Description

Technical Field

[0001] This utility model relates to the field of processing equipment for threaded products, and in particular to an integrated sorting device for through-threaded internal thread products. Background Technology

[0002] Internal thread products are common and are used in conjunction with other bolts or studs. In this case, it is essential to ensure that the internal diameter, thread dimensions, and other specifications of the internal thread product meet the requirements. A current problem in the machining industry is:

[0003] 1. In the nut tapping process of the cold heading industry, due to the influence of many factors such as equipment precision, cutting speed and feed rate, and tap chip removal, iron filings may occasionally stick to the thread wall after tapping, causing the minor diameter of the thread to be blocked.

[0004] 2. Due to operator negligence, mechanical reasons, and the influence of turnover between processes, occasionally unprocessed products may be mixed into processed products.

[0005] 3. Misalignment of the tapping machine spindle causes misalignment of the threads after tapping.

[0006] The above three defects are all sporadic occurrences. The number of samples inspected by personnel during the production process is limited, making it impossible to completely avoid defects. Furthermore, occasional omissions during subsequent manual sorting may reach the customer, causing assembly problems and resulting in losses for the customer. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides an integrated sorting device for through-threaded products.

[0008] The technical solution of this utility model is: an integrated sorting device for through-threaded products, comprising:

[0009] Select workbench;

[0010] The detection feeding channel is set within the detection feeding channel of the sorting workbench, where multiple workpieces to be tested are arranged.

[0011] The detection bar includes, from top to bottom, a small diameter selection section, a material storage section, a thread selection section and a discharge section. The upper end of the detection bar is connected to the detection feeding channel, and the workpiece to be tested enters the detection bar for detection under the action of gravity.

[0012] A detection discharge channel is provided, which is located on the sorting worktable and below the detection bar; and

[0013] The detection drive unit includes a drive motor, which is mounted on the sorting worktable via a drive bracket. A drive pressure roller is mounted on the output end of the drive motor. The drive pressure roller presses the workpiece to be tested against the thread sorting section and drives the workpiece to be tested to rotate.

[0014] Furthermore, the detection rod is made of high-speed steel.

[0015] Furthermore, the minor diameter separation section is 1.3-1.8 times the product length;

[0016] The material storage section is 1.5 times the length of the product;

[0017] The thread selection section is 0.5 times the product length.

[0018] Furthermore, it also includes a guide rod, the diameter of which is smaller than that of the detection rod, and the guide rod is positioned between the detection feeding channel and the detection rod. The guide rod ensures that the workpiece to be tested can smoothly enter the detection rod.

[0019] Furthermore, a guide mounting groove is provided at the upper end of the detection rod, and a guide rod is placed within the guide mounting groove. This facilitates smooth connection between the two components and allows for easy disassembly and reassembly.

[0020] Furthermore, the guide rod is bent, which allows for smooth horizontal feeding and vertical detection. It also enables the transport of workpieces to be tested from different directions.

[0021] Furthermore, the upper end of the detection rod is provided with an inlet ramp that tapers from the outside in, ensuring smooth and stable entry of the workpiece into the detection rod.

[0022] Furthermore, a support member, which is a magnetic support, is provided on the outside of the discharge section of the detection rod. Since the detection rod is lightweight, supporting magnetic poles can be installed on the sorting worktable or the detection discharge channel, and an axial magnetic pole can be installed at the lower end of the detection rod. Both are at the same height, and the supporting magnetic pole attracts the axial magnetic pole, preventing the detection rod from falling.

[0023] Furthermore, a support brush is provided, with at least one support brush located on the outer side of the thread selection section. The support brush ensures stable detection of the workpiece in the thread selection section. Additionally, if a special workpiece requires stable support in multiple directions, two or more support brushes can be provided as needed.

[0024] Furthermore, the length of the support brush is greater than the length of the threaded inspection section. It is generally set at 2-3 times.

[0025] Furthermore, it also includes a vibrating feeder, which is connected to the detection and feeding channel. Vibrating feeding or rotary drum feeding are conventional feeding methods, so they will not be described in detail.

[0026] Furthermore, the detection feeding channel includes a V-groove section and a cylindrical section.

[0027] Furthermore, the detection discharge channel is L-shaped. This shape design allows for a certain degree of cushioning when the detected workpiece falls, preventing damage to the workpiece, and the workpiece is received through the discharge port of the detection discharge channel.

[0028] Furthermore, the detection bar features an angled design between its segment thread center axis and PIN center axis, allowing for the selection of skewed threads and achieving a 0.2% selection capability with full runout of the internal thread and vertical end face. Simultaneously, the detection bar can be mounted on a magnetically controlled rotating sorting device, enabling the integration of multiple sorting categories.

[0029] The beneficial technical effects of this utility model are as follows: Through ingenious design and the selection of high-speed steel material, the three selection criteria are integrated into one, reducing the selection process and time. It can automatically screen for defects such as minor diameter deviation, missing threads, and thread skew, achieving a selection speed of 80 samples per minute. This improves product stability and provides a reliable guarantee for subsequent installation. Attached Figure Description
