Abstract
Description
Technical Field
[0001] This utility model relates to the field of indexing plate technology, specifically to a high load-bearing indexing plate. Background Technology
[0002] In fields such as CNC machine tools, heavy machinery assembly, and large parts inspection, the indexing plate, as a core component for achieving precise positioning and rotation of workpieces in multiple workstations, directly determines the quality and efficiency of processing or inspection through its load-bearing capacity and indexing accuracy.
[0003] Existing indexing plates generally suffer from the following technical defects: the base of traditional indexing plates is mostly made of ordinary cast iron, and the structural design lacks targeted reinforcement support, resulting in poor load-bearing capacity; moreover, the indexing plate is often difficult to disassemble from the base, which makes it difficult to replace the indexing plate when it is necessary to change the number of fixing parts at the top of the indexing plate, thus limiting the use of the indexing plate. Utility Model Content
[0004] The main objective of this invention is to provide a high-load-bearing indexing plate to solve the aforementioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-load-bearing indexing plate, comprising an indexing plate and a base, a support plate being provided between the indexing plate and the base, and a plurality of support rods arranged circumferentially within the support plate; a plurality of fixing grooves arranged circumferentially on the top surface of the base, and fixing components being provided within the fixing grooves; a plurality of fixing seats arranged circumferentially on the outer side wall of the indexing plate, and a limiting cylinder being provided at the bottom of the fixing seat; the outer side wall of the limiting cylinder being slidably connected to the inner side wall of the fixing groove.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the fixing component includes a first support block fixed on the bottom wall of the fixing groove, a first inclined guide block is provided on the top of the first support block, a second support block is fixed on the top of the first inclined guide block, and an arc-shaped limiting seat is fixed on the top of the second support block; an integrally formed second inclined guide block and a third inclined guide block are slidably installed on the outer periphery of the second support block.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a strip groove is opened in the inner cavity of the limiting cylinder, a spring component is provided in the strip groove, and an arc-shaped limiting block is fixed at one end of the spring component; the top of the arc-shaped limiting block can abut against the bottom of the arc-shaped limiting seat.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the arc-shaped surface of the arc-shaped limiting block can slide relative to the arc-shaped surface of the arc-shaped limiting seat; the arc-shaped surface of the arc-shaped limiting block can slide relative to the inclined surfaces of the second inclined guide block and the third inclined guide block.
[0009] The beneficial effects of this utility model are as follows: In this embodiment, the three-layer structure of the indexing plate, the support plate, and the base is combined with the support rods arranged in a circumferential array within the support plate; compared with the traditional design of the indexing plate relying only on a single point of support at the base, this structure can transfer the weight through the indexing plate to the support plate, and then distribute it to the base through the circumferentially evenly distributed support rods, avoiding cracking of the base caused by local stress concentration, and thus having a higher load-bearing capacity; the setting of the fixing components facilitates the disassembly between the indexing plate and the base.

Detailed Implementation
[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0012] See attached diagram. Figures 1 to 2 In this embodiment, a high-load-bearing indexing plate includes an indexing plate 1 and a base 2. A support plate is provided between the indexing plate 1 and the base 2. Several support rods 6 are arranged in a circumferential array inside the support plate. Several fixing grooves 5 are arranged in a circumferential array on the top surface of the base 2. Fixing components are provided in the fixing grooves 5. Several fixing seats 3 are arranged in a circumferential array on the outer side wall of the indexing plate 1. A limiting cylinder 4 is provided at the bottom of the fixing seat 3. The outer side wall of the limiting cylinder 4 is slidably connected to the inner side wall of the fixing groove 5.
[0013] In the above scheme, the fixing component includes a first support block 7 fixed on the bottom wall of the fixing groove 5, a first inclined guide block 70 is provided on the top of the first support block 7, a second support block 73 is fixed on the top of the first inclined guide block 70, and an arc-shaped limiting seat 74 is fixed on the top of the second support block 73; an integrally formed second inclined guide block 71 and a third inclined guide block 72 are slidably installed on the outer periphery of the second support block 73.
[0014] In the above scheme, a strip groove is opened in the inner cavity of the limiting cylinder 4, and a spring member 40 is provided in the strip groove. An arc-shaped limiting block 41 is fixed at one end of the spring member 40; the top of the arc-shaped limiting block 41 can abut against the bottom of the arc-shaped limiting seat 74.
[0015] In the above scheme, the arc-shaped surface of the arc-shaped limiting block 41 can slide relative to the arc-shaped surface of the arc-shaped limiting seat 74; the arc-shaped surface of the arc-shaped limiting block 41 can slide relative to the inclined surfaces of the second inclined guide block 71 and the third inclined guide block 72.
[0016] In this embodiment, the three-layer structure of indexing plate 1, support plate and base 2 is combined with the support rods 6 arranged in a circumferential array inside the support plate. Compared with the traditional indexing plate design that only relies on a single point of support on the base, this structure can transfer the weight to the support plate through the indexing plate, and then distribute it to the base 2 by the circumferentially evenly distributed support rods 6, avoiding the base cracking caused by local stress concentration, and has a higher load-bearing capacity. When the limiting cylinder 4 slides down the fixing groove 5, the arc-shaped limiting block 41 inside the limiting cylinder 4 first contacts the arc-shaped limiting seat 74. Under the guidance of the arc-shaped inclined surface, the fixing groove 5 continues to slide down. At this time, the arc-shaped limiting block 41 is pressed and the spring 40 is compressed until the top of the arc-shaped limiting block 41 can abut against the bottom of the arc-shaped limiting seat 74, and the spring 40 returns to its initial state. When the indexing plate needs to be disassembled, continue to slide down the fixing groove 4, so that the arc-shaped limiting block 41 slides along the third inclined guide block 72 to the second inclined guide block 71. At this time, under the action of the spring 40, the arc-shaped limiting block 41 can slide along the second inclined guide block 71, driving the integrally formed second inclined guide block 71 and the third inclined guide block 72 to slide upward. When the third inclined guide block 72 moves to the bottom of the arc-shaped limiting seat 74, the inclined limiting block 41 can slide out of the fixing groove 5 along the arc-shaped inclined surface of the arc-shaped limiting seat 74, thereby realizing disassembly. Furthermore, both the limiting cylinder 4 and the fixing groove 5 are provided with through holes 90, and the fixing groove 5 is threaded with a push rod 8; while the second support block 73 is provided with a limiting hole 9, which can be inserted into the arc-shaped limiting block 41; when unlocking, the arc-shaped limiting block 9 can be pushed out by rotating the push rod 8 and inserting one end into the limiting hole 9.
[0017] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
