[0032] See also Figure 1-4 An electric spark machine bed comprises a machine bed 1, side connecting parts 2, a rear protective part 3 and a front end sealing part 4. The side connecting parts 2 are symmetrically arranged on the machine bed 1. The rear protective part 3 comprises a base 31 arranged between the side connecting parts 2. A cover body 32 is arranged on the base 31. One end of the cover body 32 extends between the side connecting parts 2. The front end sealing part 4 is arranged between the side connecting parts 2, and the front end sealing part 4 is in close contact with the machine bed 1.

[0033] The existing machine tool body is mainly composed of a bed frame, guide rails, a bed lubrication system and bed accessories made of cast iron parts. The present embodiment is based on the Y-axis feed guide rail of the machine tool body. The side connecting member 2 is installed close to the guide rail of the machine tool bed 1, and the side connecting member 2 is located below the X-axis feed guide rail part above the machine tool bed 1. Then, the base 31 and the side connecting member 2 are connected close to the spindle box of the machine tool bed 1, and the cover body 32 is placed between the side connecting members 2 to connect with the X-axis feed guide rail part. Finally, it is combined with the side connecting member 2 through the front end sealing member 4 to form the outer protective component of the Y-axis feed guide rail of the machine tool body.

[0034] Based on the above, the rear protective part 3 and the front end sealing part 4 are installed on the front and rear of the Y-axis feed guide rail on the machine tool bed 1 through the cooperation of the side connecting part 2 and the machine tool bed 1, and a protective component that is easy to disassemble and assemble is formed outside the guide rail and the feed device, which is convenient for internal inspection and ensures stable machine tool feeding.

[0035] See also Figure 1-4 The side connecting member 2 includes a cover plate 21, a hanging part 22 and a slide rail part 23. The slide rail part 23 is arranged on the cover plate 21 from top to bottom. The slide rail part 23 and the hanging part 22 are arranged on the cover plate 21 on the same side. The slide rail part 23 is located on the hanging part 22. Slide grooves are provided on the upper and lower sides of the machine tool bed 1. The hanging part 22 can be moved along the slide grooves and is arranged on the machine tool bed 1. The cover plate 21 is located on the side of the machine tool bed 1.

[0036] The rear protective part 3 and the front end sealing part 4 are installed on the above-mentioned side connecting part 2 in cooperation with the machine tool bed 1, and front and rear through-going slide grooves are set through the upper end face and the lower side of the machine tool bed 1. The operating cover plate 21 pushes the hanging part 22 into the slide groove and moves along the slide groove on the side of the machine tool bed 1 until the cover plate 21 is flush with the end face of the machine tool bed 1 and stops moving, and the follow-up slide rail part 23 is located above the machine tool bed 1.

[0037] It should be noted that the cover plate 21 is installed by connecting the hanging part 22 with the slide groove. The hanging part 22 can adopt a hook set at a right angle, which is connected with the slide groove with a rectangular upper cross-section and an L-shaped lower cross-section. However, the cover plate 21 is hung outside the machine tool bed 1.

[0038] See also Figure 1-4 The base 31 is symmetrically provided with protrusions, and the base 31 is arranged between the slide rail parts 23 through the protrusions. The cover body 32 includes a cover plate 321 arranged on the base 31, and the cover plate 321 is symmetrically provided with connecting heads 322. The cover plate 321 is located between the slide rail parts 23, and the connecting head 322 is located inside the slide rail parts 23.

[0039] Based on the fact that the slide rail part 23 is located above the machine tool bed 1, the slide rail part 23 corresponds to the Y-axis feed guide rail on the machine tool bed 1. The base 31 enters between the beam slide rail parts 23 by pushing the protrusion into the slide rail part 23. At the same time, the cover plate 321 is also inserted between the track rods, and can be connected to the X-axis feed component of the machine tool bed 1.

[0040] It should be noted that the slide rail portion 23 is composed of track rods distributed up and down, and a slideway is formed between the track rods. The base 31 is installed between the track rods by inserting the protrusion into the slideway, and the base 31 is connected to the X-axis feed component of the machine tool bed 1 based on the cover body 32. The cover plate 321 adopts a rubber corrugated plate, and the connecting head 322 connected to the cover plate 321 can adopt a magnet, so that the connecting head 322 is adsorbed on the machine tool bed 1, and the cover plate 321 can be deformed and extended to always cover the top to protect the transmission part.

[0041] Taking into account that the base 31 is connected to the slide rail portion 23 in an inserted manner, a connecting hole is opened on the base 31 of the present embodiment, and a fastener 5 is provided on the base 31 through the connecting hole. The fastener 5, which is preferably a bolt, is threadedly connected to the connecting hole and can extend downward to resist the machine tool bed 1, thereby restricting the base 31 and improving the installation stability of the base 31.

[0042] See also Figure 1-4 The front end sealing member 4 includes an end sealing plate 41 and an insertion rod 42 , the insertion rod 42 is symmetrically arranged on the end sealing plate 41 , a support plate 6 is arranged on the cover plate 21 , and one end of the insertion rod 42 extends between the support plate 6 and the cover plate 21 .

[0043] Based on the fact that the cover plate 21 is installed on the side of the machine tool bed 1 in a hanging manner, this embodiment arranges a support plate 6 to separate the interval formed between the cover plate 21 and the machine tool bed 1, so that the interval between the support plate 6 and the cover plate 21 can correspond to the insertion rod 42 of the front end sealing member 4, and the end sealing plate 41 is fitted to the machine tool bed 1. In this way, the end sealing plate 41 can be removed by simply holding the insertion rod 42 in front of the machine tool bed 1 and applying force.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
