Description

Technical Field

[0001] The utility model belongs to the technical field related to tooling, and particularly relates to a turntable structure for tooling. Background Technique

[0002] In the process of headlamp production, the lamp cover and the housing of the rear lamp usually adopt a welding process. In order to improve the production rhythm, the original single-station is changed to a double-station turntable; and in order to reduce the tooling changeover time, a tooling quick-change device is provided on the turntable.

[0003] However, for a heavy-duty turntable, the tooling fixed above it is generally relatively heavy. For existing patents, the problems such as quick replacement of tooling and turntable positioning during the use of the turntable are not considered. Summary of the Utility Model

[0004] In order to solve the technical problem of inability to achieve quick positioning on the tooling turntable in the background technique, the purpose of the utility model is to provide a turntable structure for tooling, which can solve the above problems.

[0005] The technical solution to achieve the purpose of the utility model is: a turntable structure for tooling, including a fixed base, a fixed plate and a turntable. The fixed plate is installed on the fixed base, and the turntable is rotatably installed above the fixed plate. The tooling is fixed on the turntable; a turntable positioning component is installed on the fixed plate. The turntable positioning component includes a positioning pin, and a positioning hole corresponding to the positioning pin is arranged on the turntable. The positioning pin is inserted into the positioning hole, and the turntable is positioned and limited in rotation through the cooperation of the positioning pin and the positioning hole.

[0006] In this solution, a turntable positioning component is arranged on the fixed plate to position and limit the rotation of the turntable. The specific structure includes arranging a positioning pin on the fixed plate. When the turntable rotates to a specified position, the position of the positioning hole on the turntable corresponds to the position of the positioning pin. At this time, the positioning pin is inserted into the positioning hole to complete the positioning and limiting rotation of the turntable. At the same time, the tooling is installed and fixed on the turntable. Therefore, the positioning of the turntable is the positioning of the tooling. Even if the tooling on the turntable is heavy, as long as the positioning of the turntable is completed, the quick positioning of the tooling is completed, and its continuous rotation is also limited. The structure of this device is simple, which plays a role in quickly positioning the turntable and the tooling, and is more convenient, fast, time-saving and labor-saving when replacing or installing the tooling.

[0007] The turntable positioning assembly further includes a turntable positioning cylinder, a cylinder mounting seat, and a proximity switch. The cylinder mounting seat is mounted on the fixed plate. The turntable positioning cylinder and the proximity switch are installed on the cylinder mounting seat. The output end of the turntable positioning cylinder is connected with a positioning pin. The proximity switch is used to sense the rotation position of the turntable and control the start of the turntable positioning cylinder. The automatic control of the rising of the positioning pin can be realized by using the turntable positioning cylinder. The proximity switch can be a position sensor. When it detects that the turntable rotates to a specified position, it will send a signal, and the turntable positioning cylinder can drive the positioning pin to accurately insert into the positioning hole on the turntable.

[0008] A driving device is installed on the fixed base. The driving device is connected to the turntable and used to drive the rotation of the turntable. The driving device includes a servo motor, a gear, and a toothed slewing bearing. The servo motor is fixed on the fixed base. The gear is installed at the output end of the servo motor. The gear and the toothed slewing bearing are installed in cooperation. The toothed slewing bearing passes through the fixed plate and is fixedly connected to the turntable. Since the tooling on the turntable may be heavy, using the servo motor for driving is more flexible, which solves the problems of time-consuming, laborious, and low efficiency in manual driving.

[0009] A tooling clamping assembly is arranged on the turntable and used to fix the tooling on the turntable. The clamping assembly includes a clamping cylinder, a clamping cylinder mounting seat, and a clamping head. The clamping cylinder mounting seat is fixed on the turntable. The clamping cylinder is installed on the clamping cylinder mounting seat. The clamping head is installed at the end of the piston rod of the clamping cylinder and used to clamp the tooling. When the turntable rotates, there is a centrifugal force. If the tooling is not fixed on the turntable, it may be thrown off the turntable. Therefore, a fixing device is needed. This fixing device also adopts a cylinder structure. The clamping cylinder is used to automatically fix the tooling. Specifically, the clamping head is used to press and clamp the tooling for fixing.

[0010] The clamping head is a wedge block. The wedge block is installed at the end of the piston rod of the clamping cylinder through a floating joint. The tooling has a clamping block that cooperates with the wedge block. The wedge block presses on the clamping block. That is, the clamping head is in the shape of a wedge block and has a pressing inclined surface, while the clamping block on the tooling has a pressed inclined surface corresponding to the pressing inclined surface. After the two are matched and installed, the clamping head plays a role in pressing the clamping block, achieving the effect of fixing the tooling.

[0011] There are multiple clamping assemblies, which are arranged corresponding to each other. For example, two opposite clamping assemblies are respectively located at both ends of the tooling, which can play a role in clamping the tooling and further fixing the tooling on the turntable.

[0012] The turntable is also provided with guide wheels, limit blocks and a tooling positioning assembly. There are multiple guide wheels, which are located on both sides of the turntable; the limit blocks are located at the middle position of the turntable; the tooling positioning assembly is located at the edge of one side of the turntable far from the guide wheels. The guide wheels are rotatable, which facilitates the movement of the tooling when installing the tooling on the turntable, saving the laborious problem during handling. When the tooling slides to the designated position on the turntable, it will be limited by the limit block. Then, the tooling positioning assembly 11 will further limit the tooling to prevent it from continuing to slide and affecting the accurate positioning and fixing.

[0013] The tooling positioning assembly includes a positioning cylinder mounting seat, a positioning cylinder, a guide bushing and a tooling positioning pin. The positioning cylinder mounting seat is fixed on the turntable, the positioning cylinder is installed on the positioning cylinder mounting seat, the guide bushing is also installed on the positioning cylinder mounting seat, the tooling positioning pin is installed on the piston rod of the positioning cylinder, and the tooling positioning pin is telescopically arranged in the guide bushing. A positioning small hole matching the tooling positioning pin is provided on the tooling, and the tooling positioning pin is inserted into the positioning small hole. When the tooling slides to the designated position on the turntable by relying on the guide wheels, the positioning cylinder is activated, driving the tooling positioning pin to move upward until it is inserted into the positioning pin hole on the tooling, completing the positioning and limiting of the tooling on the turntable.

[0014] The turntable structure also includes a pneumatic and electrical plug-in assembly. The pneumatic and electrical plug-in assembly includes an assembly cylinder mounting plate, a slide cylinder, a pneumatic and electrical plug-in female head and a buffer. A pneumatic and electrical plug-in male head corresponding to the pneumatic and electrical plug-in female head is provided on the tooling; the slide cylinder is installed on the assembly cylinder mounting plate, the assembly cylinder mounting plate is installed on the edge of one side of the turntable, the pneumatic and electrical plug-in female head is installed on the slide cylinder, and a buffer is provided on the side of the slide cylinder, which is used for the accurate insertion of the pneumatic and electrical plug-in female head and the pneumatic and electrical plug-in male head. In order to further improve the installation efficiency of the tooling, the pneumatic and electrical circuits required on the tooling are connected by plugging the pneumatic and electrical plug-in female head and the pneumatic and electrical plug-in male head, with higher installation efficiency. Specifically, it is driven by the slide cylinder to drive the pneumatic and electrical plug-in female head to move upward until it is matched and plugged with the pneumatic and electrical plug-in male head.

[0015] The turntable structure further includes a tooling lifting assembly. The tooling lifting assembly includes a cylinder mounting plate, a lifting cylinder, a guide shaft, a linear bearing, a floating connector, a tooling lifting plate, and a steel ball roller. The cylinder mounting plate is mounted on the fixed plate. The floating joint is mounted on the tooling lifting plate and is located between the cylinder mounting plate and the tooling lifting plate. A linear bearing and a guide shaft are also mounted between the cylinder mounting plate and the tooling lifting plate. A steel ball roller is further mounted on the side of the tooling lifting plate facing the turntable. The turntable has a perforation corresponding to the steel ball roller. After the steel ball roller passes through the perforation, it abuts against the tooling and lifts the tooling off the turntable. Since the tooling on the turntable may be a double-station tooling, which is large and heavy, it is rather laborious to carry it manually. Therefore, this device is provided with a tooling lifting assembly, that is, when the lifting cylinder is activated, under the guiding action of the guide shaft and the support bearing, the steel ball roller is pushed out from the perforation on the turntable under the action of the lifting cylinder and lifts the tooling off the turntable. Since the ejecting device is a steel ball roller and can roll, the tooling can slide and be transported on the steel ball roller after being lifted off the turntable, which further saves time and effort. There can be multiple steel ball rollers in one tooling lifting assembly, and there can be multiple tooling lifting assemblies in one turntable structure, depending on the requirements. The steel ball roller has a rectangular mounting portion and can pass through the perforation.

[0016] This structure further includes an automated control system, such as a PLC control system, etc., to achieve automated control of the turntable positioning assembly, the driving device, the tooling clamping assembly, the tooling positioning assembly, the gas-electricity plugging assembly, and the tooling lifting assembly.

[0017] Adopting the above technical solutions, the utility model has the following beneficial effects:

[0018] (1) In the solution, a positioning pin is provided on the fixed plate under the turntable, and a positioning hole corresponding to the positioning pin is provided on the turntable. When the turntable rotates to a specified position, the positioning pin is inserted into the positioning hole to complete the positioning and limit the rotation of the turntable. Since the tooling is mounted on the turntable, the positioning of the tooling is also completed.

[0019] (2) Further adding a turntable positioning cylinder and a proximity switch makes it more accurate to determine the rotation position of the turntable and the automatic insertion of the positioning pin into the positioning hole.

[0020] (3) Since the turntable may be installed with a fixed double-station tooling, which is large in volume and heavy in weight, a driving device for automatically rotating the turntable is added, which is more time-saving and labor-saving compared with manual operation.

[0021] (4) A tooling clamping assembly is provided on the turntable to facilitate fixing the tooling on the turntable.

[0022] (5) The provided guide wheels and limit blocks facilitate the positioning of the tooling during movement on the turntable. The tooling positioning component further accurately positions the tooling and addresses the issue of misalignment during movement and placement.

[0023] (6) The pneumatic and electrical plug - in component solves the problem of time - consuming and laborious connection of the circuits required on the tooling. By directly inserting the pneumatic and electrical female plug and the pneumatic and electrical male plug, the connection is quick and convenient.

[0024] (7) The tooling lifting component provided on the fixed plate can automatically lift the tooling off the turntable when the tooling is large and heavy. Description of the Drawings

Detailed Embodiments

[0033] Embodiment:

[0034] As Figure 1 - Figure 2 shown, this embodiment provides a turntable 3 structure for a tooling, including a fixed base 1, a fixed plate 2, and a turntable 3. The fixed plate 2 is installed on the fixed base 1, and the turntable 3 is rotatably installed above the fixed plate 2. The tooling is fixed on the turntable 3. A turntable positioning assembly 12 is installed on the fixed plate 2. The turntable positioning assembly 12 includes a positioning pin 4.3. A positioning hole corresponding to the positioning pin 4.3 is provided on the turntable 3. The positioning pin 4.3 is inserted into the positioning hole, and the turntable 3 is positioned and its rotation is limited through the cooperation of the positioning pin 4.3 and the positioning hole. In this solution, the turntable positioning assembly 12 is provided on the fixed plate 2 to position and limit the rotation of the turntable 3. The specific structure includes providing a positioning pin 4.3 on the fixed plate 2. When the turntable 3 rotates to a specified position, the position of the positioning hole on the turntable 3 corresponds to the position of the positioning pin 4.3. At this time, the positioning pin 4.3 is inserted into the positioning hole to complete the positioning and limiting of the rotation of the turntable 3. At the same time, the tooling is installed and fixed on the turntable 3. Therefore, the positioning of the turntable 3 is the positioning of the tooling. Even if the tooling on the turntable 3 is heavy, as long as the positioning of the turntable 3 is completed, the quick positioning of the tooling is completed, and its continuous rotation is also limited. The structure of this device is simple, which plays a role in quickly positioning the turntable 3 and the tooling, and is more convenient, fast, time-saving and labor-saving when replacing or installing the tooling.

[0035] The turntable positioning assembly 12 further includes a turntable positioning cylinder 4.1, a cylinder mounting seat 4.2, and a proximity switch 4.4. The cylinder mounting seat 4.2 is installed on the fixed plate 2. The turntable positioning cylinder 4.1 and the proximity switch 4.4 are installed on the cylinder mounting seat 4.2. The output end of the turntable positioning cylinder 4.1 is connected to the positioning pin 4.3. The proximity switch 4.4 is used to sense the rotation position of the turntable 3 and control the start of the turntable positioning cylinder 4.1. The automatic control of the rising of the positioning pin 4.3 can be realized by using the turntable positioning cylinder 4.1. The proximity switch 4.4 can be a position sensor. When it detects that the turntable 3 rotates to a specified position, it will send a signal, and the turntable positioning cylinder 4.1 can drive the positioning pin 4.3 to accurately insert into the positioning hole on the turntable 3.

[0036] A driving device is installed on the fixed base 1. The driving device is connected to the turntable 3 and is used to drive the rotation of the turntable 3. The driving device includes a servo motor 4, a gear 5, and a toothed slewing bearing. The servo motor 4 is fixed on the fixed base 1. The output end of the servo motor 4 is equipped with the gear 5. The gear 5 is installed in cooperation with the toothed slewing bearing 6. The toothed slewing bearing 6 passes through the fixed plate 2 and is fixedly connected to the turntable 3. Since the tooling on the turntable 3 may be heavy, driving by the servo motor 4 is more flexible, solving the problems of time-consuming, laborious, and low efficiency during manual driving.

[0037] As Figure 3 shown, a tooling clamping assembly 9 is provided on the turntable 3 and is used to fix the tooling on the turntable 3. The clamping assembly 9 includes a clamping cylinder 1.1, a clamping cylinder mounting seat 1.2, and a clamping head. The clamping cylinder mounting seat 1.2 is fixed on the turntable 3. The clamping cylinder 1.1 is installed on the clamping cylinder mounting seat 1.2. The clamping head is installed at the end of the piston rod of the clamping cylinder 1.1 and is used to clamp the tooling. When the turntable 3 rotates, there is a centrifugal force. If the tooling is not fixed on the turntable 3, it may be thrown off the turntable 3. Therefore, a fixing device is needed. This fixing device also adopts a cylinder structure, and the clamping cylinder 1.1 automatically fixes the tooling. Specifically, the tooling is fixed by pressing and clamping the tooling with the clamping head.

[0038] The clamping head is a wedge block 1.4. The wedge block 1.4 is installed at the end of the piston rod of the clamping cylinder 1.1 through a floating joint 1.3. The tooling has a clamping block that cooperates with the wedge block 1.4. The wedge block 1.4 is pressed against the clamping block. That is, the clamping head is in the shape of a wedge block 1.4 and has a pressing inclined surface. The clamping block on the tooling has a pressed inclined surface corresponding to the pressing inclined surface. After the two are matched and installed, the clamping head plays a role in pressing the clamping block, achieving the effect of fixing the tooling.

[0039] There are multiple clamping assemblies 9, and they are arranged corresponding to each other. For example, two relatively clamping assemblies 9 are respectively located at both ends of the tooling, which can clamp the tooling and further fix the tooling on the turntable 3.

[0040] As Figure 4As shown in the figure, a guide wheel 7, a limit block 8 and a tooling positioning component 11 are further arranged on the turntable 3. There are multiple guide wheels 7, which are located on both sides of the turntable 3; the limit block 8 is located at the middle position of the turntable 3; the tooling positioning component 11 is located at one side edge of the turntable 3 far from the guide wheel 7. The guide wheel 7 is rotatable, which facilitates the movement of the tooling when installing the tooling on the turntable 3, saving the laborious problem during handling. When the tooling slides to the designated position on the turntable 3, it will be limited by the limit block 8, and then the tooling positioning component 11 will further limit the tooling to prevent it from continuing to slide and affecting the accurate positioning and fixing. The tooling positioning component 11 includes a positioning cylinder mounting seat 3.1, a positioning cylinder 3.2, a guide bushing 3.3 and a tooling positioning pin 3.4. The positioning cylinder mounting seat 3.1 is fixed on the turntable 3, the positioning cylinder 3.2 is installed on the positioning cylinder mounting seat 3.1, the guide bushing 3.3 is also installed on the positioning cylinder mounting seat 3.1, the tooling positioning pin 3.4 is installed on the piston rod of the positioning cylinder 3.2, and the tooling positioning pin 3.4 telescopically moves within the guide bushing 3.3. A positioning small hole matching the tooling positioning pin 3.4 is arranged on the tooling, and the tooling positioning pin 3.4 is inserted into the positioning small hole. When the tooling slides to the designated position on the turntable 3 by relying on the guide wheel 7, the positioning cylinder 3.2 is started, driving the tooling positioning pin 3.4 to move upward until it is inserted into the positioning pin 4.3 hole on the tooling, completing the positioning and limiting of the tooling on the turntable 3.

[0041] As Figure 5 shown in the figure, the structure of the turntable 3 further includes an air-electricity pluggable component 10. The air-electricity pluggable component 10 includes a component cylinder mounting plate 2.1, a slide cylinder 2.2, an air-electricity pluggable female head 2.3 and a buffer 2.4. An air-electricity pluggable male head corresponding to the air-electricity pluggable female head 2.3 is arranged on the tooling; the slide cylinder 2.2 is installed on the component cylinder mounting plate 2.1, the component cylinder mounting plate 2.1 is installed on one side edge of the turntable 3, the air-electricity pluggable female head 2.3 is installed on the slide cylinder 2.2, and a buffer 2.4 is arranged on the side of the slide cylinder 2.2. The buffer 2.4 is used for the accurate insertion of the air-electricity pluggable female head 2.3 and the air-electricity pluggable male head. In order to further improve the installation efficiency of the tooling, the air-electricity lines required on the tooling are connected by plugging through the air-electricity pluggable female head 2.3 and the air-electricity pluggable male head, and the installation efficiency is higher. Specifically, it is driven by the slide cylinder 2.2 to drive the air-electricity pluggable female head 2.3 to move upward until it is matched and plugged with the air-electricity pluggable male head.

[0042] As Figure 6As shown, the structure of the turntable 3 further includes a tooling lifting assembly 13. The tooling lifting assembly 13 includes an assembly cylinder mounting plate 2.1, a lifting cylinder 5.2, a guide shaft 5.3, a linear bearing 5.4, a floating connector 5.5, a tooling lifting plate 5.6, and a ball roller 5.7. The assembly cylinder mounting plate 2.1 is mounted on the fixed plate 2. The floating joint 1.3 is mounted on the tooling lifting plate 5.6 and is located between the assembly cylinder mounting plate 2.1 and the tooling lifting plate 5.6. A linear bearing 5.4 and a guide shaft 5.3 are also mounted between the assembly cylinder mounting plate 2.1 and the tooling lifting plate 5.6. A ball roller 5.7 is further mounted on the side of the tooling lifting plate 5.6 facing the turntable 3. The turntable 3 has a perforation corresponding to the ball roller 5.7. After the ball roller 5.7 passes through the perforation, it abuts against the tooling and lifts the tooling off the turntable 3. Since the tooling on the turntable 3 may be a double-station tooling, which is large and heavy, it is rather laborious to carry it manually. Therefore, this device is provided with a tooling lifting assembly 13, that is, when the lifting cylinder 5.2 is started, under the guiding action of the guide shaft 5.3 and the support bearing, the ball roller 5.7 is pushed out from the perforation on the turntable 3 under the action of the lifting cylinder 5.2, and the tooling is lifted off the turntable 3. Since the ejecting device is the ball roller 5.7 and it can roll, the tooling can slide and be transported on the ball roller 5.7 after being lifted off the turntable 3, which further saves time and effort. There can be multiple ball rollers 5.7 in one tooling lifting assembly 13, and there can be multiple tooling lifting assemblies 13 in one turntable 3 structure, depending on the requirements. The ball roller 5.7 has a rectangular mounting portion and can pass through the perforation.

[0043] This structure further includes an automated control system, such as a PLC control system, etc., to achieve automated control of the turntable positioning assembly 12, the driving device, the tooling clamping assembly 9, the tooling positioning assembly 11, the gas-electricity plug-in assembly 10, and the tooling lifting assembly 13.

[0044] Working principle: When using this device, first place the tooling on the turntable 3, slide it to the designated position by using the guide wheel 7, and limit it with the limit block 8 and the tooling positioning assembly 11, and then fix it with the tooling clamping assembly 9. When the tooling needs to be rotated, use the driving device to drive the turntable 3 to rotate, and use the turntable positioning assembly 12 to quickly achieve positioning and limit rotation. When the tooling needs to be moved away, rely on the tooling lifting assembly 13 to lift the tooling off the turntable 3.

After the steel ball roller (5.7) passes through the through hole, it abuts against the tooling to lift the tooling away from the turntable (3).
