Definitions

  • Each cover member includes a front [51] Int Cl 2 17/00 plate for covering the front of the slide ways and side [58] Fieid Se a r A 3 5 3 plates extending perpendicularly to the front plate for 1607202 covering the sides of the slide ways.
  • the first cover member is pivoted to the stationary base at one end thereof, and the second cover member is pivoted to [56] References Clad the slide at one end thereof with the other ends of the UN D STATES PATENTS first and second cover members being supported so as 3 282 315 3; j f n to be slidably guided with respect to each other.
  • the present invention relates generally to a cover de- 5 d vice and more particularly to a cover device for covering a slide way.
  • the slideway be covered by a metallic cover member fixed to the slide ,at the upper end thereof and an elastic vinyl seat be fixed to the stationary base at the lower end thereof.
  • the elastic vinyl seat is repeatedly bent each time the slide is forwardly and backwardly moved on the stationary base.
  • the'vinyl seat is liable'to be damaged in a relatively short'time such that its full function cannot be performed.
  • a cover device which includes first and second cover members which are overlapped with each other and are respectively pivoted to a stationary base and a slide each at one end thereof and which are supported so as to be guided with respect to each other at the other ends thereof for covering slide ways which are formed on the slide and stationary base.
  • the first cover member includes a first front plate for covering the front of the slide ways and first side plates extending perpendicularly to the first front plate for covering the sides of the slide ways.
  • the second cover member includes a second front plate for covering the front of the slide way, second side plates extending perpendicularly to the second front plate for covering the sides of the slide ways and guide recesses formed on the second side plates for slidably receiving the first side plates.
  • FIG. 1 is a cross-sectional view showing a cover device according to the present invention
  • FIG. 2 is a front view, partly broken away, taken in the direction of an arrow II of FIG. 1;
  • FIG. 3 is a perspective view showing a first cover
  • FIG. 4 is a perspective view showing a second cover
  • FIG. 5 is a cross-sectional view showing the state of the cover device wherein the slide is in the retracted position.
  • a b'ed l of agrinding machine fixedly mounts thereon a stationary base 2 on which slide ways 4 are formed to slidably mount a wheel slide 3.
  • a grinding wheel 5 is rotatably mounted on the wheel slide 3.
  • a first cover 6 is rotatably mounted on the stationary base 2, and a second cover 10 is rotatably mounted on the wheel slide 3.
  • the first cover 6 includes an arch shape front plate 6a having a curved flange portion 60 on the lower end thereof and a pair of parallel side plates 6b secured perpendicularly to andbackwardly extending from both ends of the archshape front plate 60, as is bestshown in FIG. 3.
  • the curved flange portion 60 is pivoted at both ends thereof by pins 9 which are secured to blocks 8 mounted on the stationary base 2.
  • the second cover 10 includes-an arch. shape front plate 10a and a pair of parallel side plates 10b secured perpendicularly to and backwardly extending from both ends of the arch shape front plate 10a.
  • a guide recess 10c is formed on the inner side of each side plate 10b for slidably receiving each side plate 6b of the first cover 6.
  • the second cover 10 is interposed between side cover members 7 which are fixed to and extend downwardly from both sides of the wheel slide 3 so as to cover the slide ways 4.
  • the second cover 10 is pivoted at the upper portions of side plates 10b by pins 12 which are fixed to blocks 11 formed on the wheel slide 3.
  • a seal member 13 is mounted on the stationary base 2 so as to be held in contact engagement with the outer surface of the curved flange portion 6c to thereby prevent coolant from entering from the lower portion of the first cover 6 into a space which is formed by the first and second covers 6 and 10, the wheel slide 3 and the stationary base 2.
  • FIG. 1 shows a first state of the cover device wherein the wheel slide 3 is in the advanced end position. In such position, the first and the second covers 6 and 10 are inclined, as is shown in FIG. 1.
  • the front portion of the slide ways 4 is covered by the arch shape front plates 6a and 10a, and the side portions of the slide ways 4 are covered by the side plates 6b and 10b.
  • coolant is prevented from entering into the space inside the cover device.
  • first and the second covers slide with respect to each other and are gradually moved into the state shown in FIG. 5.
  • the first cover 6 is then rotated in a clockwise direction about the pin 9 and the second cover 10 is rotated in a clockwise direction about the pin 12.
  • the front and side portions of slide ways 4 are protected by the front plates 6a and 10a, the side plates 6b and 10b, and the seal member 13.
  • the middle and rear portions of the slide ways 4 existing behind the second cover are covered by the side cover members 7.
  • the cover device is durable in comparison with conventional cover devices since it is not constructed by a rubber or vinyl seat. Furthermore, since the free ends of the front plates 6a and 10a are supported so as to be guided with each other, the cover device is automatically extended and contracted in accordance with the movement of the wheel slide 3 relative to the stationary base 2. Thus, the movement of the wheel slide 3 is not affected by the cover device. Since the side plates 6b and 10b are overlapped with each other at the sides of the slide ways 4, the sides of the slide ways 4 are covered by either the plate 6b and 10b, such that coolant is prevented from entering inside the cover device.
  • a coverdevice for covering slide ways formed on a stationary base and a slide comprising:
  • first cover member rotatably mounted on said stationary base, said firstcover member comprising a first front plate for covering the front of said slide ways and first side plates extending perpendicularly to said first front plate for covering the sides of said slide ways, and
  • a cover device rotatably mounted on said slide, said second cover member comprising a second front plate for covering the front of said slide ways, second side plates extending perpendicularly to said second front plate for covering the sides of said slide ways and guide recesses formed onsaid 3.
  • said I first front plate has a curved flange portion, said curved flange portion being rotatably connected to said stationary base by a pin.
  • a cover device further com-, prising a seal member fixed to said stationary base at one end thereof and held in contact engagement with said curved flange portion at the other end thereof.
  • a cover device according to claim 1, further comi prising side cover members mounted on both sides of said slide, and said first and said second covers being received between said side cover members.
