Description

Technical Field

[0001] This utility model belongs to the field of grooving machine technology, and specifically relates to a tool retraction mechanism for a grooving machine. Background Technology

[0002] Chinese Patent CN102513601B discloses a vertical keyway broaching machine, including a slide rail, a tool holder, a feed rod, an apron, a first spring, a second spring, a hydraulic piston rod, and a feed drive device. The slide rails are parallel to each other and fixed to the machine tool; the apron is located in the middle of the slide rails and can slide along them; the hydraulic piston rod, driven by hydraulic pressure, can move the apron up and down; a servo motor is mounted on the apron, which can drive a lead screw to achieve the up and down movement of the feed rod relative to the apron; the tool holder is connected to the apron and can rotate relative to the apron and also move slightly up and down; a first spring is horizontally connected to the tool holder and the apron; a second spring is vertically connected to the tool holder and the apron.

[0003] The above technical solution has the following drawbacks: During the processing of the vertical keyway broaching machine, since the tool bar must be inserted into the material for cutting, and the tool bar cannot avoid the material, the material can only be inserted from the end of the tool bar along its axis when loading. This loading method has a long operating stroke, poor operation convenience, and requires a lot of surrounding space. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a tool retraction mechanism for a grooving machine. The technical problem to be solved by this utility model is: how to reduce space occupation.

[0005] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: a tool retraction mechanism for a grooving machine, comprising a base, a tool bar, and a blade, wherein the tool bar supports the blade, a tool puller is slidably disposed on the base, the tool puller is connected to the blade, a driving member is disposed on the base for driving the tool puller to slide, a fixed seat is slidably disposed on the base, the fixed seat is connected to the tool bar, and the tool puller and the fixed seat can be in a relatively fixed state or a separated state. When the tool puller and the fixed seat are in a relatively fixed state, the driving member drives the tool puller to slide, and the tool puller drives the blade, the fixed seat, and the tool bar to slide. When the tool puller and the fixed seat are in a separated state, the driving member drives the tool puller to slide, and the tool puller drives the blade to slide.

[0006] In the above-mentioned grooving machine retraction mechanism, the fixed base is provided with a positioning pin and the puller base is provided with a positioning sleeve. When the positioning pin is inserted into the positioning sleeve, the puller base and the fixed base are in a fixed state. When the positioning pin is disengaged from the positioning sleeve, the puller base and the fixed base are in a separated state.

[0007] In the above-mentioned grooving machine retraction mechanism, the fixed seat and the base can remain relatively fixed, so that when the driving member drives the puller seat to slide, the positioning pin disengages from the positioning sleeve.

[0008] In the above-mentioned grooving machine tool retraction mechanism, a baffle is installed on the base, a lock seat and a locking element are provided on the baffle, and a locking pin is provided on the fixed seat. The locking element enables the locking pin and the lock seat to be in a relatively fixed state or in a relatively movable state.

[0009] In the aforementioned grooving machine tool retraction mechanism, the locking component includes a driving component and a locking tongue. The driving component is mounted on the baffle, and the locking tongue is slidably disposed within the lock seat. The output end of the driving component is connected to the locking tongue. The driving component is used to drive the locking tongue to move, causing the locking tongue to pass through or disengage from the locking pin. When the locking tongue passes through the locking pin, the locking pin and the lock seat are in a relatively fixed state. When the locking tongue disengages from the locking pin, the locking pin and the lock seat are in a relatively movable state.

[0010] In the aforementioned grooving machine retraction mechanism, the baffle plate is provided with a clearance hole for the locking pin shaft to pass through, and the lock seat is provided with a through hole for the locking pin shaft to pass through. The clearance hole and the through hole are arranged opposite to each other.

[0011] In the aforementioned grooving machine retraction mechanism, the lock seat has a through hole for the locking tongue to move, and the lock pin has a positioning hole for the locking tongue to pass through. The through hole and the positioning hole are arranged opposite to each other.

[0012] In the above-mentioned grooving machine retraction mechanism, a first stop is provided on the fixed base, and a second stop is provided on the baffle plate. The first stop and the second stop are arranged opposite to each other, and the fixed base can slide so that the end of the first stop and the end of the second stop abut against each other.

[0013] In the above-mentioned grooving machine retraction mechanism, the driving component includes a rotary drive source, a lead screw, a nut, a slide rail, and a slider. The output end of the rotary drive source is connected to the lead screw. The nut is sleeved on the outside of the lead screw and the two are threaded together. The nut is connected to the puller seat. The slider is slidably disposed on the slide rail and connected to the puller seat.

[0014] In the above-mentioned grooving machine retraction mechanism, a second slider is slidably arranged on the slide rail, and the second slider is connected to the fixed base.

[0015] In summary, the beneficial effects of this utility model compared to the prior art are as follows: Before loading, the cutter holder and the fixed seat are in a relatively fixed state. The drive unit drives the cutter holder to slide, which in turn drives the blade, fixed seat, and cutter bar to slide away from the material loading station, thus avoiding interference with the material. This eliminates the need for reserved space for material loading and reduces space occupation. After loading, the drive unit drives the cutter holder to slide back to its original position, which in turn drives the blade, fixed seat, and cutter bar to slide back to their original position, allowing the blade and cutter bar to enter the material. Before processing the material, the cutter holder and the fixed seat are separated, ensuring that the drive unit's sliding of the cutter holder only moves the blade to process the material.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A tool retraction mechanism for a grooving machine, such as Figures 1 to 9 As shown, it includes a base 1, a blade 2, and a blade 3. The blade 2 is used to support the blade 3.

[0020] A puller holder 4 is slidably mounted on the base 1. The puller holder 4 is connected to the blade 3. A drive component 5 is provided on the base 1 to drive the puller holder 4 to slide.

[0021] In this embodiment, the driving component 5 includes a rotary driving source 51, a lead screw 52, ​​a nut 53, a slide rail 54, and a slider 55. The rotary driving source 51 is preferably a motor. The output end of the rotary driving source 51 is connected to the lead screw 52. The nut 53 is sleeved on the outside of the lead screw 52 and the two are threaded together. The nut 53 is connected to the broach holder 4. The slider 55 is slidably disposed on the slide rail 54 and connected to the broach holder 4.

[0022] The rotary drive source 51 drives the lead screw 52 to rotate, causing the nut 53 to move along the length of the lead screw 52 and driving the broach seat 4 and the slider 55 to move along the slide rail 54.

[0023] A fixed seat 6 is slidably mounted on the base 1. The fixed seat 6 is connected to the tool bar 2. A slider 19 is slidably mounted on the slide rail 54. The slider 19 is connected to the fixed seat 6. The slider 19 and the slide rail 54 cooperate to guide the sliding of the fixed seat 6.

[0024] A baffle 11 is installed on the base 1, a stop block 17 is provided on the fixed seat 6, and a stop block 18 is provided on the baffle 11. The stop block 17 and the stop block 18 are arranged opposite to each other. The fixed seat 6 can slide so that the end of the stop block 17 abuts against the end of the stop block 18. The abutting action of the two ensures the relative position stability of the fixed seat 6 and the baffle 11, thereby ensuring the relative position stability of the fixed seat 6 and the base 1. It also avoids the baffle 11 and the fixed seat 6 from directly contacting each other, thus preventing wear and large vibrations.

[0025] The cutter holder 4 and the fixed seat 6 can be in a relatively fixed state or a separated state. Specifically, the fixed seat 6 is provided with a positioning pin 7 and the cutter holder 4 is provided with a positioning sleeve 8. When the positioning pin 7 is inserted into the positioning sleeve 8, the cutter holder 4 and the fixed seat 6 are in a fixed state. When the positioning pin 7 is disengaged from the positioning sleeve 8, the cutter holder 4 and the fixed seat 6 are in a separated state.

[0026] It should be noted that in this embodiment, the positioning sleeve 8 is the positioning sleeve 8 of the flexible positioner in the prior art, and the positioning pin 7 is the positioning pin 7 of the flexible positioner in the prior art. The specific structure of the positioning pin 7 and the positioning sleeve 8 and their working principle are prior art, and will not be described in detail here.

[0027] The fixed seat 6 and the base 1 can remain relatively fixed, so that when the driving component 5 drives the broach seat 4 to slide, the positioning pin 7 disengages from the positioning sleeve 8.

[0028] It should be noted that, specifically, to keep the fixed seat 6 and the base 1 relatively fixed, the baffle 11 is provided with a locking seat 10 and a locking element 9, and the fixed seat 6 is provided with a locking pin 12. The locking element 9 can keep the locking pin 12 and the locking seat 10 in a relatively fixed state or in a relatively movable state. That is, by using the locking element 9 to keep the locking pin 12 and the locking seat 10 in a relatively fixed state, the fixed seat 6 and the baffle 11 are relatively fixed, thereby achieving the relative fixation of the fixed seat 6 and the base 1.

[0029] The locking component 9 includes a driving component 91 and a locking tongue 92. In this embodiment, the driving component 91 is preferably a cylinder. Alternatively, the driving component 91 can also be an electric cylinder. The driving component 91 is mounted on the baffle 11. The locking tongue 92 is slidably disposed in the lock seat 10. The lock seat 10 has a through hole 15 for the locking tongue 92 to move. The output end of the driving component 91 is connected to the locking tongue 92. The driving component 91 is used to drive the locking tongue 92 to move, so that the locking tongue 92 passes through or disengages from the locking pin shaft 12. The locking pin shaft 12 has a positioning hole 16 for the locking tongue 92 to pass through. The through hole 15 and the positioning hole 16 are arranged opposite to each other.

[0030] The baffle 11 has a clearance hole 13 for the lock pin 12 to pass through, and the lock seat 10 has a through hole 14 for the lock pin 12 to pass through. The clearance hole 13 and the through hole 14 are arranged opposite to each other.

[0031] When the latch 92 passes through the locking pin 12, the locking pin 12 is restricted by the latch 92 and the through hole 14 and cannot move. At this time, the locking pin 12 and the lock seat 10 are in a relatively fixed state. When the latch 92 disengages from the locking pin 12, the locking pin 12 is no longer restricted by the latch 92 and can move along the through hole 14. At this time, the locking pin 12 and the lock seat 10 are in a relatively movable state.

[0032] When the cutter holder 4 and the fixed seat 6 are in a relatively fixed state, the driving component 5 drives the cutter holder 4 to slide. The cutter holder 4 drives the blade 3, the fixed seat 6 and the cutter bar 2 to slide. That is, before the material is loaded, the blade 3 and the cutter bar 2 are moved away from the material loading station to avoid interference with the material during loading. After the material is loaded, the driving component 5 drives the cutter holder 4 to slide back to its original position. The cutter holder 4 drives the blade 3, the fixed seat 6 and the cutter bar 2 to slide back to their original position, so that the blade 3 and the cutter bar 2 enter the material.

[0033] When the cutter holder 4 is separated from the fixed seat 6, the driving component 5 drives the cutter holder 4 to slide, and the cutter holder 4 drives the blade 3 to slide. That is, at this time, the driving component 5 drives the cutter holder 4 to slide, which only drives the blade 3 to move and process the material.

[0034] In the prior art, materials are usually inserted from the end of the cutter bar 2 along its axial direction, so space needs to be reserved to avoid the material during feeding. In this embodiment, the drive component 5 drives the puller seat 4 to slide, and the puller seat 4 drives the blade 3, the fixed seat 6 and the cutter bar 2 to slide, so that the blade 3 and the cutter bar 2 are away from the material feeding position, eliminating the need for the space reserved for material feeding and effectively reducing space occupation.

[0035] The working principle of this utility model is as follows: Before feeding, the drive unit 5 drives the broaching cutter holder 4 to slide close to the fixed seat 6 until the positioning pin 7 is inserted into the positioning sleeve 8, making the broaching cutter holder 4 and the fixed seat 6 relatively fixed. Then, the drive unit 5 drives the broaching cutter holder 4 to slide, which in turn drives the blade 3, the fixed seat 6, and the cutter bar 2 to slide away from the material feeding position, thus avoiding interference during material feeding. After feeding is completed, the drive unit 5 drives the broaching cutter holder 4 to slide back to its original position, which in turn drives the blade 3, the fixed seat 6, and the cutter bar 2 to slide back to their original position until the stop block is reached. The end of 17 abuts against the end of the second stop 18. At this time, both the blade 3 and the shank 2 enter the material. Then, the drive component 91 drives the locking tongue 92 to move along the through hole 15 until it passes through the locking pin 12 through the positioning hole 16, so that the locking pin 12 and the locking seat 10 are in a relatively fixed state, thereby keeping the fixed seat 6 and the base 1 relatively fixed. At this time, the drive component 5 drives the pull knife seat 4 to slide away from the fixed seat 6, and the positioning pin 7 disengages from the positioning sleeve 8, so that the pull knife seat 4 and the fixed seat 6 are in a separated state. After that, the drive component 5 drives the pull knife seat 4 to move only the blade 3 to process the material.
