Description

Technical Field

[0001] This utility model belongs to the field of valve stem processing, specifically, it relates to a valve stem blank cutting device. Background Technology

[0002] In the process of forming valve stems, processes such as cutting and forging are required. Forging results in valve stem blanks of varying lengths, making them unusable directly. They need to be processed. Existing processing equipment cannot guarantee uniform length of the valve stem blanks when cutting them directly. Furthermore, the waste and debris after cutting are not classified and disposed of in a unified manner, falling directly to the ground or remaining at the cutting site. Personnel need to be assigned to clean up the equipment and workshop. Summary of the Invention

[0003] A valve stem blank cutting device includes a detection part, a cutting part, and a collection device;

[0004] The detection section includes a first cylinder, a detection channel, and a laser measuring device. The first cylinder is located at one end of the detection channel and is used to push the valve blank material along the channel. The detection channel has strip-shaped holes that penetrate the side walls on both sides. The laser emitted by the laser measuring device passes through at least one of the strip-shaped holes.

[0005] The cutting part includes a cutting motor, a cutting blade, a clamping lever, and a clamping seat; the cutting blade is mounted on the cutting motor, the clamping seat is located in front of the cutting blade, and the clamping lever cooperates with the clamping seat to achieve clamping;

[0006] The collection device includes a collection bin and a waste collector. The collection bin is located at the other end of the detection channel and is used to collect defective valve stem blanks. The waste collector is located below the cutting blade and is divided into an upper collector and a lower collector. The upper collector is used to collect lumpy debris, and the lower collector is used to collect metal powder.

[0007] Furthermore, the detection section is also provided with a positioning seat, which is located at the end away from the first cylinder and is used to limit the valve stem blank to be detected; the cutting section is provided with a cutting limiting block, which is located in front of the clamping seat and has an opening on the side near the clamping seat. The width of the opening is smaller than the width of the end of the valve stem blank and is used to limit the valve stem blank to be cut.

[0008] Furthermore, the upper end of the positioning seat is provided with wedge-shaped surfaces on both sides, and the wedge-shaped surfaces are arranged opposite to each other.

[0009] Furthermore, the cutting section is also provided with a second cylinder, which is located in front of the cutting limiting block. The second cylinder pushes the valve blank to be limited on the cutting limiting block.

[0010] Furthermore, the clamping lever is clamped in the middle of the clamping seat. The clamping seat has a mounting post on one side, and the upper end of the mounting post has a vertically elongated hole. The clamping lever has a pin, and the pin of the clamping lever is hinged in the elongated hole of the mounting post. The mounting post has a circular hole below the elongated hole, which is fixedly connected to the clamping seat. The end of the clamping seat away from the mounting post has a placement opening. The bottom surface of the placement opening is an arc-shaped surface, and the upper two sides of the placement opening are arc-shaped surfaces.

[0011] Furthermore, a placement groove is provided at the corresponding position of the clamping lever and the clamping seat placement opening. The bottom surface of the placement groove is flat and flush with the lowest surface of the placement opening. The side wall of the placement groove away from the mounting column is higher than the side wall near the mounting column, and both ends have arc-shaped surfaces.

[0012] Furthermore, the length of the opening of the clamping lever placement groove is greater than the length of the opening of the clamping seat placement port; the side wall of the placement groove away from the mounting column is provided with a groove in the direction away from the mounting column.

[0013] Furthermore, the mounting post is fixed to the adjusting cylinder, and the extension and retraction of the adjusting cylinder are used to adjust the angle between the mounting post and the horizontal plane.

[0014] Furthermore, it also includes a position moving part, which includes a vertical moving part and a horizontal moving part;

[0015] The vertical moving part includes a first servo motor, a first driving wheel, a first driven wheel, and a first lead screw. The first servo motor drives the first driven wheel through the first driving wheel, which in turn drives the first lead screw to move the cutting motor along the guide rail in the vertical direction.

[0016] The horizontal moving part includes a second servo motor, a second driving wheel, a second driven wheel, and a second lead screw. The second servo motor drives the second driven wheel through the second driving wheel, which in turn drives the second lead screw to move the cutting motor along the guide rail in the horizontal direction.

[0017] Furthermore, the upper collector and the lower collector are separated by a separation net.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] 1. By cooperating with the cutting components, inspection components, position moving components, and collection devices, the valve stem blank cutting device is made multifunctional, not limited to cutting. After inspection, the workpiece can be directly gripped to the cutting part by the robot. This design integrates the various units, saves space, and makes the work rhythm compact, convenient and flexible.

[0020] 2. The length of the valve stem blank is screened by a laser measuring device. The position of the laser measuring device determines the shortest length of the valve stem blank, and the detection channel detects the longest length of the valve stem blank. The combination of the two ensures the uniformity of the length of the initially selected valve stem blanks. A collection bin is set on one side of the positioning seat of the detection channel, and a wedge-shaped surface is set on the upper side of the positioning seat. Unqualified products are directly grabbed and placed in the collection bin, which is efficient and convenient.

[0021] 3. By setting a waste collector at the bottom of the cutting blade, the cut debris can be collected. The waste collector is set to be divided into upper and lower layers by a separating mesh to classify debris of different sizes, which facilitates the subsequent centralized processing of different types of debris.

[0022] 4. The valve stem blank is fixed during cutting by the interaction of the clamping lever, clamping seat and mounting column. The clamping lever is placed in a slot and the clamping seat is placed in a slot that is offset from each other. The clamping lever moves relative to the valve stem blank when it is placed and removed. This makes it easy and flexible to place and remove the valve stem blank without the need for other clamping mechanisms.

[0023] 5. The two side walls of the clamping lever placement groove are set at different heights. A groove is provided on the higher side wall away from the placement groove. This groove is used to fix the valve stem blank when it is placed. The lower side wall is flat and the upper end is set as an arc surface, which makes it easier to reduce the difficulty when removing the valve stem blank and can be removed quickly.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] The present invention provides a valve stem blank cutting device, the specific implementation of which is as follows:

[0039] like Figures 1-2 As shown, a valve stem blank cutting device includes a detection section, a cutting section, a position moving section, and a collecting device. The collecting device includes a collecting bin 8 and a waste collector 9. The detection section includes a first cylinder 1, a detection channel 2, and a laser measuring device 3. The first cylinder 1 is fixed to a base via a support seat, and the base is fixed to one end of the detection channel 2. Strip-shaped holes 21 are opened along the length direction on both side walls of the detection channel 2 for transmitting laser light to detect the length of the material block. The position of the laser measuring device 3 determines the shortest length of the valve stem blank, ensuring that the length of the initially selected valve stem blank meets the usage requirements. That is, after the laser measuring device 3 is installed and fixed, the shortest length of the valve stem blank to be detected by the detection section can be determined. The length of the detection channel 2 is the longest length of the valve stem blank. The combination of the two can determine the length range of the valve stem blank to be processed, thus satisfying the uniformity of the length of the valve stem blank to be processed. After being placed in the detection channel 2, when the laser emitted by the laser measuring device 3 passes through one strip hole 21 but not the other strip hole 21, it indicates that the length of the valve stem blank detected at this time meets the requirements; when the laser emitted by the laser measuring device 3 passes through the first strip hole 21 and then the second strip hole 21, it indicates that the length of the valve stem blank detected here is unqualified; a valve stem blank positioning seat 10 is provided at the end of the detection channel 2 away from the first cylinder 1, which is used to abut and fix the blank during detection; a collection bin 8 is provided on the back side of the positioning seat 10, and the opening of the collection bin 8 faces the positioning seat 10, which is convenient for collecting valve stem cutting length unqualified products; wedge surfaces 101 are provided on both sides of the upper end of the positioning seat 10, and the wedge surfaces 101 are set opposite each other, which is convenient for removing the abutting end of the blank after the detection is completed. In addition, for blanks with unqualified length, the included angle formed between the two wedge surfaces 101 is used to guide and position the blank, which can be accurately put into the collection bin 8.

[0040] The cutting section includes a cutting blade 5, a cutting limit block 12, a clamping lever 6, a clamping seat 7, a second cylinder 11, a cutting motor 4, a cutting drive wheel, a cutting driven wheel, and a main shaft. Valve nozzle blanks that have passed inspection are transferred to the cutting blade 5. The cutting limit block 12 is positioned on a support platform near the cutting blade 5, and the support platform has an opening. One end of the valve nozzle blank is placed on the opening of the support platform, and the other end is placed on the placement opening 71 of the clamping seat 7. The position of the valve nozzle blank is adjusted by extending and retracting the telescopic rod of the second cylinder 11. Then, it is clamped by the clamping lever 6. Subsequently, the cutting motor 4 drives the cutting drive wheel, which in turn drives the cutting driven wheel via a belt (not shown in the figure), driving the main shaft and ultimately rotating the cutting blade 5 to perform cutting. A waste collector 9 is located below the cutting blade 5 to collect the cutting debris. To secure the valve stem blank during cutting, a slot with the same width as the outer diameter of the valve stem blank is provided on the side wall of the waste collector 9. During cutting, in addition to being pressed against the clamping seat 7 by the clamping lever 6, the front part of the valve stem blank is also placed in the slot to secure the valve stem blank in the left and right directions. The valve stem blank is secured by clamping from both sides. The waste collector 9 has an upper collector and a lower collector inside. The two layers are separated by a separating mesh to separate the cut debris. The cut block debris is collected in the upper collection chamber, and the lower layer is used to collect metal powder. The separated debris can be recycled or processed in different ways, with a high recycling rate.

[0041] The specific structure and operation of the clamping seat 7 and clamping lever 6 of the cutting part are as follows: The bottom of the mounting column 13 is hinged to the adjusting cylinder 20. The extension and retraction of the adjusting cylinder 20 can adjust the angle between the mounting column 13 and the horizontal plane, and can control the reciprocating movement of the clamping lever 6 in the horizontal direction; The upper end of the mounting column 13 is provided with a vertical elongated hole 131, and the clamping lever 6 is provided with a pin. The pin of the clamping lever 6 is hinged in the elongated hole 131 of the mounting column 13. The elongated hole 131 limits the up and down movement of the clamping lever 6 around the pin; A circular hole 132 is provided below the elongated hole 131, which is hinged to the clamping seat 7 through the pin; The clamping lever 6 is clamped in the middle of the clamping seat 7; A placement port 71 is provided at the end of the clamping seat 7 away from the mounting column 13. The bottom surface of the placement port 71 is an arc surface, and the two sides of the upper end of the placement port 71 are arc surfaces. A placement groove 61 is provided at the corresponding position of the clamping lever 6 and the placement port 71 of the clamping seat 7. The bottom surface 611 of the placement groove 61 is flat and flush with the lowest surface of the bottom surface of the placement port 71. The length of the opening of the placement groove 61 of the clamping lever 6 is greater than the length of the opening of the placement port 71 of the clamping seat 7, which facilitates the removal and fixing of the valve blank during use. The side wall of the placement groove 61 away from the mounting post 13 is higher than the side wall near the mounting post 1, and the upper part of both side walls is an arc surface.

[0042] When a valve stem blank to be processed is placed, it is positioned from above along the arc-shaped surface of the upper end of the clamping seat 7 into the placement opening 71. Then, the adjusting cylinder 20 retracts, causing the mounting post 13 to rotate around the pin connected to the clamping seat 7. This causes the end of the mounting post 13 connected to the adjusting cylinder 20 to move closer to the clamping seat 7, while the end connected to the clamping lever 6 moves away from the clamping seat 7. This, in turn, causes the clamping lever 6 to move closer to the mounting post 13, thus clamping the valve stem blank with the clamping lever 6. When the valve stem blank is pressed down, the valve stem blank is clamped down. After the valve stem blank is processed, the adjusting cylinder 20 extends and drives the mounting column 13 to rotate in the opposite direction around the pin connected to the clamping seat 7 (the opposite direction means that it is the opposite of the rotation direction of the mounting column when the adjusting cylinder retracts). This causes the end of the mounting column 13 connected to the adjusting cylinder 20 to move away from the clamping seat 7, while the end connected to the clamping lever 6 moves towards the clamping seat 7. This, in turn, causes the clamping lever 6 to move away from the mounting column 13, thereby relaxing the clamping lever 6 on the valve stem blank and making the valve stem blank easier to remove.

[0043] The position movement section uses a servo motor, a drive wheel and a driven wheel, and guide rails to adjust the position of the cutting blade 5. Specifically, the first servo motor 14 is vertically positioned, with a first drive wheel 15 above it and a first driven wheel 16 at the same height. A first lead screw is positioned along the axis of the first driven wheel 16, and vertical guide rails are located on both sides of the first driven wheel 16. The first lead screw is connected to the cutting motor 4, which is slidably mounted on the guide rails. Driven by the first servo motor 14, the first drive wheel 15 drives the first driven wheel 16 via a belt (not shown in the figure), which in turn drives the first lead screw to rotate, thereby causing the cutting motor 4 to move vertically along the guide rails, moving it away from or closer to the valve stem blank. During the cutting process, the first servo motor 14 drives the cutting motor 4 downwards to cut the valve stem blank. After cutting, the first servo motor 14 drives the cutting motor 4 upwards, and the cutting blade 5 moves away from the valve stem blank, transferring the valve stem blank. The second servo motor 17 is arranged horizontally, with a second drive wheel 18 on its outer side and a second driven wheel 19 at the same height as the second drive wheel 18. The second driven wheel 19 is provided with a second lead screw in the axial direction, and horizontal guide rails are provided on both sides of the driven wheel. The second lead screw is connected to the connecting plate of the cutting motor 4. The connecting plate of the cutting motor 4 is slidably arranged on the guide rail. Driven by the second servo motor 17, the second drive wheel 18 drives the second driven wheel 19 through a belt (not shown in the figure), which in turn drives the second lead screw to move horizontally, thereby driving the cutting motor 4 to move horizontally along the guide rail, that is, moving horizontally away from or close to the valve stem blank.
