Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a tailstock in-place detection device for a lathe. Background Art

[0002] During machine tool processing, the workpiece is generally fixed by the chuck of the machine tool, and the tool group is driven to feed by manually shaking the handle of the tailstock, which is inconvenient to use. In order to solve this problem, the existing technology, such as the Chinese utility model patent with application number 201922252876.6, is a self-feeding horizontal lathe. A travel switch is installed on the machine tool, and the tailstock is driven to slide by a screw rod. When the tailstock slides, it touches the travel switch to cut off the power supply of the screw rod.

[0003] However, the principle of the travel switch is to achieve the closing of two breakpoints by the swing of the swing arm, and the accuracy is relatively poor. In addition, the travel switch is inserted into different travel switch installation slots, so that the travel switch is set at different positions. In this way, because the position and number of the travel switch installation slots are fixed, the position of the travel switch cannot be adjusted more accurately.

[0004] In view of this, we propose a tailstock in-place detection device for a lathe to solve the above problems. Utility Model Content

[0005] The utility model provides a tailstock in-place detection device for a lathe, which can control the stopping position of the tailstock more accurately during processing and is more convenient to use.

[0006] The utility model provides the following technical solutions: a tailstock in-position detection device for a lathe, comprising a single-shot photoelectric switch, which is fixedly arranged on the side of a sliding tailstock of a machine tool; a light-receiving and reflecting device, which comprises a shell fixed on the side of the machine tool and a reflective plate slidably connected to the shell; a reflective plate quick positioning block, which is slidably connected to the shell, and the reflective plate quick positioning block is slidably arranged below the reflective plate and is detachably connected to the reflective plate.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. The utility model uses a single-shot photoelectric switch to replace the existing travel switch when the sliding tailstock is in place. When the sliding tailstock is in place, the light emitted by the single-shot photoelectric switch is quickly reflected by the reflector, so that the single-shot photoelectric switch quickly cuts off the power supply with the sliding tailstock, and the accuracy is higher;

[0009] 2. The single-shot photoelectric switch of the utility model is slidably arranged on the side of the machine tool through the outer shell, and can be adjusted according to the length of the workpiece and the processing depth. A reflector quick positioning block is also slidably arranged on the outer shell. When processing some common workpieces, the reflector can be quickly positioned through the reflector quick positioning block, so as to quickly determine the stop position when the sliding tailstock slides, which is convenient to use.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3 The utility model provides a tailstock in-position detection device for a lathe, comprising a single-shot photoelectric switch 10 fixedly arranged on a sliding tailstock 30 of a machine tool 20 and a receiving and reflecting device 40 installed on the side of the machine tool 20. The single-shot photoelectric switch 10 is electrically connected to a power source that drives the sliding tailstock 30 to slide on the machine tool 20. During operation, the sliding tailstock 30 slides and drives the tool group to move to drill a workpiece fixed on the machine tool 20. When the single-shot photoelectric switch 10 slides to the receiving and reflecting device 40, the light emitted by the single-shot photoelectric switch 10 is returned, so that the single-shot photoelectric switch 10 automatically cuts off the power source that drives the sliding tailstock 30 to slide, and stops drilling. By setting the photoelectric switch, the power source can be quickly cut off when the sliding tailstock 30 is in position, and the continued movement of the sliding tailstock 3 is stopped. The photoelectric switch is slidably arranged on the side of the machine tool 20, so that the stop position of the sliding tailstock 3 can be adjusted more conveniently, and compared with the prior art, it is more accurate.

[0015] Specifically, in this embodiment, the reflective receiving device 40 includes a shell 41 fixed to the side of the machine tool 20, the shell 41 is fixed with a first slide rail 410, an adjusting screw 50 is rotatably provided in the first slide rail 410, a sliding block 420 is slidably provided in the first slide rail 410, a reflective plate 42 is fixed to the upper end of the sliding block 420, the adjusting screw 50 and the sliding block 420 are threadedly connected, and the staff drives the sliding block 420 to slide by manually rotating the adjusting screw 50 to adjust the position of the reflective plate 42, and a second slide rail 411 is fixed to the lower end of the first slide rail 410, and at least two reflective plate quick positioning blocks 43 are slidably provided in the second slide rail 411 The reflector quick positioning block 43 is detachably connected to the sliding block 420. Through the setting of the reflector quick positioning block 43, the position of the reflector quick positioning block 43 is set before use. When drilling, the sliding block 420 can be quickly moved to the position of the reflector quick positioning block 43 to quickly position the reflector 42. For example, when in use, the common workpiece lengths are 0.5m and 1m, then the reflector quick positioning block 43 can be moved to the positions corresponding to 0.5m and 1m respectively. In this way, when processing the corresponding workpiece, the reflector 42 can be quickly moved to the position of the reflector quick positioning block 43, which is more convenient to use.

[0016] Please refer to Figure 2 In this embodiment, a damping pad 412 is fixed to the inner side of the second slide rail 411, and the inner surface of the reflector quick positioning block 43 is in close contact with the surface of the damping pad 412. There is a large friction between the damping pad 412 and the reflector quick positioning block 43, which is convenient for limiting the reflector quick positioning block 43.

[0017] Please refer to Figure 3 In this embodiment, an opening 413 is formed between the first slide rail 410 and the second slide rail 411, a fixing bolt 60 is threadedly connected to the reflector quick positioning block 43, and a fixing groove 421 is formed at the lower end of the sliding block 420. When the sliding block 420 at the lower end of the reflector 42 is connected to the reflector quick positioning block 43, the fixing bolt 60 is rotated so that the upper end of the fixing bolt 60 passes through the opening 413 and is inserted into the fixing groove 421, so that the reflector 42 can be quickly limited.

[0018] The height of the reflector 42 is not less than that of the single-shot photoelectric switch 10 .

[0019] Please refer to Figure 3 In this embodiment, a scale 70 is provided on the surface of the housing 41 to facilitate adjusting the position of the reflector quick positioning block 43 or the reflector 42 according to the scale 70 .

[0020] The specific implementation of this embodiment is described in detail below. When in use, the staff first sets the position of the reflector quick positioning block 43 according to the workpieces that are often processed. When processing uncommon workpieces, the workpiece is fixed on the chuck of the machine tool 20, and the position of the reflector 42 is adjusted by rotating the adjusting screw 50 to drive the sliding block 420 to slide, and then the sliding tailstock 30 drives the knife group to move to process the workpiece. When the single-shot photoelectric switch 10 slides to the position of the reflector 42, the light emitted by the single-shot photoelectric switch 10 is returned by the reflector 42, so that the single-shot photoelectric switch 10 automatically cuts off the power supply that drives the sliding tailstock 30 to slide. When processing common workpieces, since the position of the reflector quick positioning block 43 has been fixed, it is only necessary to quickly slide the reflector 42, and the reflector 42 can be quickly positioned by the fixing bolt 60.
