Description

Technical Field

[0001] The utility model relates to the technical field of deep hole drilling machines. Background Art

[0002] A guide sleeve seat and a support frame are generally provided in front of the spindle box of a deep hole drilling machine to support the deep hole drilling and milling drill bit and gun rod, so that the drill bit and gun rod can be kept in the same center as the spindle during processing, avoiding excessive deviation of the processed hole. Since the guide sleeve seat and the support frame hinder the forward movement of the spindle box, the spindle box equipped with milling or tapping tools cannot be moved forward to directly perform milling and tapping processing on the workpiece, which limits the use of the machine tool. There is a structure that uses a guide sleeve seat to achieve coordination with the spindle box by the reciprocating motion of a slide rail. The slide rail needs to be set on the front side of the spindle box, and the guide rail has a certain length, so it will occupy more space in front of the spindle box. The workpiece that needs to be rotated and placed will be interfered with by this part of the guide rail when performing oblique hole processing, which limits the rotation and placement angle of such workpieces and reduces the production capacity of the machine tool. Therefore, there is room for improvement in the existing guide sleeve seat moving structure. Utility Model Content

[0029] See attached Figure 1-2 , shown is a platform equipped with a movable guide sleeve seat, the platform having a spindle box 4, a guide sleeve seat 6 and a slide rail seat 3, the slide rail seat 3 is provided with a main slide rail 301, the spindle box 4 and the guide sleeve seat 6 can be installed on the main slide rail 301 for sliding back and forth, and the guide sleeve seat 6 is located in front of the spindle box 4, the platform also has a rotatable carrying platform 5, the carrying platform 5 is provided with a secondary slide rail 500 that fits with the main slide rail 301; the carrying platform 5 rotates to the front end of the slide rail seat 3 so that the secondary slide rail 500 is docked with the main slide rail 301, the guide sleeve seat 6 slides to the secondary slide rail 500, and the carrying platform 5 rotates to one side of the slide rail seat 3 to avoid the spindle box 4 together with the guide sleeve seat 6.

[0030] In the deep hole drilling process, the carrier 5 rotates toward the slide rail seat 3 until the auxiliary slide rail 500 docks with the front end of the main slide rail 301, and the guide sleeve seat 6 slides along the main slide rail 301 to the front of the spindle box 4 to provide support for the drill bit and avoid excessive deviation of the processed hole; when the spindle of the spindle box 4 is equipped with a tool to mill or tap the workpiece, the guide sleeve seat 6 slides onto the auxiliary slide rail 500, and the carrier 5 rotates to the side of the slide rail seat 3. Together with the guide sleeve seat 6, it avoids the spindle box 4, making it easier for the spindle equipped with the tool to process the workpiece. Compared with the previous method of controlling the guide sleeve seat 6 by the slide rail, the use of rotation to achieve the coordination between the guide sleeve seat 6 and the spindle box 4 has a more streamlined structure and occupies less space. It is conducive to making room for more workpiece placement in front of the spindle box 4, reducing interference with the workpiece, and is conducive to processing workpieces of different shapes. The angle at which the workpiece can be placed is also increased, which can improve the processing capacity of the machine tool.

[0031] In some embodiments, the platform includes a column 1 and a slide base 2, the slide base 2 can be installed on the column 1 in a liftable manner, the carrier 5 can be hinged to the front end of the slide base 2 for inward and outward rotation, the slide rail seat 3 is installed on the outside of the slide base 2, the spindle box 4 is installed on the outside of the slide rail seat 3, and the front end of the slide rail seat 3 extends forward to exceed the front end of the slide base 2.

[0032] The column 1 is the supporting structure of the platform and is longitudinally extended. The ram base 2 is mounted on the column 1 so that it can be raised and lowered. The height of the rail seat 3 can be adjusted by raising and lowering the ram base 2, so that the spindle box 4 on the rail seat 3 can be processed at different heights and can be flexibly applied to processing scenarios with different height requirements. The carrier 5 is hinged to the front end of the ram base 2. When it rotates outward, it will reach the front end of the rail seat 3. The auxiliary slide 500 is connected and corresponds to the main slide 301. The guide sleeve seat 6 slides to the front of the spindle box 4 and rotates inward away from the rail seat 3. When it slides to the guide sleeve seat 6 on the auxiliary slide 500, it is taken away. Since the front end of the ram base 2 is further back than the front end of the rail seat 3, when the carrier 5 rotates backward, it will make more space to place the workpiece.

[0033] Specifically, after the carrier platform 5 rotates inward, the front end of the slide rail seat 3 exceeds or is flush with the carrier platform 5. Figure 1-2The carrier platform 5 rotates inward approximately 180 degrees, moving the guide sleeve 6 away. This portion is roughly flush with the front end surface of the slide rail base 3. If the carrier platform 5 rotates inward further, more space will be freed up. Of course, this requires a reasonable design after considering other related structures such as the column 1. It can be seen that by using the rotation of the carrier platform 5 to move the guide sleeve 6 away, more space can be made around the front end of the slide rail base 3. In the past, the track controlled the linear reciprocating motion of the guide sleeve 6. The track was protruding relative to the slide rail base 3, and its existence had to occupy the space on the side in front of the slide rail base 3, which greatly interfered with the placement of the workpiece.

[0034] In some embodiments, the first end 501 of the carrier platform 5 is hinged to the slide base 2 through a longitudinal axis 503, and the second end 502 of the carrier platform 5 opposite to the first end 501 is provided with the secondary slide rail 500; a linear drive component 7 is installed on the slide base 2, and the linear drive component 7 can adopt a hydraulic cylinder, etc. The linear drive component 7 is connected to a linear rack 700 to control its forward and backward movement, and the longitudinal axis 503 is configured with a transmission gear 504, and the transmission gear 504 is engaged with the linear rack 700 to rotate under its control.

[0035] See attached Figure 3 The carrier 5 has two ends: a first end 501 and a second end 502. A longitudinal shaft 503 is fixed to the first end 501. The front end of the ram base 2 is provided with an axial hole, into which the longitudinal shaft 503 is mounted, enabling the rotation of the carrier 5. The rotation of the carrier 5 is controlled by a linear drive 7. The linear drive 7 outputs a linear motion, causing the linear rack 700 to move back and forth. The transmission gear 504, receiving the force from the linear rack 700, rotates, thereby driving the carrier 5 to rotate via the longitudinal shaft 503.

[0036] In some embodiments, the column 1 is equipped with a servo motor, which is transmission-connected to the slide base 2. A first longitudinal slide rail 101 is provided on the outer side of the column 1, and the slide base 2 is installed on the first longitudinal slide rail 101; a second longitudinal slide rail 102 is provided on the front side of the column 1, and the linear drive member 7 is slidably assembled on the second longitudinal slide rail 102.

[0037] There is no limit to the number of tracks on each of the first longitudinal slide 101 and the second longitudinal slide 102. The first longitudinal slide 101 may have two or three tracks, while the second longitudinal slide 102 may have a single track. The servo motor is activated, transmitting power to the ram base 2 via a screw, causing it to rise and fall along the first longitudinal slide 101. The linear drive member 7 then simultaneously rises and falls along the second longitudinal slide 102. The first longitudinal slide 101 is disposed on the outside of the column 1, and the second longitudinal slide 102 is disposed on the front side of the column 1. These two rails are arranged in two perpendicular planes, coordinating the lifting and lowering motion of the ram base 2 while also enhancing the stability of the lifting and lowering motion.

[0038] Furthermore, the first end 501 and the second end 502 of the carrier 5 are connected by a bend, so that when the carrier 5 rotates inward, the second end 502 is positioned further back than the first end 501. The first end 501 of the carrier 5 serves as its support for rotation. When the carrier 5 rotates backward, the second end 502 is relatively farther away from the slide rail base 3 and further back than the first end 501, creating more space and making it easier to adjust and place workpieces.

[0039] In some embodiments, the rail seat 3 is rotatably mounted on the ram base 2. The rail seat 3 can be rotated up and down to be inclined or horizontal so that the spindle box 4 can be used in different processing scenarios.

[0040] See attached Figure 4-6 The rail base 3 is hinged to the ram base 2. A rotary drive motor 302 is provided on the rail base 3, which is equipped with a drive gear. The ram base 2 is equipped with an arcuate rack 200, which meshes with the drive gear. The hinge axis between the rail base 3 and the ram base 2 is placed horizontally and inserted vertically onto the rail base 3 and the ram base 2 in an outward-outward direction, allowing the rail base 3 to rotate up and down along the outer surface of the ram base 2. The power for the rotation of the rail base 3 comes from the rotary drive motor 302, which controls the rotation of the drive gear, thereby driving the gear along the arcuate rack 200, thereby driving the rail base 3.

[0041] Furthermore, the rail seat 3 is provided with a guide seat 303 adapted to the arc-shaped rack 200. The guide seat 303 is arc-shaped and fits the side wall of the arc-shaped rack 200. When the rail seat 3 rotates up and down, the guide seat 303 moves along the arc-shaped rack 200, thereby enhancing the stability of the rail seat 3.

[0042] A deep hole milling and drilling machine is provided, wherein the machine is equipped with a platform as described in any of the preceding items.

[0043] The preferred solution and workflow of the platform and machine tool provided in this application are briefly described as follows: the transverse track on the front side of the slide rail seat 3 is removed, and the guide sleeve seat 6 is retained in front of the spindle box 4 in the deep hole drilling processing scenario, sliding with the spindle box 4 on the main slide rail 301, and a new swing-type carrier platform 5 is added. When the spindle of the spindle box 4 carrying the rotating shaft tool needs to be moved forward to perform milling, tapping, etc. on the workpiece, the guide sleeve seat 6 is moved away from the front of the spindle box 4 according to the following steps:

[0044] Rotate the slide rail seat 3 along the slide ram base 2 to a horizontal state, rotate the carrier platform 5 from the inside to the outside to the front end of the slide rail seat 3, dock the auxiliary slide rail 500 with the main slide rail 301, and send the guide sleeve seat 6 onto the auxiliary slide rail 500 of the carrier platform 5. To prevent the guide sleeve seat 6 from detaching, the guide sleeve seat 6 can be fixed on the carrier platform 5, and then the carrier platform 5 is rotated inward to move it and the guide sleeve seat 6 away from the front end of the spindle box 4. The spindle box 4 moves forward along the main slide rail 301 to the original working position of the guide sleeve seat 6, allowing the spindle equipped with the tool to directly cut the workpiece.

[0045] The longitudinal axis 503 of the carrier 5 is set at the front end of the slide base 2. The front end of the slide base 2 is located at a rearward position compared to the front end of the slide rail seat 3. When the carrier 5 rotates inward and leaves the front end of the slide rail seat 3, the distance between the guide sleeve seat 6 and the front end of the slide rail seat 3 is larger after moving away, and its position is further rearward. The distance that can be achieved by the slide rail guide sleeve portion 8 of the old design is smaller.

[0046] For details, please refer to the attached Figure 7 The old design of the slide rail guide sleeve 8 is protruding on the front side of the slide rail seat 3. After the guide sleeve seat 6 is moved away, it inevitably occupies the space on the side of the slide rail seat 3, which greatly limits the placement angle of the first workpiece 9. The improved carrier platform 5 avoids the occupation of the space on the side of the slide rail seat 3 by the protruding track. From the placement angle of the second workpiece 10, it can be seen that the space vacated there is increased, which is convenient for adjusting the rotation placement angle of the workpiece and improving the processing capacity of the machine tool.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications, combinations, and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be within the scope of the claims of the present invention.
