Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to a stable clamping mechanism and electroplating equipment. Background Art

[0002] During the electroplating process, some online continuous electroplating equipment needs to transport the parts to be plated along the conveyor line through a conveying device, so that multiple parts to be plated enter the electroplating tank in turn to receive electroplating processing, and then the parts to be plated that have completed the electroplating are removed from the electroplating tank. The parts to be plated are generally clamped and positioned on the transportation equipment by electroplating clamps.

[0003] In the related art, the electroplating clamp generally includes two clamping bodies. Some electroplating clamps use the elastic force of an elastic member to clamp the two clamping bodies against each other, thereby clamping and positioning the workpiece to be plated. Other electroplating clamps are provided with a fixed clamping body and a movable clamping body. When the electroplating clamp moves with the conveying equipment, a track is provided on the conveying line to make the movable clamping body slide relative to the fixed clamping body, thereby realizing the opening and closing of the electroplating clamp, and then clamping or loosening the workpiece to be plated.

[0004] However, when the workpiece to be plated is a workpiece with a narrow clamping portion and a large weight, such as a high aspect ratio plate, or when an ultrasonic wave or a vibrator is installed in the electroplating tank, the above-mentioned two types of electroplating clamps have limited clamping stability on the workpiece to be plated, which can easily cause the workpiece to be plated to fall off the electroplating clamps. Utility Model Content

[0005] In view of this, the utility model provides a stable clamping mechanism and electroplating equipment to solve the problem that the workpiece to be plated is easily dropped from the electroplating clamp when the clamping portion is narrow and the weight is heavy, and when there are ultrasonic waves or vibrators in the electroplating tank.

[0006] In the first aspect, the utility model provides a stable clamping mechanism, including a base frame; a clamping structure, including a first clamping rod and a second clamping rod, the first clamping rod is fixedly connected to the base frame, the second clamping rod is slidably connected to the base frame, the first clamping rod is provided with a first clamping portion at the end away from the base frame, the second clamping rod is provided with a second clamping portion at the end away from the base frame, the first clamping portion and the second clamping portion are arranged opposite to each other, and the second clamping rod slides in the direction in which the second clamping portion approaches or moves away from the first clamping portion; a transmission structure, suitable for driving the second clamping rod to slide, and limiting the second clamping rod at any position during sliding.

[0007] Beneficial effects: The first clamping rod is fixedly connected to the base frame, and the second clamping rod is slidably connected to the base frame. During the sliding process of the second clamping rod, the second clamping part is moved close to or away from the first clamping part, thereby achieving the clamping and loosening of the plated workpiece. By setting a transmission structure to drive the sliding of the second clamping rod, it is convenient for the staff to operate the opening and closing of the clamping structure through the transmission structure. At the same time, since the transmission structure can be limited at any position during the sliding process of the second clamping rod, after the staff clamps the plated workpiece through the transmission structure, the clamping structure is not easy to loosen or fall off. In addition, since the transmission structure can limit the second clamping rod at any position during the sliding process, the clamping structure can clamp the plated workpieces of different thicknesses with the same clamping force, and the clamping structure will not leave a gap between the plated workpiece and the corresponding first clamping part and the second clamping part due to the wear of the first clamping part and the second clamping part due to long-term use, resulting in unstable clamping, so that the clamping of the plated workpiece is more stable and reliable.

[0008] In an optional embodiment, the transmission structure includes a worm wheel, a worm and a gear, the worm wheel and the gear are rotatably connected to the base frame via the same rotating shaft, the worm is meshed with the worm wheel, the second clamping rod is provided with a rack arranged along the sliding direction of the second clamping rod, and the gear is meshed with the rack.

[0009] Beneficial effect: By setting a worm wheel, a worm, a gear and a rack set on the second clamping rod, the staff can rotate the worm wheel by turning the worm. The worm wheel and the gear are coaxially set, so that the gear rotates synchronously, and the gear drives the rack, thereby driving the second clamping rod to make a linear motion, thereby realizing the control of the opening and closing of the clamping structure. At the same time, since the transmission between the turbine and the worm can only be transmitted from the worm end to the worm wheel end, the transmission structure can limit the second clamping rod at any position in the process of the transmission structure driving the second clamping rod to slide, thereby avoiding the situation where the clamping structure loosens and causes the plated workpiece to fall off, and when affected by the vibrator and ultrasonic wave in the electroplating tank, the clamping structure can also maintain stable clamping of the plated workpiece.

[0010] In an optional embodiment, a manual knob is provided at the end of the worm.

[0011] Beneficial effect: By setting a manual knob, it is convenient for the staff to manually rotate the worm to control the opening and closing of the clamping structure.

[0013] Beneficial effect: By setting up a first sliding frame and opening a first sliding groove on the first sliding frame, a sliding portion compatible with the first sliding groove is set on the second clamping rod, thereby realizing the relative sliding of the second clamping rod and the base frame. At the same time, since the number of the first sliding grooves is at least two, at least two first sliding grooves play a guiding and limiting role for the second clamping rod, thereby making the movement direction of the second clamping rod more stable.

[0014] In an optional embodiment, the base frame also includes a second sliding frame, which is arranged opposite to the first sliding frame, and the second sliding frame is provided with at least two second sliding grooves, which are arranged opposite to the first sliding grooves one by one, and the sliding part is located between the first sliding frame and the second sliding frame, and is slidably matched with the corresponding first sliding groove and second sliding groove respectively through pins.

[0015] Beneficial effect: By setting up a second sliding frame and opening a second sliding groove on the second sliding frame, the sliding part on the second clamping rod is slidably matched with the first sliding groove and the second sliding groove respectively through pins, thereby enhancing the sliding limit stability of the second clamping rod and improving the structural strength of the entire clamping mechanism, thereby improving the carrying capacity of the clamping mechanism.

[0016] In an optional embodiment, a reinforcement structure is provided between the first sliding frame and the second sliding frame.

[0017] Beneficial effect: By setting a reinforcing structure between the first sliding frame and the second sliding frame, the position between the first sliding frame and the second sliding frame is supported, thereby further improving the structural strength of the mechanism and preventing the clamping mechanism from being deformed or broken when used for a long time or carrying heavier plated parts.

[0018] In an optional embodiment, the sliding portion abuts against the first sliding frame and the second sliding frame respectively.

[0019] Beneficial effect: Since the two sides of the sliding part are respectively abutted against the first sliding frame and the second sliding frame, the first sliding frame and the second sliding frame can not only provide a carrier for the sliding connection of the second clamping rod, but also limit the second clamping rod along the width direction of the second clamping rod, thereby reducing the deviation and shaking of the second clamping rod, thereby improving the clamping stability.

In the process of clamping the plated workpiece by the clamping structure, the bending moment or torque from the plated workpiece is shared from one of the first clamping rod and the second clamping rod to the other through the guiding structure, thereby improving the overall strength of the clamping structure.

[0022] In an optional embodiment, the first clamping portion and the second clamping portion are both provided with a friction portion suitable for increasing the friction force between the plated object and the plated object, and the two friction portions are arranged opposite to each other.

[0023] Beneficial effect: By providing the friction part, the friction between the first clamping part and the second clamping part and the plated workpiece is improved, the clamping stability is improved, and the possibility of the plated workpiece being detached is reduced.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.

[0034] According to an embodiment of the present invention, on the one hand, a stable clamping mechanism is provided, including a base frame 100; see Figure 1 and Figure 3 The clamping structure 200 includes a first clamping rod 201 and a second clamping rod 202. The first clamping rod 201 is fixedly connected to the base frame 100, and the second clamping rod 202 is slidably connected to the base frame 100. The end of the first clamping rod 201 away from the base frame 100 is provided with a first clamping portion 2011, and the end of the second clamping rod 202 away from the base frame 100 is provided with a second clamping portion 2021. The first clamping portion 2011 and the second clamping portion 2021 are arranged opposite to each other, and the second clamping rod 202 slides in the direction in which the second clamping portion 2021 approaches or moves away from the first clamping portion 2011; the transmission structure 300 is suitable for driving the second clamping rod 202 to slide, and limiting the second clamping rod 202 at any position during sliding.

[0035] In this embodiment, the first clamping rod 201 is fixedly connected to the base frame 100, and the second clamping rod 202 is slidably connected to the base frame 100. During the sliding of the second clamping rod 202, the second clamping portion 2021 is moved closer to or away from the first clamping portion 2011, thereby achieving clamping and loosening of the plated workpiece. By setting a transmission structure 300 to drive the sliding of the second clamping rod 202, it is convenient for the staff to operate the opening and closing of the clamping structure 200 through the transmission structure 300. At the same time, since the transmission structure 300 can be limited at any position during the sliding of the second clamping rod 202, after the staff clamps the plated workpiece with the clamping structure 200 through the transmission structure 300, the clamping structure 200 is not easy to loosen or fall off. In addition, since the transmission structure 300 can limit the second clamping rod 202 at any position during the sliding process, the clamping structure 200 can clamp the plated workpieces of different thicknesses with the same clamping force. Moreover, the clamping structure 200 will not leave a gap between the plated workpiece and the corresponding first clamping part 2011 and second clamping part 2021 due to the wear of the first clamping part 2011 and the second clamping part 2021 due to long-term use, resulting in unstable clamping. Therefore, the clamping of the plated workpiece is more stable and reliable.

[0036] In one embodiment, see Figure 2 The transmission structure 300 includes a worm wheel 301, a worm 302 and a gear 303. The worm wheel 301 and the gear 303 are rotatably connected to the base frame 100 through the same rotating shaft. The worm 302 is meshed with the worm wheel 301. The second clamping rod 202 is provided with a rack 304 arranged along the sliding direction of the second clamping rod 202, and the gear 303 is meshed with the rack 304.

[0037] Specifically, the rack 304 may be integrally provided with the second clamping rod 202 , and in some embodiments not shown, may also be fixedly connected to the side wall of the second clamping rod 202 .

[0038] In this embodiment, by setting a worm wheel 301, a worm 302, a gear 303 and a rack 304 set on the second clamping rod 202, the staff can rotate the worm 302 to rotate the worm wheel 301. The worm wheel 301 and the gear 303 are coaxially set, so that the gear 303 rotates synchronously, and the gear 303 drives the rack 304, thereby driving the second clamping rod 202 to make a linear motion, thereby realizing the control of the opening and closing of the clamping structure 200. At the same time, since the transmission between the turbine and the worm 302 can only be transmitted from the worm 302 end to the worm wheel 301 end, the transmission structure 300 can limit the second clamping rod 202 at any position in the process of the transmission structure 300 driving the second clamping rod 202 to slide, thereby avoiding the situation where the clamping structure 200 loosens and causes the plated workpiece to fall off, and when affected by the vibrator and ultrasound in the electroplating tank, the clamping structure 200 can also maintain a stable clamping of the plated workpiece.

[0039] In addition, it should be noted that the present embodiment does not limit the specific form of the transmission structure 300. It is only required to drive the second clamping rod 202 to slide and to limit the second clamping rod 202 at any position during the sliding process. For example, in some embodiments not shown, the transmission structure 300 may also include a screw rod, which is threadedly matched with the second clamping rod 202 and rotatably matched with the frame, so that the staff can drive the second clamping rod 202 to slide by rotating the screw rod.

[0040] In one embodiment, the base frame 100 includes a first sliding frame 101, the first clamping rod 201 is arranged at the end of the first sliding frame 101, at least two first sliding grooves 1011 are opened on the first sliding frame 101, the length direction of the first sliding groove 1011 is parallel to the sliding direction of the second clamping rod 202, and the second clamping rod 202 is provided with a sliding part 2022 that slides with the first sliding groove 1011.

[0041] In this embodiment, by setting up a first sliding frame 101 and opening a first sliding groove 1011 on the first sliding frame 101, a sliding portion 2022 compatible with the first sliding groove 1011 is set on the second clamping rod 202, thereby realizing the relative sliding of the second clamping rod 202 and the base frame 100. At the same time, since the number of the first sliding grooves 1011 is at least two, at least two first sliding grooves 1011 play a guiding and limiting role for the second clamping rod 202, thereby making the movement direction of the second clamping rod 202 more stable.

[0042] It should be further explained that the present embodiment does not limit the specific sliding connection form between the second clamping rod 202 and the base frame 100. For example, in some embodiments not shown, the second clamping rod 202 and the base frame 100 can be realized by the cooperation of a slider and a slide groove, or by other forms of cooperation.

[0043] In one embodiment, the base frame 100 also includes a second sliding frame 102, which is arranged opposite to the first sliding frame 101. The second sliding frame 102 is provided with at least two second sliding grooves 1021, and the second sliding grooves 1021 are arranged opposite to the first sliding grooves 1011 one by one. The sliding portion 2022 is located between the first sliding frame 101 and the second sliding frame 102, and is slidably matched with the corresponding first sliding grooves 1011 and the second sliding grooves 1021 through pins 2023.

[0044] Specifically, both the first sliding groove 1011 and the second sliding groove 1021 are waist-shaped grooves, and the length direction of the waist-shaped groove is the same as the sliding direction of the second clamping rod 202 .

[0045] In this embodiment, by setting up a second sliding frame 102 and opening a second sliding groove 1021 on the second sliding frame 102, the sliding part 2022 on the second clamping rod 202 is slidably matched with the first sliding groove 1011 and the second sliding groove 1021 respectively through the pin 2023, thereby enhancing the sliding limit stability of the second clamping rod 202 and improving the structural strength of the entire clamping mechanism, thereby improving the carrying capacity of the clamping mechanism.

[0046] In one embodiment, a reinforcement structure 400 is disposed between the first sliding frame 101 and the second sliding frame 102 .

[0047] Specifically, this embodiment does not limit the specific form of the reinforcement structure 400. The reinforcement structure 400 can be a block structure that is arranged between the first sliding frame 101 and the second sliding frame 102 and is fixedly connected to the first sliding frame 101 and the second sliding frame 102 respectively. In some embodiments not shown, the reinforcement structure 400 can also be a reinforcement rib or reinforcement rib that is fixedly connected to the first sliding frame 101 and the second sliding frame 102 respectively.

[0048] In this embodiment, a reinforcing structure 400 is provided between the first sliding frame 101 and the second sliding frame 102 to support the position between the first sliding frame 101 and the second sliding frame 102, thereby further improving the structural strength of the mechanism and preventing the clamping mechanism from being deformed or broken during long-term use or when carrying heavier plated parts.

[0049] In one embodiment, the sliding portion 2022 abuts against the first sliding frame 101 and the second sliding frame 102 respectively.

[0050] In this embodiment, since the two sides of the sliding portion 2022 are respectively abutted against the first sliding frame 101 and the second sliding frame 102, the first sliding frame 101 and the second sliding frame 102 can not only provide a carrier for the sliding connection for the second clamping rod 202, but also limit the second clamping rod 202 along the width direction of the second clamping rod 202, thereby reducing the deviation and shaking of the second clamping rod 202, thereby improving the clamping stability.

[0051] In one embodiment, a guide structure 500 is also included, and the guide structure 500 includes a connecting portion 501 and a limiting frame 502. One of the first clamping rod 201 and the second clamping rod 202 is fixedly connected to the connecting portion 501, and the other is adapted to the inner size of the limiting frame 502 and passes through the limiting frame 502 from the frame.

[0052] In this embodiment, a guide structure 500 is provided, and a connecting portion 501 of the guide structure 500 is fixedly connected to one of the first clamping rod 201 and the second clamping rod 202, and a limit frame 502 is slidably matched with the other one, and the first clamping rod 201 or the second clamping rod 202 is limited by the inner frame contour of the limit frame 502, so that the second clamping rod 202 maintains parallel movement relative to the first clamping rod 201, thereby further enhancing the accuracy and stability of the sliding guide of the second clamping rod 202. In addition, in the process of clamping the plated workpiece by the clamping structure 200, the bending moment or torque from the plated workpiece is shared from one of the first clamping rod 201 and the second clamping rod 202 to the other through the guide structure 500, thereby improving the overall strength of the clamping structure 200.

[0053] In one embodiment, a manual knob 3021 is provided at the end of the worm 302 .

[0054] Specifically, the present embodiment does not set a specific shape of the manual knob 3021 , so that the staff can manually operate the rotating worm 302 to facilitate the operation.

[0055] In this embodiment, a manual knob 3021 is provided to facilitate a worker to manually rotate the worm 302 to control the opening and closing of the clamping structure 200 .

[0056] In one embodiment, the first clamping portion 2011 and the second clamping portion 2021 are both provided with a friction portion 600 suitable for increasing the friction force between the plated object and the plated object, and the two friction portions 600 are arranged opposite to each other.

[0057] Specifically, the friction part 600 may be a friction pad, or may be a rough texture arranged on the first clamping part 2011 or the second clamping part 2021 to increase the friction force.

[0058] In this embodiment, by providing the friction part 600, the friction force between the first clamping part 2011 and the second clamping part 2021 and the plated object is increased, the clamping stability is improved, and the possibility of the plated object being separated is reduced.
