Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of positioning sleeves for shot blasting machines, and in particular to a positioning sleeve for shot blasting machines. Background Technology
[0002] A shot blasting machine is a device that uses a high-speed stream of shot thrown by a shot blaster to clean, strengthen, or shape the surface of a workpiece. The positioning sleeve is a key connecting component in the pipeline system of the shot blasting machine. It is used to ensure reliable sealing at the interface, prevent steel shot leakage, and ensure the stability of the position of the external pipeline.
[0003] Existing technologies, such as the utility model with publication number CN208068049U, disclose a shot blasting device. This patent includes a shell, a directional sleeve, a shot distribution wheel, a motor, a main shaft, and an impeller. This utility model has excellent wear resistance and mechanical strength. The arc-shaped design of the shot blasting hole ensures that the shot is ejected from the middle position of the shot blasting hole. The first and second reinforcing ribs improve the structural strength of the shot blasting wall and prevent the shot from damaging the shot wall. The third reinforcing rib and triangular rib improve the mechanical strength of the weakest part of the shot blasting wall, which helps to extend the service life of the shot distribution wheel. The rubber layer set in the arc-shaped groove and the shot blasting hole helps to reduce the impact caused by the shot. The retaining ring, plug, and positioning block at the upper end of the mounting plate ensure a tight connection between the shot distribution wheel and the directional sleeve, preventing loosening and thus ensuring shot distribution efficiency.
[0004] The inventors encountered the following problems when using the positioning sleeve: Traditional connection methods often use multiple bolts to directly tighten the flange or pipe clamp. When it is necessary to replace the sealing ring or the positioning sleeve itself that has failed due to long-term wear, the operator must use tools to disassemble the bolts one by one. The process is cumbersome, time-consuming and labor-intensive, which seriously affects the efficiency of equipment maintenance. Utility Model Content
[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as cumbersome disassembly and assembly operations, which are time-consuming and labor-intensive.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning sleeve for a shot blasting machine, comprising a machine body, a docking groove provided on one side of the machine body, a positioning tube installed on the inner wall of the docking groove, a sealing ring abutting the side of the positioning tube away from the machine body, and an outer connecting pipe abutting the side of the sealing ring away from the positioning tube. An adjustment structure is provided on the side of the machine body near the positioning tube, the adjustment structure including a fixing frame, the fixing frame being fixedly connected to the machine body, a support frame being rotatably connected to the arc surface of the fixing frame, an adjusting rod being threadedly connected to the surface of the support frame, and a clamping plate being rotatably connected to the end of the adjusting rod near the machine body. Two round rods are fixedly connected to the side. The arc surfaces of the two round rods are slidably connected to the support frame. A connecting block is fixedly connected to the end of the support frame away from the fixed frame. A limit frame is fixedly connected to the side of the machine body near the fixed frame, corresponding to the position of the connecting block. The inner wall of the limit frame is slidably connected to the connecting block. A limit rod is slidably connected to the inner wall of the limit frame.

A slide rod is fixedly connected to the lower surface of the handle. The arc surface of the slide rod is slidably connected to the limit frame. A spring is sleeved on the arc surface of the slide rod. The two ends of the spring are fixedly connected to the limit frame and the slide rod, respectively.
[0007] The aforementioned components achieve the following effects: they enable quick clamping, fixing, and releasing of the outer pipe of the shot blasting machine, facilitating the maintenance and replacement of the positioning pipe and sealing ring, and improving the maintainability and ease of operation of the equipment.
[0008] Preferably, the end of the adjusting rod away from the clamp is slidably connected to a handle, which is a steel rod.
[0009] The effect achieved by the above components is that the added lever increases the lever arm of the adjusting rod, making it easier to turn the adjusting rod and operate it more easily.
[0010] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the side of the clamp away from the adjusting rod.
[0011] The effect achieved by the above components is that the anti-slip pad increases the friction between the clamp and the outer pipe, preventing the outer pipe from sliding or loosening during the fixing process, and improving the stability and sealing of the connection.
[0012] Preferably, a support plate is fixedly connected to the lower surface of the support frame at the position corresponding to the outer pipe, and the upper surface of the support plate is curved.
[0013] The effect achieved by the above components is as follows: the support plate is used to support the outer pipe, and its curved design fits the outer wall of the outer pipe, playing a role in auxiliary support and positioning, reducing the burden on the clamp plate, and making the connection more centered and stable.
[0014] Preferably, the arc surface of the slide rod is fitted with a corrugated tube, and the two ends of the corrugated tube are fixedly connected to the limiting frame and the slide rod, respectively.
[0015] The effect achieved by the above components is that the bellows encloses the slide rod and spring, which can effectively prevent dust, debris and other foreign objects from entering the limit frame, avoid the mechanism from jamming, and extend the service life of the spring and sliding components.
[0016] Preferably, the lower end of the limiting rod is arc-shaped, and the limiting rod is specifically a stainless steel rod.
[0017] The effects achieved by the above components are as follows: the arc-shaped lower end makes it easier for the limiting rod to be guided and positioned when it is engaged with the connecting block; the use of stainless steel ensures that the limiting rod has sufficient strength and corrosion resistance, and is suitable for the working environment of the shot blasting machine.
[0018] In summary, the beneficial effects of this utility model are as follows:
[0019] In this invention, an adjustable structure is incorporated, and a threaded clamping plate provides stable clamping force. Combined with a reversible support frame design, this allows operators to easily maintain and replace the positioning sleeve and sealing ring without the need for special tools.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0026] Reference Figure 1 As shown, this utility model provides a technical solution: a positioning sleeve for a shot blasting machine, including a machine body 1, a docking groove 2 is provided on one side of the machine body 1, a positioning tube 3 is installed on the inner wall of the docking groove 2, a sealing ring 4 is abutted on the side of the positioning tube 3 away from the machine body 1, an outer tube 5 is abutted on the side of the sealing ring 4 away from the positioning tube 3, and an adjustment structure 6 is provided on the side of the machine body 1 close to the positioning tube 3.
[0027] The specific settings and functions of its adjustment structure 6 will be explained in detail below.
[0028] Reference Figures 2 to 4As shown in this embodiment: the adjustment structure 6 includes a fixed frame 601, which is fixedly connected to the body 1. A support frame 602 is rotatably connected to the arc surface of the fixed frame 601. An adjustment rod 603 is threadedly connected to the surface of the support frame 602. A clamping plate 604 is rotatably connected to the end of the adjustment rod 603 near the body 1. Two round rods 605 are fixedly connected to the side of the clamping plate 604 near the support frame 602. The arc surfaces of the two round rods 605 are slidably connected to the support frame 602. A connecting block 609 is fixedly connected to the end of the support frame 602 away from the fixed frame 601. A limit frame 610 is fixedly connected to the side of the body 1 near the fixed frame 601 at the position corresponding to the connecting block 609. The inner wall of the limit frame 610 is connected to the connecting block 609. 9. A sliding connection is made, with a limiting rod 611 slidably connected to the inner wall of the limiting frame 610. The arc surface of the limiting rod 611 engages with the connecting block 609. A handle 612 is fixedly connected to the upper end of the limiting rod 611, and a sliding rod 613 is fixedly connected to the lower surface of the handle 612. The arc surface of the sliding rod 613 is slidably connected to the limiting frame 610. A spring 614 is fitted onto the arc surface of the sliding rod 613, and both ends of the spring 614 are fixedly connected to the limiting frame 610 and the sliding rod 613, respectively. This allows for quick clamping, fixing, and releasing of the outer pipe 5 of the shot blasting machine, facilitating the maintenance and replacement of the positioning tube 3 and the sealing ring 4, thus improving the maintainability and ease of operation of the equipment. A handle 606 is slidably connected to the end of the adjusting rod 603 away from the clamping plate 604. The rod 606 is a steel rod. The addition of the handle 606 increases the lever arm of the adjusting rod 603, making it easier and less strenuous to rotate. An anti-slip pad 607 is fixedly connected to the side of the clamping plate 604 away from the adjusting rod 603. The anti-slip pad 607 is a rubber pad, which increases the friction between the clamping plate 604 and the outer connecting pipe 5, preventing the outer connecting pipe 5 from sliding or loosening during fixing, thus improving the stability and sealing of the connection. A support plate 608 is fixedly connected to the lower surface of the support frame 602 at the position corresponding to the outer connecting pipe 5. The upper surface of the support plate 608 is curved, and it supports the outer connecting pipe 5. Its curved design fits snugly against the outer wall of the outer connecting pipe 5, providing auxiliary support and positioning, and reducing the strain on the clamping plate. The load on plate 604 makes the connection more aligned and stable. The arc surface of slide rod 613 is fitted with a bellows 615. The two ends of the bellows 615 are fixedly connected to the limiting frame 610 and slide rod 613 respectively. The bellows 615 encloses slide rod 613 and spring 614, which can effectively prevent dust, debris and other foreign objects from entering the interior of limiting frame 610, avoid mechanism jamming, and extend the service life of spring 614 and sliding parts. The lower end of limiting rod 611 is arc-shaped. The limiting rod 611 is made of stainless steel. The arc-shaped lower end makes it easier for limiting rod 611 to be guided and positioned when it is snapped into connecting block 609. The use of stainless steel material ensures that limiting rod 611 has sufficient strength and corrosion resistance, and is suitable for the working environment of shot blasting machine.
[0029] Detailed Instructions for Use: By setting the adjustment structure 6, first rotate the adjustment rod 603. The adjustment rod 603 moves along the support frame 602 away from the machine body 1 via the thread. The adjustment rod 603 drives the clamping plate 604 to move. During this process, the round rod 605 always moves along the support frame 602. The clamping plate 604 no longer presses against the outer connecting pipe 5, releasing the limit on the outer connecting pipe 5. Then, move the handle 612 upward. The handle 612 drives the limit rod 611 and the sliding rod 613 to move upward. During this process, the limit rod 611 gradually slides away from the connecting block 609, and the spring 614 is in a compressed state. When the limiting rod 611 is fully disengaged from the connecting block 609, the limiting effect on the support frame 602 is released. At this point, the support frame 602 can be opened by rotating along the fixed frame 601. The user can then disassemble and maintain the outer connecting pipe 5, sealing ring 4, and positioning pipe 3 in sequence. After maintenance, the support frame 602 is rotated in the opposite direction to reset it. The connecting block 609 slides into the limiting frame 610. The handle 612 is released, and the compressed spring 614 gives the sliding rod 613 a downward force, causing the handle 612 and the limiting rod 611 to move downward. The limiting rod 611 slides into the connecting block 609, thus positioning the support frame 602. The device is fixed in place, and then the adjusting rod 603 is rotated in the opposite direction. The adjusting rod 603 moves towards the machine body 1 via the thread. The adjusting rod 603 drives the clamping plate 604 to press and fix the outer connecting pipe 5. The handle 606 increases the lever arm of the adjusting rod 603, making it easier to rotate and operate. The anti-slip pad 607 increases the friction between the clamping plate 604 and the outer connecting pipe 5, preventing the outer connecting pipe 5 from sliding or loosening during the fixing process, and improving the stability and sealing of the connection. The support plate 608 is used to support the outer connecting pipe 5, and its curved surface design is consistent with... The outer pipe 5 fits snugly against the outer wall, providing auxiliary support and positioning, reducing the burden on the clamping plate 604, and making the connection more aligned and stable. The corrugated pipe 615 encloses the sliding rod 613 and spring 614, effectively preventing dust, debris and other foreign objects from entering the limit frame 610, avoiding mechanism jamming, and extending the service life of the spring 614 and sliding parts. The arc-shaped lower end makes it easier for the limit rod 611 to be guided and positioned when it is snapped into the connecting block 609. The use of stainless steel ensures that the limit rod 611 has sufficient strength and corrosion resistance, adapting to the working environment of the shot blasting machine.
