Technical Field

[0001] This utility model relates to the field of high-speed flat pre-grinding machine technology, specifically to a bridge gantry frame structure for a high-speed flat pre-grinding machine. Background Technology

[0002] A pre-grinding machine is a grinding machine that uses abrasive-coated or embedded grinding tools to grind the surface of a workpiece. It is mainly used for grinding high-precision flat surfaces, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces, and other profiled surfaces of workpieces. Existing high-speed flat surface pre-grinding machines require adjustment of the height of the pre-grinding motor during operation. However, the existing adjustment method cannot guarantee the adaptability, reliability, stability, and accuracy of the pre-grinding motor's movement, causing great inconvenience to users. Therefore, a bridge gantry frame structure for a high-speed flat surface pre-grinding machine is provided. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bridge gantry frame structure for a high-speed surface pre-grinding machine, comprising a first guide post, a second guide post, and a bridge frame. The first and second guide posts are both fixed on a base. A cylinder is installed on the base between the first and second guide posts. A first linear bearing and a second linear bearing are installed on the bridge frame. A pull plate is connected between the tops of the first and second guide posts. The top of the cylinder is connected to the connector at the bottom of the bridge frame through a floating joint. The cylinder extends and retracts to push the bridge frame to move on the first and second guide posts.

[0005] As a preferred embodiment of this utility model, the first guide post and the second guide post are mounted on the base by bolts.

[0006] In a preferred embodiment of this utility model, the pull plate is fixedly connected to the first guide post by bolts and a first O-ring, and the pull plate is fixedly connected to the second guide post by bolts and a second O-ring.

[0007] In a preferred embodiment of this utility model, the pull plate is parallel to the base and perpendicular to the first guide post and the second guide post.

[0008] In a preferred embodiment of this invention, the cable tray is connected to the first guide post and the second guide post via a first linear bearing and a second linear bearing.

[0009] As a preferred embodiment of this utility model, the connector is installed on the bottom of the cable tray by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the gantry frame structure enables the pre-grinding motor of the flat pre-grinding machine to move up and down quickly and smoothly, with strong stability, and the position of the pre-grinding motor can be adjusted quickly, with strong flexibility.

[0013] 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 providing a clearer and more definite definition of the scope of protection of the present invention.

[0014] Example: Please refer to Figure 1 This utility model provides a technical solution: a bridge gantry frame structure for a high-speed flat pre-grinding machine, including a first guide post 1, a second guide post 2, and a bridge 3. The first guide post 1 and the second guide post 2 are both fixed on a base 4. A cylinder 6 is installed on the base 4 between the first guide post 1 and the second guide post 2. A first linear bearing 8 and a second linear bearing 9 are installed on the bridge 3. A pull plate 5 connects the tops of the first guide post 1 and the second guide post 2. The top of the cylinder 6 is connected to the connector 12 at the bottom of the bridge 3 via a floating joint 7. The cylinder 6 extends and retracts to push the bridge 3 to move on the first guide post 1 and the second guide post 2.

[0015] The first guide post 1 and the second guide post 2 are mounted on the base 4 by bolts.

[0016] The pull plate 5 is fixedly connected to the first guide post 1 by bolts and the first O-ring 10, and the pull plate 5 is fixedly connected to the second guide post 2 by bolts and the second O-ring 11.

[0017] The pull plate 5 is parallel to the base 4 and perpendicular to the first guide post 1 and the second guide post 2.

[0018] The cable tray 3 is connected to the first guide post 1 and the second guide post 2 via the first linear bearing 8 and the second linear bearing 9.

[0019] The connector 12 is mounted on the bottom of the cable tray 3 by bolts.

[0020] Working Principle: A gantry frame structure for a high-speed surface pre-grinding machine. The pre-grinding motor of the high-speed surface pre-grinding machine is mounted on the bridge frame 3 of the pre-grinding machine via a transition plate. The support and vertical movement of the bridge frame 3 adopt a gantry frame structure. Two high-precision guide columns are vertically mounted on the plane of the base 4 of the pre-grinding machine. The parallelism and perpendicularity of the mounting holes of the base 4 are ensured by machining. Rubber rings are designed in the mounting holes for shock absorption. Imported linear bearings are selected in the mounting holes of the bridge frame 3. The bridge frame is fitted onto the two guide columns, and a pull plate 5 at the top of the guide columns holds the two guide columns and is fixed with nuts. In this way, the support and vertical movement of the bridge frame are on a closed gantry frame on the same plane. The gantry frame on the same plane can ensure the adaptability, reliability, stability and accuracy of the bridge frame movement. A cylinder 6 is located below the bridge frame 3 to hold the bridge frame 3 in place, and the vertical movement of the bridge frame 3 is achieved by the action of the cylinder 6.

[0021] Specifically, the cylinder 6 operates to drive the telescopic rod on the cylinder 6 to extend and retract up and down, thereby pushing the bridge frame 3 and the first linear bearing 8 and the second linear bearing 9 installed on the bridge frame 3 to move on the first guide post 1 and the second guide post 2. The movement of the bridge frame 3 drives the pre-grinding motor of the high-speed flat pre-grinding machine installed on the bridge frame 3 to move up and down.

[0022] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
