Description

Technical Field

[0001] This invention belongs to the field of machine tool equipment technology and relates to an installation method for equipment with a left and right inclined bed structure. Background Technology

[0002] Slant bed is a common structure in machine tool design, especially widely used in lathes, milling machines and other high-precision machining equipment.

[0003] Patent CN216000229U discloses an orientation adjustment device for wind turbine blade processing, including a base, a first orientation adjustment component, and a load-bearing component. The first orientation adjustment component includes two horizontally symmetrically arranged adjustment seats. The adjustment seats are slidably mounted on the base. The load-bearing component includes two horizontally symmetrically arranged support seats. The two support seats are correspondingly mounted on the two adjustment seats, with the upper end of the adjustment seat slidably connected to the lower end of the corresponding support seat. The two support seats can move in the same direction in the left-right direction or move up and down in the vertical direction through the adjustment seats. The essence of the solution is to use a left-right slant bed structure, with movement and adjustment via a wedge drive mechanism. However, the left and right slant beds are rigidly connected. While this connection method ensures the overall rigidity of the machine tool, it also brings some problems. Due to the large contact surface size of the left and right slant beds, it is difficult to guarantee parallelism and perpendicularity during manufacturing, resulting in slight parallelism errors during installation. These errors will gradually appear in actual use, and the non-parallelism of the left and right slant beds will cause uneven loads on the linear guide rail and slider during operation. This uneven load will accelerate the wear of the guide rail and slider, and may even cause deformation of the guide rail and damage to the slider, thereby affecting the machining accuracy and service life of the machine tool. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to solve the above problems and provide an installation method for a device with a left and right inclined bed structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for installing a machine tool with a left and right slant bed structure is disclosed. The machine tool includes a base, a wedge drive mechanism, a left slant bed, and a right slant bed. The left and right slant beds are each supported on the base by their respective wedge drive mechanisms. A flexible connection device is used to connect the left and right slant beds. During installation, the left and right slant beds are first allowed to automatically engage with their respective wedge drive mechanisms under gravity. After the left and right slant beds are placed parallel to each other, they are then locked together using the flexible connection device. This method solves the problem of non-parallelism caused by machining errors when the left and right slant beds are rigidly connected, which can lead to damage to the linear guide rails and sliders.

[0007] Furthermore, the flexible connection device includes a connecting rod, a spherical washer, and a nut. The connecting rod is threaded, the spherical washer is fitted onto the connecting rod, and the nut is connected to the connecting rod via the thread. Each of the left and right slant beds has a connecting seat on one side facing each other, with a connecting hole on the connecting seat. One end of the connecting rod passes through the connecting hole, and the connecting rod and the connecting hole are in a clearance fit. Spherical washers are provided on both sides of the connecting hole, and the spherical washers are locked and pressed against one side of the connecting hole by a nut on one side, thus fixing the connecting rod to the connecting seat. When the left and right slant beds are not parallel, the connecting seat swings at a certain angle through the spherical washer, causing relative displacement between the left and right slant beds. Each of the left and right slant beds then engages with the wedge drive mechanism. The spherical washer provides relative freedom of movement between the left and right slant beds, automatically compensating for any errors and keeping them parallel.

[0008] Furthermore, the gap between the connecting rod and the connecting hole is 1% to 3% of the diameter of the connecting hole.

[0009] Furthermore, the wedge drive mechanism includes a power unit, a lead screw, and a wedge support; both the upper and lower sides of the wedge support are provided with linear guide rails, and the left and right slant beds are slidably connected to the wedge support via the linear guide rails, and the wedge support is slidably connected to the base via the linear guide rails; the wedge support is mounted on the lead screw, and the power unit is connected to the lead screw, which drives the wedge support to move along the linear guide rails, thereby driving the left and right slant beds to move left and right or vertically up and down synchronously.

[0010] Furthermore, the left slant bed and the right slant bed are connected by one or more flexible connecting devices.

[0011] The beneficial effects of this invention are as follows:

[0012] This invention employs a flexible connecting device, allowing for relative movement between the left and right slant beds. When the left and right slant beds are not parallel, the connecting seat uses spherical washers to swing at a certain angle, automatically compensating for the error and keeping them parallel. This effectively avoids the problem of uneven load distribution and damage to the linear guide slider caused by machining errors leading to non-parallel installation of the left and right slant beds, thus extending the service life of the machine tool.

[0022] Please see Figures 1-3 This is an installation method for a machine tool with a left and right slant bed structure. The machine tool includes a base 5, a wedge drive mechanism 4, a left slant bed 1, and a right slant bed 3. The left slant bed 1 and the right slant bed 3 are respectively supported on the base 5 by the wedge drive mechanism 4 below them, and the left slant bed 1 and the right slant bed 3 are connected by a flexible connection device 2.

[0023] The flexible connection device 2 includes a connecting rod 21, a spherical washer, and a nut. The connecting rod 21 is threaded, the spherical washer is fitted onto the connecting rod 21, and the nut is connected to the connecting rod 21 by the thread. The left slant bed 1 and the right slant bed 3 are each provided with a connecting seat 11 on their opposite sides, and the connecting seat 11 is provided with a connecting hole.

[0024] During installation, the left slant bed 1 and the right slant bed 3 are first automatically engaged with the wedge drive mechanism 4 below them under the action of gravity. After the left slant bed 1 and the right slant bed 3 are placed in parallel, the left slant bed 1 and the right slant bed 3 are then locked together by the flexible connecting device 2.

[0025] The left slant bed 1 and the right slant bed 3 are connected to the flexible connecting device 2 in the same way, so the left slant bed 1 will be used as an example for detailed explanation: The left end of the connecting rod 21 passes through the connecting hole, and the connecting rod 21 and the connecting hole are in clearance fit; spherical washers 23 and 24 are respectively provided on both sides of the connecting hole. The spherical washer 23 is pressed against the right side of the connecting hole by a nut 22 on one side, and the spherical washer 24 is pressed against the left side of the connecting hole by a nut 25 on one side. When the left slant bed 1 and the right slant bed 3 are installed, the left slant bed 1 is detected. When the left slant bed 1 and the right slant bed 3 are not parallel, the connecting seat 11 swings at a certain angle through the spherical washer, and the left slant bed 1 and the right slant bed 3 are relatively displaced. Under the action of gravity, they respectively adhere to the wedge drive mechanism 4. First, the left slant bed 1 and the right slant bed 3 are automatically adhered to the wedge drive mechanism 4 below them under the action of gravity, so that the left slant bed 1 and the right slant bed 3 remain parallel. After the left slant bed 1 and the right slant bed 3 are placed parallel, the connecting seat 11 and the connecting rod 21 are fixedly connected through the nuts 22 and 25.

[0026] The gap between the connecting rod 21 and the connecting hole is 1% to 3% of the diameter of the connecting hole, ensuring that there is sufficient room for movement between the connecting rod 21 and the connecting seat 11.

[0027] The wedge drive mechanism 4 in this embodiment includes a power unit 8, a lead screw 7, and a wedge support 6. Linear guide rails are provided on both the upper and lower sides of the wedge support 6. The left slant bed 1 and the right slant bed 3 are slidably connected to the wedge support 6 via linear guide rails 9, and the wedge support 6 is slidably connected to the base 5 via linear guide rails 10. The wedge support 6 is mounted on the lead screw 7, and the power unit 8 is connected to the lead screw 7. The lead screw 7 drives the wedge support 6 to move along the linear guide rails, thereby driving the left slant bed 1 and the right slant bed 3 to move left and right or vertically up and down synchronously.

[0028] In some embodiments, the left inclined bed 1 and the right inclined bed 3 are connected by one or more flexible connecting devices 2, the number of which is determined according to the width of the bed.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
