Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning seats, and in particular to a positioning seat for sensor sintering. Background Technology
[0002] In the sintering process of sensor bases, the demolding process is a key pain point affecting the integrity rate of finished products and production efficiency.
[0003] Currently, Chinese patent CN214361026U discloses a sintering mold for manufacturing a base, including a graphite pressing table and a base plate. The base plate is provided with several positioning posts, and the sides of the positioning posts are provided with positioning holes. The inner wall of the shell is provided with protrusions. The shell is fitted onto the positioning posts, and the protrusions are engaged with the positioning holes. The above-mentioned existing technical solutions have the following defects: traditional positioning molds mostly rely on manual insertion and removal to complete demolding. Since the base and positioning post are slightly attached after sintering, uneven force when manually removing the parts can easily cause the shell edge to be bumped and deformed. Utility Model Content
[0004] The purpose of this invention is to provide a positioning base for sensor sintering to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A positioning base for sensor sintering includes a base, a worktable fixedly mounted on the top of the base, a slide rail fixedly mounted on the top of the worktable, the slide rail being arranged in a front-rear direction, a positioning unit slidably mounted on the top of the slide rail, the positioning unit being used to adjust the positioning position of the sensor base, a positioning column fixedly mounted on the top of the positioning unit, the positioning column being used to position the sensor housing and core column, and a demolding mechanism integrated inside the base corresponding to the position of the positioning column, the demolding mechanism being used to push the sintered sensor base out from the positioning column.
[0006] By adopting the above technical solution, the base serves as the overall support foundation, the worktable provides a stable operating plane, and the cooperation between the slide rail and the positioning unit allows the positioning column to slide flexibly in the front and back directions, thereby adjusting the positioning position according to the specifications of the sensor base and adapting to the processing requirements of different sizes; at the same time, the integrated demolding mechanism can quickly remove the finished product after sintering, avoiding damage to the parts that may be caused by manual removal. The overall structure takes into account both flexibility and ease of operation.
[0007] In a further embodiment, the positioning unit includes a slider, a locking knob, and a stop block. The slider is slidably mounted on the slide rail. The top of the slider is fixedly connected to the bottom of the positioning post. A locking knob is screwed to the side of the slide rail. One end of the locking knob passes through the side wall of the slide rail and a stop block is fixedly mounted thereon. The stop block abuts against the inner wall of the slider and is used to fix the position of the slider on the slide rail.
[0008] By adopting the above technical solution, the locking knob abuts against the inner wall of the slider, which can firmly fix the slider on the slide rail, avoiding positioning deviation caused by vibration and other factors during the sintering process. This ensures both the flexibility of adjustment and the stability of positioning.
[0009] In a further embodiment, the positioning post includes a post body, a limiting sleeve, and an elastic locking pin. The post body has a through first mounting hole in the axial direction. The limiting sleeve is interference-fitted in the first mounting hole. The inner wall of the limiting sleeve is used to accommodate the sensor core post. The side of the post body has symmetrical dovetail grooves in the axial direction. The bottom of the dovetail grooves has a second mounting hole. An elastic locking pin is provided in the second mounting hole. The elastic locking pin is used to engage the protrusion of the sensor housing.
[0010] By adopting the above technical solution, the limiting sleeve is interference-fitted with the first mounting hole, and the limiting sleeve with different inner diameters can be replaced according to the core column diameter to adapt to various specifications of core columns; the dovetail groove on the side of the column cooperates with the sensor housing protrusion to restrict the radial rotation of the housing and prevent the core column from shifting in orientation; the elastic locking pin engages with the housing protrusion to fix the axial position of the housing and prevent the housing from shifting up and down during sintering.
[0011] In a further embodiment, the demolding mechanism includes an ejector pin, an L-shaped lever, and a linkage lever. An ejector pin is provided inside the base at a position corresponding to the positioning post. The top of the ejector pin passes through the worktable and extends to the bottom of the positioning post. An L-shaped lever is provided at the bottom of the ejector pin. The middle part of the L-shaped lever is rotatably connected to the inner wall of the base through a fulcrum. The end of the L-shaped lever away from the ejector pin is connected to a linkage lever. One end of the linkage lever extends to the outside of the base.
[0012] By adopting the above technical solution, turning the linkage lever can drive all L-shaped levers to rotate synchronously. The levers lift the ejector pin around the fulcrum, and the ejector pin pushes out the sintered base from below the positioning column. There is no need for manual insertion and removal, which saves effort and avoids deformation of the shell or core column caused by manual removal, greatly improving demolding efficiency and finished product integrity.
[0013] In a further embodiment, the top of the slider is provided with a through hole that extends vertically, the through hole being used to avoid the ejector pin.
[0014] By adopting the above technical solution, the clearance hole provides movement space for the ejector pin, ensuring that the ejector pin can smoothly pass through the slider and contact the bottom of the base during demolding, avoiding the slider from blocking the ejector pin, and ensuring smooth structural cooperation between the demolding mechanism and the positioning unit without affecting the realization of their respective functions.
[0015] In a further embodiment, the top of the column is provided with an annular positioning step, which is used to support the glass blank to be sintered.
[0016] By adopting the above technical solution, the annular positioning step can provide stable support for the glass blank, ensuring that the glass blank is in a horizontal state before sintering. It can automatically calibrate the center position of the glass blank, aligning it with the axis of the core column and shell, ensuring that the molten glass can uniformly fill the sealing gap during sintering and improving the sealing quality.
[0017] In a further embodiment, the base is provided with leveling components at each of the four bottom corners. The leveling components include screws and support seats. The top end of the screw is fixedly connected to the bottom of the base, the top of the support seat is provided with a threaded hole, and the bottom end of the screw is screwed into the threaded hole.
[0018] In summary, this utility model has the following beneficial effects: 1. The clearance holes provide space for the ejector pins to move, ensuring that the ejector pins can smoothly pass through the slider and contact the bottom of the base during demolding. This avoids the slider blocking the ejector pins, ensuring smooth structural cooperation between the demolding mechanism and the positioning unit, and not affecting the performance of their respective functions.
