Description

Technical Field

[0001] The utility model relates to a thin plate clamping and positioning device, belonging to the technical field of machining fixtures. Background Art

[0002] Machining is short for mechanical processing, referring to the processing technology of removing materials through precise mechanical processing. During machining operations, it is necessary to fix workpieces with fixtures, so a large number of auxiliary fixtures are involved. These auxiliary fixtures need to be designed differently according to the product structure to meet the stable limit of product machining and improve the forming accuracy. The design of fixtures is of great significance to the machining stability, forming accuracy, and processing efficiency of products.

[0003] Currently, there is a drilling and boring operation for slender thin plate parts. The slender thin plates are used for fork structural parts, guide rail structural parts, truss support parts, etc. Traditional fixtures are mostly rigid clamping. However, the length direction of the slender thin plate is relatively poor, so there is a certain tolerance on the side, and the clamping position accuracy is poor and the stability is also poor.

[0004] In response to this situation, the Chinese utility model patent with the authorization announcement number CN 208854205 U discloses a floating fixture for thin plate processing. This floating fixture can achieve floating clamping of slender thin plates. This floating clamping is mainly horizontal and can meet the adjustment of the side tolerance of the thin plate. However, when the thin plate is machined by drilling and boring, there will be vertical tolerance and deformation, which will affect the clamping stability in the horizontal direction at this time.

[0005] The applicant proposed a Chinese invention patent with the announcement number CN116329610A for the above situation. It discloses a floating loading device for thin plate drilling and boring machining. It realizes the clamping and locking of one side of the thin plate through at least three floating locking mechanisms. The multi-point clamping and locking on the side uses a design with a common drive source. Therefore, when there is bending on the positioning reference side or there are tolerances in the workpiece itself during clamping, there will be a situation of false clamping in multi-point clamping. During the subsequent processing, the post-line accuracy of multiple holes on the thin plate is insufficient, affecting the qualified rate of finished products. Summary of the Utility Model

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0041] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0042] The utility model provides a thin plate clamping and positioning device, such as Figures 1 to 8 As shown, it includes a processing base 1 and a loading platform 2 arranged on the processing base 1. The processing base 1 is a material placement base that cooperates with the machining equipment, and the loading platform 2 is used to be mounted on the processing base 1 to replace the loading platform for carrying different workpieces. At least one loading station 3 is provided on the loading platform 2.

[0043] The loading station 3 includes a side clamp locking unit 4, a side stop fixing unit 5, and a supporting mechanism 6 disposed between the side clamp locking unit and the side stop fixing unit.

[0044] The side block fixing unit 5 includes an end locking block 51 and a side locking mechanism 52 arranged opposite to the side clamp locking unit. The side locking mechanism 52 includes at least one side limit seat 521 and at least one crimping locking portion 522. The end locking block 51 and the side limit seat 521 form a right-angle limit portion. The crimping locking portion 522 includes a power source 5221 and a crimping locking block 5222 with a lifting displacement and transmission connected to the power source.

[0045] The supporting mechanism 6 includes a plurality of thin plate supporting piles 60 which are arranged at intervals.

[0046] And as Figure 1 and Figure 2 As shown, the side clamp locking unit 4 includes two end-side floating locking mechanisms 401 arranged at intervals, and a plurality of auxiliary floating locking mechanisms 402 arranged at intervals between the two end-side floating locking mechanisms.

[0047] The end-side floating locking mechanism and the auxiliary floating locking mechanism respectively include a telescopic driving source 41 with a horizontal telescopic displacement, a locking matching seat 42 arranged on the free end of the telescopic driving source, the locking matching seat 42 is provided with a pivot locking block 43 with a pivot rotation displacement, and a torsion spring 44 transmission-connected to the pivot locking block 43, the pivot locking block 43 is provided with a horizontal fitting locking portion 431, and a pressure block 432 with a pivot deflection displacement, and the bottom of the pressure block 432 is provided with two crimping portions 430 arranged at intervals.

[0048] The telescopic drive sources of two end-side floating locking mechanisms are synchronously connected, and the telescopic drive sources of several auxiliary floating locking mechanisms are synchronously connected. The so-called synchronous connection means that the pushing drive instructions are consistent and the strokes or pushing forces are consistent.

[0049] Specific implementation process and principle description:

[0050] When carrying out thin plate machining and loading, first, position and load one end position of the thin plate with the right-angle limit part. After the thin plate is pre-loaded and limited, it is respectively positioned and abutted against the end-side locking block 51 and the side limit seat 521, and then the crimping and locking of the crimping locking part 522 and the clamping and locking of the side clamping locking unit 4 are carried out.

[0051] Specifically, during the execution process, first, the end-side floating locking mechanisms 401 at both ends carry out synchronous clamping and fixing at two points. After their first and last ends are synchronously clamped and fixed, then the power source 5221 is used to press down and lock the upper surface of one side of the thin plate by the crimping locking block 5222. At this time, relatively reliable precision alignment of the thin plate is obtained.

[0052] After its pre-loading is completed, at this time, the auxiliary floating locking mechanism 402 carries out auxiliary clamping. It is carried out after the end-side floating locking mechanism 401 and is synchronously clamped in place. In this way, auxiliary side blocking clamping can be realized, eliminating the traditional virtual clamping situation, making the thin plate processing more reliable and stable during the process, and ensuring the relative position accuracy of boring.

[0053] When pushing the end-side floating locking mechanism 401 and the auxiliary floating locking mechanism 402, in the initial state, the torsion spring 44 makes the end of the pressing block 432 in an upturned state. After the pivot locking block 43 is pushed to be horizontally attached to the locking part 431 and abutted against the side wall of the thin plate, and as it continues to advance, the pressing block 432 swings, and its two crimping parts 430 are crimped and locked with the top wall of the thin plate. When each single-point clamping is carried out, a certain self-adaptive range is also provided, which can play a certain role in tolerance self-adaptation.

[0054] In this way, the thin plate is stably locked. When drilling and boring operations are carried out, the thin plate will be subjected to a certain operating force in the vertical direction. This operating force will cause a certain deformation and bounce of the thin plate in the height direction. At this time, when the thin plate deforms downward, it will cause a certain follow-up change of the crimping part 430. In its follow-up change state, since one side of the thin plate is locked by right-angle positioning, the change amount is correspondingly floating and conforming with the horizontal attachment locking part 431, meeting the reliability of deformation follow-up and locking cooperation during the thin plate processing.

[0055] In addition, in a specific embodiment, the loading table 2 is provided with a matching support table corresponding to the pressing block 432 one by one. The support surface of the matching support table and the support surface of the thin plate support pile platform 60 are located on the same horizontal plane, so that the fixed-point crimping of multiple pressing blocks 432 is more reliable and stable.

[0056] In a specific embodiment, the pushing forces of the telescopic driving sources of the two end-side floating locking mechanisms are consistent, and the pushing forces of the telescopic driving sources of several auxiliary floating locking mechanisms are consistent.

[0057] The pushing force of the telescopic driving source of the end-side floating locking mechanism is greater than the pushing force of the telescopic driving source of the auxiliary floating locking mechanism.

[0058] Specifically, the end-side floating locking mechanism 401 is used to clamp the two end positions of the side edge of the thin plate, and the two cooperate to lock and clamp in place, that is, the two end positions of the side edge are tightly locked.

[0059] The auxiliary floating locking mechanism 402 is used for auxiliary clamping, that is, to provide the clamping and locking stability of the middle part of the thin plate so as to eliminate the accuracy loss caused by its deformation. Through the limitation of its pushing force, when it is used for auxiliary clamping, while playing a single-point pressure maintaining and locking function, it will not generate an acting force offset effect on the end-side floating locking mechanism, so as not to cause the problem of the missing clamping position degree of the end-side floating locking mechanism, and effectively guarantee the machining operation accuracy.

[0060] In a specific embodiment, the telescopic driving source 41 and the power source 5221 are respectively hydraulic cylinders. The hydraulic cylinders of the two end-side floating locking mechanisms are connected to the first hydraulic source 100, the hydraulic cylinders of several auxiliary floating locking mechanisms are connected to the second hydraulic source 200, and the hydraulic cylinder of the crimping and locking part is connected to the third hydraulic source 300.

[0061] The bottom of the material loading table 2 is provided with a first hydraulic pipeline 21 that cooperates with the first hydraulic source, a second hydraulic pipeline 22 that cooperates with the second hydraulic source, and a third hydraulic pipeline 23 that cooperates with the third hydraulic source.

[0062] Specifically, using hydraulic cylinders can achieve synchronous drive and control of the pushing force. Of course, the solution of using cylinders with the same source and the same pressure control is also within the protection scope of this case. In addition, it can also be realized by using a servo motor to drive a lead screw in cooperation with a pressure sensor. As long as it can meet the driving structure of the differential operation of the end-side floating locking mechanism 401 and the auxiliary floating locking mechanism 402, it is within the protection scope of this case.

[0063] In order to facilitate the installation of the first hydraulic pipeline 21, the second hydraulic pipeline 22, and the third hydraulic pipeline 23, corresponding pipeline arrangement grooves can be provided at the bottom of the material loading table 2 to meet the pipeline arrangement requirements.

[0064] Refer to Figure 1As shown, an intermediate arrangement groove and two side arrangement grooves located on both sides of the intermediate arrangement groove are formed at the bottom of the material loading table 2. Among them, the side arrangement grooves are used to carry the first hydraulic pipeline 21 and the second hydraulic pipeline 22, and the intermediate arrangement groove is used for the third hydraulic pipeline 23. There are through pipeline channels in both the intermediate arrangement groove and the two side arrangement grooves, which are convenient for hose connection and cooperation to form their respective liquid circuit return lines.

[0065] In a specific embodiment, the floating locking mechanism 40 includes a displacement adjustment carrier 401 for carrying a telescopic driving source. The telescopic driving source is provided with a linear adjustment displacement on the displacement adjustment carrier. A positioning tooth row 402 is provided on the displacement adjustment carrier, and a positioning tooth row for meshing with the positioning tooth row is provided at the bottom of the telescopic driving source. An interlocking portion is provided between the displacement adjustment carrier and the telescopic driving source.

[0066] Specifically, the telescopic driving source 41 has a certain telescopic variation range, and the thin plate has a certain width range. Through the displacement adjustment carrier 401, the position adjustment of the telescopic driving source can be realized to meet the matching requirements of different specifications of thin plates, and the positioning tooth row 402 and the interlocking portion meet the requirements for the fixed stability of the telescopic driving source.

[0067] In a specific embodiment, two sets of centrally symmetrically arranged material loading stations 3 are provided on the material loading table 2, and the two material loading stations share a side locking mechanism 52.

[0068] The side locking mechanism 52 includes two crimping locking portions 522 respectively arranged on both sides of the side limiting seat 521. Two spaced loading grooves 5210 are provided on the side limiting seat. A side locking block with two limiting ends is detachably arranged in the loading groove. The crimping locking block has a rotational displacement, and the crimping locking block 5222 has two crimping cooperation rods respectively corresponding to and cooperating with the material loading stations.

[0069] Specific implementation process and principle description:

[0070] Generally, the thin plates are paired workpieces, and there are multiple workpiece machinings with zero point as the reference during machining to ensure the forming unity of multiple groups of workpieces, that is, the machining parameters and strokes of multiple workpieces with zero point are referenced with zero point.

[0071] In this case, first, the central symmetry meets the zero point reference requirement. In addition, the two material loading stations 3 share the side locking mechanism 52, which can realize relative positioning and limiting on the side, and cooperate with the floating to make the deformation amounts in the machining processes of the two unified, and the relative forming unity is guaranteed.

[0072] In a specific embodiment, the material loading table 2 has an adjustment displacement along the direction of the interval arrangement of the thin plate support piles on the machining base 1, and a positioning portion 20 is provided on the material loading table 2.

[0073] Specifically, the adjustment displacement of the material loading table 2 is used for zero correction, and zero positioning can be achieved through the positioning part 20, so that the initial alignment adjustment is smoother and more efficient. There is no need to perform complex zeroing alignment adjustment.

[0074] In a specific embodiment, a supporting and positioning table 7 is provided at the bottom of the material loading table 2. The supporting and positioning table 7 is slidably arranged on the processing base 1, and the positioning part is arranged on the supporting and positioning table.

[0075] That is, through the supporting and positioning table 7, the material loading table 2 can be conveniently changed in type, and at the same time, it is easy to adjust the position and position locking on the processing base 1.

[0076] In a specific embodiment, a detachable matching mechanism 8 is provided between the material loading table 2 and the supporting and positioning table 7; the detachable matching mechanism 8 includes at least three positioning and locking piles 81 arranged on the supporting and positioning table, and locking matching parts 82 arranged at the bottom of the material loading table and corresponding to the positioning and locking piles one by one.

[0077] Specifically, generally, the supporting and positioning table 7 is positioned on the processing base 1 through T-shaped bolts. When loading and unloading materials, the thin plate on it is replaced.

[0078] And there are various specifications of thin plates. Therefore, through the detachable matching mechanism 8, the material loading table 2 can be replaced, and the positioning part 20 on the supporting and positioning table 7 itself also meets the zero position adjustment requirements.

[0079] The detachable matching mechanism 8 is described. The positioning and locking pile 81 can be provided with a profiling matching groove, and the locking matching part 82 is a mortise and tenon matching part matching with the profiling matching groove. The two are fixed by means of magnetic adsorption or bolt locking, etc., so as to meet the requirements of high-efficiency operation and type change.

[0080] Through the above description, it can be found that in a thin plate clamping and positioning device of the present invention, the loading position accuracy is guaranteed by limiting and tightly locking both ends of one side of the thin plate, and the middle positioning can be maintained by intermediate auxiliary limiting and locking. In this way, the loading position accuracy of the thin plate is improved, and the machining qualification rate is significantly improved. It meets the requirements of the same-stage loading and processing operations of paired workpieces with central symmetry, and the relative machining forming uniformity is guaranteed. It can realize the high-efficiency type change and loading positioning of the material loading table, the type change is efficient, smooth and reliable, meets the rapid positioning requirements after type change, and there is no need for secondary calibration and positioning.

[0082] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
