Description

Technical Field

[0001] The utility model relates to the technical field of machine tool fixtures, in particular to a machine tool fixture device with inspection accuracy. Background Art

[0002] A machine tool refers to a machine used to manufacture machines and machinery. During the process of machine tools processing workpiece products, a fixture is needed to limit and clamp the workpiece. A fixture refers to a device used to fix the processing object during the mechanical manufacturing process so that it occupies the correct position for construction or testing.

[0003] When machining a workpiece on a machine tool, in order for the workpiece surface to meet the technical requirements of size, geometry, and relative position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before machining.

[0004] At present, in the prior art, there are machine tool fixture devices with inspection accuracy in use. When the user installs the fixture, the bottom of the fixture is very likely to have a different horizontal position when placed. The different levels can easily cause large subsequent processing errors of the workpiece, making it inconvenient for the user to perform a simple horizontal position inspection of the fixture in a timely manner. Therefore, a machine tool fixture device with inspection accuracy is proposed to solve the above problem. Utility Model Content

[0005] The utility model provides a machine tool fixture device with inspection accuracy to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A machine tool fixture device with inspection accuracy comprises a base and a bottom plate, wherein an inspection mechanism is installed outside the base, a positioning mechanism is installed above the bottom plate, and a placement plate is fixedly connected to the upper surface of the bottom plate and inside the positioning mechanism;

[0008] The inspection mechanism includes an inspection plate fixedly connected to the side wall of the base, a placement groove is opened inside the inspection plate, a plurality of balls are placed inside the placement groove, both side ports of the placement groove are slidably connected with inspection pins, the outer wall of the inspection plate is fixedly connected with a bayonet, and the number of the bayonet pins is two, both sides of the inspection plate are fixedly connected with a ruler, and the outer walls of the two inspection pins are fixedly connected with pointers.

[0009] By adopting the above technical solution, the cross-section of the placement groove is a "U"-shaped structure, and the cross-sections of the two inspection pins are both "I"-shaped structures.

[0010] Due to the adoption of the above technical solution, the placement groove of the "U"-shaped structure facilitates the sliding movement of the ball inside, thereby also facilitating the inspection pin to float up and down.

[0011] By adopting the above technical solution, the cross-sections of the two bayonet pins are both "T"-shaped structures, and the front ends of the two bayonet pins are in contact with the outer walls of the two inspection pins.

[0012] Due to the adoption of the above technical solution, the locking pin can well limit and position the two inspection pins, thereby preventing the inspection pins from falling off during operation.

[0013] Using the above technical solution, the positioning mechanism includes a horizontal plate fixedly connected to the upper surface of the base plate, both ends of the horizontal plate are rotatably connected to side plates, the insides of the two side plates are rotatably connected to receiving plates, the upper surfaces of the receiving plates are rotatably connected to positioning wheels, the outer end of one of the side plates is rotatably connected to a screw, the outer wall of the screw is threadedly connected to a nut, and the outer end of the other side plate is provided with a stabilizing groove.

[0014] Due to the adoption of the above technical solution, the two side panels are positioned by the rotation of a screw rod. Therefore, such a design can not only make the force more uniform and stable, but also facilitate the operation of the user.

[0015] By adopting the above technical solution, the horizontal cross-section of the placement plate is an "I"-shaped structure, the horizontal cross-sections of the two receiving plates are both "V"-shaped structures, and the stabilizing groove and the screw rod are adapted to each other.

[0016] Due to the adoption of the above technical solution, the receiving plate with a "V"-shaped structure can not only limit the circular products, but also position the directional products.

[0017] By adopting the above technical solution, a stabilizing mechanism is installed inside the base, and the stabilizing mechanism includes a mounting groove opened inside the base, the inner bottom of the mounting groove is rotatably connected to a knob, the inner side wall of the mounting groove is fixedly connected to a limiting plate, the top of the knob is fixedly connected to a stud, the outer wall of the stud is threadedly connected to a sliding sleeve, and the top of the sliding sleeve is fixedly connected to a positioning plate.

[0018] Due to the adoption of the above technical solution, a positioning plate with lifting motion is used to receive and process the bottom plate after adjustment, which can ensure that the bottom plate can be well leveled and stable.

[0019] By adopting the above technical solution, the front end of the limit plate and the outer wall of the sliding sleeve are slidably connected, and the positioning plate forms a lifting structure through the cooperation between the sliding sleeve and the stud and the knob.

[0020] Due to the adoption of the above technical solution, the limit plate can well limit and stabilize the sliding sleeve in the lifting state, and can ensure that the sliding sleeve is only in the lifting state, not the rotating state.

[0021] By adopting the above technical scheme, the outer wall of the horizontal plate is fixedly connected to the mounting plate, and a clamping mechanism is installed above the mounting plate. The clamping mechanism includes a clamping plate fixedly connected to the upper surface of the mounting plate, the top of the clamping plate is fixedly connected to a connecting plate, the internal thread of the connecting plate is connected to a connecting bolt, the front end of the connecting bolt is rotatably connected to a slider, the top of the clamping plate and one side of the slider is rotatably connected to a locking plate, and the inside of the locking plate is rotatably connected to a guide wheel.

[0022] Due to the adoption of the above technical solution, the flipping movement of the locking plate can limit and stabilize thin products such as sheet metal parts, thereby making the device more compatible during positioning.

[0023] By adopting the above technical solution, the cross section of the slider is a right-angled trapezoidal structure, the guide wheel is made of rubber material, and the cross section of the locking plate is an "L"-shaped structure.

[0024] Due to the adoption of the above technical solution, the slider with the inclined surface structure can quickly control the locking plate to perform a flipping movement, which can make the force more even and is convenient for users to operate.

[0025] Compared with the prior art, the utility model has achieved the following technical advances:

[0026] 1. The utility model provides a machine tool fixture device with inspection accuracy. Due to gravity, the bottom plate will resist the control inspection pin. If unevenness occurs, the ball will move inside the placement groove. Since the placement groove is U-shaped, the inspection pin will move up and down on both sides. The user needs to observe the position of the pointer on the ruler. When the pointer remains consistent in the position of the ruler, the bottom plate is in a horizontal state. This design is convenient for users to perform horizontal inspection before clamping the product.

[0027] 2. The utility model provides a machine tool fixture device with inspection accuracy. Sheet metal products are placed on the upper surface of the placement plate, and then the user rotates the connecting bolt to control the slider to move forward. When the slider moves forward, it can drive the beveled oblique control guide wheel to control the flipping movement of the locking plate. At this time, the locking plate flipped downward can limit the sheet metal. This design can not only position three-dimensional workpieces, but also position sheet metal products.

[0028] 3. The utility model provides a machine tool fixture device with inspection accuracy. The knob can drive the stud to rotate. The rotation of the stud can control the sleeve to move up and down. At this time, the rising sleeve can drive the positioning plate to support the bottom of the base plate, which is convenient for timely positioning of the base plate after adjustment, thereby preventing secondary offset.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the embodiments:

[0039] The inspection mechanism 2 includes an inspection plate 201 fixedly connected to the side wall of the base 1, a placement groove 202 is opened inside the inspection plate 201, a plurality of balls 203 are placed inside the placement groove 202, both side ports of the placement groove 202 are slidably connected with inspection pins 205, the outer wall of the inspection plate 201 is fixedly connected with a bayonet 207, and the number of the bayonet 207 is two, both sides of the inspection plate 201 are fixedly connected with a ruler 204, and the outer walls of the two inspection pins 205 are fixedly connected with pointers 206.

[0040] The cross section of the placement groove 202 is a "U"-shaped structure, and the cross sections of the two inspection pins 205 are both "I"-shaped structures. The "U"-shaped placement groove 202 facilitates the ball 203 to slide inside, thereby also facilitating the inspection pin 205 to float up and down.

[0041] The cross-sections of the two bayonet pins 207 are both "T"-shaped. The front ends of the two bayonet pins 207 are in contact with the outer walls of the two inspection pins 205. The bayonet pins 207 can well limit and position the two inspection pins 205, thereby preventing the inspection pins 205 from falling off during operation.

[0042] In this embodiment, when the base plate 4 is placed on the inspection pin 205, due to gravity, the base plate 4 will resist the control inspection pin 205. If unevenness occurs, the sphere 203 will move inside the placement groove 202. Since the placement groove 202 is U-shaped, the inspection pin 205 will move up and down on both sides. The user needs to observe the position of the pointer 206 on the ruler 204. When the pointer 206 remains consistent in the position of the ruler 204, the base plate 4 is in a horizontal state.

[0043] Example 2

[0044] like Figure 4-5 As shown, on the basis of Example 1, the utility model provides a technical solution: the positioning mechanism 5 includes a horizontal plate 501 fixedly connected to the upper surface of the bottom plate 4, both ends of the horizontal plate 501 are rotatably connected to the side plates 502, the insides of the two side plates 502 are rotatably connected to the receiving plates 503, the upper surfaces of the receiving plates 503 are rotatably connected to the positioning wheels 504, the outer end of one of the side plates 502 is rotatably connected to a screw rod 505, the outer wall of the screw rod 505 is threadedly connected to a nut 506, and the outer end of the other side plate 502 is provided with a stabilizing groove 507, and the two side plates 502 are force-positioned by rotating a screw rod 505. Therefore, such a design can not only make the force more uniform and stable, but also facilitate the user to operate.

[0045] The horizontal cross-section of the placement plate 6 is an "I"-shaped structure, and the horizontal cross-sections of the two receiving plates 503 are both "V"-shaped structures. The stabilizing groove 507 and the screw rod 505 are adapted to each other. The "V"-shaped receiving plate 503 can not only limit the circular products, but also position the directional products.

[0047] The front end of the limit plate 306 and the outer wall of the sleeve 304 are slidably connected. The positioning plate 305 forms a lifting structure through the cooperation between the sleeve 304 and the stud 303 and the knob 302. The limit plate 306 can effectively limit and stabilize the sleeve 304 in the lifting state, and can ensure that the sleeve 304 is only in the lifting state, not the rotating state.

[0048] In this embodiment, the knob 302 is rotated, and the knob 302 can drive the stud 303 to rotate. The rotation of the stud 303 can control the sleeve 304 to move up and down. At this time, the rising sleeve 304 can drive the positioning plate 305 to support the bottom of the base plate 4, and place the product to be clamped in the grooves on both sides of the placement plate 6. Then, the side plates 502 are flipped over in turn, and then the screw 505 is flipped and buckled into the stabilizing groove 507. The nut 506 is rotated to make the two side plates 502 move toward the placement plate 6 under force. When under force, the positioning wheel 504 can stably clamp the workpiece on the placement plate 6.

[0051] The cross section of the slider 804 is a right-angled trapezoidal structure, the guide wheel 806 is made of rubber material, the cross section of the locking plate 805 is an "L"-shaped structure, and the inclined slider 804 can quickly control the locking plate 805 to flip, which can make the force more even and is also convenient for users to operate.

[0052] In this embodiment, the placement plate 6 is mainly used for limiting the installation of three-dimensional products, and the user can also place sheet metal products on the upper surface of the placement plate 6, and then the user rotates the connecting bolt 803 to control the slider 804 to move forward. When the slider 804 moves forward, it can drive the beveled control guide wheel 806 to control the locking plate 805 to flip over. At this time, the locking plate 805 flipped downward can limit the sheet metal.

[0053] The following is a detailed description of the working principle of the atmospheric suspended matter detection system based on machine vision.

[0054] like Figure 1-6As shown, first place the bottom plate 4 on the inspection pin 205. Due to gravity, the bottom plate 4 will resist the control inspection pin 205. If unevenness occurs, the ball 203 will move inside the placement groove 202. Since the placement groove 202 is U-shaped, the inspection pin 205 will move up and down on both sides. The user needs to observe the position of the pointer 206 on the ruler 204. When the pointer 206 is in the same position as the ruler 204, the bottom plate 4 is in a horizontal state. Rotate the knob 302, the knob 302 can drive the stud 303 to rotate, and the rotation of the stud 303 can control the sliding sleeve 304 to move up and down. At this time, the rising sliding sleeve 304 can drive the positioning plate 305 to the bottom The bottom of the plate 4 is supported, and the product to be clamped is placed in the grooves on both sides of the placement plate 6.

The user can also place sheet metal products on the upper surface of the placement plate 6, and then the user rotates the connecting bolt 803 to control the slider 804 to move forward. When the slider 804 moves forward, it can drive the beveled side to control the guide wheel 806 to control the flipping movement of the locking plate 805. At this time, the flipped downward locking plate 805 can limit the sheet metal.
