Description

Technical Field

[0001] This utility model relates to the field of hydraulic clamping technology, specifically a hydraulic clamping tool for mining machinery processing. Background Technology

[0002] In mining machinery processing, workpieces are typically clamped to ensure machining accuracy and quality. Therefore, fixtures are an indispensable tool in mining machinery processing. Currently, the most common fixtures on the market are mechanical fixtures and hydraulic fixtures. Hydraulic fixtures use hydraulic components to replace mechanical parts to automatically position, support, and clamp workpieces. Hydraulic fixtures can ensure accurate positioning and secure clamping of workpieces in specified positions. Compared to mechanical fixtures, hydraulic fixtures have advantages such as greater clamping force and ease of operation, and are therefore widely used in mining machinery processing.

[0003] Patent document CN219582273U discloses a hydraulic clamp for mining machinery processing, including a housing. A motor is fixedly connected to the bottom left side of the housing, and a lead screw is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the left side of the lead screw, and a connecting rod is fixedly connected to the bottom of the threaded sleeve. Brake pads are fixedly connected to the front and rear ends of the left side of the connecting rod, and connecting wheels are fixedly connected to the front and rear ends of the bottom left side of the housing. This utility model solves the problems of existing hydraulic clamps being inconvenient to move and clamp materials of different sizes during operation, thus failing to meet usage requirements. However, the existing technology still has shortcomings.

[0004] In existing hydraulic clamps, the housing and clamping plates used to hold mining machinery parts cannot rotate independently. During use, the clamping plates are driven by a hydraulic cylinder to move closer together to fix the parts. After processing one side of the part, if it is necessary to process the opposite or adjacent side of the part, the part needs to be removed from between the two clamping plates, and then manually rotated and re-clamped. This makes the hydraulic clamps quite limited, thus affecting the processing efficiency of mining machinery parts.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a hydraulic clamp for mining machinery processing.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a hydraulic clamp for mining machinery processing, comprising:

[0008] The base has a support fixedly connected to its top;

[0009] A placement tray, wherein the placement tray is disposed on top of the support base;

[0010] A rotating structure is provided on the top of a support base. The rotating structure includes a motor fixedly installed on the top of the base. The output end of the motor is fixedly connected to a rotating shaft. The rotating shaft is rotatably connected to the support base. The top end of the rotating shaft extends to the top of the support base and the end is fixedly connected to the bottom of the placement tray. An annular groove is provided on the top of the support base. An annular slide is fixedly connected to the bottom of the placement tray. Several balls are installed on the bottom of the annular slide. The annular slide is slidably connected to the annular groove through the balls.

[0011] The flipping structure is located at both ends of the top of the base. The flipping structure includes a hydraulic push rod 1 fixedly installed at both ends of the top of the base. A vertical plate is fixedly connected to the top of the output end of the hydraulic push rod 1. A motor 2 is fixedly installed at the upper end of the opposite side of the vertical plate. A rotating shaft 2 is fixedly connected to the output end of the motor 2. The rotating shaft 2 is rotatably connected to the vertical plate. One end of the rotating shaft 2 extends to the opposite side of the vertical plate and a mounting plate is fixedly connected to the end of the shaft.

[0012] A clamping structure is provided at both ends of the placement tray;

[0013] A movable structure is located at the bottom of the base.

[0014] Furthermore, an annular groove II is provided on the upper end of the opposite side of the upright plate, and a connecting rod is fixedly connected to the opposite side of the mounting plate. There are multiple connecting rods distributed in a circle, and ball bearings II are installed at the ends of the connecting rods. The connecting rods are slidably connected to the annular groove II through the ball bearings II. Guide rods are fixedly connected to both ends of the top of the base, and the upright plate is slidably connected to the guide rods.

[0015] Furthermore, the clamping structure includes:

[0016] Hydraulic push rod two, which is fixedly installed on one side of the mounting plate;

[0017] A clamping plate, which is fixedly connected to the output end of the hydraulic push rod two;

[0018] A rubber pad is fixedly connected to one side of the clamping plate.

[0019] Furthermore, the movable structure includes:

[0020] Support columns, which are fixedly connected to the four corners of the bottom of the base;

[0021] Hydraulic push rod three, which is fixedly installed on the top of the inner wall of the support column;

[0022] A movable plate is fixedly installed at the bottom of the three output ends of the hydraulic push rod.

[0023] Shock-absorbing casters are fixedly installed at the bottom of the movable plate.

[0024] Furthermore, a limiting groove is provided at the lower part of both ends of the inner wall of the support column, and a limiting block is fixedly connected to both ends of the movable plate, with the limiting block slidably connected in the limiting groove.

[0025] The advantages of this utility model compared with the prior art are as follows: Through the design of the rotating and flipping structures, the first motor drives the first rotating shaft and the placement plate to rotate, thereby adjusting the placement angle of the mining machinery parts placed on top of the placement plate. The second hydraulic push rod moves the clamping plates closer together, clamping and fixing both ends of the parts. The first hydraulic push rod moves the upright plate upward, moving the clamped parts upward. The second motor drives the second rotating shaft to rotate, which in turn rotates the mounting plate, causing the clamping plates and the clamped parts to flip. This achieves omnidirectional rotation of the parts placed on the placement plate, facilitating processing on opposite or adjacent sides of the parts without manual rotation, simplifying the processing of mining machinery parts, improving processing efficiency, and demonstrating good practicality.

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 5 As shown, this embodiment proposes a hydraulic clamp for mining machinery processing, including a base 1, a support seat 2 fixedly connected to the top of the base 1, and a placement plate 3 provided on the top of the support seat 2. The support seat 2 has a U-shaped structure, and the mining machinery parts are placed on the top surface of the placement plate 3 during processing.

[0035] The support base 2 has a rotating structure 4 on its top. The rotating structure 4 includes a motor 41 fixedly installed on the top of the base 1. The output end of the motor 41 is fixedly connected to a rotating shaft 42. The rotating shaft 42 is rotatably connected to the support base 2. The top end of the rotating shaft 42 extends to the top of the support base 2 and the end is fixedly connected to the bottom of the placement tray 3. The top of the support base 2 has an annular groove 43. The bottom of the placement tray 3 is fixedly connected to an annular slide 44. Several balls 45 are installed at the bottom of the annular slide 44. The annular slide 44 is slidably connected to the annular groove 43 through the balls 45. When the motor 41 is started, the rotating shaft 42 is driven to rotate. The rotating shaft 42 drives the placement tray 3 to rotate. When the placement tray 3 rotates, it will drive the annular slide 44 to rotate in the annular groove 43 through the balls 45. This helps to relieve the pressure of the placement tray 3 on the rotating shaft 42, making the rotation of the placement tray 3 more stable and improving its service life. This allows for adjustment of the placement angle of the mining machinery parts placed on the top of the placement tray 3.

[0036] The base 1 has flip structures 5 at both ends of its top. Each flip structure 5 includes a hydraulic push rod 51 fixedly installed at both ends of the top of the base 1. The hydraulic push rod 51 is connected to an external hydraulic system. Since the hydraulic system is common knowledge in the field and not an improvement in this invention, it will not be described in detail here. A vertical plate 52 is fixedly connected to the top of the output end of the hydraulic push rod 51. A motor 53 is fixedly installed on the upper end of the opposite side of the vertical plate 52. A motor frame is provided on the outside of the motor 53, and the motor frame is fixedly connected to the surface of the vertical plate 52. A rotating shaft 54 ​​is fixedly connected to the output end of the motor 53. The rotating shaft 54 ​​is rotatably connected to the vertical plate 52. One end of the rotating shaft 54 ​​extends to the opposite side of the vertical plate 52, and a mounting plate 55 is fixedly connected to the end of the shaft. An annular groove 56 is provided on the upper end of the opposite side of the vertical plate 52. A connecting rod 57 is fixedly connected to the opposite side of the mounting plate 55. Multiple connecting rods 57 are arranged circumferentially. Each connecting rod 57 has a ball bearing 58 at its end. The connecting rods 57 are slidably connected to the annular groove 56 via the ball bearings 58. The arrangement of the annular groove 56, connecting rods 57, and ball bearings 58 helps to alleviate the pressure on the rotating shaft 54 ​​when the mounting plate 55 rotates, making the mounting plate 55 more stable during rotation. Guide rods 59 are fixedly connected to both ends of the top of the base 1. The upright plate 52 is slidably connected to the guide rods 59. The guide rods 59 facilitate the limiting and guiding of the movement of the upright plate 52. Activating the hydraulic push rod 51 moves the upright plate 52 upward, thereby moving the clamped parts upward. Activating the motor 53 rotates the rotating shaft 54, which in turn rotates the mounting plate 55, causing the clamped parts to flip, thus realizing the rotation of the parts placed on the placement tray 3 and facilitating the turning of the parts.

[0037] The placement tray 3 has clamping structures 6 at both ends. The clamping structures 6 include a hydraulic push rod 61 fixedly installed on the opposite side of the mounting plate 55. The hydraulic push rod 61 is connected to an external hydraulic system. Since the hydraulic system is common knowledge in the field and is not an improvement in this case, it will not be described in detail here. The output end of the hydraulic push rod 61 is fixedly connected to a clamping plate 62. The bottom of the hydraulic push rod 61 is equipped with a support plate. One end of the bottom of the clamping plate 62 is provided with a limiting rod. One end of the limiting rod is slidably connected to the inside of the support plate. The limiting rod is set to limit and guide the movement of the clamping plate 62. A rubber pad 63 is fixedly connected to the opposite side of the clamping plate 62. The rubber pad 63 is set to increase the friction between the clamping plate 62 and the mining machinery parts, and at the same time, it can protect the surface of the parts and prevent damage caused by excessive clamping.

[0038] The base 1 has a movable structure 7 at its bottom. The movable structure 7 includes support columns 71 fixedly connected to the four corners of the bottom of the base 1. A hydraulic push rod 72 is fixedly installed on the top of the inner wall of the support column 71. The hydraulic push rod 72 is connected to an external hydraulic system. Since the hydraulic system is common knowledge in the field and is not an improvement point of this case, it will not be described in detail here. A movable plate 73 is fixedly installed at the bottom of the output end of the hydraulic push rod 72. A shock-absorbing caster 74 is fixedly installed at the bottom of the movable plate 73. The shock-absorbing caster 74 is prior art and will not be described here. To elaborate further, limit grooves 75 are provided at the lower part of both ends of the inner wall of the support column 71, and limit blocks 76 are fixedly connected to both ends of the movable plate 73. The limit blocks 76 are slidably connected in the limit grooves 75. The setting of the limit grooves 75 and the limit blocks 76 facilitates the limiting and guiding of the movement of the movable plate 73. The shock-absorbing casters 74 facilitate the movement of the device. When movement is not required, the movable plate 73 is moved upward by activating the hydraulic push rod 72, which in turn causes the shock-absorbing casters 74 to retract into the support column 71, and the device is supported on the ground by the support column 71, thereby stabilizing the device.

[0039] In practical implementation, this utility model is used by first placing the mining machinery parts onto the placement tray 3. Then, the hydraulic push rod 61 is activated to move the clamping plates 62 closer together, thereby clamping and fixing both ends of the parts. Next, the motor 41 is activated to drive the rotating shaft 42 to rotate, which in turn drives the placement tray 3 to rotate, thus adjusting the placement angle of the mining machinery parts placed on top of the placement tray 3. Then, the hydraulic push rod 51 is activated to move the upright plate 52 upward, which in turn moves the clamping plates 62 and the clamped parts upward. Then, the motor 53 is activated to drive the rotating shaft 54 ​​to rotate, which in turn drives the mounting plate 55 to rotate, thereby causing the clamping plates 62 and the clamped parts to flip over. This allows the parts placed on the placement tray 3 to rotate, facilitating processing on opposite or adjacent sides of the parts without the need for manual rotation. This makes the processing of mining machinery parts simpler and improves the processing efficiency, resulting in good practicality.

[0040] All electrical components mentioned in this document are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. The specific implementation of this disclosure omits detailed descriptions of known functions and components. To ensure device compatibility, the operating methods used are consistent with the parameters of commercially available devices. In addition, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
