Description

Technical Field

[0001] The utility model relates to the technical field of roller press main shaft processing, in particular to a roller press sleeve alloy piece processing equipment. Background Art

[0002] The alloy parts used in the roller press include the roller press main shaft, which is the key component responsible for driving and supporting the rollers in the roller press. The main shaft is usually made of high-strength alloy steel material and has sufficient strength and rigidity to withstand the rotating torque of the roller and the pressure of the material; the roller press main shaft is generally cylindrical and has two ends, one connected to the transmission device for providing power, and the other end is used to connect with the roller. When processing the roller press main shaft, corresponding auxiliary equipment is required. China has authorized a utility model patent (Announcement No.: CN220560974U) to disclose a roller press main shaft production and processing device. Driven by a first motor, two unloading brackets rotate to form a V-shaped angle, and cooperate with the lifting member and the rotating member to fit the bottom of the main shaft on the two unloading brackets to complete the auxiliary processing of the main shaft. Through the precise control of the first motor, the two unloading brackets can form different angles. When facing different sizes of the main shaft, it can be flexibly adjusted to enable it to clamp the main shaft steadily.

[0003] However, there are still some shortcomings in the use of the above device: the spindle limit mainly depends on the self-locking function of the motor, long-term operation is likely to cause wear of the motor, shorten the service life of the motor, and prone to unstable support. At the same time, the support of the spindle mainly depends on the clamping force of the two discharge brackets at a V-shaped angle. This support method is prone to unstable support when processing a heavy spindle, affecting processing accuracy and safety. In summary, the existing device is prone to unstable support during use as the mass of the supported object is different. Therefore, in view of the above problems, a roller press alloy parts processing equipment is proposed. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that when in use, unstable support may occur due to different masses of supported objects, and proposes a roller press sleeve alloy parts processing equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The invention discloses alloy parts processing equipment for roller press, comprising a rotary worktable on which a pair of material discharging brackets are rotatably mounted.

[0007] The surface of the material discharging bracket is provided with a support pad, which includes a triangular column and a trapezoidal column.

[0008] The rotary worktable has an inner cavity, and a driving motor is arranged on the outside of the rotary worktable. The output shaft of the driving motor penetrates into the inner cavity and is connected with a bidirectional screw. One end of the bidirectional screw away from the driving motor is rotatably connected to the inner wall of the inner cavity. The outer wall of the bidirectional screw is symmetrically threaded with a driving block. A pair of driving blocks are rotatably connected with a main support rod, and one end of the main support rod away from the driving block is rotatably connected to the bottom of the discharge bracket.

[0009] Preferably, a groove is provided on the surface of the discharge bracket, and two rows of springs are arranged in the groove, and the tops of the two rows of springs are fixedly connected to the trapezoidal columns.

[0010] Preferably, two guide rods are provided inside the inner cavity, and two sliding blocks are sleeved on the outer walls of the two guide rods. The sliding blocks are provided with sliding holes, and the sliding holes are clearance-matched with the guide rods. Both sliding blocks are rotatably connected to auxiliary support rods, and the ends of the two auxiliary support rods away from the sliding blocks are rotatably connected to the bottom of the main support rod.

[0011] Preferably, one end of the sliding block is fixedly connected to a connecting rod, and one end of the connecting rod away from the sliding block is fixed to one side of the driving block.

[0012] Preferably, the bottom surface of the inner wall of the inner cavity has three sliding grooves, and the bottoms of the driving block and the sliding block are both slidably fitted in the sliding grooves.

[0013] Preferably, a through hole is formed through the outer wall of the rotary worktable, and the through hole cooperates with the output shaft of the driving motor.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model effectively reinforces the bottom of the discharge bracket through the structural design of the driving motor, the bidirectional screw, the main support rod, the guide rod and the connecting rod. When facing a heavy spindle, it can provide more stable and reliable support, which not only improves the safety during the processing, but also because the auxiliary support structure shares part of the spindle weight, reduces the load on the motor when rotating the discharge bracket through the rotating shaft, thereby greatly reducing the working intensity and wear of the motor and extending the service life of the motor.

[0016] 2. The utility model adopts the structural design of the spring, the flat part, the trapezoidal column and the bending part. After a pair of discharge brackets support the main shaft, the trapezoidal column can further fit the outer wall of the main shaft, thereby increasing the contact area between the main shaft and the discharge bracket, making the support of the main shaft more stable.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A roller press alloy parts processing equipment comprises a rotary table 1 on which a pair of material discharging brackets 2 are rotatably mounted.

[0025] A support pad 11 is disposed on the surface of the unloading bracket 2 , and the support pad 11 includes a triangular column 1101 and a trapezoidal column 1102 .

[0026] The rotating worktable 1 has an inner cavity 101, and a driving motor 3 is arranged on the outside of the rotating worktable 1. The output shaft of the driving motor 3 penetrates into the inner cavity 101 and is connected to a bidirectional screw 4. The end of the bidirectional screw 4 away from the driving motor 3 is rotatably connected to the inner wall of the inner cavity 101. The outer wall of the bidirectional screw 4 is symmetrically threaded with a driving block 5. The driving block 5 is slidably matched with the bottom surface of the inner cavity 101. A pair of driving blocks 5 are rotatably connected to a main support rod 6, and the end of the main support rod 6 away from the driving block 5 is rotatably connected to the bottom of the discharge bracket 2.

[0027] In the present embodiment, when in use, the rotating shaft is first driven by the motor to rotate, so that a pair of discharge brackets 2 rotate in a "V" shape, and while the motor is working, the drive motor 3 works synchronously, and the drive motor 3 drives the bidirectional screw 4 to rotate, and the rotation of the bidirectional screw 4 causes a pair of drive blocks 5 to move closer, and then with the flipping of the discharge bracket 2, the main support rod 6 can support the bottom of the discharge bracket 2, and then the main shaft is placed in the "V"-shaped area formed after the pair of discharge brackets 2 are rotated. At this time, the outer wall of the main shaft will contact the surface of the discharge bracket 2, and at the same time, the outer wall of the main shaft close to the bottom of the "V"-shaped area will contact the trapezoidal column 1102, and squeeze the trapezoidal column 1102 at the same time. After the trapezoidal column 1102 is deformed, it will squeeze the spring 202, so that the trapezoidal column 1102 is always in contact with the outer wall of the main shaft.

[0028] In the above implementation:

[0029] The pair of driving blocks 5 are in a rectangular block structure. The pair of driving blocks 5 are provided with threaded holes with opposite thread directions for threading with the bidirectional screw rod 4 .

[0034] In this embodiment, Figure 1 and Figure 2 As shown, a groove 201 is provided on the surface of the discharge bracket 2 , and two rows of springs 202 are arranged in the groove 201 . The tops of the two rows of springs 202 are fixedly connected to the trapezoidal columns 1102 .

[0035] In this embodiment, two rows of springs 202 are provided to connect with the trapezoidal column 1102, so as to support the trapezoidal column 1102, enhance the bending ability of the trapezoidal column 1102, and ensure constant contact with main shafts of different sizes.

[0036] In this embodiment, Figure 3 and Figure 5 As shown, two guide rods 7 are arranged inside the inner cavity 101, and two sliding blocks 8 are sleeved on the outer walls of the two guide rods 7.

The two sliding blocks 8 are rotatably connected to auxiliary support rods 9, and the ends of the two auxiliary support rods 9 away from the sliding blocks 8 are rotatably connected to the bottom of the main support rod 6.

[0037] In this embodiment, by providing the guide rod 7, the sliding block 8 and the auxiliary support rod 9, the supporting capacity of the material discharging bracket 2 can be further improved, thereby ensuring the clamping effect of the material discharging bracket 2.

[0038] In the above embodiment, the connection method of the two ends of the two auxiliary support rods 9 is the same as the connection method of the main support rod 6.

[0039] In this embodiment, Figure 3 and Figure 5 One end of the sliding block 8 is fixedly connected to a connecting rod 10 , and one end of the connecting rod 10 away from the sliding block 8 is fixed to one side of the driving block 5 .

[0040] In this embodiment, the connection rod 10 is arranged so that the sliding block 8 can move along with the movement of the driving block 5 .

[0041] In this embodiment, Figure 3 and Figure 5 As shown, the bottom surface of the inner wall of the inner cavity 101 has three sliding grooves, and the bottoms of the driving block 5 and the sliding block 8 are both slidably fitted in the sliding grooves.

[0042] In this embodiment, the setting of the slide groove ensures that the driving block 5 and the sliding block 8 can slide and provide support thereto.

[0043] In this embodiment, Figure 1 and Figure 3 As shown, a through hole is formed through the outer wall of the rotary table 1 , and the through hole cooperates with the output shaft of the driving motor 3 .

[0044] In this embodiment, the through hole serves as a passage for the output shaft of the driving motor 3 to work, and the inner wall of the rotary table 1 also has a circular hole for cooperating with the bidirectional screw 4 to rotate.
