[0002] In the casting production process, the positioning and calibration of the parting surface is a crucial step, as its accuracy directly affects the quality of the casting and the accuracy of subsequent processing.

[0003] Currently, in traditional casting production, the positioning and calibration of the parting surface mainly relies on manual operation. Operators use measuring tools to measure and adjust, which is not only inefficient but also prone to errors due to the subjectivity of manual operation, making it difficult to guarantee the accuracy of positioning and calibration. This can easily lead to problems such as dimensional deviations and irregular shapes in the castings. In addition, manual operation also suffers from high labor intensity and a high degree of dependence on the operator's experience, failing to meet the requirements of automation and high precision in modern casting production. Therefore, this utility model proposes an automatic positioning and calibration fixture for the parting surface of castings. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic positioning and calibration fixture for the parting surface of castings. By setting multiple positioning pins on the positioning mechanism, it can position and fix various types of castings, thereby improving the convenience of the castings during calibration and positioning. At the same time, calibration components are set on both sides of the parting surface of the casting to cooperate with it. Using multiple internal laser displacement sensors, it can accurately detect the angular deviation of the position of the parting surface of the casting, ensuring that the accuracy of the parting surface meets the requirements.

[0005] To solve the above technical problems, the present invention provides an automatic positioning and calibration fixture for casting parting surfaces, including a base, a support plate bolted to the top of the base near one side, a positioning mechanism bolted to the side wall of the support plate, and a casting body engaged with the positioning mechanism.

[0006] The top of the base is bolted to a calibration component, which is installed on the opposite side of the support plate to detect the parting surface of the casting body.

[0008] With the above technical solution, the cylinder is activated, and the drive rods at both ends drive the corresponding push plates to move, so that the connecting plate carrying the positioning plate connected to it slides on the first slide rail through the first slide block, thereby adjusting and fixing the position of the positioning plate, which is convenient for subsequent calibration and testing.

[0012] The above technical solution facilitates the sliding of the calibration plate, which carries multiple calibration sensors and moves stably along the second slide rail via the second slide block, thereby enabling the detection of the parting surface.

[0013] The present invention is further configured such that: the driving mechanism includes a mounting bracket bolted to the top of the base and close to the second slide rail; a servo motor is bolted to one end of the mounting bracket; a lead screw is fixedly connected to the drive shaft of the servo motor; a nut seat is threaded to the outer wall of the lead screw; and one side of the nut seat is bolted to the calibration plate via an L-shaped plate.

[0015] The present invention is further configured such that: the mounting bracket is U-shaped, and the two ends of the lead screw are respectively rotatably connected to the two side walls of the mounting bracket.

[0016] The above technical solution facilitates stable rotation of the lead screw on the inner wall of the mounting frame when it is driven, thereby improving the accuracy of the test.

[0017] The present invention is further configured such that the calibration sensor is a laser displacement sensor and is positioned toward the parting surface of the casting body.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] like Figures 1-4 As shown, an automatic positioning and calibration fixture for a casting parting surface includes a base 1. A support plate 2 is bolted to one side of the top of the base 1. A positioning mechanism 3 is bolted to the side wall of the support plate 2. The positioning mechanism 3 includes a cylinder 31 bolted to the middle of one side of the support plate 2. Push plates 32 are bolted to the end faces of the two drive rods of the cylinder 31. Connecting plates 33 are bolted to the opposite sides of the two push plates 32. Both connecting plates 33 penetrate the support plate 2 and are bolted to positioning plates 34 respectively. Multiple positioning holes 341 are opened near the middle of the two positioning plates 34. Adaptive sleeves 342 can be threaded to the inner walls of the multiple positioning holes 341. Positioning pins 343 are threaded to the inner walls of the positioning holes 341 near both ends of the positioning plates 34. The multiple positioning pins 343 are connected to the casting body 4. The mounting holes are inserted for easy fixing, allowing multiple positioning holes 341 to be used in conjunction with positioning pins 343 to position and fix the casting body 4 that needs to be calibrated and tested. An adaptation sleeve 342 is provided inside the positioning holes 341 to facilitate the installation and fixing of positioning pins 343 for different models of casting bodies 4. The two positioning plates 34 are slidably connected to the first slide rail 36 on the other side of the support plate 2 by bolts to the first slide block 35 near the end face. When the cylinder 31 is activated, the drive rods at both ends drive the corresponding push plate 32 to move, so that the connecting plate 34 carries the positioning plate 34 connected to it to slide on the first slide rail 36 through the first slide block 35, thereby adjusting and fixing the position of the positioning plate 34 to facilitate subsequent calibration and testing. The positioning mechanism 3 is engaged with the casting body 4.

[0031] like Figure 5As shown, a calibration assembly 5 is bolted to the top of the base 1, and the calibration assembly 5 is installed on the opposite side of the support plate 2 to detect the parting surface of the casting body 4. The calibration assembly 5 includes a calibration plate 51 on the side opposite to the parting surface of the casting body 4. Multiple uniformly distributed calibration sensors 52 are arranged on the opposite side of the calibration plate 51 and the casting body 4. The calibration sensors 52 are laser displacement sensors, such as the Keyence IL-600 series and the Mi-Iridium OptoNCDT2300 series, and are set towards the parting surface of the casting body 4, so as to facilitate the non-contact and accurate detection of the position and angle deviation of the parting surface using laser displacement sensors. A second slide block 53 is bolted to the bottom of the calibration plate 51. The second slide block 53 is slidably connected to a second slide rail 54 parallel to the upper surface of the base 1, so that when the calibration plate 51 slides, it can carry multiple calibration sensors 52 through the second slide block 53 to move stably on the second slide rail 54, thereby realizing the detection of the parting surface.

[0032] like Figure 6 As shown, a drive mechanism 6 is bolted to the top of the base 1 to enable the calibration component 5 to perform translational detection on the casting body 4. The drive mechanism 6 includes a mounting bracket 61 bolted to the top of the base 1 and close to the second slide rail 54. A servo motor 62 is bolted to one end of the mounting bracket 61. A lead screw 63 is fixedly connected to the drive shaft of the servo motor 62. The mounting bracket 61 is U-shaped, and the two ends of the lead screw 63 are rotatably connected to the two side walls of the mounting bracket 61, so that when the lead screw 63 is driven, it can rotate stably on the inner wall of the mounting bracket 61, improving the accuracy of the detection. A nut seat 64 is threaded to the outer wall of the lead screw 63. One side of the nut seat 64 is bolted to the calibration plate 51 through an L-shaped plate 65. When the servo motor 62 is started, its output shaft drives the lead screw 63 on the end face to rotate, thereby causing the nut seat 64 threaded to the outer wall to drive the connected calibration plate 51 to slide stably, thereby realizing the detection of the parting surface.

[0033] In use, the cylinder 31 is activated, and the drive rods at both ends of the cylinder drive the corresponding push plate 32 to move. This causes the connecting plate 34, carrying the connected positioning plate 34, to slide on the first slide rail 36 via the first slide block 35, thereby adjusting and fixing the position of the positioning plate 34. Then, the positioning pin 343 is installed on the positioning plate 34, and the casting body 4 is then installed and fixed on the positioning pin 343. Next, the calibration sensor 52 detects the position and angle deviation of the casting parting surface and transmits the data to the externally connected control system. The control system controls the servo motor 62 to work based on the detection data. The servo motor 62 drives the lead screw 63 to rotate, which drives the calibration plate 51 to slide on the second slide rail 54 via the nut seat 64, calibrating the casting parting surface until the predetermined accuracy requirement is achieved.
