Description

Technical Field

[0001] This utility model relates to the field of workpiece flushing technology, and in particular to a workpiece flushing fixture. Background Technology

[0002] In the process of mechanical manufacturing and parts processing, after workpieces have undergone cutting, grinding, or shaping, their surfaces often retain residues such as oil, chips, and dust. Therefore, effective rinsing and cleaning of workpieces is a crucial step in ensuring the quality of subsequent processes (such as spraying, electroplating, and assembly) or ensuring the final cleanliness of the product.

[0003] Many existing workpiece washing equipment uses fixed nozzles or spray structures that can only move linearly. When dealing with workpieces with complex structures, this washing method is difficult to cover areas such as grooves, blind holes, or inner walls, easily creating blind spots and resulting in incomplete cleaning.

[0004] Furthermore, different rinsing processes may require different rinsing effects. For example, a high-pressure water jet may be used to vigorously rinse a specific area first, followed by a large-scale fan-shaped spray for thorough rinsing. For existing equipment, achieving this switch usually requires operators to stop the equipment and manually change different nozzle sizes or switch different pipelines. This process not only interrupts the automated flow but is also cumbersome, significantly reducing production efficiency and equipment applicability.

[0005] Therefore, this utility model proposes a workpiece rinsing fixture to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the workpiece rinsing fixture, such as dead corners, incomplete cleaning, complex structure, cumbersome operation and low efficiency when switching between different rinsing effects, this utility model aims to provide a workpiece rinsing fixture with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a workpiece rinsing fixture, comprising: a base, a three-axis guide rail mounted on the base, and a rotary clamping mechanism mounted on the base for clamping and rotating the workpiece body; and a multi-specification rinsing mechanism mounted on the three-axis guide rail. The multi-specification rinsing mechanism includes an inner opening block with an inner water guide groove inside; a water pump, which is an external water pump and fixedly connected to the inner opening block via a connecting pipe; an outer opening block, which is sleeved on and rotatably connected to the outer wall of the inner opening block; and multiple nozzles, each nozzle fixedly connected to the outer wall of the outer opening block, with an outer water guide groove inside the outer opening block communicating with each nozzle. Furthermore, the outer opening block is rotatably connected to the inner opening block; by rotating the outer opening block, the opening of any one of the outer water guide grooves is aligned with the opening of the inner water guide groove, thereby connecting different nozzles.

[0008] Preferably, the rotary clamping mechanism includes: a motor; a drive shaft, one end of which is fixedly connected to the output end of the motor; a rotating block, through which the drive shaft passes and is slidably connected; a rotating shell, rotatably connected to a limiting groove formed in the outer wall of the rotating block; two gripper discs, threadedly connected to the rotating shell; and gripper heads, fixed to the gripper discs. This structure drives the workpiece body to rotate via the motor, and adjusts the spacing of the gripper discs by rotating the rotating shell to clamp different workpieces.

[0009] Preferably, a plurality of steel balls are disposed between one side of the rotating block and the inner wall of the base. This arrangement utilizes the rolling friction of the steel balls to reduce the resistance when the rotating block rotates.

[0010] Preferably, the sliding connection between the drive shaft and the rotating block is a spline fit. This spline fit structure ensures that the motor can reliably transmit torque to the rotating block when driving the drive shaft to rotate.

[0011] Preferably, two gripper discs are provided, and the two gripper discs are arranged opposite to each other along the axis of the rotating shell. This relative arrangement facilitates automatic centering when clamping the workpiece body, ensuring clamping stability.

[0012] Preferably, the system also includes a viewing housing, which is fixedly connected to the top of the base, and the three-axis guide rail is mounted inside the viewing housing. The viewing housing provides protection for the internal components and effectively prevents rinsing fluid from splashing outwards.

[0013] Preferably, it also includes a drain trough, which is fixed inside the base and located below the rotating clamping mechanism. The drain trough is used to collect waste liquid generated after rinsing operations for centralized treatment.

[0014] Preferably, the plurality of nozzles have different nozzle specifications. For example, they may include high-pressure DC nozzles, fan-shaped spray nozzles, etc., to meet the rinsing requirements of different processes.

[0015] Preferably, the inner water guide groove has an opening facing the outer opening block, and the outer water guide groove has an opening facing the inner opening block. The outer opening block rotates to align the opening of any of the outer water guide grooves with the opening of the inner water guide groove. This structure is a mechanical rotary valve that achieves water flow and switching through the alignment and misalignment of the openings. It has a simple structure and reliable sealing.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of dead angles and incomplete coverage in the workpiece washing process in the prior art by setting a rotating clamping mechanism to drive the workpiece body to rotate, and at the same time cooperating with a movable multi-specification washing mechanism installed on a three-axis guide rail, thereby achieving the effect of washing the workpiece from multiple angles and in all directions.

[0017] 2. This utility model, by setting an inner opening block and rotatably connecting an outer opening block to the outer wall of the inner opening block, has multiple nozzles fixed on the outer opening block and corresponding external water guide grooves inside. By rotating the outer opening block, different external water guide grooves can be aligned and connected with the internal water guide grooves of the inner opening block. This solves the problem in the prior art that switching the flushing effect requires changing nozzles or pipelines and is cumbersome to operate, and achieves the effect of simple structure and convenient and quick switching.

[0018] 3. This utility model achieves protection and splash prevention during the rinsing process by setting a visible outer shell; it also achieves effective recycling of rinsing liquid by setting a drain trough. The overall structure is compact and has a high degree of functional integration. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0022] Please refer to Figures 1 to 5 This utility model provides a workpiece rinsing fixture, including a base 1, a visible housing 2 fixedly connected to the top of the base 1, a three-axis guide rail 6 installed on the base 1, and in one embodiment, the three-axis guide rail 6 is installed inside the visible housing 2, a rotating clamping mechanism 3 is installed on the base 1 for clamping and driving the workpiece body 8 to rotate, a drain trough 7 is fixed inside the base 1 and located below the rotating clamping mechanism 3, and a multi-specification rinsing mechanism 4 is installed on the three-axis guide rail 6.

[0023] The rotary clamping mechanism 3 includes a motor 5, one end of a drive shaft 304 fixedly connected to the output end of the motor 5, a rotating block 303, and the drive shaft 304 passing through and slidably connected to the rotating block 303. In a preferred embodiment, the sliding connection between the drive shaft 304 and the rotating block 303 is a spline fit to transmit torque. Multiple steel balls 305 are provided between one side of the rotating block 303 and the inner wall of the base 1 to reduce rotational friction. A rotating shell 301 is rotatably connected to a limiting groove 306 opened on the outer wall of the rotating block 303. Two gripper discs 302 are provided and threadedly connected to the rotating shell 301. In a preferred embodiment, two gripper discs 302 are arranged opposite each other along the axis of the rotating shell 301, and gripper heads 307 are fixed on the gripper discs 302. When it is necessary to clamp the workpiece body 8, the rotating shell 301 is rotated, and the two gripper discs 302 are moved towards or away from each other by means of the threaded connection between the rotating shell 301 and the gripper discs 302, thereby driving the gripper heads 307 to clamp or release the workpiece body 8. After the motor 5 is started, it drives the rotating block 303 and the rotating shell 301, gripper discs 302 and gripper heads 307 fixed on the rotating block 303 to rotate as a whole through the transmission shaft 304, thereby driving the workpiece body 8 to rotate.

[0024] A multi-specification rinsing mechanism 4 is mounted on a three-axis guide rail 6, allowing it to move under the guidance of the guide rail 6, thereby rinsing the workpiece body 8 at multiple positions. The multi-specification rinsing mechanism 4 includes an inner opening block 403, with an inner water guide groove 404 inside the inner opening block 403. An external water pump 402 is an external water pump and is fixedly connected to the inner opening block 403 through a connecting pipe 401, thereby guiding the rinsing liquid into the inner water guide groove 404. An outer opening block 405 is sleeved and rotatably connected to the outer wall of the inner opening block 403. Multiple nozzles 406 are fixedly connected to the outer wall of the outer opening block 405. In a preferred embodiment, the multiple nozzles 406... 6. Different nozzle specifications are provided to achieve different rinsing effects. The outer opening block 405 has an outer water guide groove 407 that is connected to the nozzle 406. The inner water guide groove 404 has an opening facing the outer opening block 405, and the outer water guide groove 407 has an opening facing the inner opening block 403. When it is necessary to switch the nozzle 406, rotate the outer opening block 405 so that the opening of any selected outer water guide groove 407 is aligned with the opening of the inner water guide groove 404. At this time, the water path is opened, and the corresponding nozzle 406 sprays out rinsing liquid. Rotate the outer opening block 405 to another position to switch to another specification of nozzle 406. This switching structure is simple and reliable.

[0025] Multiple steel balls 305 are arranged between one side of the rotating block 303 and the inner wall of the base 1. The steel balls 305 are used to reduce the friction between the rotating block 303 and the base 1 when they rotate. The sliding connection between the transmission shaft 304 and the rotating block 303 is a spline fit. This spline fit structure is used to reliably transmit the torque of the motor 5 while allowing axial sliding. Two gripper disks 302 are provided. The two gripper disks 302 are arranged opposite to each other along the axis of the rotating shell 301 to facilitate stable centering and clamping of the workpiece body 8. A visible outer shell 2 is provided and is fixedly connected to the top of the base 1. Three-axis guide rail 6 Installed inside the visible housing 2, this structure is used for equipment protection and to prevent splashing of rinsing fluid. It is equipped with a drain trough 7, which is fixed inside the base 1 and located below the rotating clamping mechanism 3, for collecting and recovering rinsing fluid. Multiple nozzles 406 have different nozzle specifications so that different rinsing effects can be switched according to rinsing needs. The inner water guide trough 404 has an opening facing the outer opening block 405, and the outer water guide trough 407 has an opening facing the inner opening block 403. The outer opening block 405 is rotated so that the opening of any outer water guide trough 407 is aligned with the opening of the inner water guide trough 404, thereby connecting the water passage.

[0026] Working principle: First, before the workpiece washing operation, the operator rotates the rotating housing 301 in the rotating clamping mechanism 3. Utilizing the threaded connection between the rotating housing 301 and the gripper discs 302, the two opposing gripper discs 302 move axially towards each other, thereby driving the gripper heads 307 fixed thereon to clamp the workpiece body 8. When the operation begins, motor 5 starts. The output end of motor 5 is slidably connected to rotating block 303 via a splined connection through transmission shaft 304, driving rotating block 303 to rotate. Rotating block 303 achieves smooth rotation through steel balls 305 set between it and the inner wall of base 1. Rotating block 303 drives rotating shell 301 to rotate through limiting groove 306 on outer wall. Rotating shell 301 then drives gripper disk 302 and gripper head 307 to rotate synchronously, ultimately realizing the rotation of workpiece body 8 in rotary clamping mechanism 3. While the workpiece body 8 rotates, the multi-specification rinsing mechanism 4 moves to the predetermined rinsing position under the guidance of the three-axis guide rail 6. The three-axis guide rail 6 is mounted on the base 1 and housed inside the visible housing 2. The external water pump 402 pumps the rinsing fluid into the inner water guide groove 404 of the inner opening block 403 through the connecting pipe 401. When switching the rinsing effect is required, rotate the outer opening block 405, which is fitted and connected to the outer wall of the inner opening block 403, so that the opening of one of the outer water guide channels 407 facing the inner opening block 403 aligns with the opening of the inner water guide channel 404 facing the outer opening block 405. At this time, the rinsing fluid is connected and sprayed out from the corresponding nozzle 406 fixed to the outer wall of the outer opening block 405. When it is necessary to switch to another nozzle 406 with a different nozzle specification, simply rotate the outer opening block 405 again so that the opening of the other outer water guide channel 407 aligns with the opening of the inner water guide channel 404. The waste liquid generated during the entire rinsing process is collected by the drain trough 7, which is fixed inside the base 1 and located below the rotating clamping mechanism 3. Through the coordinated work of the rotating clamping mechanism 3 and the multi-specification rinsing mechanism 4, this solution solves the problem of a single rinsing angle for the workpiece and the cumbersome switching of the effect.
