders 4 on the spindle box 1 via the fixing blocks 8. The sliders 4 move in the same direction as the spindle box 1. The first guard fixing plate 6 moves in the same direction as the spindle box 1, and the sliding contact between the linear guides 3 and the sliders 4 causes the bellows guard 2 to slide along the spindle box 1 in directions that are closer to or further away from each other. The traditional Y-axis guard is replaced by an accordion guard 2. The two ends of the accordion guard 2 are fixed to the first guard fixing plate 6 and the second guard fixing plate 7 respectively. The first guard fixing plate 6 is fixedly connected to the four sliders 4 on the spindle box 1 through the fixing block 8. The weight of the first guard fixing plate 6 is supported by the linear guide rail 3. When the spindle box 1 moves up, down, left, and right for processing, the sliders 4 drive the first guard fixing plate 6 to move, and the second guard fixing plate 7 moves with the spindle box 1. Since the linear guide rail 3 fully supports the weight of the first guard fixing plate 6, compared with the traditional scraper structure which also needs to bear the weight of the guard, the service life of the accordion guard 2 is effectively improved.

[0026] Example 2:

[0027] To improve the protective effect of the Y-axis shield based on Embodiment 1, accordion shields 2 are fixedly installed at both ends of the first shield fixing plate 6 and the second shield fixing plate 7, respectively. An air duct 10 is fixedly installed on the lower surface of the spindle box 1, with a dust inlet 9 at the front end and a dust collector interface 11 at the rear end. The second shield fixing plate 7 is fixedly installed at the front end of the spindle box 1, and the spindle body 5 is fixedly installed on the lower surface of the front end of the spindle box 1. The dust inlet 9 is located near the spindle body 5. The bellows cover 2 covers the outer surface of the spindle box 1 and the air duct 10. Since the bottom of the spindle box 1 is fixedly connected to the air duct 10, and the front end of the air duct 10 is the dust inlet 9 and the rear end is the dust collector interface 11, dust is collected during processing. The dust inlet 9 moves with the spindle. Since the dust inlet 9 is close to the spindle, the dust generated during processing enters through the dust inlet 9 through the output of the dust collector and is collected in a concentrated manner. The bellows cover 2 completely covers the spindle box 1 and the air duct 10, which can completely prevent dust from entering the non-processing area.

[0028] Working Principle: In actual use, to improve the service life of the Y-axis guard, the traditional scraper guard is replaced with an accordion guard 2. The two ends of the accordion guard 2 are fixed to the first guard fixing plate 6 and the second guard fixing plate 7, respectively. The first guard fixing plate 6 is fixedly connected to four sliders 4 on the spindle box 1 via fixing blocks 8. The weight of the first guard fixing plate 6 is supported by linear guide rails 3. When the spindle box 1 moves up, down, left, or right during machining, the sliders 4 move the first guard fixing plate 6, and the second guard fixing plate 7 moves with the spindle box 1. Because the linear guide rails 3 fully support the weight of the first guard fixing plate 6, compared to the traditional… The scraper structure also needs to bear the weight of the cover, which effectively improves the service life of the bellows cover 2 and reduces production costs to a certain extent. In order to improve the protective effect of the Y-axis cover, since the bottom of the spindle box 1 is fixedly connected to the air duct 10, and the front end of the air duct 10 is the dust inlet 9 and the rear end is the dust collector interface 11, dust is collected during processing. The dust inlet 9 moves with the spindle. Since the dust inlet 9 is close to the spindle, the dust generated during processing enters the dust inlet 9 through the output of the dust collector and is collected in a concentrated manner. The bellows cover 2 completely covers the spindle box 1 and the air duct 10, which can completely prevent dust from entering the non-processing area and improve the protective effect of the spindle box 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
