DETAILED DESCRIPTION

[0025] 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.

Based on the embodiments of 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.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3As shown, the device includes a mounting plate 1 and a guide sleeve 2. The guide sleeve 2 is fixedly arranged on the left and right sides of the mounting plate 1. A sliding pin 3 is slidably connected inside the guide sleeve 2. A slide plate 4 is fixedly arranged at the bottom of the slide pin 3. A first spring 5 is fixedly arranged between the top of the slide pin 3 and the guide sleeve 2. A plurality of metal sensors 6 are threadedly penetrated from left to right on the top of the mounting plate 1. A first wedge block 7 is fixedly arranged on the left side of the top of the slide plate 4. A monitoring component 8 is arranged at the bottom of the mounting plate 1. The monitoring component 8 includes a Bracket 801, a plurality of connecting pins 802 are connected from left to right at the lower end of the inner part of bracket 801, a rotating pin 803 is fixedly sleeved outside the connecting pin 802, an iron sheet 804 is fixedly provided on the top of the rotating pin 803, a gear 805 is fixedly sleeved on the outer rear end of the rotating pin 803, a sliding rod 806 is slidably connected at the lower left end of the inner part of bracket 801, a second wedge block 807 is fixedly provided at the lower left end of the outer wall of the sliding rod 806, and a rack 808 fixedly provided on the right side of the sliding rod 806 is meshed with the gear teeth of the gear 805.

[0028] The rotating pin 803 is made of rubber, and the plurality of metal sensors 6 and the plurality of rotating pins 803 are designed to correspond to each other one by one. First, the mounting plate 1 is connected to the tail end of the ram, and then the metal sensor 6 is connected to the drive system of the machine tool through a wire. When in use, the drive system of the machine tool controls the ram to drive the mounting plate 1 together with the slide plate 4 to move inside the inner cavity of the workpiece. In addition, the metal sensor 6 detects the iron sheet 804, so that the drive system of the machine tool is in a normal operating state. When the slide plate 4 contacts the cavity wall of the inner cavity, the slide plate 4 drives the sliding pin 3 to move along the direction of the mounting plate 1, and the first spring 5 is deformed. At the same time, the slide plate 4 drives the first wedge block 7 to squeeze the second wedge block 807 together with the slide bar 806 to drive the rack 808 to control the gear 805, the connecting pin 802 and the rotating pin 803 to rotate, so that the rotating pin 803 drives the iron sheet 804 and the monitoring end at the bottom of the metal sensor 6 to be in a misaligned state. When the metal sensor 6 does not detect the iron sheet 804, the drive system of the machine tool stops running to prevent the ram from hitting the cavity wall of the inner cavity of the workpiece.

[0029] Example 2

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the front cross-section of the bracket 801 is U-shaped, the guide hole 9 integrally provided at the bottom end of the bracket 801 is a through hole, a baffle 10 made of rubber is fixed at the upper end of the bracket 801, and clearance holes 11 are integrally provided at the upper and lower ends of the baffle 10 from left to right, the clearance holes 11 are through holes, and the clearance holes 11 are in a one-to-one correspondence with the metal sensor 6 and the turn pin 803, a cavity 12 is integrally provided inside the baffle 10, the interior of the cavity 12 is in a connected design state with the interior of the clearance hole 11, a blocking plate 13 is slidably connected inside the cavity 12, the blocking plate 13 is made of rubber, and the bottom left side of the blocking plate 13 A connecting block 14 is fixedly provided, and the bottom of the connecting block 14 is fixedly connected to the top of the sliding rod 806. Avoidance holes 15 are integrally provided inside the blocking plate 13 from left to right. The avoidance holes 15 are through-holes, and the top cross-section of the avoidance holes 15 is equal to the top cross-section of the avoidance holes 11. The mounting hole 16 integrally provided on the left side of the bottom end of the baffle 10 is a through-hole, and the mounting hole 16 is sleeved on the outside of the connecting block 14. Guide grooves 17 are integrally provided on the left and right sides of the guide sleeve 2, and a slider 18 is slidably connected inside the guide groove 17. The inner side of the slider 18 is fixedly connected to the outer wall of the sliding pin 3. A second spring 19 is fixedly provided between the right side of the rack 808 and the bracket 801.

[0031] According to the operation method in Example 1, when the slide bar 806 drives the rack 808 to control the gear 805 to rotate, the slide bar 806 simultaneously drives the connecting block 14 and the blocking plate 13 to move to the right along the direction of the baffle 10, so that the blocking plate 13 puts the avoidance hole 15 and the clearance hole 11 in a mutually misaligned state, that is, the blocking plate 13 blocks the bottom of the metal sensor 6, preventing the metal sensor 6 from mistakenly detecting the rack 808 and being mistakenly turned on, thereby ensuring the stability of the metal sensor 6 controlling the machine tool drive system. In addition, the design of the slider 18 slidingly connected inside the guide groove 17 can prevent the first spring 5 from pushing the sliding pin 3 out of the guide sleeve 2 when it rebounds. When the rack 808 moves along the right side of the bracket 801, the second spring 19 is deformed, and the rack 808 together with the gear 805, the connecting pin 802, the rotating pin 803 and the iron sheet 804 can be reset by the rebound force of the second spring 19.
