Description

Technical Field

[0001] This utility model relates to the field of servo turntable technology, and in particular to a quick-release load mounting flange for servo turntables. Background Technology

[0002] Servo turntables, as high-precision rotary positioning and motion control devices, are widely used in various industrial and scientific research applications such as automated testing, precision machining, radar antennas, and optical tracking. In these applications, servo turntables need to frequently mount or change different loads, such as test instruments, tooling fixtures, and sensors.

[0003] To ensure the rigidity and precision of the connection between the load and the servo turntable, flanges are used for installation. The load is fixed to a load flange, which is then fixed to the output flange of the servo turntable. This connection method must ensure high-strength locking to resist the inertial forces and vibrations generated during the high-speed start-stop and rotation of the turntable.

[0004] In the existing technology, the most common way to achieve this flange fixing is to use multiple bolts for circumferential tightening. The operator needs to use a wrench to align each bolt hole and tighten and loosen each bolt in turn.

[0005] This method of fastening with multiple bolts has obvious shortcomings. When the load on the servo turntable needs to be changed frequently, the process of repeatedly loosening and tightening multiple bolts is not only cumbersome and time-consuming, but also greatly reduces work efficiency. In situations where the installation space is limited, it is also very difficult to operate with tools, which seriously affects the flexibility and rapid response capability of the servo turntable equipment.

[0006] Therefore, this utility model proposes a quick-release load mounting flange for servo turntables to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of existing quick-release load mounting flanges for servo turntables, such as the need for multiple bolts for fastening, the need for tools to operate one by one when installing and removing the load, the cumbersome process, the time and effort required, and the low efficiency of disassembly and assembly, this utility model aims to provide a servo turntable quick-release load mounting flange with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a quick-release load mounting flange for a servo turntable, comprising:

[0009] The turntable connecting seat has a ball bearing fixedly connected to its inner wall, and a base positioning groove and a base locking hole are opened on the outer wall of the turntable connecting seat.

[0010] The quick-release flange body is detachably installed on the turntable connecting seat. The inner wall of the quick-release flange body is fixedly connected with a positioning protrusion, which engages with the positioning groove of the base. The top of the quick-release flange body is provided with a main body connecting end face, and the outer wall of the quick-release flange body is provided with a locking mounting groove, which corresponds to the position of the locking hole of the base.

[0011] The load-connecting flange is fixedly connected to the main body connection end face at its bottom.

[0012] The locking pin body is detachably installed in the locking mounting groove, and the tube wall of the locking pin body is provided with ball bearing through holes.

[0013] The locking ball is radially movable and accommodated within the ball through hole;

[0014] A locking rotating shaft is slidably connected to the inside of the locking pin body, and a locking pin tapered surface is provided on the outer wall of the locking rotating shaft corresponding to the position of the ball through hole;

[0015] The locking knob is integrally fixed to the outer wall of the locking rotation shaft, and a threaded connection is provided between the locking knob and the locking pin body.

[0016] Preferably, in order to improve the symmetry and stability of positioning, the base positioning groove is symmetrically opened on the left and right sides of the outer wall of the turntable connecting seat; correspondingly, the positioning protrusion is also symmetrically fixedly connected to the left and right sides of the inner wall of the quick-release flange body, ensuring that the two achieve stable docking through double-sided symmetrical engagement.

[0017] Preferably, in order to provide a balanced locking force, the base locking holes are symmetrically opened on the front and rear sides of the outer wall of the turntable connecting seat; the front and rear sides of the outer wall of the quick-release flange body are respectively provided with locking mounting grooves, so that the locking mechanism can act simultaneously in both front and rear positions, enhancing the stability of the connection.

[0018] Preferably, the upper side of the turntable connecting seat and the lower side of the quick-release flange body are engaged and connected by a planar fit to form a stable axial reference surface. At the same time, the ball bearing set on the inner wall of the turntable connecting seat is used for the rotational support of the turntable spindle, ensuring the motion accuracy of the turntable.

[0019] Preferably, the bottom of the load-bearing flange is also fixedly connected to the bottom of the quick-release flange body, and the load-bearing flange is also fixedly connected to the main body connection end face at the top of the quick-release flange body, forming a highly rigid connection structure. The load-bearing flange is used to bear external loads.

[0020] Preferably, the specific implementation of the threaded connection is as follows: a thread, i.e., an inner circumferential thread, is machined on the inner circumference of the locking knob, and a thread, i.e., an outer circumferential thread, is machined on the corresponding position on the outer circumference of the locking pin body. The two are screwed together to realize the conversion of rotational motion to axial motion.

[0021] Preferably, the locking pin cone surface is configured as a circumferential annular inclined surface surrounding the outer wall of the locking rotating shaft. This continuous inclined surface structure ensures that a uniform radial pushing force can be applied to all locking balls regardless of the angle to which the locking rotating shaft rotates.

[0022] Preferably, the locking pin body, locking rotating shaft, locking knob and locking ball are pre-assembled into a set to form a locking pin assembly that can be pulled out as a whole from the locking mounting slot, which greatly facilitates installation, disassembly and maintenance.

[0023] Preferably, in order to prevent the locking pin assembly from accidentally sliding out in the unlocked state, the locking mounting groove and the locking pin body are connected by a snap-fit ​​connection, and slight positioning and retention are achieved by a spring or a concave-convex structure.

[0024] Preferably, in order to make the flange more evenly stressed, multiple sets of locking mounting grooves, locking pin bodies, locking rotating shafts, locking knobs, locking balls, and base locking holes are provided, and they are evenly distributed along the circumference of the quick-release flange body.

[0025] This utility model has the following beneficial effects:

[0026] 1. This utility model solves the problem in the prior art that flange installation requires tools to tighten and loosen bolts one by one, which is cumbersome, time-consuming and labor-intensive. It achieves the effect of tool-free and quick installation and removal of loads, and improves the efficiency of load replacement of servo turntable.

[0027] 2. This utility model solves the problem that traditional flanges are difficult to align accurately in one go during installation and that their torsional resistance depends on the friction of bolts by setting a snap-fit ​​connection between the positioning protrusion on the quick-release flange body and the base positioning groove on the turntable connecting seat. It achieves the effects of high positioning accuracy, good consistency of repeated installation, stable connection structure and strong torque resistance.

[0028] 3. This utility model solves the problem of loosening and detachment of connecting parts under high-speed rotation and vibration conditions of servo turntable by using the conical surface of the locking pin to push the locking ball to form a rigid radial lock. It achieves the effects of firm locking, high structural rigidity, good vibration resistance, and effective prevention of axial movement and detachment. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] Example:

[0039] Please refer to Figures 1 to 6 This utility model provides a quick-release load mounting flange for a servo turntable, which aims to solve the problem that in the prior art, most servo turntable load flanges are fastened with multiple bolts, and tools are needed to loosen or tighten them one by one when installing and removing the load, which is cumbersome, time-consuming and inefficient.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, a servo turntable quick-release load mounting flange includes a turntable connecting seat 1 and a quick-release flange body 2 detachably mounted on the turntable connecting seat 1. A ball bearing 7 is fixedly connected to the inner wall of the turntable connecting seat 1, supporting the turntable spindle. A base positioning groove 6 and a base locking hole 14 are provided on the outer wall of the turntable connecting seat 1. A positioning protrusion 5 is fixedly connected to the inner wall of the quick-release flange body 2, engaging with the base positioning groove 6. A main body connecting end face 4 is provided at the top of the quick-release flange body 2, and a locking mounting groove 8 is provided on the outer wall of the quick-release flange body 2, corresponding to the position of the base locking hole 14. The bottom of the load connecting flange 3 is fixedly connected to the main body connecting end face 4, and the load connecting flange 3 is used to bear external loads, such as... Figure 4 , Figure 5 and Figure 6 As shown, it also includes a mechanism for achieving quick locking. The mechanism for achieving quick locking includes a locking pin body 11, which is pluggably installed in the locking mounting groove 8. A ball bearing through hole is opened on the tube wall of the locking pin body 11, and the locking ball 13 is radially movable and accommodated in the ball bearing through hole. The locking rotating shaft 9 is slidably connected to the inside of the locking pin body 11. The outer wall of the locking rotating shaft 9 has a locking pin conical surface 12 at a position corresponding to the ball bearing through hole. The locking knob 10 is integrally fixedly connected to the outer wall of the locking rotating shaft 9. A threaded connection is provided between the locking knob 10 and the locking pin body 11. The rotation of the locking knob 10 drives the integrally fixed locking rotating shaft 9 to slide axially inside the locking pin body 11 through the threaded connection. The axial sliding of the locking rotating shaft 9 causes the locking pin conical surface 12 to push the locking ball 13, so that it extends radially and engages with the inside of the base locking hole 14.

[0041] To solve the aforementioned technical problems, a precision-fitting positioning mechanism and a locking mechanism are also included. These two mechanisms are respectively located at the connection interface between the quick-release flange body 2 and the turntable connecting seat 1. Please refer to [the relevant documentation / reference]. Figure 3 , Figure 4 , Figure 5 and Figure 6 The turntable connecting seat 1 has base positioning grooves 6 on both the left and right sides of its outer wall. The quick-release flange body 2 has positioning protrusions 5 fixedly connected to the corresponding positions on the left and right sides of its inner wall. The positioning protrusions 5 have a geometric shape that matches the base positioning grooves 6. In the assembled state, the positioning protrusions 5 are tightly embedded in the base positioning grooves 6. This concave-convex fit structure not only ensures the high-precision alignment of the quick-release flange body 2 with respect to the turntable connecting seat 1, but also provides circumferential anti-torque support for the quick-release flange body 2 through the abutment of the side walls, preventing the two from rotating relative to each other.

[0042] Meanwhile, locking mounting grooves 8 are provided on the front and rear sides of the outer wall of the quick-release flange body 2, and base locking holes 14 are provided on the corresponding positions on the front and rear sides of the outer wall of the turntable connecting seat 1. The locking pin body 11 has a hollow tubular structure and is inserted and fixed inside the locking mounting groove 8. A ball bearing through hole is provided through the tube wall of the locking pin body 11. The locking ball 13 is movably accommodated in the ball bearing through hole and can move radially. The locking rotating shaft 9 is coaxially slidably inserted into the internal cavity of the locking pin body 11. The outer peripheral wall of the locking rotating shaft 9 is provided with a locking pin cone surface 12 in the shape of a frustum or a slope. The locking knob 10 is fixedly connected to the locking pin body 11. The rotating shaft 9 extends out of the outer end of the locking pin body 11, and a threaded connection structure is provided between the inner wall of the locking knob 10 and the outer wall end of the locking pin body 11. By manually rotating the locking knob 10, the rotational motion is converted into the axial linear motion of the locking rotating shaft 9 relative to the locking pin body 11 through the threaded connection structure. This drives the locking pin cone surface 12 to move axially forward and backward to change the contact point diameter with the locking ball 13, forcing the locking ball 13 to be pushed out radially from the ball through hole and stuck into the base locking hole 14 to achieve rigid locking, or allowing the locking ball 13 to retract inward and disengage from the base locking hole 14 to achieve unlocking.

[0043] In one preferred embodiment, the base positioning groove 6 is formed on the left and right sides of the outer wall of the turntable connecting seat 1, and the positioning protrusion 5 is fixedly connected to the left and right sides of the inner wall of the quick-release flange body 2.

[0044] In one preferred embodiment, the base locking hole 14 is opened on the front and rear sides of the outer wall of the turntable connecting seat 1, and the locking mounting groove 8 is correspondingly opened on the front and rear sides of the outer wall of the quick-release flange body 2.

[0045] As a preferred embodiment, multiple locking mounting grooves 8, locking pin bodies 11, locking rotating shafts 9, locking knobs 10, locking balls 13, and base locking holes 14 are provided and distributed along the circumference of the quick-release flange body 2.

[0046] In a preferred embodiment, the upper side of the turntable connecting seat 1 is engaged with the lower side of the quick-release flange body 2, and the ball bearing 7 is used to support the turntable spindle.

[0047] In a preferred embodiment, the threaded connection is provided between the inner circumferential thread of the locking knob 10 and the outer circumferential thread of the locking pin body 11;

[0048] In a preferred embodiment, the locking pin cone surface 12 is a circumferential annular inclined surface surrounding the outer wall of the locking rotation shaft 9;

[0049] In a preferred embodiment, the locking mounting groove 8 and the locking pin body 11 are engaged.

[0050] In a preferred embodiment, the locking pin body 11, the locking rotating shaft 9, the locking knob 10, and the locking ball 13 together constitute a locking pin assembly that can be pulled out as a whole from the locking mounting groove 8.

[0051] Working principle: During installation, first connect the turntable connecting seat 1 to the servo machine, and install the ball bearing 7 into the inner wall of the turntable connecting seat 1. Then place the quick-release flange body 2 on the turntable connecting seat 1. The positioning protrusion 5 on the inner wall of the quick-release flange body 2 engages with the base positioning groove 6 on the outer wall of the turntable connecting seat 1 to achieve precise positioning. At this time, the locking mounting groove 8 on the quick-release flange body 2 and the base locking hole 14 on the turntable connecting seat 1 are automatically aligned.

[0052] Subsequently, the locking pin assembly, consisting of the locking pin body 11, the locking rotating shaft 9, the locking ball 13, and the locking knob 10, is inserted through the locking mounting groove 8, passes through the quick-release flange body 2, and enters the interior of the base locking hole 14. The locking knob 10 is rotated clockwise, and the locking knob 10 drives the locking rotating shaft 9, which is fixedly connected in one piece, to slide axially inside the locking pin body 11 through the threaded connection. When the locking pin cone surface 12 on the locking rotating shaft 9 moves axially, it pushes the locking ball 13, forcing the locking ball 13 to extend radially outward and tightly engage around the inner wall of the base locking hole 14, thereby firmly locking the quick-release flange body 2 onto the turntable connecting seat 1. Finally, the load connecting flange 3 is fixed in the main body connecting end face 4 at the top of the quick-release flange body 2, and the installation is completed.

[0053] When disassembly is required, turn the locking knob 10 counterclockwise. The locking rotating shaft 9 slides in the opposite axial direction under the action of the threaded connection. The locking pin cone surface 12 retracts accordingly and no longer applies radial thrust to the locking ball 13. After the constraint is released, the locking ball 13 retracts inward and disengages from the locking hole 14 of the base. At this time, the entire locking pin assembly can be pulled out from the locking mounting groove 8. The quick-release flange body 2 loses its fixation and can be lifted upward to quickly separate from the turntable connecting seat 1.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
