Description

Technical Field

[0001] The invention 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 main spindle box of a deep hole drilling machine to support the drill bit and gun rod of the deep hole drilling and milling machine, so that the drill bit and the gun rod can be kept in the same center as the main spindle during the processing, avoiding excessive deviation of the processed hole. Since the guide sleeve seat and the support frame hinder the forward movement of the main spindle box, the main spindle box equipped with milling or tapping tools cannot move 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 main spindle box by the reciprocating motion of a slide rail. The slide rail needs to be set on the front side of the main spindle box, and the guide rail has a certain length, so it will occupy more space in front of the main spindle box. The workpiece that needs to be rotated and placed will be interfered by this part of the guide rail when the inclined hole is processed, 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. Summary of the invention

[0026] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0029] See attached Figure 1-2 , shown is a platform equipped with a movable guide sleeve seat, the platform has 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 slidably installed on the main slide rail 301, and the guide sleeve seat 6 is located in front of the spindle box 4, the platform also has a rotatable carrier 5, the carrier 5 is provided with a secondary slide rail 500 that matches the main slide rail 301; the carrier 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 carrier 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 processing scenario, the carrier 5 rotates toward the slide rail seat 3 until the auxiliary slide rail 500 is connected to 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 to 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 to the auxiliary slide rail 500, and the carrier 5 rotates to one side of the slide rail seat 3, and it and the guide sleeve seat 6 avoid the spindle box 4 together, so that the spindle equipped with the tool can process the workpiece. Compared with the previous method of controlling the guide sleeve seat 6 by the slide rail, the coordination between the guide sleeve seat 6 and the spindle box 4 is realized by rotation, and its structure is more streamlined and occupies less space, which 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 allowed for the placement of the workpiece 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 is installed on the column 1 in a liftable manner, the carrier 5 is hinged to the front end of the slide base 2 and can rotate inward and outward, the slide rail seat 3 is installed on the outer side of the slide base 2, the spindle box 4 is installed on the outer side 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, which is longitudinally extended. The ram base 2 can be installed on the column 1 in a lifting manner. The height of the slide rail seat 3 can be adjusted by lifting the ram base 2, so that the spindle box 4 on the slide 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 at the front end of the ram base 2. It will reach the front end of the slide rail seat 3 when it rotates outward. The auxiliary slide rail 500 is connected and corresponds to the main slide rail 301. The guide sleeve seat 6 slides to the front of the spindle box 4, and it rotates inward away from the slide rail seat 3. The guide sleeve seat 6 on the auxiliary slide rail 500 is taken away. Since the front end of the ram base 2 is located further back than the front end of the slide rail seat 3, when the carrier 5 rotates backward, more space will be made 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 1-2, the carrier 5 rotates inwardly by about 180 degrees, taking the guide sleeve seat 6 away, and this part is roughly flush with the front end surface of the slide rail seat 3. If the carrier 5 rotates inwardly by more, more space will be freed up. Of course, this needs to be reasonably designed after considering other related structures such as the column 1. It can be seen that by using the rotation of the carrier 5 to take away the guide sleeve seat 6, more space can be made around the front end of the slide rail seat 3. In the past, the track controlled the linear reciprocating motion of the guide sleeve seat 6, and the track was protruding relative to the slide rail seat 3. Its existence must occupy the space on the front side of the slide rail seat 3, causing great interference 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, namely a first end 501 and a second end 502. A longitudinal axis 503 is fixed to the first end 501. A shaft hole is provided at the front end of the ram base 2. The longitudinal axis 503 is installed in the shaft hole to realize the rotation function of the carrier 5. The rotation of the carrier 5 is controlled by the linear drive member 7. The linear drive member 7 outputs a linear motion, so that the linear rack 700 moves forward and backward. After receiving the force of the linear rack 700, the transmission gear 504 rotates, thereby driving the carrier 5 to rotate via the longitudinal axis 503.

[0036] In some embodiments, the column 1 is installed with a servo motor, and the servo motor 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 of the first longitudinal slide rail 101 and the second longitudinal slide rail 102. The number of tracks of the first longitudinal slide rail 101 varies from two to three, while the number of tracks of the second longitudinal slide rail 102 can be a single track. The servo motor is started, and the power is transmitted to the ram base 2 through the screw to make it rise and fall along the first longitudinal slide rail 101, and the linear drive member 7 is synchronously raised and lowered along the second longitudinal slide rail 102. The first longitudinal slide rail 101 is arranged on the outside of the column 1, and the second longitudinal slide rail 102 is arranged on the front side of the column 1. The two are arranged in two vertical planes, and while cooperating with the lifting and lowering movement of the ram base 2, the stability of its lifting and lowering movement can also be enhanced.

[0038] Furthermore, the first end 501 of the carrier 5 is bent and connected to the second end 502, so that after the carrier 5 rotates inward, the second end 502 is further back than the first end 501. The first end 501 of the carrier 5 is the support position for its rotation. When it rotates backward, the second end 502 is relatively farther from the slide rail seat 3 and further back than the first end 501, leaving more space, which is more conducive to adjusting and placing the workpiece.

[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 slide rail seat 3 is hinged with the ram base 2, and a rotary drive motor 302 is provided on the slide rail seat 3, and the rotary drive motor 302 is provided with a drive gear. The ram base 2 is provided with an arc-shaped rack 200, and the arc-shaped rack 200 is meshed with the drive gear. The hinge axis of the slide rail seat 3 and the ram base 2 is placed horizontally, and is vertically inserted on the slide rail seat 3 and the ram base 2 in an inward and outward direction, so that the slide rail seat 3 can be attached to the outer surface of the ram base 2 and rotate up and down. The power for the rotation of the slide rail seat 3 comes from the rotary drive motor 302, which controls the rotation of the drive gear, thereby driving the gear along the arc-shaped rack 200, thereby driving the slide rail seat 3.

[0041] Further, the slide 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 slide rail seat 3 rotates up and down, the guide seat 303 moves in contact with the arc-shaped rack 200, thereby enhancing the stability of the slide rail seat 3.

[0042] A deep hole milling and drilling machine tool is provided, wherein the machine tool 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 by the present application are briefly described as follows: the transverse track on the front end 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, and slides with the spindle box 4 on the main slide rail 301, and a swing-type carrier 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 and other processing 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 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 5. To prevent the guide sleeve seat 6 from detaching, the guide sleeve seat 6 can be fixed on the carrier 5, and then the carrier 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, so that the spindle equipped with the tool can directly cut the workpiece.

[0045] The longitudinal axis 503 of the carrier 5 is arranged at the front end of the slide base 2, and 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 it moves away, and its position is further rearward, while 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 slide rail guide sleeve 8 of the old design is protruding on one side of the front end of the slide rail seat 3. After the guide sleeve seat 6 is moved away, it inevitably occupies the space on one side of the slide rail seat 3, which greatly limits the placement angle of the first workpiece 9. The improved carrier 5 avoids the occupation of the space on one 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 vacated space at this place 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 only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications, combinations and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
