Description

Technical Field

[0001] This utility model relates to a fully hydraulic tailstock specifically for laser cladding machine tools. Background Technology

[0002] The tailstock of a laser cladding machine requires lateral adjustment to match the length of the shaft-like workpiece. After being adjusted to the appropriate position, it is then tightened using a center. Compared to manually tightened mechanical structures, the hydraulic buffering of a cladding machine tailstock using a hydraulic telescopic center can offset the expansion of the workpiece during cladding, and it is also easier to introduce automated control, making it an advantageous configuration. In contrast, during the initial preparation work, the overall movement of the tailstock is generally still a mechanical structure: driven by gears, racks, or chains, with the power mechanism typically being a motor with a reducer; after reaching the appropriate position, it is then manually tightened with screws. The three actions—center movement, tailstock lateral movement, and tailstock locking—involve three different power sources and three different actions, making it relatively complex and not simple enough.

Using a single hydraulic station, the operations do not interfere with each other. The hydraulic station is integrated inside the base 100, resulting in a compact size and neat appearance.

[0068] This utility model provides a fully hydraulic tailstock specifically for laser cladding machine tools. Its sole power source is a hydraulic station, which consists of an oil tank 101, an oil pump motor 102, an oil pump 103, a valve block assembly 104, and corresponding pipelines. The hydraulic station has three outputs (i.e., it has three independent hydraulic output circuits, each of which can independently control its pressure, flow rate, and direction), each connected to three different sets of hydraulic cylinders, as detailed below:

[0069] The first hydraulic output circuit, namely the first hydraulic cylinder 210 responsible for the movement of the tip 205, is fixedly mounted on the top of the base 100. The piston rod 214 of the tip cylinder is connected to the tip sleeve 204. The tip sleeve 204 is located in the through hole 201 in the top seat 200. The tip cylinder flange 212 at the left end of the tip cylinder housing 211 is fixedly mounted on the right side wall of the sealing cover 202 on the right side of the top seat body 200. The tip sleeve 204 can cooperate with the tip 205. In this way, the piston rod 214 of the tip cylinder can control the left and right movement of the tip sleeve 204, that is, the tip 205.

[0070] The second hydraulic output circuit connects to the cylinder that moves the tailstock body (base 100) laterally, specifically the tailstock cylinder 106. This tailstock cylinder 106 can be a multi-stage cylinder, installed and fixed at the bottom of the hydraulic station inside the base housing. The piston rod of the tailstock cylinder is fixed to the bed 300 of the laser cladding machine. Pressurizing the tailstock cylinder 106 causes the base 100 (tailstock body) to move as a whole, adjusting it to the appropriate working position. Furthermore, a suitable multi-stage cylinder can be selected based on the bed 300 of the laser cladding machine and the length of the workpiece. The extension and retraction stroke of the multi-stage cylinder can generally meet the stroke requirements of the tailstock body.

[0071] The third hydraulic output circuit is responsible for connecting the cylinder that locks the tailstock body. This cylinder can be a series of multiple short-stroke cylinders, specifically: the multiple short-stroke cylinders include a first short-stroke cylinder 151 and a second short-stroke cylinder 152. Since the bottom of the base 100 is composed of a first inclined plate 113 and a second inclined plate 114, the first short-stroke cylinder 151 is set on the first inclined plate 113, and the second short-stroke cylinder 152 is set on the second inclined plate 114. Meanwhile, for smooth operation and safety, a locking mechanism is respectively set on the left and right sides of the support plate 105 at the bottom of the base housing on the base 100. Each locking mechanism includes a first locking component and a second locking component. The first locking component is set on the first inclined plate 113 and includes the first short-stroke cylinder 151; the second locking component is set on the second inclined plate 114 and includes the second short-stroke cylinder 152.

[0072] The first locking assembly includes a first wedge 121, a first locking plate 131, a first connecting bolt 141, and a first short-stroke cylinder 151. The first short-stroke cylinder 151 is fixedly mounted on the first inclined plate 113. The first locking plate 131 cooperates with the first wedge 121. The first wedge 121, the first locking plate 131, and the bed 300 are connected by the first connecting bolt 141. When the piston rod 161 of the first short-stroke cylinder 151 extends outward, it pushes the first wedge 121 to move. The first locking plate 131 is pushed open by the first wedge 121. Since the first fastening bolt 141 passes through the bed 300 in sequence... The first inclined plate 113, the first wedge 121, and the first locking plate 131 are securely locked together by the thrust generated by the first wedge 121, thereby fastening the first inclined plate 113, i.e. the tailstock body, to the bed 300. When the piston rod 161 of the first short-stroke cylinder 151 retracts, the first wedge 121 is pulled out from between the first locking plate 131 and the tailstock body, i.e. the first inclined plate 113, and the gap increases. The first fastening bolt 141 droops down, so that the first inclined plate 113, i.e. the tailstock body, is separated from the bed 300 and the tailstock body can move along the guide rail on the bed 300. Since the mating surfaces of the first wedge 121 and the first locking plate 131 are inclined, the friction between them and the locking force of the first fastening bolt 141 are not in the same direction, but in a nearly perpendicular cross state. Thus, even if the hydraulic station stops pressurizing the first short-stroke cylinder 151, the first fastening bolt 141 will not loosen due to the friction between the first wedge 121 and the first locking plate 131, and the tailstock body can still be locked.

[0073] The second locking assembly includes a second wedge 122, a second locking plate 132, a second connecting bolt 142, and a second short-stroke hydraulic cylinder 152. The second short-stroke hydraulic cylinder 152 is fixedly mounted on the second inclined plate 114. The second locking plate 132 cooperates with the second wedge 122, and the second wedge 122, the second locking plate 132, and the bed 300 are connected by the second connecting bolt 142. Since the second inclined plate 114 has a large surface area, the second locking assembly also includes a third wedge 123, a third locking plate 133, a third connecting bolt 143, and a connecting column 163. The second short-stroke hydraulic cylinder 152 is slidably mounted on the second inclined plate 114. On plate 114, that is, the second short-stroke cylinder 152 can slide along the width direction of the upper surface of the second inclined plate 114 under the movement of the piston rod 162 of the second short-stroke cylinder, and the second wedge 122 and the third wedge 123 are respectively arranged on the front and rear sides of the second short-stroke cylinder 152; the second locking plate 132 cooperates with the second wedge 122, and the second wedge 122, the second locking plate 132 and the bed 300 are connected by the second connecting bolt 142; and the third locking plate 133 cooperates with the third wedge 123, and the third locking plate 133 and the bed 300 are connected by the third connecting bolt 143.

[0074] When the piston rod 162 of the second short-stroke cylinder 152 extends outward, it pushes the second wedge 122 and the third wedge 123 to move. The second through locking plate 132 is pushed open by the second wedge 122. Since the second fastening bolt 142 passes through the bed 300, the second inclined plate 114, the second wedge 122 and the second locking plate 132 in sequence, the thrust generated by the second wedge 122 firmly locks these components. At the same time, since the third fastening bolt 143 passes through the bed 300, the second inclined plate 114, the third wedge 123 and the third locking plate 133 in sequence, the thrust generated by the third wedge 123 firmly locks these components, thereby firmly connecting the second inclined plate 114, i.e. the tailstock body, to the bed 300.

[0075] When the piston rod 162 of the second short-stroke cylinder 152 retracts, the second wedge 122 is pulled out from between the second locking plate 131 and the second inclined plate 114. At the same time, the third wedge 123 is pulled out from between the third locking plate 133 and the second inclined plate 114, the gap increases, and the second fastening bolt 142 and the third fastening bolt 143 both droop down. As a result, the second inclined plate 114, that is, the tailstock body, is separated from the bed 300, and the tailstock body can move along the guide rail direction on the bed 300.
