Description

Technical Field

[0001] The utility model relates to the field of tool storage and retrieval management devices, specifically to an in-position state monitoring device and a tool rack for deep hole drilling and boring machine tool management in this field. Background Art

[0002] Deep hole drilling and boring machines are often used in the processing of parts such as pressure-resistant steel cylinders in oil logging systems or drill collars in measurement-while-drilling systems. The parts processed have a relatively long length, generally between 400 mm and 4000 mm. Deep hole drills and boring heads have the characteristics of a wide variety and high prices. There are many different inner hole size specifications for the parts involved in the processing, and correspondingly, various models of deep hole drills and boring heads need to be configured. After receiving the production task, production operators select the corresponding deep hole drills and boring heads according to the inner hole size. Currently, the inventory management of deep hole drills and boring heads adopts the mode of paper form collection and return, which has significant drawbacks. Inventory managers cannot real-time master the storage status of the tools and need to repeatedly check the paper forms to verify the collection and return situations; production operators may randomly place the tools on the tool rack when returning or fail to return them for a long time; the above two aspects result in time-consuming searching for deep hole drills and boring heads, low utilization efficiency, and the problem of easy loss.

[0003] The invention patent application with the patent number 201910344698.1 discloses a device for in-position detection of a firearm. Its composition is that a firearm placement part is provided on the gunstock body, and an induction tongue structural member is movably arranged on the firearm placement part; a controller and a Hall sensing component for detecting the position of the induction tongue structural member are provided inside the gunstock body, and the controller is electrically connected to the Hall sensing component. The disadvantage is that the composition of this device has relatively many structural components, is not convenient for quick disassembly and assembly, the output signal of the Hall sensor is easily interfered by the external magnetic field, and the cost is relatively high.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Embodiment 1, as Figure 1 —4 shows, this embodiment discloses an in-situ state monitoring device for tool management of a deep hole drilling and boring machine. The whole is made of engineering plastic, with a lightweight design and rapid prototyping by 3D printing. It includes a base 4, on the front of the base, tool type and model labels are pasted. A groove 6 is provided on the base. The space between the side wall of the groove and the side wall of the base is a gap. A stepped groove and two spring guide posts 14 are provided at the bottom of the groove. A travel switch 3 is installed in the stepped groove. A chute 9 is provided on each of the two opposite side walls of the groove, and the positions of the two chutes are opposite. A rectangular repair slot 10 is provided on the side wall of the base at a position opposite to the above chute. It also includes a buckle cover 1 covering the groove. An anti-slip grille is provided on the top of the buckle cover. A buckle 15 is provided on each of the two sides of the buckle cover. The two buckles are respectively buckled in the above two chutes. A boss and two spring guide posts are provided at the bottom of the buckle cover. The boss presses on the elastic piece of the above travel switch. The spring guide posts of the groove and the buckle cover are opposite in position, and a spring 2 is installed between the two opposite spring guide posts on the groove and the buckle cover.

[0025] As Figure 4 shown, a limit post 7 for protecting the elastic piece of the travel switch is provided on each of the two sides in the length direction of the stepped groove at the bottom of the groove. The stepped groove, the limit post and the spring guide post at the bottom of the groove are arranged in a row, and reinforcing ribs 8 are provided between them and between them and the side wall of the groove.

[0026] A travel switch output signal line accommodating groove is provided at the bottom of the groove. A wire passing groove is provided on the side wall of the base at a position opposite to the travel switch output signal line accommodating groove. The travel switch output signal line 5 is electrically connected to the RS485 switch quantity acquisition module through the travel switch output signal line accommodating groove and the wire passing groove. The travel switch is coated with an appropriate amount of silica gel and then installed in the stepped groove. The travel switch output signal line is welded to the travel switch, and a heat shrinkable tube for protection is provided at the welding point. An appropriate amount of silica gel is applied in the wire passing groove to fix the travel switch output signal line.

[0027] The installation process of the in-situ state monitoring device disclosed in this embodiment is as follows: First, the two springs are respectively installed in the two spring guide posts at the bottom of the groove, then the two spring guide posts of the buckle cover are respectively aligned with the tops of the two springs, and then the buckle cover is pressed down into the groove so that the buckles on both sides of the buckle cover respectively enter the chutes on the side wall of the groove, and press the buckle cover to ensure that the buckle cover can move up and down flexibly in the groove.

[0028] During maintenance, insert the thumb and index finger into the rectangular groove on the side wall of the base and hold the buckles on both sides of the cover, then squeeze inward simultaneously, and then the cover can be quickly pushed upward. When replacing the travel switch, first remove the silica gel in the wire groove of the base, and use a thin screwdriver to hold the travel switch from the receiving groove of the output signal wire of the travel switch and gently push it upward to quickly replace the travel switch and the two springs.

[0029] When there is no deep-hole cutter placed on the top of the cover, the cover is lifted by the spring, and at this time, the boss at the bottom of the cover does not press the elastic piece of the travel switch. When the production operator places the corresponding type and model of deep-hole cutter on the cover according to the label, the cover presses the spring downward under the gravity of the deep-hole cutter and presses the elastic piece of the travel switch. The travel switch senses that a deep-hole cutter is placed on the top of the cover accordingly, and sends the sensing result to the RS485 switch quantity acquisition module through the output signal wire of the travel switch, thereby realizing the real-time monitoring of the inventory status of the deep-hole cutter.

[0030] This embodiment also discloses a tool holder, as Figure 5 shown, two groups of guide rails are arranged on the top of the tool holder, and a wire protection pipe 11 is installed between adjacent guide rails. Each group of guide rails includes two opposite L-shaped adjusting supports 12. After adjusting the appropriate distance between the two L-shaped adjusting supports, clamp and fix them. Five of the above-mentioned in-position state monitoring devices 13 are installed between the two L-shaped adjusting supports of each group of guide rails. After the output signal wires of the travel switches of each in-position state monitoring device pass through the hole grooves of the L-shaped adjusting supports, they are concentrated and collected to the RS485 switch quantity acquisition module on the top of the tool holder through the adjacent wire protection pipe. The signal is then connected to the deep-hole cutter management module library in the OA office automation system through the network communication protocol, and whether the tool is in position is monitored in real time on the terminal computer.
