Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] A guiding structure for a numerically controlled lathe includes a guide rail frame 1. A guide block 2 is arranged on the upper side of the guide rail frame 1. A clamping assembly is installed at the upper end of the guide block 2. The clamping assembly can be of the existing type. After clamping and positioning the workpiece through the clamping assembly, the guide block 2 is used to drive the workpiece for guiding transportation so that the numerically controlled lathe can perform subsequent processing on the workpiece.

[0029] The guide rail frame 1 has a bottom plate 11 at its bottom. First threaded holes 12 are evenly opened on both sides of the outer end of the bottom plate 11 respectively, so as to facilitate the installation of the bottom plate 11 on the numerically controlled lathe through bolts and assemble the guiding structure with the lathe.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 5, support plates 3 are respectively fixed on the outer sides of the head and tail ends of the guide rail frame 1. A lead screw 31 is rotatably connected between the two support plates 3. Limiting rods 32 are respectively arranged on both sides of the outer end of the lead screw 31, and both ends of the limiting rods 32 are fixed to the two support plates 3. Among them, the lead screw 31 is in threaded connection with the inside of the guide block 2, and the limiting rods 32 penetrate through the inside of the guide block 2. By limiting the movement of the guide block 2 through the limiting rods 32, the whole guide block 2 can be driven to translate when the lead screw 31 rotates. The lead screw 31 is driven by a forward and reverse motor, and the forward and reverse motor is arranged at the outer end of one support plate 3. The lead screw 31 is connected to the output shaft of the forward and reverse motor, and the specific connection method can adopt the existing technology.

[0031] Support plates 6 are respectively fixed on both sides of the lower end of the guide block 2. A cleaning frame 7 is arranged on the lower side of the support plates 6. The movement of the cleaning frame 7 is driven by the movement of the guide block 2, so that the cleaning frame 7 can clean the chips remaining on the upper surface of the guide rail frame 1 after processing. The cleaning frame 7 includes a docking plate 71, a brush 72 and a scraper 73. The brush 72 and the scraper 73 are fixed to the lower end of the docking plate 71. The brush 72 is located on the side of the lower end of the docking plate 71 away from the guide block 2, and the scraper 73 is located on the side of the lower end of the docking plate 71 close to the guide block 2. So that during the movement of the guide block 2, the chips on the upper surface of the guide rail frame 1 can be first swept by the brush 72, and then the remaining part of the chips can be scraped off by the scraper 73.

[0032] Further, a card slot is opened at the lower end of the support plate 6, so that the docking plate 71 can be clamped with the card slot to assemble the cleaning frame 7 and the support plate 6. At the same time, three second threaded holes 61 are opened at the outer end of the support plate 6, and a third threaded hole 711 adapted to the second threaded hole 61 is opened inside the docking plate 71, so that the docking plate 71 and the support plate 6 can be installed and fixed by bolts. After using for a period of time, both the scraper 73 and the brush 72 may be worn. At this time, after the bolts are taken out from the third threaded hole 711 and the second threaded hole 61, the whole cleaning frame 7 can be slid out from the support plate 6 for replacement.

[0033] In a further embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 , installation grooves 4 are respectively opened on the inner sides of the head and tail ends of the guide rail frame 1. A collection box 5 is arranged inside the installation grooves 4. The chips cleaned and pushed out by the cleaning frame 7 can be collected through the collection box 5, and the collection box 5 can slide inside the installation grooves 4, so that the collection box 5 can be slid out from the installation grooves 4. Docking balls 8 are respectively arranged on both sides of the outer end of the collection box 5, which is convenient for the collection box 5 to be positioned in the installation grooves 4 through the docking balls 8, and prevents the collection box 5 from automatically sliding out of the installation grooves 4 without external force.

[0034] Specifically, limiting sliding holes 51 are respectively formed on both sides of the outer end of the collection box 5. The docking balls 8 are slidably connected in the limiting sliding holes 51, and the docking balls 8 are connected to the inside of the limiting sliding holes 51 through springs. One end of the spring is fixed to the docking ball 8, and the other end of the spring is fixed to the inside of the limiting sliding hole 51. Under the elastic force of the spring, the docking ball 8 can be pushed to slide outwards of the limiting sliding hole 51. Docking grooves 42 corresponding to the docking balls 8 are respectively formed on both sides of the inner wall of the installation groove 4, so that the collection box 5 can be kept in a docking state with the installation groove 4 by the clamping connection between the docking balls 8 and the docking grooves 42, preventing the collection box 5 from sliding out of the installation groove 4.

[0035] Furthermore, a concave surface is formed on one side of the outer end of the collection box 5, and a pulling piece 52 is fixed inside the concave surface, which is convenient for an operator to pull and slide the collection box 5 through the pulling piece 52. At the same time, limiting sliding holes 51 are fixed to the bottom of the collection box 5, and a limiting groove 43 is formed at the bottom of the inner end of the installation groove 4. The length of the limiting groove 43 is adapted to the length of the limiting sliding hole 51, so as to limit the sliding of the limiting sliding hole 51 through the limiting groove 43, preventing the collection box 5 from sliding out of the installation groove 4 after being pushed excessively.

[0036] A guide piece 41 is fixed to the upper end of the inner wall of the installation groove 4 near the guide block 2, which is convenient for guiding the discharge of the debris when the cleaning rack 7 pushes the debris into the collection box 5.

[0037] The collection box 5 can collect the debris cleaned and pushed out by the cleaning rack 7, and the collection box 5 can be slid out of the installation groove 4 to clean the debris collected inside the collection box 5. When the collection box 5 is docked with the installation groove 4, the clamping connection between the docking balls 8 and the docking grooves 42 prevents the collection box 5 from sliding out of the installation groove 4.
