Description

Technical Field

[0001] This utility model relates to the field of disc tool magazine technology, and in particular to a disc tool magazine including a mechanical valve fixing structure. Background Technology

[0002] Dust adheres to cutting tools when they are installed in a disc tool magazine. This dust, along with the cutting fluid adhering to the tool, easily sticks to the tool, causing contamination. A dirty tool holder can affect positioning accuracy and contaminate the position where the tool tip is held in the tool holder. Therefore, our company has developed a disc tool magazine with a dust removal function. It uses compressed air to spray and clean the tool. A mechanical valve is installed on the rotating tool disc. The rotation of the tool disc is linked to the alternating opening of the mechanical valve. When it is open, compressed air is delivered to spray and clean the tool.

[0003] Currently, the motor protective housing of the tool magazine is equipped with a support plate on top, and the mechanical valve is mounted on the upper surface of the support plate. In order to prevent the screws from loosening and falling off, the mechanical valve fixing screws are fixed from top to bottom. When disassembling and assembling the mechanical valve, the tool disc above needs to be disassembled, which makes the disassembly and maintenance of the mechanical valve inconvenient.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] Please refer to Figure 1-5 As a specific implementation, the technical solution of this utility model is as follows: a disc-type tool magazine including a mechanical valve fixing structure, comprising a protective housing 1, a tool disc 10 rotatably disposed above the protective housing 1, and a support plate 12 disposed on the protective housing 1 and located between the tool disc 10 and the protective housing 1, and further comprising:

[0034] The connecting plate 20 is detachably and fixedly connected to the support plate 12, and a mechanical valve 2 is detachably installed on the upper surface of the connecting plate 20.

[0035] Specifically, it should be noted that the reference is... Figures 1-5 The disc-type tool magazine provided in this application includes a protective housing 1, in which a drive motor is installed. A rotating component 11 is rotatably mounted on the top of the protective housing 1. The rotating component 11 is driven and connected to the output shaft of the drive motor. The tool disc 10 is detachably and fixedly mounted on the rotating component 11, thereby realizing the drive of the tool disc 10 to rotate around a vertical axis to meet the tool changing requirements. The above structure and working method are the conventional settings of the disc-type tool disc 10 in the prior art. Other components of the disc-type tool magazine will not be described in detail here, and those skilled in the art should understand. A support plate 12 is detachably fixed to the top of the protective housing 1. A trigger plate 21 is detachably fixed to the rotating component 11. Multiple protrusions are evenly spaced on the outer circumference of the trigger plate 21, and the gap between two adjacent protrusions corresponds to the tool mounting position on the cutter head 10. A mechanical valve 2 is mounted on the support plate 12. The mechanical valve 2 includes a valve body and a swing arm 2a. A rolling element 2b is provided at the end of the swing arm 2a. When the cutter head 10 rotates, the protrusions of the trigger plate 21 abut against the rolling element 2b, pressing the rolling element 2b and driving the swing arm 2a to swing, thus triggering the mechanical valve 2. When the rolling element 2b corresponds to the gap between two adjacent protrusions, the rolling element 2b is not compressed, and the mechanical valve... 2. The mechanical valve 2 returns to its original position, thereby switching its state. When the cutter head 10 stops rotating, the mechanical valve 2 is in the closed state. When the cutter head 10 rotates, the mechanical valve 2 is repeatedly opened, thereby spraying and cleaning the cutter to achieve a dust removal effect. This application does not protect the cleaning structure, and the cleaning structure is not an improvement point of this application, so it will not be described in detail here. The improvement of this application is that a connecting plate 20 is detachably fixedly connected to the support plate 12, and the mechanical valve 2 is detachably fixedly mounted on the upper surface of the connecting plate 20. With this setting, when the mechanical valve 2 needs to be replaced or maintained, the connecting plate 20 can be removed together to disassemble the mechanical valve 2, which is convenient for installation, replacement and maintenance.

[0036] Furthermore, as a specific implementation, one end of the connecting plate 20 is hinged to the support plate 12, and the other end is provided with a second flange plate 201. The support plate 12 is provided with a first flange plate 122 adapted to the second flange plate 201. The first flange plate 122 and the second flange plate 201 are detachably and fixedly connected.

[0037] For details, please refer to Figures 7-13 Along a direction perpendicular to the plate surface, the connecting plate 20 is provided with two second ear plates 203 spaced apart, and the support plate 12 is provided with a first ear plate 120. The first ear plate 120 can extend between the two second ear plates 203, and then a hinge rod 23 passes through the first ear plate 120 and the second ear plate 203 to form a hinged connection. The support plate 12 is provided with an arc-shaped first positioning surface 121, and the connecting plate 20 is provided with an arc-shaped second positioning surface 2012 adapted to the first positioning surface 121. When installing the connecting plate 20, it is first connected by a hinge... The connecting rod 23 connects the connecting plate 20 to the support plate 12. Then, the connecting plate 20 is rotated so that the first positioning surface 121 abuts against the second positioning surface 2012. Then, the connecting plate 20 is fixed by threading the screw through the second flange plate 201 and threading it into the threaded hole 2202 on the first flange plate 122. During installation, the second flange plate 201 can be placed in a position that is easy to observe, such as the side of the tool, so as to facilitate observation of the tightening status of the screws connecting the first flange plate 122 and the second flange plate 201, which is convenient for daily inspection.

[0038] Furthermore, as a preferred embodiment, the axis of the hinge shaft at the hinge joint of the connecting plate 20 and the support plate 12 is vertically arranged, and both the first flange plate 122 and the second flange plate 201 are vertically arranged. This arrangement facilitates the assembly and disassembly of the connecting plate 20 and the support plate 12.

[0039] Furthermore, as a preferred embodiment, refer to Figure 10 A positioning plate 2011 is provided parallel to and spaced apart from one of the first flange plate 122 and the second flange plate 201. The two adjacent surfaces of the positioning plate 2011 are perpendicular to the hinge axis, and the two surfaces are positioned and engaged with the upper and lower end faces of the other side of the first flange plate 122 and the second flange plate 201. In a specific embodiment, the positioning plate 2011 is provided on the second flange plate 201 and is integrally formed. By providing the positioning plate 2011, when the first flange plate 122 and the second flange plate 201 are connected, the two positioning plates 2011 are located on the upper and lower sides of the first flange plate 122 and are positioned with the upper and lower surfaces of the first flange plate 122, thereby ensuring the reliability of the connection between the connecting plate 20 and the support plate 12.

[0040] Furthermore, as a preferred embodiment, the connecting plate 20 and the support plate 12 are hinged together by a hinge rod 23, and a connecting sleeve 220 is provided coaxially with the upper surface of the support plate 12 and the hinge rod 23. The upper end of the hinge rod 23 is threadedly connected to the connecting sleeve 220.

[0041] For details, please refer to Figures 6-10 , Figures 12-15 A connector 22 is detachably fixed to the upper surface of the support plate 12. The connector 22 includes a connecting sleeve 220 coaxially arranged with the first ear plate 120. The connecting sleeve 220 has a threaded hole 2202 inside. The upper end of the hinge rod 23 has a threaded section 231 that is threaded to the threaded hole 2202. The lower end of the hinge rod 23 has an end 233. When installing the hinge rod 23, it can pass through the second ear plate 203 and the first ear plate 120 from bottom to top and then be threaded to the threaded hole 2202. After the threaded connection, the pin section 230 in the middle area of ​​the hinge rod 23 cooperates with the second ear plate 203 and the first ear plate 120. This method facilitates the disassembly and installation of the hinge rod 23, thereby making it easier to disassemble and assemble the connecting plate 20.

[0042] Furthermore, the hinge rod 23 includes a pin section 230 and a threaded section 231. The radius of the threaded section 231 is smaller than that of the hinge section. The connecting sleeve 220 includes a guide hole 2201 that guides and cooperates with the pin section 230. The outer circumferential surface of the pin section 230 is provided with a first arc-shaped groove 234. A positioning rod 24 is radially floatingly disposed on the side wall of the guide hole 2201.

[0043] Understandably, the disc-type tool magazine's tool head 10 requires frequent position switching during operation, which can easily cause the screws to loosen. To improve safety, refer to... Figures 6-10 , Figures 12-15 The connecting plate 20 is provided with an arc-shaped plate 202 coaxially arranged with the second ear plate 203. When installing the connecting plate 20, first align the first ear plate 120 and the second ear plate 203, and move the first positioning surface 121 and the second positioning surface 2012 away from each other. At this time, the arc-shaped plate 202 is staggered with the radial hole 221 on the side wall of the guide hole 2201. Then, the hinge rod 23 passes through the first ear plate 120 and the second ear plate 203 from bottom to top and is threadedly connected to the connecting sleeve 220. After the connecting sleeve 220 is threadedly connected to pin 23, the hinged section extends into the guide hole 2201. The second end face 232 of the hinged section abuts against the first end face 222 of the guide hole 2201 for limitation. At this time, the first arc groove 234 on the pin section 230 corresponds exactly to the positioning rod 24. Then, the connecting plate 20 is rotated so that the first positioning surface 121 and the second positioning surface 2012 abut against each other. The connecting plate 20 is fixed by the first flange plate 122 and the second flange plate 201. At this time, the arc plate 202 is in a position where... Figure 13As shown, the arc plate 202 blocks the end of the radial hole 221, thereby positioning the positioning rod 24 and causing the end of the positioning rod 24 to extend into the first arc groove 234, thereby positioning the hinge rod 23. This effectively prevents the hinge rod 23 from falling off and improves safety. When disassembling the connecting plate 20, the first flange plate 122 and the second flange plate 201 need to be separated first. Rotate the first flange plate 122 to move the first positioning surface 121 away from the second positioning surface 2012, and the arc plate 202 leaves the radial hole 221. At this time, the hinge rod 23 can be disassembled.

[0044] Furthermore, as a preferred implementation method, refer to Figure 15 The guide hole 2201 has a radial hole 221 on its sidewall. The positioning rod 24 is guided and engaged with the radial hole 221. A flange 2210 is provided in the middle region of the radial hole 221. The positioning rod 24 includes a reduced-diameter section 240 that engages with the inner circumferential surface of the flange 2210. A limiting member is provided on the outer circumferential surface of the reduced-diameter section 240 that engages with the flange 2210. Specifically, by providing the flange 2210 and the reduced-diameter section 240 of the positioning rod 24, in use, the limiting member is provided on the side of the reduced-diameter section 240 away from the guide hole 2201 of the flange 2210. The limiting member can axially position the positioning rod 24, preventing the positioning rod 24 from separating from the connecting sleeve 220.

[0045] Furthermore, preferably, the outer peripheral surface of the reduced diameter section 240 is provided with a second arc-shaped groove 241, and the limiting member is a rubber ring 25 disposed within the second arc-shaped groove 241. Specifically, when the rubber ring 25 is installed in the second arc-shaped groove 241, it can protrude from the outer peripheral surface of the reduced diameter section 240, and the protruding part can limit the flange 2210. Thus, the rubber ring 25 is the limiting member, and with this arrangement, the rubber ring 25 is easy to assemble.

[0046] Furthermore, as a specific implementation, an arc-shaped plate 202 is provided on the connecting plate 20 to mate with the outer peripheral surface of the connecting sleeve 220. Specifically, the arc-shaped plate 202 can be integrally formed with the connecting plate 20 by welding.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
