Description

Technical Field

[0001] This application relates to the field of grinding machine protective equipment technology, and in particular to a protective screen for use when grinding with a grinding machine. Background Technology

[0002] Grinding machines are machine tools that use grinding wheels to grind the surface of workpieces. They can perform high-precision machining of various metallic and non-metallic materials through the rotation and feed motion of grinding wheels and other grinding tools to obtain the desired shape, size, and surface finish. Grinding machines have wide applications in machinery manufacturing, the automotive industry, aerospace, and other fields.

[0003] Existing grinding machines are machine tools that use abrasive tools to grind the surface of workpieces. During the grinding process, the friction between the abrasive tool and the workpiece can cause material to peel off and break, thus generating a certain amount of debris.

[0004] The existing technical solutions mentioned above have the following drawbacks: the range of debris scattering to the surrounding area is uncontrollable, and cleaning is quite troublesome. Utility Model Content

[0005] In order to reduce the range of debris emitted from a grinding machine and facilitate cleaning, this application provides a protective screen for use when grinding.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A protective screen for use when grinding with a grinding machine includes a support frame, a base, and a protective net. The support frame is connected to the base, and the base is placed on the working surface to provide stable support for the support frame. The protective net is embedded in the support frame, which supports the protective net. The protective net is used to block debris and reduce the range of debris dispersion.

[0008] By adopting the above solution, the protective screen is placed around the grinding machine, which can block the debris generated during the grinding process, thereby reducing the range of debris dispersion and making it easier to clean.

[0009] Furthermore, each of the support frames includes a first connecting portion and a second connecting portion, wherein the first connecting portion is inserted into and engaged with the adjacent second connecting portion.

[0010] By adopting the above scheme, because a first connecting part and a second connecting part are set, adjacent support frames can be spliced ​​together, and the protection area of ​​the protective screen can be controlled by increasing or decreasing the number of support frames.

[0011] Furthermore, the first connecting part is a T-shaped insertion slot, and the second connecting part is a insertion assembly. The insertion assembly includes a first insertion plate, a second insertion plate, and an elastic member. The elastic member is disposed between the first insertion plate and the second insertion plate, and both ends of the elastic member are fixedly connected to the first insertion plate and the second insertion plate, respectively. After controlling the elastic member to be in a contracted state, the first insertion plate and the second insertion plate are both inserted into the T-shaped insertion slot. Then, the control of the elastic member is released, and the elastic member extends under its own elastic action. The first insertion plate and the second insertion plate move in directions away from each other, and both the first insertion plate and the second insertion plate abut against the two sides of the T-shaped insertion slot, so that the entire insertion assembly cannot be dislodged from the T-shaped insertion slot.

[0012] By employing the above-described scheme, the first and second plug-in plates are pinched together in a direction that brings them closer to each other, allowing them to be inserted into the T-shaped plug-in slot. Once the first and second plug-in plates are fully inserted into the T-shaped plug-in slot, they are released. Under the action of the elastic element, the first and second plug-in plates move in opposite directions. Because the T-shaped plug-in slot has a misalignment, when the elastic element pushes the first and second plug-in plates in opposite directions under its own elasticity, the distance between the first and second plug-in plates increases. The entire plug-in assembly is misaligned and locked, preventing it from detaching from the T-shaped plug-in slot. This connects the support frame to the adjacent support frame.

[0013] Furthermore, both the first and second plug-in plates are provided with threaded holes, and the two threaded holes are opposite each other. A set screw is provided between the two threaded holes. Rotating the set screw can control the first and second plug-in plates to move closer or further apart.

[0014] By adopting the above scheme, the rotation of the set screw can control the relative proximity or distance between the first and second plug plates, facilitating the insertion and engagement of the first and second plug plates with the T-shaped plug slot.

[0015] Furthermore, a placement groove is provided on the back of the support frame, and a connecting frame is fixedly connected around the protective net. The connecting frame is used to support the protective net and is inserted into the placement groove. A locking component is provided on the side wall of the support frame. The locking component is used to lock the relative state of the connecting frame and the placement groove after they are inserted into each other.

[0016] By adopting the above scheme, the connecting frame is used to support the protective net; because a placement slot is provided, when the connecting frame is inserted into the placement slot, the protective net is inserted into the support frame; and because a locking component is provided, the locking component can lock the insertion state of the connecting frame and the placement slot, that is, it can lock the connection state of the protective net and the support frame.

[0017] Furthermore, the locking assembly includes a locking frame, a pusher, a locking pin, and a limiting member. The locking frame is connected to the support frame. One end of the pusher is fixedly connected to the locking frame, and the other end of the pusher is connected to the locking pin. The locking pin is used to limit the insertion state of the connecting frame and the placement slot. The limiting member is generally L-shaped. One end of the limiting member is rotatably connected to the support frame. The side wall of the limiting member is used to support the side of the locking pin away from the pusher. When the limiting member abuts against the locking pin, the pusher is in a retracted state.

[0018] By adopting the above scheme, when the limiting member abuts against the locking pin, the pushing member is in a retracted state. At this time, the locking pin is completely disengaged from the placement groove, and the locking pin cannot lock the insertion state of the connecting frame and the placement groove. Rotating the limiting member causes the limiting member to disengage from the locking pin. At this time, the pushing member pushes the locking pin to move under its own elasticity until the side wall of the locking pin completely covers the placement groove. In this way, the insertion state of the connecting frame and the placement groove can be locked.

[0019] Furthermore, a handrail frame is fixedly connected to the side of the protective net that is away from the bottom wall of the placement trough.

[0020] By adopting the above solution, the handrail frame is designed to facilitate the removal of the protective netting from the placement slot.

[0021] Furthermore, the base includes a base plate and four support legs. One side of the base plate is fixedly connected to the support frame, and the other side of the base plate is fixedly connected to each support leg. The support legs are used to abut against the working surface, and each support leg has an anti-slip pad fixedly connected to the side closest to the working surface.

[0022] By adopting the above solution, the anti-slip pad can increase the friction between the support leg and the working surface, thus increasing the friction between the base and the working surface and making the contact between the base and the working surface more stable.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up this protective screen and placing it around the periphery of the grinding machine, the debris generated during the grinding process can be blocked, thereby reducing the range of debris dispersion and making it easier to clean.

[0025] 2. By setting the first connecting part and the second connecting part, adjacent support frames can be spliced ​​together, and the protection area of ​​the protective screen can be controlled by increasing or decreasing the number of support frames;

[0026] 3. By setting a set screw, the movement of the first and second plug-in plates closer or further apart can be controlled. Attached Figure Description

Detailed Implementation

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1 This embodiment provides a protective screen for use when grinding with a grinding machine, including a support frame 1, a base 2 and a protective net 3. The support frame 1 is fixedly connected to the base 2, and the base 2 is placed on the working surface to provide stable support for the support frame 1. The protective net 3 is embedded in the support frame 1, and the support frame 1 is used to support the protective net 3. The protective net 3 is used to block the debris generated when the grinding machine is working, thereby reducing the range of debris dispersion.

[0036] Reference Figure 1 Each support frame 1 includes a first connecting part 11 and a second connecting part 12 on both sides. The first connecting part 11 is used to connect with the second connecting part 12 of the adjacent support frame 1, so that the protection range of the protective net 3 can be adjusted by increasing or decreasing the number of support frames 1.

[0037] Reference Figures 2-3The first connecting part 11 is a T-shaped insertion slot, and the second connecting part 12 is an insertion assembly. The insertion assembly includes a first insertion plate 121, a second insertion plate 123, and a plurality of elastic elements 122. The plurality of elastic elements 122 are linearly and uniformly arranged between the first insertion plate 121 and the second insertion plate 123. Both ends of each elastic element 122 are fixedly connected to the first insertion plate 121 and the second insertion plate 123, respectively. By controlling the extension and retraction of the elastic elements 122, the distance between the first insertion plate 121 and the second insertion plate 123 can be controlled. In this embodiment, the elastic element 122 is preferably a spring. Specifically, the connection method between the entire insertion assembly and the support frame 1 is as follows: a connecting strip is fixedly connected to the middle of each elastic element 122, and the other end of each connecting strip is fixedly connected to the support frame 1.

[0038] Reference Figure 4 In this embodiment, the first plug plate 121 and the second plug plate 123 have the same length and both are longer than the length of the T-shaped plug slot. Specifically, when the first plug plate 121 and the second plug plate 123 are inserted into the T-shaped plug slot, both ends extend beyond the T-shaped plug slot. For ease of understanding, in this embodiment, the portions of the first plug plate 121 and the second plug plate 123 that extend beyond the T-shaped plug slot are named adjustment portions, so that each end of the first plug plate 121 and the second plug plate 123 corresponds to an adjustment portion.

[0039] Reference Figure 1 and Figure 4 Each adjustment part is provided with a threaded hole, and the threaded holes on both ends of the first plug plate 121 and the two ends of the second plug plate 123 correspond to each other to form a through groove. In this embodiment, there are two through grooves, and each through groove is threaded with a set screw 4. By adjusting the relative position relationship between the set screw 4 and each through groove, the first plug plate 121 and the second plug plate 123 can be controlled to move closer or further away from each other.

[0040] Reference Figures 1-4Specifically, the T-shaped insertion groove increases in width from the side away from the side wall of the connecting frame 31 to the side closer to the side wall of the connecting frame 31. Furthermore, there is a misalignment boundary during the process of the T-shaped insertion groove opening increasing in size. Therefore, when the insertion assembly is inserted into the T-shaped insertion groove of the adjacent support frame 1, the two set screws are rotated until the first insertion plate 121 and the second insertion plate 123 approach each other until the elastic element 122 contracts to its minimum. At this point, the entire insertion assembly is fully inserted into the bottom wall of the T-shaped insertion groove. Then, the two set screws 4 are rotated until both set screws 4 are dislodged through the through groove. In this state, several elastic elements 122 extend under their own elastic elements 122. The opposing sides of the first insertion plate 121 and the second insertion plate 123 are respectively fixedly connected to the two sides of the T-shaped insertion groove. That is to say, the overall width of the insertion assembly increases. Because there is a misalignment in the T-shaped insertion groove, the insertion assembly cannot be dislodged through the T-shaped insertion groove, thus connecting the connecting frame 31 to the adjacent connecting frame 31.

[0041] Reference Figure 1 The protective net 3 is covered with a connecting frame 31, and the protective net 3 is fixedly connected to the connecting frame 31 on all four sides. The support frame 1 has a placement groove on the side away from the grinding machine. The connecting frame 31 is inserted into the placement groove. The outer wall of the placement groove is provided with a locking component 5 for limiting the insertion state of the connecting frame 31 and the placement groove. The protective net 3 is fixedly connected to a handrail frame 32 on the side away from the grinding machine. In this embodiment, the protective net 3 has a certain degree of rigidity.

[0042] Reference Figure 1 , Figures 4-6In this embodiment, the support frame 1 is rectangular in shape, and four locking components 5 are provided, so that each pillar of the support frame 1 is provided with a corresponding locking component 5. Each locking component 5 includes a locking frame 51, a pushing member 52, a locking pin 53, and a limiting member 54. The locking frame 51 is L-shaped in shape, and one end of the locking frame 51 is fixedly connected to the side wall of the support frame 1. One end of the pushing member 52 is fixedly connected to the bottom wall of the locking frame 51, and the other end of the pushing member 52 is connected to the locking pin 53. When there is no external force, the pushing member 52 pushes the locking pin 53 to move towards the center of the protective net 3, so that the side wall of the locking pin 53 completely covers the opening of the placement slot. In this way, the insertion state of the connecting frame 31 and the placement slot can be limited. The limiting member 54 is L-shaped in shape, and one end of the limiting member 54 is rotatably connected to the support frame 1. Next, the side wall of the limiting member 54 is used to support the side of the locking pin 53 away from the pushing member 52. When the limiting member 54 supports the locking pin 53, the locking pin 53 is completely separated from the groove of the placement groove, and the pushing member 52 is in a retracted state. At this time, the connecting frame 31 and the placement groove are in an unlocked state. In this embodiment, the pushing member 52 is preferably a spring, and the rigidity of the spring is selected according to the actual situation on site. It can meet the requirement that when the debris hits the protective net 3 during the flying process, the elastic member 122 will not bend. Specifically, each pushing member 52 is provided with a telescopic groove, and each connecting frame is fixedly connected to the corresponding telescopic groove with a telescopic rod. The telescopic rod is set inside the pushing member 52 and is coaxially set with the pushing member 52. When the pushing member 52 extends or retracts, the telescopic rod moves back and forth along the telescopic groove.

[0043] Reference Figures 1-2 The base 2 includes a base plate 21 and four support legs 22. One side of the base plate 21 is fixedly connected to the support frame 1, and the support legs 22 are fixedly connected to the other side of the base plate 21. The four support legs 22 are located at the four corners of the base plate 21. The support legs 22 are used to abut against the working surface, and each support leg 22 is fixedly connected to an anti-slip pad 221 on the side closest to the working surface.

[0044] The specific implementation principle of a protective screen used in a grinding machine according to an embodiment of this application is as follows: The connecting frame 31 is inserted into the placement slot, and then each limiting member 54 is manually rotated sequentially to separate each limiting member 54 from the locking pin 53. Then, under the action of the pushing member 52, each locking pin 53 moves towards the center of the protective net 3 until the sidewall of each locking pin 53 completely covers the opening of the placement slot, thus locking the insertion state of the connecting frame 31 into the placement slot. The number of support frames 1 is determined according to the required protection length, and then the protective net 3 is connected to each support frame 1 in the manner described above. Then, two adjacent support frames... The frames 1 are connected together. Specifically, the two set screws 4 are rotated until the first plug plate 121 and the second plug plate 123 are close to each other until the elastic element 122 is contracted to its minimum. At this time, the entire plug assembly is fully inserted into the bottom wall of the adjacent T-shaped plug groove. Then, the two set screws 4 are rotated until both set screws 4 are dislodged through the through groove. In this state, several elastic elements 122 extend under their own elastic elements 122, so that the opposite ends of the first plug plate 121 and the second plug plate 123 respectively abut against the two sides of the T-shaped plug groove. In this state, the entire plug assembly cannot be dislodged through the T-shaped plug groove, thereby completing the connection of the two adjacent support frames 1.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
