Abstract
Description
Technical Field
[0001] The utility model relates to hardware processing equipment, in particular to a turntable for milling equipment processing. Background Art
[0002] Whether in household or industrial pipelines, due to different installation environments, various adapters are often needed to adjust the trend of the pipeline system so that the transmitted medium can reach the destination smoothly. In some complex environments, S-bend connectors are needed to connect one end of the S-bend to the pipeline and the other end of the S-bend to another pipeline, so that two sections of pipelines at different heights can be connected together with only one connector.
[0003] The existing S-bend is loaded through a turntable during processing. In order to ensure the stability of the workpiece, the turntable needs to be fixed by a fixed structure. However, when the structure of the fixed workpiece is pressurized, the turntable is prone to tilt toward the side where the fixed structure is set. Usually, this tilt cannot be seen by the naked eye, and workers cannot judge it. After a period of time, the turntable is obviously prone to tilt toward one side of the workpiece, causing the entire turntable to be unable to accurately move the workpiece to the processing end when rotating. If the workpiece is not stable enough during the continuous feeding stage, it is easy to cause inaccurate milling position, high scrap rate of milling products, and even easy to cause tool collision. Utility Model Content
[0004] The utility model provides a turntable for milling equipment processing, which feeds materials in the form of a turntable, can fix the workpiece during the workpiece processing to avoid turbulence during the milling process, and can also balance the fixed structure of the workpiece to balance the force of the turntable, so that the turntable can always maintain high-precision operation during a long period of work.
[0005] The utility model is achieved in this way:
[0006] A milling equipment processing turntable is arranged on a workbench, comprising:
[0007] A stable turnover processing table, wherein a turnover frame is arranged on the workbench, the stable turnover processing table comprises a turnover plate fixedly connected to the top of the turnover frame, a plurality of fixtures for clamping workpieces are welded on the upper top surface of the turnover plate, a first stabilizing member is arranged at the top of the connection position between the turnover plate and the milling cutter, and a second stabilizing member is arranged at the bottom of the connection position between the turnover plate and the milling cutter;
[0008] When the turnover rack moves the turnover plate to the processing position of the milling cutter, the first stabilizing member presses the workpiece on the tooling while the second stabilizing member presses the lower bottom surface of the turnover plate.
[0009] As a further improvement, the first stabilizing member is used to fix the upper top surface of the workpiece in the tooling, and the first stabilizing member includes a middle pressure block that applies pressure to the recessed position in the middle of the workpiece, and side slideways for sliding installation of side pressure blocks are provided on both sides of the middle pressure block. A push rod motor is connected to the top of the middle pressure block, and the side pressure blocks are pressed against both sides of the top surface of the workpiece when the push rod motor is pushed out for the first time, and the middle pressure block is pressed against the middle position of the top surface of the workpiece when the push rod motor is pushed out for the second time. When the push rod motor is retracted for the first time, the middle pressure block leaves the middle position of the top surface of the workpiece, and when the push rod motor is retracted for the second time, the side pressure blocks leave both sides of the top surface of the workpiece.
[0010] As a further improvement, the second stabilizing member includes a hydraulic push rod locked on the workbench, the hydraulic push rod is located on the side of the turnover frame close to the driving structure, the top of the hydraulic push rod is connected to an articulated seat, the articulated seat is locked to the lower end of a multi-function frame, the hydraulic push rod is electrically connected to the push rod motor, when the push rod motor is pushed out, the hydraulic push rod is synchronously pushed out and presses the multi-function frame against the bottom of the turnover plate.
[0011] As a further improvement, the multifunctional frame is a U-shaped structure, and a fixed frame welded to the workbench is provided at one end of the bottom of the multifunctional frame away from the push rod motor. A debris receiving groove is provided on the top surface of the workbench corresponding to the lower position of the milling cutter, and when the hydraulic push rod is pushed out, the multifunctional frame is tilted to point to the debris receiving groove.
[0012] As a further improvement, the side pressure block includes a first side pressure block and a second side pressure block located on both sides of the middle pressure block, the first side pressure block corresponds to the top surface of the first interface of the workpiece, and the second side pressure block corresponds to the top surface of the second interface of the workpiece.
[0013] The beneficial effects of the utility model are:
[0014] During the workpiece processing of the utility model, in order to avoid the displacement of the workpiece during the milling process so as to affect the milling position and depth, the turnover frame needs to be used in conjunction with the first fixing member. After the workpiece is moved into place by the turnover frame, the first fixing member fixes the top of the workpiece so that the workpiece can still maintain a stable state during the stage of being acted by the milling cutter, thereby ensuring the processing accuracy.
[0015] In the process of using the above-mentioned turnover rack to circulate the workpiece, since the workpiece needs to be transported to the position corresponding to the milling cutter each time, the turnover rack needs to always maintain a high movement accuracy. However, due to the setting of the first stabilizing member, pressure will be provided on the lateral side of the entire turnover rack. In the process of each time the workpiece is pressed down, the turnover rack will tilt in the direction of the setting of the first stabilizing member. Over time, it will affect the rotation accuracy of the turnover rack, causing the workpiece to deviate from its original position, making the workpiece unable to meet the processing standard. In this regard, the present invention further provides a second stabilizing member on the basis of the first stabilizing member. In the process of each time the first stabilizing member presses down the workpiece, the bottom of the turnover plate is balanced by the second stabilizing member, thereby preventing the tilt of the turnover plate from affecting the turnover rack.
[0016] In summary, by setting up a stable turnover processing table, not only can the batch milling of S-elbows be realized to improve the overall processing efficiency, but also the batch processed parts can meet the requirements of industry standards. The hole positions of the elbows are very precise and are not affected by long-term batch production tolerances. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0024] Reference Figure 1 to Figure 4 As shown, a turntable for milling equipment processing is arranged on a workbench 10, including: a stable turnover processing table, a turnover frame 30 is arranged on the workbench 10, the stable turnover processing table includes a turnover plate 41 fixedly connected to the top of the turnover frame 30, a plurality of fixtures 411 for clamping workpieces are welded on the upper top surface of the turnover plate 41, a first stabilizing member 42 is arranged on the top of the connection position between the turnover plate 41 and the milling cutter 221, and a second stabilizing member 43 is arranged on the bottom of the connection position between the turnover plate 41 and the milling cutter 221; when the turnover frame 30 moves the turnover plate 41 to the processing position of the milling cutter 221, the first stabilizing member 42 presses the workpiece on the fixture 411 while the second stabilizing member 43 presses the lower bottom surface of the turnover plate 41.
[0025] In the positioning and fixing stage of the first stabilizing member 42, the first stabilizing member 42 is used to limit and fix the upper top surface of the workpiece on the tooling 411. The first stabilizing member 42 includes a middle pressure block 421 for applying pressure to the concave position in the middle of the workpiece. A push rod motor 424 is connected to the top of the middle pressure block 421. When the push rod motor 424 moves downward, it drives the middle pressure block 421 to press against the top surface of the workpiece. The push rod motor 424 drives the middle pressure block 421 to press down on the platform part of the S-bend workpiece, so that it is fixed in the tooling 411.
[0026] The workpiece in this embodiment is an S-elbow, so the tooling 411 in this embodiment also needs to be configured to adapt to the shape of the S-elbow. The S-elbow in this embodiment has a horizontal platform portion in the middle to facilitate cooperation with the middle pressure block 421, so that the middle pressure block 421 can have a sufficiently stable contact surface when pressed down.
[0027] This embodiment enables all workpieces to be milled accurately and efficiently by adding a stable turnover processing table, as follows:
[0028] In the initial processing stage, the workpieces can be placed one by one on the tooling 411 of the turnover plate 41 by manual loading by workers or loading by a robot, and the turnover plate 41 is driven to work by the turnover frame 30, so that the workpieces are regularly contacted with the milling cutter 221, and the workpieces are processed by milling, without the need for manual continuous loading and unloading, and more finished workpieces can be processed in the device during the cycle of processing a workpiece on the lathe, and the processing efficiency is higher;
[0029] During the workpiece processing, in order to avoid displacement of the workpiece during the milling process, thereby affecting the milling position and depth, the revolving frame 30 needs to be used in conjunction with the first stabilizing member 42. After the workpiece is moved into position by the revolving frame 30, the first stabilizing member 42 is used to fix the top of the workpiece, so that the workpiece can still maintain a stable state when being acted on by the milling cutter 221, thereby ensuring the processing accuracy.
[0030] In the process of using the above-mentioned turnover rack 30 to circulate the workpiece, since the workpiece needs to be transported to the position corresponding to the milling cutter 221 each time, the turnover rack 30 needs to always maintain a high movement accuracy. However, due to the setting of the first stabilizing member 42, pressure will be provided on the lateral side of the entire turnover rack 30. In the process of each time the workpiece is pressed down, the turnover rack 30 will tilt in the direction of the setting of the first stabilizing member 42. Over time, it will affect the rotation accuracy of the turnover rack 30, causing the workpiece to deviate from its original position, making the workpiece unable to meet the processing standard. In this regard, the present invention further provides a second stabilizing member 43 on the basis of the first stabilizing member 42. In the process of each time the first stabilizing member 42 presses down the workpiece, the bottom of the turnover plate 41 is balanced by the second stabilizing member 43, thereby preventing the tilt of the turnover plate 41 from affecting the turnover rack 30.
[0031] In summary, by setting up a stable turnover processing table, not only can the batch milling of S-elbows be realized to improve the overall processing efficiency, but also the batch processed parts can meet the requirements of industry standards. The hole positions of the elbows are very precise and are not affected by long-term batch production tolerances.
[0032] During the positioning and fixing stage of the first stabilizing member 42, the intermediate pressure block 421 is used to apply pressure to the platform portion of the S-bend workpiece, so that it is fixed in the tooling 411. After applying the first stabilizing member 42 structure, the applicant found that if only a simple intermediate pressure block 421 structure is used, there is a certain probability that the workpiece will be pulled upward during the lifting process of the intermediate pressure block 421 to implement the positioning effect, so that the workpiece is out of the original position and may even roll toward the position of the milling cutter 221. In response to this, the applicant changed the originally envisioned intermediate pressure block 421 structure and further added an intermediate pressure block 421 structure to the intermediate pressure block 421 structure. The side pressure blocks of block 421 are arranged laterally to slide up and down. The side pressure blocks are in an active state and can contact the workpiece before the middle pressure block 421 when the push rod motor 424 pushes the middle pressure block 421 out for the first time. In the stage when the middle pressure block 421 retreats, although the middle pressure block 421 leaves the workpiece, the side pressure blocks still do not leave the workpiece. This can prevent the middle pressure block 421 from deviating from the workpiece. Since the side pressure blocks are arranged at both ends and the contact points with the workpiece are small, they will not deviate from the workpiece, so that the first stabilizing member 42 will not interfere with the position of the workpiece when it is separated from the workpiece.
[0033] During the process of the first stabilizing member 42 applying pressure, the turntable 41 will undergo an angle change that is difficult to observe with the naked eye. Although it will not affect the turntable 41 and the turntable frame 30 once or twice, this slight effect will gradually increase during the processing of thousands of workpieces per day, thereby affecting the turnover accuracy of the turntable frame 30, and then making the turntable 41 unable to rotate to the set angle. Therefore, the second stabilizing member 43 and the first stabilizing member 42 are in a synchronously pushed out state, which will synchronously apply balanced pressure to the upper and lower ends of the turntable 41. Therefore, the second stabilizing member 43 in this embodiment includes a hydraulic push rod 431 locked on the workbench 10, and the hydraulic push rod 431 is located on the side of the turntable 30 close to the drive structure 20, and the top of the hydraulic push rod 431 is connected to an articulated seat 432, and the articulated seat 432 is locked in a multi-function frame 433. At the lower end, the hydraulic push rod 431 is electrically connected to the push rod motor 424. When the push rod motor 424 is pushed out, the hydraulic push rod 431 is pushed out synchronously and presses the multi-function frame 433 against the bottom of the turntable 41. The hydraulic push rod 431 in the second stabilizing member 43 must be electrically connected to the push rod motor 424 to allow the two to reach a relatively balanced state. After the first stabilizing member 42 is separated from the workpiece, the multi-function frame 433 driven by the hydraulic push rod 431 also drops accordingly. The width of the multi-function frame 433 can be set to one-eighth or one-twelfth of the arc length of the turntable 41, as long as it can support the processing area corresponding to the first stabilizing member 42. In order to make the cooperation between the hydraulic push rod 431 and the multi-function frame 433 more flexible and avoid the hydraulic push rod 431 from exploding, the hydraulic push rod 431 and the multi-function frame 433 are in a hinged state.
[0034] During actual use, the push rod motor 424 will have two descending processes and two retracting processes. The first descent is when the side pressure block contacts the workpiece first, and the second descent is when the middle pressure block 421 also contacts the workpiece. It should be emphasized that the side pressure block has no external limiting structure and power structure, but only cooperates with the side slide 423 through its own gravity. Therefore, during the retraction of the push rod motor 424, it will only retract the middle pressure block 421 for the first time, and will pull the side pressure block connected to the middle pressure block 421 up for the second time.
[0035] Since the two ends of the workpiece platform have different heights, it cannot be fixed by a side pressure block of uniform height. Therefore, the side pressure block includes a first side pressure block 4221 and a second side pressure block 4222 located on both sides of the middle pressure block 421. The first side pressure block 4221 corresponds to the top surface of the first interface of the workpiece, and the second side pressure block 4222 corresponds to the top surface of the second interface of the workpiece. It should be noted that the contact surface between the first side pressure block 4221 and the second side pressure block 4222 and the workpiece is much smaller than that of the middle pressure block 421, so it is not easy to lift the workpiece when it is separated from the workpiece.
[0036] The multifunctional frame 433 in this embodiment not only serves to balance the first stabilizing member 42, but also when the second stabilizing member 43 is in the process of being lifted, it indicates that the workpiece is being processed by the milling cutter 221, and chips are flying around. The multifunctional frame 433 is a U-shaped structure, and a fixing frame 434 welded to the workbench 10 is provided at one end of the bottom of the multifunctional frame 433 away from the push rod motor 424. A chip receiving groove 11 is provided on the top surface of the workbench 10 corresponding to the lower position of the milling cutter 221. When the hydraulic push rod 431 is pushed out, the multifunctional frame 433 is tilted toward the chip receiving groove 11. The multifunctional frame 433 with a U-shaped opening can receive the waste chips generated during milling and guide them into the chip receiving groove 11. The entire multifunctional frame 433 has the effect of pressing and removing chips, and the fixing frame 434 can have a supporting effect, and also provides a second fulcrum for the multifunctional frame 433.
[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
