Description

Technical Field

[0001] This utility model belongs to the field of bearing drilling technology, and specifically relates to a drilling device for bearing housing production. Background Technology

[0002] In the machining process of bearing housings, the first step is to determine the machining datum, which is a prerequisite for ensuring the accuracy of all subsequent processes.

[0003] Then, based on the product's design requirements and material properties, a detailed process flow is developed. As one step in the processing flow, drilling is typically performed using a drilling machine with specialized fixtures to precisely control the position of the bearing housing on the machine tool. This includes a turntable with multiple fixed stations used to clamp and position the bearing housing to be processed. Each station is equipped with a drilling mechanism and a tapping mechanism, which can automatically complete the drilling and tapping processes as the bearing housing passes by.

[0004] In the existing technology, a large amount of metal shavings are generated when the bearing housing is drilled and tapped. Although some of them are sent to the hopper by the cutting fluid during the machining process, some shavings are still left on the turntable. Moreover, the shavings in the hopper gradually accumulate after the drilling work is completed, and still need to be manually removed. This is not only time-consuming and labor-intensive, but also delays the efficiency of subsequent drilling work. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for bearing housing production. The fixed platform can extend the cutting fluid mixed with metal shavings through the funnel to the conical disc. The fluid is then guided by the conical disc to fall to the bottom of the hopper. During drilling, the rotation of the fixed platform drives the scraper to rotate and automatically scrape the metal shavings to the bottom of the sealing plate. This eliminates the need for manual cleaning after stopping the machine, saving time and effort and improving drilling efficiency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A bearing housing drilling device includes a circular hopper fixedly assembled on top of a support platform. Support seats are fixedly connected in an array to the top of the support platform and outside the hopper. A conical disc is rotatably assembled in the middle of the hopper. Connecting rods are fixedly connected in an array to the top of the conical disc. A fixed platform is fixedly connected to the conical disc via the connecting rods. A funnel is formed through the middle of the fixed platform above the conical disc. Protruding plates are symmetrically fixedly connected to the outer wall of the fixed platform. Vertical rods are fixedly connected to the bottom of each protruding plate. A scraper is fixedly connected to one end of each vertical rod, close to the inner wall of the hopper. Sealing plates are slidably connected to the bottom of the hopper and on both sides of the conical disc.

[0008] A drilling mechanism is fixedly assembled on the top of the support base, and a connecting rod is fixedly connected to the bottom of the sealing plate and below the hopper.

[0009] The hopper is symmetrically slidably connected to sliding rods on both sides, and the sliding rods are fixedly connected to the connecting rods.

[0010] The sliding rod is fixedly connected to an arc-shaped plate at one end inside the hopper, and the arc-shaped plate is fitted to the outside of the fixed platform.

[0011] The hopper is symmetrically and elastically assembled with spring columns on both sides, and the connecting rod is fixedly connected to the spring columns.

[0012] The support base has a through slot in the middle for the connecting rod and sliding rod to pass through.

[0013] The technical effect achieved by this utility model is as follows: the fixed table can extend the cutting fluid mixed with metal wires through the funnel to the conical disk, and the fluid will fall to the bottom of the hopper through the guidance of the conical disk. When drilling, the rotation of the fixed table will drive the scraper to rotate and automatically scrape the metal wires to the bottom of the sealing plate. There is no need to stop the machine for manual cleaning, which saves time and effort and improves the drilling efficiency. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a bearing housing drilling device includes a hopper 101 fixedly assembled on the top of a support platform 1. The hopper 101 is circular. Support seats 102 are fixedly connected in an array on the top of the support platform 1 and outside the hopper 101. A drilling mechanism 104 is fixedly assembled on the top of the support seats 102. A conical disk 105 is rotatably assembled in the middle of the hopper 101. Connecting rods 106 are fixedly connected in an array on the top of the conical disk 105. A fixed platform 107 is fixedly connected to the conical disk 105 through the connecting rods 106. A funnel 108 is provided through the middle of the fixed platform 107 and above the conical disk 105. Protruding plates 109 are symmetrically fixedly connected to the outer wall of the fixed platform 107. Vertical rods 111 are fixedly connected to the bottom of each protruding plate 109. One end of each vertical rod 111 is attached to... A scraper 116 is fixedly connected to the inner wall of the hopper 101. A sealing plate 110 is slidably connected to the bottom of the hopper 101 and to both sides of the conical disc 105. A connecting rod 114 is fixedly connected to the bottom of the sealing plate 110 and to the bottom of the hopper 101. Sliding rods 113 are symmetrically slidably connected to both sides of the hopper 101. The sliding rods 113 are fixedly connected to the connecting rods 114. An arc plate 112 is fixedly connected to one end of the sliding rod 113 inside the hopper 101. The arc plate 112 is fitted to the outside of the fixed platform 107. Spring columns 115 are symmetrically elastically assembled on both sides of the hopper 101. The connecting rods 114 are fixedly connected to the spring columns 115. A through slot 103 is provided in the middle of the support base 102 for the connecting rods 114 and the sliding rods 113 to move through.

[0022] According to the above structure, the drilling mechanism 104 processes the bearing workpiece fixed on the fixed table 107. In the prior art, the fixed table 107 is mostly a one-piece cast disc that rotates intermittently to facilitate processing by different drilling mechanisms 104. The cutting fluid is sprayed onto the bearing workpiece from one side of the drilling mechanism 104. In this example, the cutting fluid carrying metal shavings flows down through the funnel 108, which is wider at the top and narrower at the bottom, and continues to flow to the bottom of the hopper 101 through the conical inclined surface of the conical disc 105. At this time, the sealing plate 110 is in a closed state, and the metal shavings and cutting fluid accumulate together at the bottom of the hopper 101. When the fixed platform 107 rotates continuously, it can drive the convex plate 109 to rotate as well. The convex plate 109 drives the vertical rod 111 and the scraper 116 to rotate as well. The scraper 116 carries the metal shavings at the bottom of the hopper 101 toward the sealing plate 110. Due to the presence of cutting fluid, the scraping and conveying work of the scraper 116 is more smooth. When the convex plate 109 rotates and squeezes the arc plate 112, the sliding rod 113 drives the connecting rod 114 to move outward. The through slot 103 opened in the support base 102 provides sliding space for it. Rod 114 moves the sealing plate 110, and the bottom of the hopper 101 is no longer sealed. The cutting fluid and metal shavings scraped by scraper 116 flow into the area below the sealing plate 110 and are recovered by the recycling device inside the support platform 1. When the convex plate 109 rotates and no longer squeezes the arc plate 112, the sliding rod 113 and connecting rod 114 rebound under the pull of spring column 115, so that the sealing plate 110 is reset. This utility model can extend the cutting fluid mixed with metal shavings through the funnel 108 to the conical disk 105 through the fixed platform 107. The fluid falls into the bottom of the hopper 101 through the guide of the conical disk 105. When drilling, the rotation of the fixed platform 107 drives the scraper 116 to rotate and automatically scrape the metal shavings to the area below the sealing plate 110. There is no need to stop the machine for manual cleaning, which saves time and effort and improves the working efficiency of drilling.

[0023] The working principle of this utility model is as follows: The drilling mechanism 104 processes the bearing workpiece fixed on the fixed platform 107. In the prior art, the fixed platform 107 is mostly a one-piece cast disc that rotates intermittently to facilitate processing by different drilling mechanisms 104. The cutting fluid is sprayed onto the bearing workpiece from one side of the drilling mechanism 104. In this example, the cutting fluid carrying metal shavings flows down through the funnel 108, which is wider at the top and narrower at the bottom, and continues to flow to the bottom of the hopper 101 through the conical inclined surface of the conical disc 105. At this time, the sealing plate 110 is in a closed state, and the metal shavings and cutting fluid accumulate together at the bottom of the hopper 101. When the fixed platform 107 rotates continuously, it can drive the convex plate 109 to rotate together. The convex plate 109 drives the vertical rod 111 and the scraper 116 to rotate together. The scraper 116 carries the metal shavings at the bottom of the hopper 101 toward the sealing plate 110. Due to the presence of the cutting fluid, the scraper 116 can effectively scrape and convey the metal shavings. To facilitate smoother operation, when the convex plate 109 rotates and presses the arc plate 112, the sliding rod 113 drives the connecting rod 114 to move outward. The through slot 103 opened in the support seat 102 provides sliding space for it. The connecting rod 114 drives the sealing plate 110 to move, and the bottom of the hopper 101 is no longer closed. The cutting fluid and metal shavings scraped by the scraper 116 flow into the area below the sealing plate 110 and are recovered by the recycling device inside the support platform 1. When the convex plate 109 rotates and no longer presses the arc plate 112, the sliding rod 113 and the connecting rod 114 rebound under the pull of the spring column 115, so that the sealing plate 110 is reset.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
