Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a support plate locking structure. Background Art

[0002] In order to meet the different use requirements of glass, it is necessary to grind the edges of the glass. The edge grinding of glass is usually done by grinding the side of the glass with the help of the grinding wheel in the edge grinding machine. Before grinding, the grinding wheel in the edge grinding machine needs to adjust the grinding wheel reference. During the adjustment of the grinding wheel reference, when the grinding wheel moves to the preset reference position, the support plate needs to be locked through the locking device so that the grinding wheel is in the reference position.

[0003] At present, the locking structures of the pallet are as follows: 1. Threaded locking. This locking method cannot be locked automatically and must be adjusted manually frequently, which is time-consuming and labor-intensive. 2. Molded locking cylinder locking. This locking method has the defects of high cost and large axial clearance after locking. 3. Clamp locking installed on the pallet guide rail. This locking method has the defects of high cost and troublesome maintenance. 4. Rubber sleeve locking. This locking method has the defects of low locking force and easy aging of rubber.

The pallet is arranged above the lower box, and the pallet forms a linear sliding connection with the lower box via a sliding assembly. The main cylinder is connected to the pallet and is used to drive the pallet to slide along the upper surface of the lower box. The locking cylinder is installed between the top end surface of the lower box and the bottom end surface of the pallet, and the locking block is fixedly installed on the piston rod of the locking cylinder. The bottom end surface of the pallet is formed with a groove that is tightly matched with the locking block.

[0007] Furthermore, the locking block and the slot are respectively tapered structures that are narrow at the top and wide at the bottom.

[0008] Furthermore, a connecting flange is fixedly mounted on one side of the lower box body adjacent to the main cylinder, the main cylinder is fixedly mounted on the connecting flange, and the main cylinder is fixedly connected to the support plate via a connecting shaft to drive the support plate to move linearly back and forth.

[0009] Furthermore, a nut is fixedly mounted on one end of the connecting shaft away from the main cylinder, and the bottom end of the support plate is fixedly connected to the nut.

[0010] Furthermore, the sliding assembly includes a pair of linear guide rails fixedly mounted on the upper end surface of the lower box body and a pair of sliding blocks fixedly mounted on the bottom end surface of the support plate, and the support plate is slidably mounted on the linear guide rails via the sliding blocks.

[0011] The beneficial effects of the utility model are as follows: a locking cylinder is arranged between the support plate and the lower box body, a locking block is installed on the locking cylinder, and a slot that is tightly matched with the locking block is formed on the bottom end surface of the support plate. When in use, the locking cylinder can be used to drive the locking block on it to move upward and tightly match with the slot to fix the position of the support plate.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] See attached Figure 1 To Attachment Figure 3 As shown, this embodiment provides a support plate locking structure 100, which includes a support plate 2, a lower box body 1, a main cylinder 3, a locking cylinder 5 and a locking block 6.

[0020] The support plate 2 is arranged directly above the lower box body 1, and the support plate 2 is slidably connected to the lower box body 1 through the provided sliding assembly 4, that is, the support plate 2 can reciprocate linearly relative to the length direction of the lower box body 1. Figure 3 As shown, specifically, the sliding assembly 4 includes a pair of linear guide rails 42 and a pair of sliders 41. The pair of linear guide rails 42 are fixedly installed on the top surface of the lower box body 1 in parallel with the length direction of the lower box body 1, and the pair of sliders 41 are correspondingly fixedly installed on the bottom surface of the support plate 2. The support plate 2 forms a sliding connection with the lower box body 1 through the above-mentioned slide rails and the linear guide rails 42.

[0021] Continue to refer to the attached Figure 1 and attached Figure 3 As shown, a connecting flange 7 is fixedly installed at one end surface of the lower box body 1 near the main cylinder 3, and the main cylinder 3 is fixedly installed on the connecting flange 7. One end of the piston rod of the main cylinder 3 is fixedly connected to a connecting shaft 9, and the other end of the connecting shaft 9 extends to the bottom end surface of the support plate 2. A nut 8 is fixedly installed at one end of the connecting shaft 9 located at the bottom end surface of the support plate 2, and the bottom end of the support plate 2 is fixedly connected to the nut 8, so that the main cylinder 3 can drive the support plate 2 to move synchronously by driving the connecting shaft 9 to move.

[0022] See attached Figure 2 And attached Figure 4 As shown, the locking cylinder 5 is fixedly mounted on the top surface of the lower box body 1, the locking block 6 is fixedly mounted on the piston rod of the locking cylinder 5, the locking block 6 is arranged between the support plate 2 and the lower box body 1, and a clamping groove 21 for clamping with the locking block 6 is formed on the bottom surface of the support plate 2. In order to ensure the clamping effect, the locking block 6 and the clamping groove 21 adopt a conical shape structure that is narrow at the top and wide at the bottom.

[0023] In order to better understand the support plate locking structure in this embodiment, the working principle thereof is briefly described below:

[0024] When it is necessary to adjust the grinding wheel reference on the edge grinding machine, the locking cylinder 5 is in the initial state, at which time the locking block 6 and the slot 21 at the bottom end surface of the support plate 2 are disengaged, and the main cylinder 3 drives the support plate 2 to move forward through the connecting shaft 9. When the grinding wheel reaches the preset reference position, the locking cylinder 5 is actuated to push the locking block 6 installed thereon upward, and engage with the slot 21 at the bottom end surface of the support plate 2 to achieve fixed locking of the position of the support plate 2.
