Description

Technical Field

[0001] The present invention relates to the technical field of weight plates, and particularly relates to a device and method for removing burrs on the outer peripheral surface of a weight plate. Background Art

[0002] A barbell is a core training sports training equipment and also the equipment used in weightlifting. Barbell exercises belong to a type of weight training. One can use barbell training equipment to enhance muscle strength training or conduct core training using a barbell to promote overall coordination. A weight plate is a core component of a barbell and is used for weighting the barbell. There are many shapes of weight plates, such as circular, square, irregular, etc.

[0003] Weight plates are generally processed by casting, and burrs may be generated during the casting of weight plates.

[0004] In the prior art, the Chinese utility model patent with the publication number CN214519276U discloses a burr cleaning device for casting processing, including a frame, a placement structure, a burr cleaning structure, and a driving structure. The frame is in a frame shape, and a placement structure and a burr cleaning structure are installed inside it. The placement structure and the burr cleaning structure are distributed in the upper and lower parts inside the frame. The placement structure includes a placement plate and a first rotating rod. The placement plate is arc-shaped, and its bottom end is connected to the first rotating rod. A first belt pulley is sleeved on the first rotating rod, and the bottom end of the first rotating rod is movably connected to the bottom wall of the frame through a rotating shaft. The burr cleaning structure includes a housing, a slide rail, a gear, a cleaning swing rod, and a toothed plate. The housing is fixed on the top wall of the frame, and long grooves are provided at the bottom and side of the housing. A slide rail is fixed on the inner top wall of the housing, a spring is provided inside the slide rail, and a toothed plate is slidably connected on the slide rail. This utility model enables the burr cleaning structure to evenly polish the casting, achieving the effects of high polishing efficiency and good polishing effect.

[0005] However, during the process of removing burrs on the outer peripheral surface of the weight plate by this burr removal device, the following defects often exist:

[0006] 1. During the process of removing burrs on the outer peripheral surface of the weight plate, debris is easily generated, causing the debris to splash everywhere, endangering the physical health of the operator, and the operation safety is low;

[0007] 2. During the process of removing burrs on the outer peripheral surface of the weight plate, the burr removal device can only perform burr removal operations on a single end face of the outer peripheral surface of the weight plate, and it cannot perform burr removal operations on both end faces of the outer peripheral surface of the weight plate at the same time. Its burr removal speed is slow, resulting in low burr removal efficiency;

[0008] 3. During the process of removing burrs on the outer peripheral surface of the weight plate, since the weight plate cannot be quickly and effectively fixed, the weight plate is prone to sliding during the burr removal process, resulting in the interruption of the burr removal work of the weight plate and unable to fully ensure the smooth progress of the burr removal work of the weight plate.

[0014] Further, the bidirectional burr removal mechanism further includes a traction push-pull slider, a traction push-pull connecting rod and an end face burr removal component. The first transmission lead screw and the second transmission lead screw are both threadedly connected with a traction push-pull slider. A traction push-pull connecting rod is installed on the traction push-pull slider. One end of the traction push-pull connecting rod passes through the fixed support base and is connected with an end face burr removal component.

[0015] Further, the end face burr removal assembly is located on both sides of the bell piece. The end face burr removal assembly is driven by a bidirectional traction motor to rotate the first transmission screw rod and the second transmission screw rod to move towards or away from each other, and the end face burr removal assembly is pressed against the outer peripheral surface of the bell piece to remove the burrs on the outer peripheral surface of the bell piece.

[0016] Further, the end face burr removal assembly includes a support outer frame, a traction drive screw rod, a drive motor, a moving slide seat and a traction bracket. The support outer frame is connected to the traction push-pull link rod. A traction drive screw rod is arranged inside the support outer frame. The traction drive screw rod is installed on the support outer frame through a bearing and the traction drive screw rod is driven to rotate by the drive motor. The drive motor is installed on the top of the support outer frame. The traction drive screw rod is threadedly connected with the moving slide seat. The moving slide seat passes through the support outer frame and the moving slide seat is connected with the traction bracket.

[0017] Further, a guiding passage groove for the vertical movement of the moving slide seat is formed in the side end face of the support outer frame. The moving slide seat is adapted to the guiding passage groove. The moving slide seat moves in the guiding passage groove by the drive motor driving the traction drive screw rod to rotate.

[0018] Further, the end face burr removal assembly further includes a rotating motor, a rotating shaft and a burr removal grinding head. The burr removal grinding head is installed on the rotating shaft. The rotating shaft is installed on the traction bracket through a bearing and the rotating shaft is driven to rotate by the rotating motor. The rotating motor is installed on the side end face of the traction bracket. The burr removal grinding head rotates tightly against the outer peripheral surface of the bell piece by the rotating motor driving the rotating shaft to rotate and grinds the burrs on the outer peripheral surface of the bell piece;

[0019] The burr removal grinding head includes an outer shield, a linkage support, an electric push rod, a support base, a buffer spring, a linkage push rod and a burr remover. The outer shield is located around the rotating shaft. A linkage support is installed on the rotating shaft. An electric push rod is installed on the linkage support.

[0021] Further, a protective pad is provided on the end face clamping substrate, and the end face clamping substrate is clamped on the end face of the bell plate by driving the inner threaded rod to rotate.

[0022] According to another aspect of the present invention, a cleaning method for a burr removing device on the outer peripheral surface of a bell plate is provided, including the following steps:

[0023] S1: Place the bell plate on the end face clamping base, drive the inner threaded rod to rotate. Since the inner threaded rod is threadedly connected to the outer connecting seat and the outer connecting seat is fixed on the end face clamping base, during the rotation of the inner threaded rod, the inner threaded rod moves horizontally, causing the end face clamping substrate to also move horizontally, until the bell plate is firmly fixed on the end face clamping base;

[0024] S2: Start the bidirectional traction motor and drive the first transmission lead screw and the second transmission lead screw to rotate, causing the traction push-pull slider, the traction push-pull link, and the end face burr removing assembly to be tractionally moved accordingly, until the end face burr removing assembly closely adheres to the outer peripheral surface of the bell plate;

[0025] S3: Start the rotation motor and drive the rotating shaft and the burr removing grinding head to rotate, causing the burr removing grinding head to grind the burrs on the outer peripheral surface of the bell plate, and drive the motor to drive the traction drive lead screw to rotate, causing the moving slide seat, the traction bracket, and the burr removing grinding head to move vertically accordingly. The burrs on the outer peripheral surface of the bell plate are ground and removed bidirectionally by the vertically moving and rotating burr removing grinding head;

[0026] S4: During the process of removing the burrs on the outer peripheral surface of the bell plate, start the dust suction fan, suck the debris generated during the burr removing process through the dust suction outer cover, and collect it through the dust collection bag.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. For the burr removing device and method for the outer peripheral surface of the bell plate of the present invention, in the prior art, during the process of removing the burrs on the outer peripheral surface of the bell plate by the burr removing device, debris is easily generated, causing the debris to splash everywhere, endangering the physical health of the operators, and the operation safety is low. However, on the surface of the processing table of the present invention, a bidirectional burr removing mechanism is provided, and a debris collection and protection mechanism is also provided on the bidirectional burr removing mechanism. The debris collection and protection mechanism includes a dust suction fan, a dust collection bag, a dust suction connecting pipe, and a dust suction outer cover. During the process of removing the burrs on the outer peripheral surface of the bell plate, the dust suction fan is started, the debris generated during the burr removing process is sucked through the dust suction outer cover, and collected through the dust collection bag. The debris collection and protection mechanism can effectively collect the debris generated during the burr removing process, avoid the debris from splashing everywhere and endangering the physical health of the operators, protect the operators, and improve the operation safety;

[0029] 2. The burr removal device and method for the outer peripheral surface of the bell piece of the present invention. In the prior art, the burr removal operation cannot be carried out on the two-way end faces of the outer peripheral surface of the bell piece at the same time, and the burr removal speed is slow, resulting in low burr removal efficiency. The two-way burr removal mechanism of the present invention includes a fixed support base, a two-way traction motor, a first transmission screw rod, a second transmission screw rod, a traction push-pull slider, a traction push-pull connecting rod and an end face burr removal component. The end face burr removal component includes a support outer frame, a traction drive screw rod, a drive motor, a moving slide base, a traction bracket, a rotating motor, a rotating shaft and a burr removal grinding head. The two-way burr removal mechanism can carry out the burr removal operation on the two-way end faces of the outer peripheral surface of the bell piece at the same time, with a fast burr removal speed, improving the burr removal efficiency. Moreover, the two-way burr removal mechanism can carry out the burr removal operation on the two-way end faces of bell pieces of different sizes, with a wide application range and can meet the burr removal requirements in different situations;

[0030] 3. The burr removal device and method for the outer peripheral surface of the bell piece of the present invention. In the prior art, since the bell piece cannot be fixed quickly and effectively, the bell piece is prone to slide during the burr removal process, resulting in the interruption of the burr removal work of the bell piece and unable to fully ensure the smooth progress of the burr removal work of the bell piece. The bell piece of the present invention is fixed on the two-way burr removal mechanism through an end face clamping mechanism. The end face clamping mechanism includes an end face clamping base, an outer connecting seat, an inner threaded rod and an end face clamping substrate. Place the bell piece on the end face clamping base and drive the inner threaded rod to rotate. Since the inner threaded rod is threadedly connected to the outer connecting seat and the outer connecting seat is fixed on the end face clamping base, during the rotation of the inner threaded rod, the inner threaded rod moves horizontally, causing the end face clamping substrate to also move horizontally until the bell piece is firmly fixed on the end face clamping base. The end face clamping mechanism can firmly fix the bell piece and prevent it from sliding easily, and can fully ensure the smooth progress of the burr removal work of the bell piece.

[0031] 4. The burr removal device and method for the outer peripheral surface of the bell piece of the present invention. In the prior art, the burr remover is mostly exposed on the outside, and its surface is prone to accumulate dust, which affects the removal of burrs on the surface of the bell piece. The burr removal grinding head of the present invention includes an outer shield, a linkage support, an electric push rod, a support support, a buffer spring, a linkage push rod and a burr remover. When using the burr removal grinding head to carry out the burr removal operation on the two-way end faces of the bell piece, the electric push rod is started and pushes the support support, the buffer spring, the linkage push rod and the burr remover to move, so that the burr remover extends out of the outer shield. The rotating motor drives the rotating shaft to rotate, and the rotation of the rotating shaft can drive the linkage support and the burr remover to rotate reciprocally, thereby carrying out the burr removal operation on the two-way end faces of the bell piece. After the burrs on the bell piece are removed, the electric push rod is started and pushes the support support, the buffer spring, the linkage push rod and the burr remover to move, so that the burr remover is retracted into the outer shield, avoiding dust accumulation on the burr remover and affecting the removal of burrs on the surface of the bell piece.

Detailed implementation mode

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Refer to Figures 1 - 2 , a burr removal device for the outer peripheral surface of a bell plate, including a processing table 1. Universal wheels 2 are installed at the bottom of the processing table 1, and the universal wheels 2 are distributed at the four corners of the bottom of the processing table 1. A two-way burr removal mechanism 3 is arranged on the surface of the processing table 1. The two-way burr removal mechanism 3 is used to remove the burrs on the outer peripheral surface of the bell plate, and the bell plate is fixed on the two-way burr removal mechanism 3 through an end face clamping mechanism 4. A debris collection and protection mechanism 5 is also arranged on the two-way burr removal mechanism 3. The debris collection and protection mechanism 5 is used to collect the debris generated during the burr removal process.

[0048] Refer to Figures 3 - 4, the bidirectional burr removal mechanism 3 includes a fixed support base 31, a bidirectional traction motor 32, a first transmission screw rod 33 and a second transmission screw rod 34. The fixed support base 31 is installed on the surface of the processing table 1. A bidirectional traction motor 32 is arranged inside the fixed support base 31. The output shaft of the bidirectional traction motor 32 is connected with the first transmission screw rod 33 and the second transmission screw rod 34 through a coupling. The first transmission screw rod 33 and the second transmission screw rod 34 are installed on the inner wall of the fixed support base 31 through bearings. The bidirectional burr removal mechanism 3 further includes a traction push-pull slider 35, a traction push-pull connecting rod 36 and an end face burr removal component 37. The first transmission screw rod 33 and the second transmission screw rod 34 are both threadedly connected with the traction push-pull slider 35. A traction push-pull connecting rod 36 is installed on the traction push-pull slider 35. One end of the traction push-pull connecting rod 36 passes through the fixed support base 31 and is connected with the end face burr removal component 37. The end face burr removal component 37 is located on both sides of the bell piece. The end face burr removal component 37 moves towards or away from each other by driving the first transmission screw rod 33 and the second transmission screw rod 34 to rotate by the bidirectional traction motor 32, and makes the end face burr removal component 37 closely adhere to the outer peripheral surface of the bell piece, so as to remove the burrs on the outer peripheral surface of the bell piece.

[0049] The bidirectional traction motor 32 is started and drives the first transmission screw rod 33 and the second transmission screw rod 34 to rotate, so that the traction push-pull slider 35, the traction push-pull connecting rod 36 and the end face burr removal component 37 are driven to move accordingly until the end face burr removal component 37 closely adheres to the outer peripheral surface of the bell piece, which is convenient for the end face burr removal component 37 to perform burr removal operation on the outer peripheral surface of the bell piece.

[0050] Refer to Figure 5 and Figure 7, the end face burr removal assembly 37 includes a support outer frame 371, a traction drive screw 372, a drive motor 373, a moving slide 374 and a traction bracket 375. The support outer frame 371 is connected to the traction push-pull link 36. Inside the support outer frame 371, there is a traction drive screw 372. The traction drive screw 372 is installed on the support outer frame 371 through bearings and is driven to rotate by the drive motor 373. The drive motor 373 is installed on the top of the support outer frame 371. The traction drive screw 372 is threadedly connected to the moving slide 374. The moving slide 374 passes through the support outer frame 371 and the moving slide 374 is connected to a traction bracket 375. A guiding passage groove 3711 for the vertical movement of the moving slide 374 is provided on the side end face of the support outer frame 371. The moving slide 374 is adapted to the guiding passage groove 3711. The moving slide 374 moves in the guiding passage groove 3711 by driving the traction drive screw 372 to rotate by the drive motor 373. The end face burr removal assembly 37 further includes a rotary motor 376, a rotary shaft 377 and a burr removal grinding head 378. The burr removal grinding head 378 is installed on the rotary shaft 377. The rotary shaft 377 is installed on the traction bracket 375 through bearings and is driven to rotate by the rotary motor 376. The rotary motor 376 is installed on the side end face of the traction bracket 375. The burr removal grinding head 378 rotates closely against the outer peripheral surface of the bell piece by driving the rotary shaft 377 to rotate by the rotary motor 376 and grinds the burrs on the outer peripheral surface of the bell piece.

[0051] The rotary motor 376 starts and drives the rotary shaft 377 and the burr removal grinding head 378 to rotate, so that the burr removal grinding head 378 grinds the burrs on the outer peripheral surface of the bell piece, and the drive motor 373 drives the traction drive screw 372 to rotate, so that the moving slide 374, the traction bracket 375 and the burr removal grinding head 378 move vertically accordingly. The burrs on the outer peripheral surface of the bell piece are ground and removed bidirectionally by the vertically moving and rotating burr removal grinding head 378. The bidirectional burr removal mechanism 3 can simultaneously perform burr removal operations on the two-way end faces of the outer peripheral surface of the bell piece. Its burr removal speed is fast, improving the burr removal efficiency. And the bidirectional burr removal mechanism 3 can perform burr removal operations on the two-way end faces of bell pieces of different sizes. Its application range is wide and it can meet the burr removal requirements in different situations.

[0052] Refer to Figure 6 , the debris collection and protection mechanism 5 includes a dust suction fan 51, a dust collection bag 52, a dust suction connecting pipe 53 and a dust suction outer cover 54. The dust suction fan 51 is installed on the bidirectional burr removal mechanism 3. The air inlet of the dust suction fan 51 is connected to a dust suction connecting pipe 53. The end of the dust suction connecting pipe 53 is threadedly connected to a dust suction outer cover 54. The dust suction outer cover 54 faces the outer peripheral surface of the bell piece. The air outlet of the dust suction fan 51 is connected to a dust collection bag 52. The dust collection bag 52 is used to collect the debris generated during the burr removal process.

[0053] During the process of removing burrs on the outer peripheral surface of the weight plate, the dust suction fan 51 is started, and the debris generated during the burr removal process is sucked in through the dust suction cover 54 and collected by the dust collection bag 52. The debris collection and protection mechanism 5 can effectively collect the debris generated during the burr removal process, avoid the splashing of debris and endanger the physical health of the operator, protect the operator, and improve the operation safety.

[0054] Refer to Figures 8 - 12 , the burr removal grinding head 378 includes an outer shield 3781, a linkage support 3782, an electric push rod 3783, a support support 3784, a buffer spring 3785, a linkage push rod 3786 and a burr remover 3787. The outer shield 3781 is located around the rotating shaft 377. A linkage support 3782 is installed on the rotating shaft 377, and an electric push rod 3783 is installed on the linkage support 3782. The electric push rod 3783 is connected to a support support 3784. A linkage push rod 3786 is arranged inside the support support 3784. The linkage push rod 3786 is connected inside the support support 3784 through a buffer spring 3785. The linkage push rod 3786 is also connected to a burr remover 3787. The burr remover 3787 is located inside the outer shield 3781 and the burr remover 3787 can extend into or out of the outer shield 3781.

[0055] When using the burr removal grinding head 378 to remove burrs on both end faces of the weight plate, the electric push rod 3783 is started and pushes the support support 3784, the buffer spring 3785, the linkage push rod 3786 and the burr remover 3787 to move, so that the burr remover 3787 extends out of the outer shield 3781. The rotation motor 376 is started and drives the rotating shaft 377 to rotate. The rotation of the rotating shaft 377 can drive the linkage support 3782 and the burr remover 3787 to rotate reciprocally, thereby removing burrs on both end faces of the weight plate. After the burrs on the weight plate are removed, the electric push rod 3783 is started and pushes the support support 3784, the buffer spring 3785, the linkage push rod 3786 and the burr remover 3787 to move, so that the burr remover 3787 retracts into the outer shield 3781 to avoid dust accumulation on the burr remover 3787 and affect the removal of burrs on the surface of the weight plate.

[0056] Refer to Figure 13, the end - face clamping mechanism 4 includes an end - face clamping base 41, an outer connecting seat 42, an inner threaded rod 43 and an end - face clamping substrate 44. The end - face clamping base 41 is installed parallel to the fixed support base 31. An outer connecting seat 42 is provided on the end - face clamping base 41. The outer connecting seat 42 is threadedly connected with an inner threaded rod 43. An end - face clamping substrate 44 is installed on the inner threaded rod 43. The end - face clamping substrate 44 is located inside the end - face clamping base 41. A protective pad 6 is provided on the end - face clamping substrate 44. The end - face clamping substrate 44 clamps on the end - face of the bell plate by driving the inner threaded rod 43 to rotate.

[0057] Place the bell plate on the end - face clamping base 41 and drive the inner threaded rod 43 to rotate. Since the inner threaded rod 43 is threadedly connected with the outer connecting seat 42 and the outer connecting seat 42 is fixed on the end - face clamping base 41, during the rotation of the inner threaded rod 43, the inner threaded rod 43 moves horizontally, causing the end - face clamping substrate 44 to move horizontally as well, until the bell plate is firmly fixed on the end - face clamping base 41. Using the end - face clamping mechanism 4, the bell plate can be fixed firmly and is not prone to sliding, which can fully ensure the smooth progress of the burr - removing work on the bell plate.

[0058] In order to better demonstrate the burr - removing process of the burr - removing device for the outer peripheral surface of the bell plate, this embodiment now proposes a burr - removing method for the burr - removing device for the outer peripheral surface of the bell plate, including the following steps:

[0059] S1: Place the bell plate on the end - face clamping base 41 and drive the inner threaded rod 43 to rotate. Since the inner threaded rod 43 is threadedly connected with the outer connecting seat 42 and the outer connecting seat 42 is fixed on the end - face clamping base 41, during the rotation of the inner threaded rod 43, the inner threaded rod 43 moves horizontally, causing the end - face clamping substrate 44 to move horizontally as well, until the bell plate is firmly fixed on the end - face clamping base 41;

[0060] S2: Start the bidirectional traction motor 32 and drive the first transmission lead screw 33 and the second transmission lead screw 34 to rotate, causing the traction push - pull slider 35, the traction push - pull link 36 and the end - face burr - removing assembly 37 to move by traction until the end - face burr - removing assembly 37 is close to the outer peripheral surface of the bell plate;

[0061] S3: Start the rotation motor 376 and drive the rotation shaft 377 and the burr - removing grinding head 378 to rotate, causing the burr - removing grinding head 378 to grind the burrs on the outer peripheral surface of the bell plate. And drive the motor 373 to drive the traction drive lead screw 372 to rotate, causing the moving slide 374, the traction bracket 375 and the burr - removing grinding head 378 to move vertically. The burrs on the outer peripheral surface of the bell plate are ground and removed bidirectionally by the vertically moving and rotating burr - removing grinding head 378;

[0062] S4: During the process of removing burrs from the outer peripheral surface of the weight plate, the dust suction fan 51 is started, and the debris generated during the burr removal process is sucked in through the dust suction cover 54 and collected by the dust collection bag 52.

[0063] In summary, for the burr removal device and method for the outer peripheral surface of the weight plate of the present invention, the weight plate is placed on the end surface clamping base 41, and the inner threaded rod 43 is driven to rotate. Since the inner threaded rod 43 is threadedly connected to the outer connection seat 42 and the outer connection seat 42 is fixed to the end surface clamping base 41, during the rotation of the inner threaded rod 43, the inner threaded rod 43 moves horizontally, causing the end surface clamping substrate 44 to also move horizontally, until the weight plate is firmly fixed on the end surface clamping base 41. The end surface clamping mechanism 4 can firmly fix the weight plate and prevent it from sliding, fully ensuring the smooth progress of the burr removal work for the weight plate. The bidirectional traction motor 32 is started and drives the first transmission lead screw 33 and the second transmission lead screw 34 to rotate, causing the traction push-pull slider 35, the traction push-pull link 36, and the end surface burr removal assembly 37 to be tractionally moved accordingly, until the end surface burr removal assembly 37 is closely attached to the outer peripheral surface of the weight plate. The rotation motor 376 is started and drives the rotation shaft 377 and the burr removal grinding head 378 to rotate, causing the burr removal grinding head 378 to grind the burrs on the outer peripheral surface of the weight plate. The drive motor 373 drives the traction drive lead screw 372 to rotate, causing the moving slide base 374, the traction bracket 375, and the burr removal grinding head 378 to move vertically accordingly. The burrs on the outer peripheral surface of the weight plate are removed by the vertically moving and rotating burr removal grinding head 378 through two-way grinding. The two-way burr removal mechanism 3 can simultaneously perform burr removal operations on the two end surfaces of the outer peripheral surface of the weight plate. The burr removal speed is fast, improving the burr removal efficiency. The two-way burr removal mechanism 3 can perform burr removal operations on the two end surfaces of the outer peripheral surface of weight plates of different sizes, with a wide range of applications and can meet the burr removal requirements in different situations. During the process of removing burrs from the outer peripheral surface of the weight plate, the dust suction fan 51 is started, and the debris generated during the burr removal process is sucked in through the dust suction cover 54 and collected by the dust collection bag 52. The debris collection and protection mechanism 5 can effectively collect the debris generated during the burr removal process, prevent the debris from splashing everywhere and endangering the physical health of the operators, protect the operators, and improve the operation safety.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
