Description

Technical Field

[0001] The utility model relates to the field of tooling fixtures, in particular to a turnover tooling for a needle bed base. Background Art

[0002] During the processing of the needle bed base, due to the structure of the needle bed base itself, multiple angular surfaces need to be processed, so the needle bed base needs to be turned over. Existing turning methods mostly use manual crowbars to forcefully turn over, which is mostly for needle bed bases with relatively light self-weight, or use a horizontal lathe to hang a sling hook, hook the window of the needle bed base, lift it, and then lower it to change the angle of the needle bed base by its own gravity to achieve the purpose of turning over. This method is mostly for needle bed bases with relatively heavy self-weight. For the above two methods, it is easy to lose control when manually turning and putting down, or the hook of the horizontal lathe will become unhooked when lowering, resulting in the direct fall of the needle bed base. In both cases, there are risks such as deformation and fracture of the processing dimensions and injury to personnel. Content of the Utility Model

[0003] The main technical problem solved by the utility model is to provide a turnover tooling for a needle bed base, which can facilitate the turnover of the needle bed base and reduce the accident risk during the turnover process.

[0004] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a turnover tooling for a needle bed base, the turnover tooling for the needle bed base includes: a cross beam, a lifting ring is installed on the rod body of the cross beam, the rod body of the cross beam matches the length of the needle bed base, and turnover hoisting mechanisms are symmetrically installed at both ends of the cross beam; each turnover hoisting mechanism includes a transmission belt, an upper pulley, a lower pulley, an upper shaft seat and a clamping structure for the needle bed base. The upper shaft seat is installed at the end of the cross beam, the wheel shaft of the upper pulley is fixed on the upper shaft seat, the upper pulley can rotate around the wheel shaft, the upper pulley and the lower pulley are connected by a transmission belt, and a clamping structure for the needle bed base is installed inside the lower pulley.

[0005] In a preferred embodiment of the utility model, end plates are further installed at both ends of the rod body of the cross beam, and the upper shaft seat is fixed on the corresponding end plate.

[0006] In a preferred embodiment of the utility model, a dust-proof cover is further installed on the upper shaft seat.

[0007] In a preferred embodiment of the utility model, the diameter of the upper pulley is smaller than the diameter of the lower pulley.

[0008] In a preferred embodiment of the present utility model, the clamping structure of the needle bed base includes a support base and a clamping seat. The support base is fixed to the inner side of the lower pulley body through a connecting shaft that penetrates the lower pulley body and the bottom of the support base. The top surface of the support base is provided with a lower positioning groove that matches the end structure of the needle bed base. The bottom surface of the clamping seat is provided with an upper positioning groove that matches the end structure of the needle bed base. The bottom surface of the clamping seat and the top surface of the support base are relatively connected by bolts to clamp the end of the needle bed base. The length of the top surface of the support base is greater than the diameter of the lower pulley.

[0009] The beneficial effects of the present utility model are as follows: The present utility model can be hung on the cross car through the hanging rings on the cross beam. Two groups of transmission belts are used to connect the upper pulley on the hoisting cross beam and the lower pulley with the clamping structure of the needle bed base. The two ends of the needle bed base are clamped by the clamping structure of the needle bed base. In this way, when hoisting, the cross beam bears the weight of the main body of the needle bed base, and the rotation center and the center of gravity of the needle bed base are on the same line. In this way, the needle bed base can be easily rotated to any angle and then lowered and placed on the corresponding working station. On the one hand, this can effectively eliminate the defects of the traditional flipping method, reduce the losses caused by product deformation and fracture, and avoid the occurrence of corresponding safety accidents. On the other hand, less force is required during rotation, the action is stable, and the labor intensity is significantly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3 , the embodiments of the present utility model include:

[0020] A flipping tooling for a needle bed base, the flipping tooling for the needle bed base includes: a cross beam 2, two lifting rings 201 are symmetrically installed on the rod body of the cross beam 2, the length of the rod body of the cross beam 2 matches the length of the needle bed base 1, and flip-over hoisting mechanisms are symmetrically installed at both ends of the cross beam 2; each flip-over hoisting mechanism includes a transmission belt 5, an upper pulley 4, a lower pulley 3, an upper shaft seat 7 and a clamping structure for the needle bed base, the upper shaft seat 7 is installed at the end of the cross beam 2, the axle of the upper pulley 4 is fixed on the upper shaft seat 7, the upper pulley 4 can rotate around the axle, the upper pulley 4 is connected to the lower pulley 3 through the transmission belt 5, and a clamping structure for the needle bed base is installed inside the lower pulley 5.

[0021] End plates 202 are also installed at both ends of the rod body of the cross beam 2, and the upper shaft seat 7 is fixed on the corresponding end plate 202. Installing the upper shaft seat 7 at the end of the cross beam 2 through the end plate 202 as an intermediary can prevent the upper shaft seat 7 from being passively stressed during the rotation of the upper pulley 4 and transmitting the force to the rod body of the cross beam 2, resulting in instability of the upper shaft seat 7. Moreover, a dust-proof cover 6 is also installed on the upper shaft seat 7. Covering the upper pulley 4 with the dust-proof cover 6 can prevent dust from entering the bearing and affecting the smoothness of rotation.

[0022] The diameter of the upper pulley 4 is smaller than the diameter of the lower pulley 3. In actual implementation, generally, the lower pulley 3 is three times the upper pulley 4. The reason for adopting this structure is that in this way, when hanging, the transmission belt 5 can form a stable triangular structure with a smaller upper part and a larger lower part, and the needle bed base 1 will not sway left and right or even automatically flip when the cross beam 2 drives the entire needle bed base 1 to move.

[0023] The clamping structure for the needle bed base includes a support seat 303 and a clamping seat 304. The support seat 303 is fixed inside the lower pulley body 302 through a connecting shaft 301 passing through the lower pulley body 302 and the bottom of the support seat 303. A lower positioning groove matching the end structure of the needle bed base 1 is provided on the top surface of the support seat 303, an upper positioning groove matching the end structure of the needle bed base 1 is provided on the bottom surface of the clamping seat 304, and the bottom surface of the clamping seat 304 is relatively connected to the top surface of the support seat 303 through bolts to clamp the end of the needle bed base 1. The length of the top surface of the support seat 303 is greater than the diameter of the lower pulley 3. With this structure, the support seat 303 and the clamping seat 304 can effectively fix the end of the needle bed base 1, so that when flipping is required, the posture of the flipped needle bed base 1 can remain stable and will not fall to the ground.

[0024] The tooling described in this embodiment is a special tool for the processing of the bedplate base 1. During the actual processing, the beam 2 can be driven by the lifting ring 201 to transfer the bedplate base 1 suspended below between different processing stations. When flipping is required, only the edge of the bedplate base 1 needs to be toggled to achieve the overall flipping action of the bedplate base 1, which is convenient and fast.

[0025] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
