Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of feeding mechanism for warping workpiece, belong to vibrating screen technical field. BACKGROUND
[0002] In the compressor manufacturing field, the manufacturing precision of valve plate is crucial to ensure the overall performance of compressor. For example, the warped valve plate is provided with a hole at one end to facilitate assembly, and the other end presents a warped shape. This design aims to meet the specific fluid dynamics requirements inside the compressor. However, the warped height of the valve plate is a critical dimension parameter, and its precision needs to be strictly controlled within ±0.1mm. The size of this tolerance directly affects the operating efficiency, sealing performance, and overall reliability of the compressor. If the warped height of the valve plate deviates from the tolerance range, it may lead to decreased compressor performance, increased energy consumption, and even faults.
[0003] Currently, for the detection of the warped height of such valve plates, a detection scheme combining a dial gauge and a fixed block is commonly used. The operation process of this scheme is relatively intuitive: first, the valve plate to be detected is securely fixed to the bottom of a specially designed fixed block using bolts to ensure the stability of the valve plate position during the detection process. Then, a dial gauge is installed on the fixed block, and the measuring needle of the dial gauge penetrates through the pre-designed hole in the fixed block to directly touch the warped end of the valve plate for measurement. This detection method relies on the high-precision reading ability of the dial gauge and can accurately reflect the actual deviation of the warped height of the valve plate.
[0004] Although this detection scheme based on dial gauge and fixed block is technically feasible, and the required clamp structure is relatively simple, easy to operate and maintain, but since the detection process needs to be operated manually one by one, it not only takes a long time, but also is difficult to achieve rapid batch detection, so in actual production, it is usually only possible to take the way of sampling inspection, i.e. only a part of the valve plates in each production batch are detected. Although this approach reduces the detection cost to some extent, it also means that the size qualification rate of all production parts cannot be fully and accurately grasped, and only limited detection data can be used for estimation. This estimation method reflects the overall quality trend to some extent, but it is obviously insufficient to ensure that each batch of valve plates meets the strict tolerance requirements.
[0005] Therefore, there is a need for a system that can efficiently and automatically detect the warped height of workpieces in batches. In this system, how to ensure that the workpieces are transported in a uniform orientation and accurately detected is a key technical problem that needs to be solved. UTILITY MODEL CONTENTS

Therefore, these terms should not be construed as restrictive interpretations of the content of this application.
[0035] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0036] like Figures 1-6 As shown, a feeding mechanism for warped workpieces includes a frame 3, a feeder 1, and a vibrating feeder 2. The feeder 1 and the vibrating feeder 2 are mounted on the frame 3. The vibrating feeder 2 includes a base 201 and a screening cylinder 202. The screening cylinder 202 is mounted on the base 201. A vibrator is provided inside the base 201 and is connected to the screening cylinder 202. A spiral channel 203 is provided inside the screening cylinder 202. A discharge port is provided on the cylinder wall of the screening cylinder 202. The end of the spiral channel 203 is connected to the discharge port. A baffle 204 is provided above the spiral channel 203 for removing overlapping workpieces. A retaining edge is provided on the side of the spiral channel 203 away from the cylinder wall of the screening cylinder 202. The height of a portion of the retaining edge is higher than the thickness of the workpiece to be conveyed, and the height of a portion of the retaining edge is less than the thickness of the workpiece to be conveyed. The feeder 1 is used to quantitatively convey the workpiece into the screening cylinder 202.
[0037] The screening cylinder 202 is also provided with a transition channel 207. One end of the transition channel 207 is connected to the discharge port of the screening cylinder 202, and the other end is used to connect to external equipment.
[0038] The baffle 204 is adjustablely installed above the spiral feed channel 203. The distance between the baffle 204 and the spiral feed channel 203 can be adjusted according to the actual screening requirements and the thickness of the workpiece, thereby meeting different process requirements.
[0039] A limiting pressure plate 208 is also provided above the transition channel 207 to prevent the workpiece from jumping during the conveying process. The limiting pressure plate 208 restricts the jumping of the workpiece during the conveying process, ensuring that the workpiece can enter the sliding chute smoothly and accurately, reducing production delays or quality problems caused by unstable workpiece position.
[0040] The feeder 1 includes a hopper 101 and a vibrating conveyor 102. The hopper 101 is equipped with a vibrator, and the vibrating conveyor 102 is located at the lower end of the hopper 101, used to quantitatively transport the workpieces in the hopper 101 to the screening cylinder 202. The vibrator on the hopper 101 vibrates, allowing the workpieces to fall orderly through the opening at the bottom of the hopper 101 onto the vibrating conveyor 102. The vibrating conveyor 102 then stably transports the workpieces into the screening cylinder 202 according to a preset conveying speed and frequency, ensuring the accuracy and continuity of workpiece transport. This feeder 1 achieves automated transport, greatly reducing the need for manual intervention. Operators only need to place the valve plate 10 to be tested into the hopper 101, and the feeder 1 can automatically complete the subsequent transport work, thereby reducing labor intensity and improving production efficiency.
[0041] The vibrating conveyor 102 is also equipped with a baffle plate 103 at its discharge port. The baffle plate 103 is positioned above the discharge port of the vibrating conveyor 102 and is used to limit the discharge volume of the vibrating conveyor 102. By setting the baffle plate 103, the number of workpieces output from the discharge port of the vibrating conveyor 102 can be controlled more precisely. This helps to ensure that the number of workpieces conveyed into the screening cylinder 202 each time is appropriate, and avoids too many workpieces entering the screening cylinder 202 at the same time.
[0042] The upper end of the screening cylinder 202 is open, which allows the workpiece to smoothly enter the screening cylinder 202 from the vibrating conveyor 102, and also facilitates observation and inspection of the working status inside the screening cylinder 202.
[0043] The inner wall of the screening cylinder 202 is provided with a wear-resistant layer. During the workpiece conveying and screening process, the inner wall of the screening cylinder 202 will rub and collide with the workpiece. The presence of the wear-resistant layer can effectively reduce the wear of the inner wall of the screening cylinder 202 caused by such friction and collision, thereby extending the service life of the screening cylinder 202. At the same time, the wear-resistant layer can also improve the surface hardness and smoothness of the screening cylinder 202, which helps to reduce the jamming and wear of the workpiece during the screening process.
[0044] In this embodiment, with Figure 7 and Figure 8 The working process and working principle of the feeding mechanism for warped workpieces of this utility model are explained by taking the warped valve plate 10 as an example. The valve plate 10 in the figure is warped at one end and has a positioning hole at the other end. One side of it is concave and the other side is convex. The concave side is set as the front side and the convex side is set as the back side. The warped end is the front end and the end with the positioning hole is the rear end.
[0045] After the valve plate 10 to be tested is placed into the hopper 101, the vibrator on the hopper 101 of the feeder 1 is activated, and the vibrator will generate a vibration to drive the hopper 101 to vibrate. Under the vibration, the valve plate 10 will gradually fall through the opening at the lower end of the hopper 101 onto the vibrating conveyor 102. The vibrating conveyor 102 then steadily and continuously conveys these valve plates 10 into the screening cylinder 202 of the vibrating feeder 2 in a quantitative manner. In the vibrating feeder 2, the valve plate 10 is conveyed into the sliding chute with its front side facing up and its back side facing down. The specific working process is as follows:
[0046] After the vibrator is started, the irregularly stacked valve plates 10 located at the bottom of the screening cylinder 202 will successively enter the spiral feed channel 203 inside the screening cylinder 202 and move towards the outlet side along the spiral feed channel 203. Since the width of the spiral feed channel 203 is approximately equal to the width of one valve plate 10, only one row of valve plates 10 can pass through at a time. When the valve plates 10 enter the spiral feed channel 203, they may be facing upwards, backwards, or overlapping. When the valve plates 10 pass through the baffle 204, the overlapping valve plates 10 will be blocked by the baffle 204, and only a single workpiece can pass through the feed channel below the baffle 204. The valve plates 10 that have passed through the baffle 204 continue to advance along the spiral feed channel 203. When the valve plates 10 pass through the feed channel area with the low baffle 205, the valve plates 10 facing backwards will fall back into the screening cylinder 202 from the side of the low baffle 205 under the vibration of the vibrator, while the low baffle 205 can effectively prevent the valve plates 10 facing forwards from falling. Therefore, the valve plate 10 with its front facing upwards can smoothly pass through the spiral feed channel 203 and enter the sliding trough in sequence.
[0047] The feeder 1 of this utility model is used to quantitatively transport workpieces to the vibrating feeder 2. The vibrating feeder 2 is used to arrange workpieces in a predetermined orientation and transport them to the sliding chute. The vibrating feeder 2 removes overlapping workpieces by setting a baffle 204 above the spiral feed channel 203, ensuring that only a single workpiece can pass through. Furthermore, different heights of guards are provided on the spiral feed channel 203. The high guard 206 can prevent the workpiece from slipping. When the valve plate 10 passes through the spiral feed channel 203 with the low guard 205, its passage will vary depending on the orientation of the valve plate 10. Specifically, if the concave surface of the valve plate 10 faces upward and the convex surface faces downward, the contact area between its convex surface and the spiral feed channel 203 is large, and the side of the valve plate 10 can also contact the low guard 205. The low guard 205 can prevent the valve plate 10 from slipping, and the valve plate 10 can pass smoothly. If the concave surface of the valve plate 10 faces downward and the convex surface faces upward, the contact area between its concave surface and the spiral feed channel 203 is small, and the middle position of the valve plate 10 is higher than the low guard 205, and the side of the valve plate 10 is higher than the low guard 205. Therefore, the valve plate 10 with its concave surface facing downward will slip and fall into the screening cylinder 202 under the action of vibration. In this way, automatic screening and directional conveying of workpieces are achieved. The vibrator enables the workpieces in the screening cylinder 202 and the spiral feed channel 203 to move continuously and stably.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
