Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of taper hole machines, specifically to an eight-station high-efficiency rotary taper hole machine. Background Technology

[0002] In the field of machining, tapered hole machining is a key process in parts assembly, and its machining efficiency and accuracy directly affect product performance. For workpieces that require machining multiple tapered holes, traditional machining equipment generally suffers from the technical bottleneck of not being able to complete the machining of multiple tapered holes in one go. This forces the workpiece to be transferred between multiple machines, which not only increases the complexity of the process and the number of clamping operations, but also severely restricts the machining accuracy due to the accumulation of positioning errors, making it difficult to meet the demands of modern production for efficient and precise machining.

[0003] Existing tapered hole machining equipment mostly adopts a single-station or few-station structure, and can only complete the machining of one or a small number of tapered holes per clamping. Taking an eight-hole flange as an example, traditional equipment requires multiple clamping operations, with each clamping taking about 10-15 minutes, and the positioning error of each clamping can reach 0.03-0.05mm. The cumulative error causes the coaxiality of the tapered hole to fail to meet high precision requirements. At the same time, the multi-equipment processing mode extends the production cycle by more than 50%, the equipment occupies a large area, and energy costs remain high. In addition, when dealing with workpieces of different specifications, traditional equipment requires frequent changes of tooling fixtures, with changeover time as long as 1-2 hours, which seriously affects the flexibility of multi-variety, small-batch production.

[0004] With the increasing demand for complex components in aerospace, automotive manufacturing, and other fields, the number and precision requirements of tapered holes on workpieces are rising. For example, the housing of a new energy vehicle motor requires the machining of 12 high-precision tapered holes. Traditional equipment often suffers from drawbacks such as "lack of multi-station machining, significant clamping errors, and low changeover efficiency," leading to delivery delays and increased processing costs by more than 30%. There is an urgent need to develop a new type of tapered hole machining machine with multi-station synchronous machining capabilities to solve the industry problem of "low efficiency and unstable precision in multi-tapered hole machining" and promote the upgrading of machining towards high efficiency and intelligence. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an eight-station high-efficiency rotary taper hole machine, which solves the technical problem that traditional processing equipment generally cannot complete the processing of multiple taper holes at one time for workpieces that need to be processed with multiple taper holes. This results in the workpiece having to be transferred between multiple machines, which not only increases the complexity of the process and the number of clamping times, but also seriously restricts the processing accuracy due to the accumulation of positioning errors.

[0006] According to one aspect, at least one embodiment of this disclosure provides an eight-station high-efficiency rotary taper boring machine, comprising:

[0007] The equipment rack and the central disk, wherein the central disk is disposed within the equipment rack;

[0008] A workpiece conversion assembly is disposed on the equipment frame and the central disk;

[0009] Several rectangular slots and a tapered hole assembly, wherein the rectangular slots are all formed on the surface of the equipment frame, and the tapered hole assembly is disposed in the rectangular slots;

[0010] The top frame and the feeding / discharging assembly are provided, wherein the top frame is fixed to the outside of the equipment frame and the feeding / discharging assembly is mounted on the top frame;

[0011] The workpiece conversion assembly includes a drive motor, which is located at the bottom of the equipment frame. The central disk is rotatably connected to the equipment frame. The output end of the drive motor is connected to the central disk. Several telescopic cylinders are provided at the bottom of the central disk, and the output end of each telescopic cylinder is provided with a fixed base.

[0012] As a further technical solution, a pair of fixing blocks are provided on the surface of the fixing seat, a guide rod is provided inside the fixing seat, a clamping block is slidably connected on the guide rod, and a second cylinder is provided at the bottom of the fixing seat, with the output end of the second cylinder connected to the clamping block.

[0013] As a further technical solution, the tapered hole assembly includes a drive screw, which is rotatably connected in the rectangular groove. The drive screw is rotated by a motor, and a support frame and a sub-frame are slidably connected in several of the rectangular grooves.

[0014] As a further technical solution, a first control cylinder is provided on the top of the upright frame, and the first control cylinder is fixed at a vertical angle. A second control cylinder is provided on the top of the sub-frame, and the second control cylinder is fixed at a vertical angle.

[0015] As a further technical solution, both the output ends of the first control cylinder and the second control cylinder are connected to a conical motor, and the conical motor located at the output end of the second control cylinder is fixed at a horizontal angle.

[0016] As a further technical solution, the feeding and discharging assembly includes a pair of control screws, both of which are rotatably connected inside the top frame. The control screws are rotated by a motor, and a pair of sliding frames are slidably connected inside the top frame.

[0017] As a further technical solution, the sliding frame and the control screw are connected by a threaded connection, a lifting cylinder is installed on the sliding frame, the output end of the lifting cylinder is connected to a mounting plate, and the lifting cylinder is fixed at a vertical angle.

[0018] As a further technical solution, the clamping block is located at the center of the pair of fixed blocks.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the workpiece conversion assembly drives the central disk to rotate intermittently via a drive motor, achieving eight-station rotation. Each rotation precisely switches the workpiece position. The telescopic cylinder can adjust the height of the fixed seat to adapt to workpieces of different sizes. The fixed block and clamping block on the fixed seat form a three-point positioning. The second cylinder drives the clamping block to slide along the guide rod, firmly clamping the workpiece and preventing it from loosening during processing. This assembly does not require manual part replacement, reduces the number of clamping operations and errors, enables continuous processing of multiple workpieces, improves efficiency, and solves the problems of multiple machine turnover and clamping errors in traditional equipment.

[0021] 2. In this disclosure, the drive screw of the tapered hole assembly is controlled by a motor to rotate, driving the upright and sub-upper frame to slide within a rectangular groove, precisely adjusting the machining position. The control cylinders at the top of the upright and sub-upper frame respectively drive the tapered hole motors in the vertical and horizontal directions, enabling the machining of tapered holes at different angles to meet the needs of complex workpieces. Through screw transmission and cylinder control, multi-position and multi-angle tapered hole machining can be achieved without changing equipment. Multiple tapered hole machining can be completed in one clamping, improving accuracy and efficiency, and solving the problems of multi-process machining and low accuracy of traditional equipment.

[0022] 3. In this disclosure, the control screw of the feeding and discharging assembly is driven by a motor to rotate, which drives the sliding frame to move laterally within the top frame. The lifting cylinder drives the mounting plate to move vertically. The mounting plate can be equipped with a mechanical claw, which can automatically load and unload workpieces. When the workpiece is rotated to the discharge position, the sliding frame moves upward, the lifting cylinder descends to grab the workpiece, and then moves it to the designated position for unloading. The loading operation is reversed. This assembly realizes automated loading and unloading of workpieces, reduces manual intervention, and improves production efficiency and safety. When combined with the workpiece conversion assembly, it forms an automated production line and enhances the intelligence level of the equipment. Attached Figure Description

[0036] like Figures 1-5 As shown, it illustrates an eight-station high-efficiency rotary taper boring machine according to an embodiment of the present disclosure, comprising:

[0037] The equipment rack 1 and the central disk 2 are disposed within the equipment rack 1;

[0038] Workpiece conversion assembly 5, which is disposed on the equipment frame 1 and the central disk 2;

[0039] A plurality of rectangular slots 3 and a conical hole assembly 6, wherein the rectangular slots 3 are all formed on the surface of the equipment frame 1, and the conical hole assembly 6 is disposed in the rectangular slots 3;

[0040] The top frame 4 and the feeding / discharging assembly 7 are provided on the top frame 4.

[0041] The workpiece conversion assembly 5 includes a drive motor 5-1, which is located at the bottom of the equipment frame 1. The central disk 2 is rotatably connected to the equipment frame 1. The output end of the drive motor 5-1 is connected to the central disk 2. Several telescopic cylinders 5-2 are provided at the bottom of the central disk 2. A fixed seat 5-3 is provided at the output end of each telescopic cylinder 5-2. A pair of fixed blocks 5-4 are provided on the surface of the fixed seat 5-3. A guide rod 5-5 is provided inside the fixed seat 5-3. A clamping block 5-6 is slidably connected to the guide rod 5-5. A second cylinder 5-7 is provided at the bottom of the fixed seat 5-3. The output end of the second cylinder 5-7 is connected to the clamping block 5-6.

[0042] In some examples, a workpiece conversion assembly 5 is designed to enable the rotational processing of multiple workpieces. This assembly uses a drive motor 5-1 at the bottom of the equipment frame 1 as its power source. The output of the drive motor 5-1 is connected to the central disk 2, causing the central disk 2 to rotate intermittently on the equipment frame 1, rotating 45° each time, thus achieving eight-station switching. Several telescopic cylinders 5-2 at the bottom of the central disk 2 can be independently controlled. Their output fixed seats 5-3 drive clamping blocks 5-6 to slide along guide rods 5-5 via second cylinders 5-7, achieving workpiece clamping and release. When the workpiece at one station is finished, the drive motor 5-1 rotates the central disk 2, moving the next workpiece to the processing position, while the already processed workpiece moves to the unloading position. Through the intermittent rotation of the drive motor 5-1, the lifting and lowering adjustment of the telescopic cylinders 5-2, and the clamping action of the clamping blocks 5-6, the workpiece conversion assembly 5 achieves efficient rotation of multiple workpieces, improving processing efficiency.

[0043] like Figures 1-5 As shown in the figure, the conical hole assembly 6 in this embodiment includes a drive screw 6-1, which is rotatably connected in the rectangular groove 3. The drive screw 6-1 is rotated by a motor. A support frame 6-2 and a sub-frame 6-3 are slidably connected in several rectangular grooves 3 respectively. A first control cylinder 6-4 is provided on the top of the support frame 6-2, and the first control cylinder 6-4 is fixed at a vertical angle. A second control cylinder 6-5 is provided on the top of the sub-frame 6-3, and the second control cylinder 6-5 is fixed at a vertical angle. A conical hole motor 6-6 is connected to the output end of both the first control cylinder 6-4 and the second control cylinder 6-5. The conical hole motor 6-6 located at the output end of the second control cylinder 6-5 is fixed at a horizontal angle.

[0044] In some examples, a tapered hole assembly 6 is designed to perform tapered hole machining at multiple different positions. This assembly uses a drive screw 6-1 within a rectangular groove 3 as its transmission core. A motor drives the screw 6-1 to rotate, causing the upright frame 6-2 and the sub-frame 6-3 to slide along the rectangular groove 3, adjusting the machining position. The first control cylinder 6-4 at the top of the upright frame 6-2 is vertically fixed, and its output tapered hole motor 6-6 enables vertical tapered hole machining. The second control cylinder 6-5 at the top of the sub-frame 6-3 is also vertically fixed, but its output tapered hole motor 6-6 is fixed at a horizontal angle, enabling horizontal tapered hole machining. Through the independent movement of the upright frame 6-2 and the sub-frame 6-3, the extension and retraction adjustment of the first control cylinder 6-4 and the second control cylinder 6-5, and the different angle settings of the tapered hole motor 6-6, the tapered hole assembly 6 can perform tapered hole machining at multiple positions on the workpiece, meeting the machining requirements of complex workpieces.

[0045] like Figures 1-5 As shown in the figure, the feeding and discharging assembly 7 in this embodiment includes a pair of control screws 7-1, both of which are rotatably connected to the top frame 4. The control screws 7-1 are rotated by a motor. A pair of sliding frames 7-2 are slidably connected inside the top frame 4. The sliding frames 7-2 are connected to the control screws 7-1 by a threaded connection. A lifting cylinder 7-3 is installed on the sliding frame 7-2. The output end of the lifting cylinder 7-3 is connected to a mounting plate 7-4. The lifting cylinder 7-3 is fixed at a vertical angle.

[0046] In some examples, a feeding / discharging assembly 7 is designed to achieve workpiece loading and unloading. This assembly uses a control screw 7-1 within the top frame 4 as a transmission component. A motor drives the screw to rotate, causing the sliding frame 7-2 to slide along the top frame 4, achieving lateral position adjustment. A lifting cylinder 7-3 on the sliding frame 7-2 is vertically fixed, and a mechanical gripper can be mounted on its output end mounting plate 7-4. The vertical movement of the mechanical gripper is achieved through the extension and retraction of the lifting cylinder 7-3. When the workpiece rotates to the unloading position, the control screw 7-1 drives the sliding frame 7-2 to move above the workpiece, the lifting cylinder 7-3 descends to allow the mechanical gripper to grasp the workpiece, and then rises and moves to the designated position for unloading. During loading, the operation is reversed, placing the workpiece to be processed on the fixed seat 5-3 of the central plate 2. By controlling the lateral movement of the screw 7-1, the vertical movement of the lifting cylinder 7-3, and the loading and unloading actions of the mechanical gripper, the feeding / discharging assembly 7 achieves automated workpiece loading and unloading, reducing manual intervention and improving production efficiency.

[0047] For example, such as Figure 1 As shown, the clamping block 5-6 is located at the center of the pair of fixing blocks 5-4.

[0048] In some examples, by placing the fixing block 5-4 at the midpoint of the interval between the clamping blocks 5-6, a three-point positioning fixation can be formed, which makes the workpiece clamped and fixed more firmly and will not loosen during processing.

[0049] In actual use: the equipment frame 1 is fixed, the central plate 2 is installed inside the equipment frame 1 via a drive motor 5-1, the telescopic cylinder 5-2 is fixed to the bottom of the central plate 2 and its output end is connected to the fixed seat 5-3, the fixed seat 5-3 has a fixing block 5-4 on its surface, and a guide rod 5-5 and a second cylinder 5-7 are provided inside, the output end of the second cylinder 5-7 is connected to a clamping block 5-6, the rectangular groove 3 is opened on the surface of the equipment frame 1, the drive screw 6-1 of the conical hole assembly 6 is installed in the rectangular groove 3, the upright frame 6-2 and the sub-frame 6-3 are slidably connected in the rectangular groove 3, the top is provided with a control cylinder and a conical hole motor 6-6, and the top frame 4 is fixed to the outside of the equipment frame 1 for feeding and discharging materials. The control screw 7-1 of component 7 is installed inside the top frame 4. The sliding frame 7-2 is threadedly engaged with the control screw 7-1. The sliding frame 7-2 is equipped with a lifting cylinder 7-3 and a mounting plate 7-4. In use, the drive motor 5-1 drives the center plate 2 to rotate to the feeding position. The feeding and discharging component 7 clamps the workpiece. The telescopic cylinder 5-2 raises the fixed seat 5-3. The second cylinder 5-7 drives the clamping block 5-6 to clamp the workpiece. The center plate 2 rotates to the processing position. The drive screw 6-1 of the tapered hole component 6 adjusts the position of the upright frame 6-2 and the sub-frame 6-3. The control cylinder drives the tapered hole motor 6-6 to process the tapered hole. After processing, the center plate 2 rotates to the discharge position, and the feeding and discharging component 7 unloads the material.
