[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0028] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a surround-type tool post for a vertical lathe. The surround-type tool post for this vertical lathe includes a tool post unit 100, the tool post unit 100 includes a tool disc 101, and a tool slot 102 is provided around the tool disc 101. A tool 103 is installed inside the tool slot 102. The drive unit 200 includes a connecting column 201 located at the geometric center of the bottom of the cutter head 101. A driven plate 202 is located at the bottom end of the connecting column 201. A U-shaped groove 203 is circumferentially formed on the driven plate 202. An active plate 204 is provided on the side of the driven plate 202. A cam 205 is located at the geometric center of the top surface of the active plate 204. A cylinder 206 is located on one side of the cam 205. A rotating column 207 is located at the geometric center of the bottom of the active plate 204. The fixing unit 300 includes a rotating sleeve 301 disposed on the outside of the rotating column 207, a fixing plate 302 disposed at the bottom end of the rotating sleeve 301, and a protective shell 303 disposed at the top end of the fixing plate 302.
[0029] In this system, rotating column 207 is fixedly connected to drive disk 204. Drive disk 204 rotates together with rotating column 207. During rotation, cylinder 206 rotates into U-shaped groove 203. The number of U-shaped grooves corresponds to the number of tool slots. Drive disk 204 continues to rotate, and cylinder 206 cooperates with U-shaped groove 203, thereby driving driven wheel to rotate. Driven disk 202 is connected to tool disk 101 as a whole through connecting column 201. Rotation of tool disk 101 allows tool 103 to be switched for use, which is suitable for complex machining needs and saves the trouble of frequently changing different specifications of tool 103. To a certain extent, it helps to improve the machining efficiency of lathe. The tool 103 rotates to a downward vertical position for machining. Protective shell 303 protects drive unit 200 and isolates iron filings and impurities generated during machining from entering, preventing the cooperation and rotation of drive disk 204 and driven disk 202 from being affected. Fixing plate 302 fixes this device to the vertical mounting column of lathe.
[0030] Example 2 Reference Figure 1 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a circular groove 104 is formed at the geometric center of the top of the cutter head 101; a clamping block 105 is fixedly installed inside the cutter position groove 102; the cutter 103 consists of a cutter shank 106 and a blade 107; and the clamping block 105 is installed on one side of the cutter shank 106. A first threaded hole 105a is formed on the clamping block 105; a second threaded hole 102a is formed on the cutter position groove 102 at a position corresponding to the first threaded hole 105a; a first bolt 108 is fitted into the first threaded hole 105a and the second threaded hole 102a. A third threaded hole 107a is formed at the geometric center of the top surface of the blade 107; a fourth threaded hole 106a is formed on the cutter shank 106 at a position corresponding to the third threaded hole 107a; and a second bolt 109 is fitted into the third threaded hole 107a and the fourth threaded hole 106a.
[0031] The circular groove 104 can accommodate tool holders 106 of different lengths installed in the tool position groove 102. At the same time, the length of the tool holder 106 extending during processing can be adjusted. The tool holder 106 is locked by adjusting the first bolt 108 on the clamping block 105, and the blade 107 is fixed on the tool holder 106 by tightening the second bolt 109.
[0032] The remaining structure is the same as that in Example 1.
[0033] Example 3 Reference Figures 3-5This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the U-shaped grooves 203 are connected in pairs by arcs 208, and the arcs 208 fit tightly with the outer circle of the cam 205. A limiting clamp 209 is provided on the outer side of the cylinder 206. Hanging platforms 210 extend outward from both ends of the limiting clamp 209 near the cylinder 206, and a pull rod 211 is provided on the side of the limiting clamp 209 away from the cylinder 206. A rotating seat 212 is provided at the geometric center of the bottom of the rotating column 207. A rotating rod 213 is provided on the outer side of the rotating seat 212, and a bearing 214 is installed on the rotating column 207 at a position corresponding to the rotating sleeve 301.
[0034] When the cutter head 101 changes tools, the cylinder 206 engages with the U-shaped groove 203. The cylinder 206 pushes the driven wheel to rotate through the U-shaped groove 203. The driven wheel has six U-shaped grooves 203, corresponding to the six tools 103 on the cutter head 101. When the cylinder 206 pushes the U-shaped groove 203 to rotate one notch, the tool 103 is switched. When the arc 208 and the outer circle of the cam 205 are tightly fitted, they are locked. Pulling the lever 211 can manipulate the position of the limit clamp 209. The clamp 209 limits the cylinder 206 to ensure the locking state of the cutter head 101 during machining. The connection between the rotating seat 212 and the rotating column 207 allows the worker to change the tool on the cutter head 101 by rotating the rotating rod 213. When the rotating rod 213 rotates to point to the clamp 209, the cylinder 206 just rotates to the position of the clamp 209, which can push the clamp 209 to limit the cylinder 206. The bearing 214 ensures that the rotating column 207 rotates better within the rotating sleeve 301.
[0035] The remaining structure is the same as that in Example 2.
[0036] Example 4 Reference Figure 2 , Figure 5 , Figure 6This is the fourth embodiment of the present invention. This embodiment differs from the third embodiment in that: two limiting holes 304 are provided on the outer side of the protective shell 303, a limiting clip 209 passes through the limiting holes 304, a limiting block 305 is provided on one side of the limiting holes 304, and a limiting groove 306 is provided at the bottom end of the limiting holes 304, through which the limiting clip 209 passes. A protective cover 307 is provided at the top of the protective shell 303, and a first circular hole 307a is provided on the protective cover 307, through which the connecting post 201 passes. A second circular hole 303a is provided at the bottom of the protective shell 303, corresponding to the rotating post 207, and a third circular hole 302a is provided on the fixing plate 302, corresponding to the second circular hole 303a. The bottom of the fixing plate 302 is provided with a fifth threaded hole 302b, and the bottom of the protective shell 303 is provided with a sixth threaded hole 303b corresponding to the fifth threaded hole 302b. The fifth threaded hole 302b and the sixth threaded hole 303b are fitted with bolts 308 and nuts 309. The bottom of the fixing plate 302 is provided with multiple fixing holes 310.
[0037] The distance between the mounting platform 210 and the limiting block 305 is the moving distance of the limiting clamp 209. The limiting block 305 ensures that the limiting clamp 209 moves horizontally and will not tilt. At the same time, it prevents the cylinder 206 from shifting after the limiting position, which would cause the tool 103 to move. The protective cover 307 and the protective shell 303 are connected by welding. The protective shell 303 is fixed to the fixing plate 302 by bolts 308 and nuts 309. The fixing plate 302 can be fixed to the vertical mounting column of the lathe through the fixing hole 310.
[0038] The remaining structure is the same as that in Example 3.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
