Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, specifically to a bottle clamping device for grinding bottles. Background Technology

[0002] In the sample grinding production line, the sample and grinding rod need to be placed in a grinding bottle, then placed on a grinding machine for rotation. During rotation, the grinding rod grinds the sample. After grinding is complete, the sample and grinding rod are removed. During this process, both the insertion and removal of the sample and grinding rod require opening and closing the grinding bottle.

[0003] When opening or closing a grinding bottle, it is usually necessary to hold the bottle in place while screwing on the cap. If the bottle is secured manually, it is not only time-consuming and labor-intensive, but the process is also difficult to standardize, and the bottle may not be securely held, thus affecting the efficiency of opening and closing the bottle and the seal between the bottle and the cap after closing.

[0004] In view of this, it is necessary to design a bottle clamping device for grinding bottles to solve the above problems. Summary of the Invention

[0005] In view of the technical problems existing in the background art, this application provides a bottle clamping device for grinding bottles, which can easily and efficiently achieve stable clamping of the bottle body.

[0006] This application provides a bottle clamping device for grinding bottles, including a bottle clamping structure and a driving structure;

[0007] The bottle clamping structure includes a first clamping structure and a second clamping structure symmetrically arranged on both sides of the bottle clamping station, and a cavity for accommodating the bottle body for accommodating the grinding bottle is formed between the first clamping structure and the second clamping structure.

[0009] In the technical solution of this application embodiment, by setting a first rack and a second rack meshing with the upper and lower parts of the drive gear respectively, the rotation of the drive gear can synchronously drive the first rack and the second rack to move closer or further apart. Based on this, the bottle body of the grinding bottle is placed on the bottle body clamping station. By adjusting the rotation direction of the drive gear, the two racks are brought closer together, which synchronously drives the two clamping mechanisms to move closer together until they are in close contact with the bottle body, thereby achieving stable clamping of the bottle body; then, by controlling the drive gear to rotate in the opposite direction, the two racks are moved away from each other, which drives the two clamping mechanisms to move away from each other, thereby releasing the bottle body.

The second upper connecting portion is connected to the second base, and the second lower connecting portion is connected to the second rack.

[0017] In this embodiment, the second rack can be stably connected to the second base via the second connector.

[0018] In some embodiments, the bottle clamping device for the grinding bottle further includes a support structure for supporting the bottle clamping structure to perform translational movements; the support structure includes a first support mechanism disposed on the side close to the driving structure and a second support mechanism disposed on the side away from the driving structure.

[0019] In this embodiment, by setting corresponding support structures on both sides near and far from the driving structure, the two sides of the bottle clamping structure can be stably supported so that it can move smoothly under the action of the driving structure.

[0020] In some embodiments, the first support mechanism includes a first guide rod, two first guide sliders slidably connected to the first guide rod, and a first mounting base for fixing the first guide rod; the axial direction of the first guide rod is parallel to the movement direction of the first rack and the second rack; the two first guide sliders are respectively connected to the side of the first base and the second base closer to the drive structure.

[0025] In this embodiment, by moving the telescopic part radially along the bottle body, the protrusion can enter or exit the groove on the side wall of the bottle body, so as to position the rotation angle of the bottle body in the circumferential direction, effectively improving the stability of the clamping process.

[0026] In some embodiments, the bottle positioning mechanism further includes a moving component; the moving component is disposed on one side of the telescopic part, including a second slide extending in a direction perpendicular to the first slide and a positioning slider slidably connected to the second slide; a fixing post is provided at the top of the telescopic part, and an inclined surface facing the fixing part is provided at one end of the positioning slider near the fixing post.

[0041] To achieve stable clamping of the bottle in a simple and efficient manner, this application provides a bottle clamping device for grinding bottles. By setting a driving structure, the bottle clamping structures can move closer or further away synchronously. When the clamping structures are close to each other, the bottle is stably clamped. When clamping is not needed, the bottle can be easily released by driving the clamping mechanisms to move away from each other.

[0042] Specifically, this application provides a bottle clamping device for a grinding bottle, including a bottle clamping structure and a driving structure;

[0043] The bottle clamping structure includes a first clamping structure and a second clamping structure symmetrically arranged on both sides of the bottle clamping station, and a cavity for accommodating the bottle body of the grinding bottle is formed between the first clamping structure and the second clamping structure.

[0044] The drive structure includes a drive gear 131 and a first rack 132 and a second rack 133 that mesh with the drive gear 131 respectively; the first rack 132 is disposed on the upper part of the drive gear 131 and connected to the first clamping structure; the second rack 133 is disposed on the lower part of the drive gear 131 and connected to the second clamping structure.

[0045] In the technical solution of this application embodiment, by setting a first rack 132 and a second rack 133 meshing with the upper and lower parts of the drive gear 131 respectively, the rotation of the drive gear 131 can synchronously drive the first rack 132 and the second rack 133 to move closer or further apart. Based on this, when the bottle body of the grinding bottle is placed on the bottle body clamping station, by adjusting the rotation direction of the drive gear 131 to make the two racks move closer together, the two clamping mechanisms can be synchronously driven to move closer together until they are in close contact with the bottle body, thereby achieving stable clamping of the bottle body; then, by controlling the drive gear to rotate in the opposite direction to make the two racks move away from each other, the two clamping mechanisms can be driven to move away from each other, thereby releasing the bottle body.

[0046] Furthermore, in some embodiments of this application, the drive structure also includes a forward and reverse reversing motor for driving the drive gear 131 to rotate.

[0047] In this embodiment, by using a motor capable of both forward and reverse rotation to drive the drive gear, the rotation direction of the drive gear can be controlled as needed, thereby controlling the movement direction of the two clamping structures to achieve clamping or releasing of the bottle.

[0048] Furthermore, please refer to the following: Figure 1-3 In some embodiments of this application, the bottle clamping device for the grinding bottle can be disposed on the workbench 20. The workbench 20 is provided with a plurality of bottle clamping stations for placing the grinding bottle. Each bottle clamping station corresponds to a bottle clamping device. The center of the cavity formed between the first clamping structure and the second clamping structure in the bottle clamping device is the bottle clamping station. Placing the bottle at the bottle clamping station allows the bottle to be clamped by driving the first clamping structure and the second clamping structure to move closer together synchronously. The number of bottle clamping stations and bottle clamping devices can be set as needed and is not limited to a fixed number. Figure 3 Only two of them are allowed.

[0049] It should be noted that the bottle clamping device provided in this application is used to clamp the bottle body of the grinding bottle and can be applied to any process in the grinding production line that requires bottle clamping. For example, during the opening or closing of the grinding bottle, the bottle clamping device provided in this application can be used to clamp the bottle body, and the cap screwing device can be set to screw the cap to complete the opening and closing operation of the grinding bottle. The cap screwing device may include a cap clamping device, a rotating mechanism connected to the cap clamping device, and a lifting mechanism connected to the rotating mechanism to drive the cap clamping device to rotate and lift. The structure of the cap screwing device described above is only an example, and can be configured as needed; this application is not limited thereto. The bottle clamping device provided in this application can also be used in other processes in the grinding production line besides opening and closing caps; this application is not limited thereto.

[0050] Furthermore, in some embodiments of this application, the first clamping structure includes a first bottle clamping portion 121, and the second clamping structure includes a second bottle clamping portion 122; the opposing sidewalls of the first bottle clamping portion 121 and the second bottle clamping portion 122 are configured as contour-following structures that match the shape of the outer wall of the bottle. For example, when the bottle is cylindrical, the opposing sidewalls of the first bottle clamping portion 121 and the second bottle clamping portion 122 are both configured as arc surfaces that can fit against the outer wall of the bottle. This configuration ensures that the bottle clamping portion is in close contact with the outer wall during clamping, thereby improving the stability of the clamping.

[0051] Furthermore, in some embodiments of this application, the first clamping structure further includes a first base 111, with a first bottle clamping part 121 disposed in the middle of the first base 111; the second clamping structure further includes a second base 112, with a second bottle clamping part 122 disposed in the middle of the second base 112; the first base 111 is connected to the first rack 132 via a first connector 141, and the second base 112 is connected to the second rack 133 via a second connector 142. Preferably, the connection between the first bottle clamping part 121 and the first base 111 is detachable, and the connection between the second bottle clamping part 122 and the second base 112 is also preferably detachable. This configuration allows the rack's movement to drive the corresponding base to translate, thereby driving the corresponding bottle clamping part to translate. Since each bottle clamping part is not directly connected to the corresponding rack, disassembly is more convenient, and it can be replaced according to different bottle shapes.

[0052] Furthermore, in some embodiments of this application, since the first base 111 and the second base 112 are at the same height, while the first rack 132 and the second rack 133 are at different heights, the specific structures of the first connector 141 and the second connector 142 are defined to improve the stability of the connection. The first connector 141 includes a vertically arranged first middle connecting portion, a horizontally arranged first upper connecting portion at the top of the first middle connecting portion, and a horizontally arranged first lower connecting portion at the bottom of the first middle connecting portion. The first upper connecting portion and the first lower connecting portion are respectively located on both sides of the first middle connecting portion. Based on this, the first middle connecting portion is positioned on one side of the first base 111, so that the top surface of the first upper connecting portion is flush with the top surface of the first base 111, and the first lower connecting portion is located below the first base 111. By connecting the first rack 132 to the first upper connecting portion and connecting the first lower connecting portion to the first base 111, the first rack 132 can be stably connected to the first base 111 through the first connector 141.

[0053] Similarly, the second connector 142 includes a vertically arranged second middle connector, a horizontally arranged second upper connector at the top of the second middle connector, and a horizontally arranged second lower connector at the bottom of the second middle connector. The second upper connector and the second lower connector are located on both sides of the second middle connector. By placing the second middle connector on one side of the second base 112, such that the top surface of the second upper connector is located on the upper part of the second base 112, and by connecting the second upper connector to the second base 112 and the second lower connector to the second rack 133, the second rack 133 can be stably connected to the second base 112 through the second connector 142.

[0054] Furthermore, in some embodiments of this application, a support structure is provided to stably support the bottle clamping mechanisms as they move closer or further apart. This support structure includes a first support mechanism located near the driving structure and a second support mechanism located away from the driving structure. By providing corresponding support structures on both sides near and away from the driving structure, the bottle clamping structure can be stably supported on both sides, allowing it to move smoothly under the action of the driving structure.

[0055] More specifically, the first support mechanism includes a first guide rod 151, a first guide slider 152 slidably connected to the first guide rod 151, and a first mounting base 153 for fixing the first guide rod 151. The axial direction of the first guide rod 151 is parallel to the movement direction of the first rack 132 and the second rack 133. Preferably, there are two first guide sliders 152, each connected to the side of the first base 111 and the second base 112 closest to the driving structure. Similarly, the second support mechanism includes a second guide rod 161, a second guide slider 162 slidably connected to the second guide rod 161, and a second mounting base 163 for fixing the second guide rod 161. The axial direction of the second guide rod 161 is parallel to the movement direction of the first rack 132 and the second rack 133. Preferably, there are two second guide sliders 162, each connected to the side of the first base 611 and the second base 612 furthest from the driving structure. With this configuration, when the first rack 132 and the second rack 133 respectively drive the first base 111 and the second base 112 to translate, the end of the first base 111 and the second base 112 closer to the driving structure will translate along the first guide rod 151 under the action of the first guide slider 152, while the end of the first base 111 and the second base 112 farther from the driving structure will translate along the second guide rod 161 under the action of the second guide slider 162. This ensures that the first base 111 and the second base 112 are stably close to or far from each other as a whole, thereby improving the clamping effect on the bottle.

[0056] Furthermore, in some embodiments of this application, the number of first mounting seats 153 is preferably two, with the two first mounting seats 153 respectively disposed at both ends of the first guide rod 151, and can be directly fixed to the worktable. More preferably, the two first mounting seats 153 are respectively located on the outer side below the first base 111 and the second base 112, and the two first guide sliders 152 are respectively connected to the outer side of the bottom surface of the first base 111 and the second base 112, for driving the outer side of the first base 111 and the second base 112 to move. The inner side of the first base 111 and the second base 112 is respectively connected to the first connector 141 and the second connector 142. This arrangement not only provides more stable support for the first guide rod 151, but also makes it easier for the first rack 132 and the second rack 133 to connect to the corresponding base with a shorter length, and the first guide sliders 152 will not interfere with the connection between the first rack 132 and the second rack 133 and the corresponding base.

[0057] Furthermore, in some embodiments of this application, the second support structure further includes a base 164 disposed on the workbench 20, and preferably two second mounting seats 163 are disposed at both ends of the second guide rod 161 and can be directly fixed to the upper surface of the base 164. More preferably, the two second mounting seats 163 are respectively located below the first base 111 and the second base 112, and the two second guide sliders 162 are respectively connected to the inner side of the bottom surface of the first base 111 and the second base 112, for driving the inner side of the first base 111 and the second base 112 to move. With this configuration, the first support structure and the second support structure can be connected to different positions of the first base 111 and the second base 112, further improving the stability of the first base 111 and the second base 112 when moving, and providing a more uniform clamping force, further improving the clamping effect on the bottle.

[0058] Furthermore, in some embodiments of this application, the bottle clamping device 10 further includes a bottle positioning mechanism for initial positioning of the bottle. The bottle positioning mechanism 17 includes a positioning groove 171 disposed on the bottle clamping station for accommodating the bottle. The size of the positioning groove 171 is consistent with the size of the bottom of the bottle so that the bottle can be placed in the positioning groove 171. Several limiting blocks 172 are also disposed on the outside of the positioning groove 171. When the bottle is located in the positioning groove 171, the inner wall of the limiting block 172 contacts the outer wall of the bottle to prevent the bottle from shifting outward.

[0059] Furthermore, in some embodiments of this application, to prevent the bottle body from rotating when the bottle cap rotates, a groove is provided on the side wall at the bottom of the bottle body, and the bottle positioning mechanism 17 further includes an engaging component for engaging with the groove. Specifically, the engaging component is located outside the positioning groove 171 and includes a telescopic part 173 and a fixing part 174 arranged radially along the bottle body. The telescopic part 173 is located on the side near the positioning groove 171 and is slidably connected to a first sliding groove 175 extending radially along the bottle body. A positioning spring 176 that extends radially along the bottle body is provided between the telescopic part 173 and the fixing part 174. A protrusion 1731 extending in the direction of the bottle body is provided on the side of the telescopic part 173 near the positioning groove 171 for engaging with the groove on the side wall of the bottle body. More specifically, when the positioning spring 176 is in its naturally extended state, the protrusion 1731 can engage with the groove of the bottle body; when the telescopic part 173 moves in the direction close to the fixed part 174, so that the protrusion 1731 is located on the radially outer side of the positioning groove 171, the positioning spring 176 is in a compressed state.

[0060] In this way, when the bottle needs to be placed, the telescopic part 173 is moved towards the fixed part 174 by external force, so that the protrusion 1731 is located radially outside the positioning groove 171, and the bottle can be stably placed into the positioning groove 171. Then, the external force compressing the telescopic part 173 is removed, and the positioning spring 176, which is in a compressed state, can continuously apply a force towards the bottle to the telescopic part 173. By rotating the bottle, when it is rotated so that the groove is exactly opposite to the protrusion 1731, the protrusion 1731 enters the groove under the action of the positioning spring 176 and engages with the groove, thereby fixing the bottle. The bottle can be rotated manually or by a robotic arm, or a rotating mechanism can be installed at the bottom of the positioning groove 171 to drive the bottle's rotation. The specific method can be selected according to the actual situation. Preferably, a rotating mechanism is installed at the bottom of the positioning groove 171 to drive the bottom surface of the positioning groove 171 to rotate around the axial direction. With this configuration, when the grinding bottle is placed in the positioning groove 171, the rotating mechanism can drive the grinding bottle to rotate automatically. When the groove at the bottom of the grinding bottle rotates to the position corresponding to the protrusion 1731, the protrusion 1731 can engage with the groove, thereby fixing the bottle and positioning it directionally. In addition, the bottle clamping device provided in this application can also be used in conjunction with the bottle cap screwing device. By directionally positioning the bottle, the corresponding structure on the bottle cap can always be kept in the same position, so that the bottle cap screwing device can accurately position the bottle cap, thereby driving the bottle cap to rotate and realize the opening or closing of the bottle cap.

[0061] Furthermore, in some embodiments of this application, the bottle positioning mechanism 17 further includes a moving component for driving the telescopic part 173 to perform telescopic movement. Specifically, in some embodiments of this application, the moving component is disposed on one side of the telescopic part 173, including a second slide groove 177 extending in a direction perpendicular to the first slide groove 175 and a positioning slider 178 slidably connected to the second slide groove 177; a fixing post 1732 is disposed on the top of the telescopic part 173, and an inclined surface facing the fixing part 174 is disposed at one end of the positioning slider 178 near the fixing post 1732. When the positioning slider 178 slides to the end of the second slide groove 177 near the fixing post 1732, the inclined surface abuts against the fixing post 1732, and the protrusion 1731 is located radially outside the positioning groove 171.

[0062] In this manner, when it is necessary to place or remove the bottle, the positioning slider 178 is moved along the second slide groove 177 until the inclined surface of the positioning slider 178 contacts the fixing post 1732. Then, the positioning slider 178 is moved further along the direction closer to the fixing post 1732. This allows the inclined surface to apply a force towards the fixing part 174 to the fixing post 1732. The fixing post 1732 then drives the telescopic part 173 and its protrusion 1731 to move together towards the fixing part 174, thereby compressing the telescopic part 173. This ensures that the protrusion 1731 is located radially outside the positioning groove 171, facilitating free placement or removal of the bottle. When it is necessary to fix the bottle, the positioning slider 178 is moved away from the fixing post 1732. Under the action of the positioning spring 176, the telescopic part 173 causes the protrusion 1731 to move towards the bottle, engaging with the groove on the side wall of the bottle 10, thus fixing the bottle.

[0063] More specifically, in the embodiments of this application, the number of engaging components can be adjusted according to actual needs, and the number of moving components is consistent with the number of engaging components, so that each engaging component can be controlled separately. Preferably, in some embodiments of this application, two sets of engaging components are symmetrically arranged radially along the bottle body, and the two sets of moving components are arranged on the same side of the engaging components. The positioning sliders 178 in the two sets of moving components are connected by moving brackets 179. Pushing the moving brackets 179 along the extension direction of the second slide groove 177 can simultaneously drive the positioning sliders 178 in the two sets of moving components to move synchronously, thereby driving the two sets of engaging components to move synchronously, achieving efficient positioning of the bottle body. The movement of the moving brackets 179 can be done manually or by a robotic arm, or a corresponding moving mechanism can be set to drive the moving brackets 179 to translate along the extension direction of the second slide groove 177. The specific method can be selected according to the actual situation, and this application is not limited thereto.

[0064] The working process of the grinding bottle clamping device provided in this application is described below:

[0065] When the bottle needs to be clamped, the moving bracket 179 is pushed toward the engaging assembly, causing the positioning slider 178 to move along the second groove 177 toward the fixing post 1732 until the inclined surface of the positioning slider 178 contacts the fixing post 1732. Then, the positioning slider 178 continues to move toward the fixing post 1732, using the inclined surface to apply a force toward the fixing part 174 to the fixing post 1732. In turn, the fixing post 1732 drives the telescopic part 173 and its protrusion 1731 to move toward the fixing part 174 together, so that the protrusion 1731 is located on the radial outside of the positioning groove 171. Then, the grinding bottle is placed in the positioning groove 171 on the worktable 20. The moving bracket 179 then moves the positioning slider 178 away from the fixed post. The compressed positioning spring 176 continuously applies a force towards the bottle to the telescopic part 173. By rotating the bottle, when the groove aligns with the protrusion 1731, the protrusion 1731, under the action of the positioning spring 176, enters the groove and engages with it, thus achieving bottle positioning. Afterwards, the forward and reverse motor is controlled to rotate forward, driving the drive gear 131 to rotate forward (i.e., in...). Figure 2 From the perspective of rotating the drive gear 131 clockwise, the first rack 132 and the second rack 133 are driven to move closer to each other, thereby driving the first bottle clamping part 121 and the second bottle clamping part 122 to move closer to each other along the corresponding guide rods until the first bottle clamping part 121 and the second bottle clamping part 122 are in close contact with the bottle, thus achieving stable clamping of the bottle.

[0066] If it is necessary to release the bottle, the forward and reverse motor is controlled to reverse, driving the drive gear 131 to rotate in the opposite direction. This synchronously drives the first rack 132 and the second rack 133 to move away from each other, thereby causing the first bottle clamping part 121 and the second bottle clamping part 122 to move away from each other along the corresponding guide rods. This prevents the first bottle clamping part 121 and the second bottle clamping part 122 from contacting the bottle, at which point the bottle is released from the clamp. Then, the positioning slider 178 is moved along the second slide groove 177 towards the fixing post 1732, causing the protrusion 1731 to move towards the fixing part 174 until the protrusion 1731 is completely disengaged from the groove of the bottle, at which point the bottle can be removed.

The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
