Abstract

The utility model discloses a tool rest fastening detection mechanism, which comprises a servo motor (1), a fastening signal lug (4), a fastening signal push rod (5), a fastening signal ring (6), a proximity switch (7) and a main shaft (8). A first gear (2) is fitted on an output shaft (1-1) of the servo motor (1); a second gear (3) is fitted on the main shaft (8); the second gear (3) is meshed with the first gear (2); the fastening signal lug (4) is fixedly connected with the second gear (3); the fastening signal lug (4) leans against the front end of the fastening signal push rod (5); the fastening signal ring (6) is fitted on the main shaft (8) and connected with the rear end of the fastening signal push rod (5); and the proximity switch (7) is arranged in the periphery of the fastening signal ring (6). The tool rest fastening detection mechanism disclosed by the utility model can well detect whether the tool rest is fastened.

Description

Knife rest locking testing agency

Technical field

The utility model relates to a kind of knife rest and locks testing agency, is used for the knife rest of lathe.

Background technology

At present, the locking of lathe cutter saddle utilization locking fluted disc, but there is a general defective in this equipment; Have no checkout gear to detect when locking exactly, this will cause because lathe cutter saddle is not locked, and lathe is work just; Thereby make processing parts scrap, or even hit the phenomenon of cutter.

Summary of the invention

The purpose of the utility model provides and a kind ofly can detect the knife rest locking testing agency whether knife rest lock.

The technical scheme that realizes the utility model purpose is: a kind of knife rest is locked testing agency; It comprises servomotor, locking signal projection, locking signal push rod, locking signal roundel, near switch and main shaft, be set with first gear on the output shaft of servomotor, be set with second gear on the main shaft; This second gear and first gears engaged; Locking signal projection is fixedly connected with second gear, and locking signal projection contacts with the front end of locking signal push rod, and the locking signal roundel is sleeved on the main shaft; This locking signal roundel is connected with the rear end of locking signal push rod, is arranged on the periphery of locking signal roundel near switch.

Further, locking signal projection contacts or plane contact with the front end inclined-plane of locking signal push rod.

After having adopted technique scheme, when the flying knife tower was worked automatically, servomotor rotated; Drive first gear and rotate, second gear also and then rotates, and is connected the also and then rotation of locking signal projection on second gear; Cause locking the signal projection and contact the complanation contact with locking signal push rod by the inclined-plane, locking signal push rod moves backward, promotes to move behind the locking signal roundel; After move on to and be positioned near below the switch time, receiving key is just received the locking signal, and its signal is sent to locking device; Lock control, so just accomplished the course of work whether whole detection knife rest locks, avoided this because lathe cutter saddle is not locked; Lathe is work just, thereby cause processing parts to scrap, or even hit the phenomenon of cutter.

Description of drawings

Fig. 1 is the scheme of installation of the utility model;

Fig. 2 is that the inclined-plane of locking signal projection and locking signal push rod in the utility model contacts sketch map;

Fig. 3 is a locking signal projection and the plane contact sketch map of locking the signal push rod in the utility model.

The specific embodiment

For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,

As shown in Figure 1, a kind of knife rest locking testing agency, it comprises servomotor 1, locking signal projection 4, locking signal push rod 5, locking signal roundel 6, near switch 7 and main shaft 8; Be set with first gear 2 on the output shaft 1-1 of servomotor 1; Be set with second gear 3 on the main shaft 8, this

second gear

3 and 2 engagements of first gear, locking signal projection 4 is fixedly connected with second gear 3 through screw; Locking signal projection 4 contacts with the front end of locking signal push rod 5; Locking signal roundel 6 is sleeved on the main shaft 8, and this locking signal roundel 6 is connected with the rear end of locking signal push rod 5, is arranged on the periphery of locking signal roundel 6 near switch 7.

Like Fig. 2, shown in 3, locking signal projection 4 contacts or plane contact with 5 front end inclined-planes of locking signal push rod.

The operation principle of the utility model is following:

When the flying knife tower was worked automatically, servomotor 1 rotated, and drove first gear 2 and rotated; Second gear 3 also and then rotates, and is connected the also and then rotation of locking signal projection 4 on second gear 3, causes locking signal projection 4 and contacts the complanation contact with locking signal push rod 5 by the inclined-plane; Locking signal push rod 5 moves backward; Promote to move behind the locking signal roundel 6, after move on to and be positioned near below the switch 7 time, receiving key 7 is just received the locking signal; Its signal is sent to locking device, lock control.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
