Description

Technical Field

[0001] This utility model relates to the field of mold testing equipment technology, and in particular to a high-precision testing platform for water pump body casting molds. Background Technology

[0002] The pump body is a core component of fluid machinery, and the precision of its casting mold directly determines the performance and quality of the final product. Because pump bodies typically have complex internal cavities and curved surface structures, high-precision three-dimensional dimensional inspection is required before the mold is put into production to ensure that all technical indicators meet design requirements.

[0003] In existing automated inspection processes, an inspection platform is typically used to support and position the mold, and then scanning equipment is used to collect data from the mold surface. However, before inspection, the mold to be tested must first be transported from the outside and accurately positioned within the working area of ​​the inspection platform. This process is usually completed by a separate loading or handling mechanism.

[0004] This design, which separates the feeding and inspection functions, means that the entire inspection system typically requires at least two independent actuators: one for gripping and placing the mold, and the other for driving the scanning head. This layout not only makes the mechanical structure of the entire device very complex and requires a large footprint, but the switching and coordination between the two independent mechanisms also reduces the overall automation integration and work efficiency.

[0005] Therefore, this utility model proposes a high-precision testing platform for water pump body casting molds to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a high-precision inspection platform for water pump body casting molds, aiming to improve the existing mold inspection devices, which have a separate structure, making it difficult to realize the integrated automatic process of feeding, flipping and scanning inspection, resulting in complex structure, large footprint and low inspection efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision testing platform for water pump body casting molds, comprising: an adjustment mechanism and a feeding testing mechanism; the adjustment mechanism comprises a main body rotatable around a central axis; the feeding testing mechanism comprises a base plate, a slide rod fixedly connected to the base plate, and a slide plate slidably connected to the slide rod.

[0008] The skateboard is fixedly connected to a first bracket and a second bracket on the same side.

[0009] The first bracket has a processing device with a scanning head fixedly connected to its top, while the second bracket has a slide for holding the mold fixedly connected to its top. By fixing the first and second brackets, which carry different functions, together on the same slide plate, the feeding and scanning actions can be switched in a time-sharing manner through the reciprocating linear motion of the same slide plate. This integrates the two major functions of feeding and detection into one, greatly simplifying the equipment structure.

[0010] Preferably, a toothed ring is fixedly sleeved on the outer wall of the main body; the adjustment mechanism further includes a motor bracket, on which a motor is mounted, and the output shaft of the motor is connected to a gear that meshes with the toothed ring.

[0011] Preferably, a support frame is fixedly connected to the inner wall of the main body by a fixing rod; a first electric telescopic rod is fixedly installed on the support frame, and a pressure plate is connected to the output end of the first electric telescopic rod. The pressure plate is located inside the support frame and faces the mold inside the support frame.

[0012] Preferably, a second electric telescopic rod is also fixedly installed on the base plate, and the output end of the second electric telescopic rod is fixedly connected to the slide plate to drive the slide plate to reciprocate along the slide rod.

[0013] Preferably, a third electric telescopic rod is fixedly installed inside the slide, and an electric suction cup is connected to the output end of the third electric telescopic rod.

[0014] Preferably, a fourth electric telescopic rod is fixedly installed on the processing device, and the scanning head is connected to the output end of the fourth electric telescopic rod.

[0015] Preferably, the adjustment mechanism further includes a base, and the main body is rotatably mounted on top of the base.

[0016] Preferably, the positioning mechanism and the feeding detection mechanism are mounted on the same frame, and the axial direction of the slide rod is parallel to the central axis of the opening of the main body.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by integrating a second support for feeding and a first support for scanning side by side on the same movable slide, and by using the reciprocating linear motion of the slide to achieve time-sharing switching of the two functions, the problem of the separation of feeding and detection devices in the prior art, which leads to a complex overall equipment structure and a large footprint, is solved. This achieves the technical effect of a highly compact structure, saving equipment space and simplifying the control system.

[0018] 2. In this utility model, the integrated feeding and detection mechanism and the rotatable adjustment mechanism work together to realize the fully automated process of mold from automatic feeding, clamping, scanning, automatic flipping to multi-face repeated scanning. This solves the problem that in the prior art, when inspecting complex molds, manual flipping and repeated clamping are required, resulting in high labor intensity, low efficiency and difficulty in ensuring positioning accuracy. It achieves the technical effect of significantly improving inspection efficiency and ensuring high consistency of inspection data.

[0019] 3. In this utility model, by setting a pressure plate driven by an electric telescopic rod on the bearing frame inside the rotating body, the mold is clamped down forcefully, which solves the problem that the mold will have a slight displacement or vibration due to unstable clamping during the detection process, which affects the measurement accuracy. This achieves the technical effect of providing a stable measurement benchmark for high-precision scanning and effectively ensuring the reliability of scanning data. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides a high-precision testing platform for water pump body casting molds, which aims to solve the problems of existing mold testing devices having separate structures, making it difficult to achieve an integrated automatic process of feeding, flipping and scanning testing, resulting in complex structures, large footprints and low testing efficiency.

[0024] The high-precision inspection platform for the water pump body casting mold includes an adjustment mechanism 1 and a feeding inspection mechanism 2. The adjustment mechanism 1 and the feeding inspection mechanism 2 are mounted on the same frame and cooperate with each other. The adjustment mechanism 1 is used to rotate, position and clamp the mold 108, while the feeding inspection mechanism 2 is used to transport the mold 108 and perform scanning inspection actions.

[0025] Specifically, the feeding and detection mechanism 2 includes a base plate 201, on which a slide rod 202 is fixedly connected. A slide plate 203 is slidably connected to the slide rod 202 through an internal sliding hole. A second electric telescopic rod 204 is also fixedly installed on the base plate 201. The output end of the second electric telescopic rod 204 is fixedly connected to the slide plate 203 and is used to drive the slide plate 203 to reciprocate linearly along the axis of the slide rod 202.

[0026] To integrate the feeding and detection functions, a first bracket 205 and a second bracket 206 are fixedly connected side-by-side on the same surface of the slide plate 203. The first bracket 205 and the second bracket 206 move synchronously with the slide plate 203. By stopping the slide plate 203 at different positions, the functions carried by the two brackets are executed in a time-sharing manner. Among them, the first bracket 205, which serves as the carrier of the detection function, has a processing device 2011 fixedly connected to its top. A fourth electric telescopic rod 2012 is further fixedly installed on the processing device 2011. The scanning head 2013 is connected to the output end of the fourth electric telescopic rod 2012. The extension and retraction of the fourth electric telescopic rod 2012 drives the scanning head 2013 to perform linear scanning motion. The second bracket 206, which serves as the carrier of the feeding function, has a slide groove 207 fixedly connected to its top for holding the mold 108 to be tested. To realize the automatic pushing of the mold 108, a third electric telescopic rod 208 is also fixedly installed inside the slide groove 207. The output end of the third electric telescopic rod 208 is connected to an electric suction cup 209.

[0027] The adjustment mechanism 1, which cooperates with the feeding and detection mechanism 2, includes a base 101. The main body 102 is rotatably mounted on the base 101. In order to drive the main body 102 to rotate precisely, a gear ring 103 is fixedly sleeved on the outer wall of the main body 102. The adjustment mechanism 1 also includes a motor bracket 109. A motor 1011 is mounted on the motor bracket 109. The output shaft of the motor 1011 is connected to a gear 1012. The gear 1012 and the gear ring 103 always maintain a meshing transmission relationship.

[0028] A support frame 105 is fixedly connected to the inner wall of the main body 102 by multiple evenly distributed fixing rods 104. The support frame 105 is a hollow frame structure. The inner cavity size of the support frame 105 is adapted to the mold 108 to be tested, and is used to accommodate and initially position the mold 108 pushed from the feeding and detection mechanism 2. In order to firmly lock the mold 108 during subsequent scanning and rotation to prevent any slight displacement, a first electric telescopic rod 106 is fixedly installed on the support frame 105. The output end of the first electric telescopic rod 106 is connected to a pressure plate 107. The pressure plate 107 is located inside the support frame 105 and faces the upper surface of the mold 108 inside the support frame 105. In operation, after the mold 108 is placed in the support frame 105, the first electric telescopic rod 106 retracts, which drives the pressure plate 107 to move downward, so that the bottom surface of the pressure plate 107 is tightly pressed against the upper surface of the mold 108. This multi-point driven downward clamping structure can provide a strong and uniform clamping force, thereby ensuring that the mold 108 remains absolutely stationary when the main body 102 rotates at high speed or the scanning head 2013 reciprocates, providing a stable and reliable structural foundation for high-precision detection.

[0029] The coordinated control of the first electric telescopic rod 106, the second electric telescopic rod 204, the third electric telescopic rod 208, the fourth electric telescopic rod 2012, and the motor 1011 is achieved by an external central programmable logic controller (PLC) according to a preset program. The specific circuit design and programming of the central controller are well-known technologies in this field and will not be described in detail here.

[0030] In a preferred embodiment, in order to achieve automated and precise rotation of the main body 102, a gear ring 103 is fixedly sleeved on the outer wall of the main body 102. The positioning mechanism 1 also includes a motor bracket 109, which is fixedly installed on the side of the base 101. A motor 1011 is installed on the motor bracket 109. The output shaft of the motor 1011 is connected to a gear 1012 through a coupling. The gear 1012 precisely meshes with the tooth profile of the gear ring 103. By controlling the start, stop and rotation angle of the motor 1011, the main body 102 can be driven to rotate at any angle and be precisely positioned.

[0031] In a preferred embodiment, in order to provide a stable and controllable driving force for the linear reciprocating motion of the slide plate 203, a second electric telescopic rod 204 is fixedly installed on the base plate 201. The output end of the second electric telescopic rod 204 is fixedly connected to the rear end face of the slide plate 203 through a connector. The extension stroke of the second electric telescopic rod 204 matches the effective length of the slide rod 202, ensuring that the slide plate 203 can completely cover the entire stroke from the initial feeding position to the detection working position.

[0032] In a preferred embodiment, in order to automatically push the mold 108 to be tested from the slide 207 into the support frame 105, a third electric telescopic rod 208 is fixedly installed inside the slide 207. An electric suction cup 209 is fixedly connected to the output end of the third electric telescopic rod 208. The electric suction cup 209 is connected to an external air pipe through an internal vacuum generator and can generate an adsorption force on the surface of the mold 108, thereby driving the mold 108 to move synchronously when the third electric telescopic rod 208 extends.

[0033] In a preferred embodiment, in order to achieve high-precision scanning of the surface of the mold 108, a fourth electric telescopic rod 2012 is fixedly installed on the processing device 2011, and the scanning head 2013 is fixedly connected to the output end of the fourth electric telescopic rod 2012. Through the reciprocating telescopic movement of the fourth electric telescopic rod 2012, the scanning head 2013 can be driven to collect data in a single dimension.

[0034] In a preferred embodiment, in order to provide a stable installation foundation for the entire adjustment mechanism 1, the adjustment mechanism 1 includes a base 101, and the main body 102 is rotatably mounted on the upper surface of the base 101 via a large turntable bearing. The base 101 is fixed to the equipment frame by anchor bolts to ensure the stability of the rotation process.

[0035] As a preferred embodiment, in order to ensure that the feeding detection mechanism 2 and the adjusting mechanism 1 can achieve precise docking without interference, the adjusting mechanism 1 and the feeding detection mechanism 2 are installed on the same horizontal plane of the same equipment frame, and the axial direction of the slide rod 202 of the feeding detection mechanism 2 is precisely parallel to the central axis of the opening of the main body 102, so as to ensure that the first support 205 and the second support 206 can accurately enter or exit the internal space of the main body 102 during linear movement.

[0036] Working principle: In use, the mold 108 is first placed in the slide groove 207 of the feeding detection mechanism 2. Then, the second electric telescopic rod 204 is activated and pushes the slide plate 203 along the slide rod 202 to move towards the adjustment mechanism 1. This movement causes the second bracket 206 fixed on the slide plate 203 to enter the body 102. When the slide plate 203 reaches the predetermined feeding position, the third electric telescopic rod 208 in the slide groove 207 extends and drives the electric suction cup 209 at its end to attract and push the mold 108, accurately sending the mold 108 into the carrier frame 105 of the adjustment mechanism 1. After the mold 108 is in place, the first electric telescopic rod 106 on the carrier frame 105 performs a retraction action, causing the pressure plate 107 to move downward and firmly press the mold 108.

[0037] After the clamping action is completed, the second electric telescopic rod 204 moves in the opposite direction, driving the slide plate 203 to move backward. This backward movement causes the second support 206 for feeding to exit the main body 102, while bringing the first support 205 for detection into the main body 102, so that the scanning head 2013 on the first support 205 moves to above the surface to be tested on the mold 108. When scanning starts, the fourth electric telescopic rod 2012 drives the scanning head 2013 to perform reciprocating linear motion in the first dimension. At the same time, the second electric telescopic rod 204 can cooperate to perform stepping or uniform translation, driving the entire slide plate 203 to move in the second dimension. Through the synthesis of the two-dimensional motion, the scanning coverage of the entire surface of the mold 108 is achieved.

[0038] After the single-sided inspection of mold 108 is completed, the second electric telescopic rod 204 drives the slide plate 203 to move, so that the first support 205 and the scanning head 2013 completely exit the main body 102; then the motor 1011 starts, drives the gear ring 103 through the gear 1012, and drives the main body 102, together with the internal support frame 105 and mold 108, to rotate, flipping the other test surface of mold 108 to the upward position; then, the aforementioned slide plate 203 insertion and scanning operation is repeated until all surfaces of mold 108 that need to be inspected are inspected; by integrating the feeding and inspection functions on the same movable slide plate 203, and with the rotatable adjustment mechanism 1, a high degree of automation and integration of the mold inspection process is achieved.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
